Methods used in Cyber warfare and cyber attacks

Just like other warfare, Cyber warfare is a digital war where computer viruses are sent instead of army and hacking into database with the aim to create damages and destruction. With the increasing use of computer and technology in almost every field obstruction of data can be a bigger war than an actual war. Acquiring sensitive data about a country, business, person or anything that relies in computational functions are in risk if the data is lost which can cause metamorphosis of a certain company that relies hugely on computer. There are diverse methods that various people or nations, for a set of diverse reasons, can damage computers or information network. Cyber-attack is a broad picture of cyber warfare, similar types of methods are used in cyber warfare and cyber-attack. When a nation’s database or the system of one of its branches is attacked for war reasons or for manipulation, the term cyber warfare is used. Comment by R Daniel Creider: Why is this text in bold? You need both an abstract and an introduction. You should have place holders in the draft to indicate that those sections of the paper have not been written.

Cyberwarfare is, therefore, a long period of cyberattacks carried out now and then, and at some point, it includes traditional military actions between countries. The fact, however, is that to date, the actual act hasn't taken place. But many states have had an eye for an eye military-cyber action, and a good example is the cyber-attack launched by the US against the Iranian Weapons as retaliation for US drone Iranian shot down. This paper looks at the primary methods used in cyber warfare and cyber-attacks.

The increasing technology is not causing mass destruction to business organizations, but to critical government agencies to. Cyberattacks and cyberwarfare are at the center of every threat that information technology possesses to the government agencies. Those running the ICT sector as experts still have several debates as per the actual meaning/definition of cyberwarfare, some look at it as misnomer arguing that up-to today, no cyberattack qualifies as an act of war and those that have occurred is within the international relations domain. Although there is no clear definition or meaning of what cyber warfare and cyber-attacks are, the world's top super nations are in the race of running active operations as ways of an offensive and defensive mechanism

There are diverse methods that various people or nations, for a set of diverse reasons, can damage computers or information networks. In a broad picture, espionage is one of the cyber-attacks, espionage in literal meaning refers to the practice of spying. Spying using a computer falls under cyber-attack. Another type is sabotage, sabotage is the act of destroying data. Changing the propaganda digitally is another type of cyber-attack. Disruption of economy is another huge concerned area of cyber-attack.

Malware in commonly known as computer virus. “Malware is a term used to describe malicious software, including spyware, ransomware, viruses, and worms. Malware breaches a network through a vulnerability, typically when a user clicks a dangerous link or email attachment that then installs risky software” [1]. Malware is the most common and the most dangerous type of a cyber-attack. Malware can be of many types and they are sent by hackers intending to block and/or change network keys or settings, damage information from a computer or a network of computers, sabotage and most importantly disable a system. Comment by R Daniel Creider: This is not APA format for in text citations.

Types of cyber attacks

Espionage: many still think that Espionage is not an act of war, but the fact it causes tension among countries. It is a form of cyber-attack that involves abstaining confidential data without the consent of the owner of the information (Kafol & Bregar, 2017). Examples of Espionage is the massive act of spying on other countries by the American government as an ICT hacker Edward Snowden revealed. Comment by R Daniel Creider: This should be a complete sentence and the first word of the sentence is capitalized.

Sabotage: this form of cyber-attack involves using computer and satellites system to coordinate and run operations leading to a severe disruption of other networks, including the military systems like C4ISTAR that run and control communications. As a cyber-attack, Sabotage leads to the interception of crucial communication or malicious replacement of the intended transmission. Other things that get affected by a Sabotage attack are; water, transportation, power, and fuel infrastructures.

Propaganda: a cyber-propaganda refers to efforts by one nation to control another nation's information in any way possible and use the information in managing the general public opinion (Goswami, 2018). To a high degree, cyber propaganda is psychological warfare; the only difference is that it uses websites that run fake news, social media platforms, and other internet platforms. Jowett & Donnell (2018) state that "propaganda is the deliberate, systematic attempt to shape perceptions, manipulate cognitions, and direct behavior to achieve a response that furthers the desired intent of the propagandist" (p. 7). Comment by R Daniel Creider: Page number is not needed.

Economic disruption: this form of cyber-attack targets economic infrastructures such as manufacturing companies, processing industry, and other aspects of the economy. An excellent example of economic disruption is the Wanna-Cry attacks that affected Ukraine and UK, s N.H.S, Merck pharmaceuticals, Maersk shipping, and other organizations globally. Economic disruption is a cyber-crime and financial crime in particular.

Surprise Cyber Attacks: this kind of attack involves using malware such as antivirus to attack communications systems, information systems, and other software that is operated by a particular organization.

Denial of service (DoS) and distributed denial of service (DDoS) is, as the name suggests, a type of cyber-attack that denies a user form getting into an online system or database. “A denial-of-service attack floods systems, servers, or networks with traffic to exhaust resources and bandwidth. As a result, the system is unable to fulfill legitimate requests. Attackers can also use multiple compromised devices to launch this attack” [1].

SQL injection is a type of cyber-attack where the attacker uses SQL code to acquire any sort of information from a computer. “A Structured Query Language (SQL) injection occurs when an attacker inserts malicious code into a server that uses SQL and forces the server to reveal information it normally would not. An attacker could carry out a SQL injection simply by submitting malicious code into a vulnerable website search box” [1].

Man-in-the-middle attack is the type of cyber-attack that interrupts or attacks a computational communication. An attacker inserts himself in a conversation between two parties, either personal communication or interaction between a user and an application making it appear like a normal conversation. “Man-in-the-middle (MitM) attacks, also known as eavesdropping attacks, occur when attackers insert themselves into a two-party transaction. Once the attackers interrupt the traffic, they can filter and steal data.

Two common points of entry for MitM attacks:

1. On unsecure public Wi-Fi, attackers can insert themselves between a visitor’s device and the network. Without knowing, the visitor passes all information through the attacker.

2. Once malware has breached a device, an attacker can install software to process all of the victim’s information” [1]. Comment by R Daniel Creider: Why are you switching the format of the in text citation? Are you quoting a quote from an article? Where is the beginning of this quote?

Phishing is the type of attack that is intended in stealing login credentials, credit card information or any other information that is saved in a browser or an application. “Phishing is a cyber-attack that uses disguised email as a weapon. The goal is to trick the email recipient into believing that the message is something they want or need — a request from their bank, for instance, or a note from someone in their company — and to click a link or download an attachment” [2].

There could be a million reasons for a person or group of people to involve themselves in cyber warfare or cyber-attacks. Acquiring information about a country could ruin a country’s prestige and could allow power to the wrong people. As an example, many countries use electronic methods for voting, if a voting system is hacked power of that country can belong to anyone. There could be military reasons for cyber warfare, for two rival nations knowing the next move of your rival can play a vital role in a war situation. If communication system between the military and the government can be hacked that will put a whole country into threat. Manipulation of a country’s database can ruin the information that they have about their citizens. “Offensive cyber operations offer a large variety of cheap and risk-free options to weaken other countries and strengthen their own positions. Considered from a long-term, geostrategic perspective, cyber offensive operations can cripple whole economies, change political views, agitate conflicts within or among states, reduce their military efficiency and equalize the capacities of high-tech nations to that of low-tech nations, and use access to their critical infrastructures to blackmail them” [3].

Military in many countries have a department of cyber security, they recruit people to save and/or attack different nations for military purposes. “Examples of cyberwarfare driven by political motivations can be found worldwide. In 2008, Russia began a cyber-attack on the Georgian government website, which was carried out along with Georgian military operations in South Ossetia. In 2008, Chinese 'nationalist hackers attacked CNN as it reported on Chinese repression on Tibet” [3]. There have been rumors of Russia attacking US presidential election held on 2016. “The Senate Intelligence Committee concluded Thursday that election systems in all 50 states were targeted by Russia in 2016, an effort more far-reaching than previously acknowledged and one largely undetected by the states and federal officials at the time” [4]. “The US Department of Justice has charged 12 Russian intelligence officers with hacking Democratic officials in the 2016 US elections” [5]. Countries attacking other countries digitally is not fresh news. There have been instances where powerful countries have used technological means to attack a rival country. There might be a lot of activities that never made it to the news channels. “Computers and satellites that coordinate other activities are vulnerable components of a system and could lead to the disruption of equipment Compromise of military systems, such as C4ISTAR components that are responsible for orders and communications could lead to their interception or malicious replacement. Power, water, fuel, communications, and transportation infrastructure all may be vulnerable to disruption” [3].

Preparedness

The increase in cyber-attacks has driven countries into conducting activities that will increase their readiness and create new strategies. The preparedness mechanism runs as war games. Since 2010, CCDCE (Cooperative Cyber Defense Centre of Excellence) which is part of NATO, has conducted annual war game known as Locked Shield as part testing readiness and improving strategic techniques, skills, and the operation decision making for all the national organizations of the participating nations. The 2019 war games brought together 1200 competitors from thirty nations who competed as Blue team vs Red team. The 2019 game was unique as it included Beryllia a fictional nation facing deteriorating cyber security situation.

Cyber counterintelligence

The cyber counterintelligence refers to measures of identifying, penetrating/neutralizing any form of foreign operation that runs through cyber operations as a primary threat control method. The process also includes neutralizing foreign intelligence by gauging the capabilities of cyber threats and motives. The U.S government invest millions of monies in cyber counter intelligence, since 2009, the federal government spends over $100 million in responding and repairing the network systems damaged by several cyber-attacks that target the country’s top security communication networks. The U.S lawmakers are also part of the support system in the war against cyber-attacks and they first showed in 2009 by pushing the White House to appoint a cyber-attack specialist as way of dramatically escalating the country’s defense system against any form of cyber threats, crafts proposals to empower the government in setting the best security mechanism to protect private industry.

The US Department of Defense is also in the race of ensuring that the country develops counterattack system. in 2015, the department made public a memorandum that detailed several tactics that will ensure the country remains prepared to face the cyber-attack threats. One of the most challenging issue in cyber counterintelligence is attributing the problem to a parson or system of operation. It is almost impossible to figure the person behind any form of cyber-attack, although the defiance secretary of defense maintains that as a country, we have the best systems to trace an attack back to the source. As a country that runs some of the world’s top military system, the Pentagon has continuously prosed various ways of ensuring that the country has the best including the prosed deployment of the country’s top ICT experts and hackers to military operation bases.

What is the problem? A literature review on challenges facing the communication of nanotechnology to the public

Abstract Ethical and societal issues concerning justice, safety, risks, and benefits are well-established topics in the discourses of nanotechnology innovation and devel- opment. That nanotechnology innovation should be so- cially and ethically responsible is generally accepted by scientists, policymakers, regulators, and industry, and the idea of public involvement and communication is part and parcel of the conceptualization of responsible technology development. This paper systematically re- views the social science research literature accumulated between 2002 and 2018 on the communication of nano- technology. A critical and constructivist perspective on policy problems guides the analysis. Two questions are asked of this literature: what problems are identified regarding the communication of nanotechnology to the public? How can these problems be managed and/or resolved? Three different problem themes are identified: the public, societal institutions, and nanotechnology itself. While for some identified problems, there are corresponding solutions; in other instances, there is little alignment between problems and solutions. In conclu- sion, the paper recommends that in communicating

nanotechnology to the public: (i) the objectives of com- munication should be defined; (ii) previous research should be used responsibly; (iii) communication strate- gies should be adapted to the context; and (iv) effort should not be spent trying to develop a generic frame- work for communication.

Literature review

Introduction

When nanotechnology hype began to mount almost two decades ago, it was readily recognized that to reach its full revolutionary potential, nanotechnology develop- ment had to be Bresponsible^ (Macnaghten 2010; Pidgeon et al. 2011). The gigantic National Nanotechnology Initiative (NNI), established in the year 2000 in the United States (US), declared that Bnanotechnology is helping to considerably improve, even revolutionize, many technology and industry sec- tors: information technology, energy, environmental sci- ence, medicine, homeland security, food safety, and transportation, among many others^ (NNI 2018a). The responsible development of nanotechnology that ad- dresses the ethical, legal, and societal issues (ELSI) of nanotechnology is one of the NNI’s four objectives, understood to advance the other, i.e., research, commer- cialization, worker education, and public engagement. The way ELSI is addressed is assumed to determine

public trust and the future of innovation driven by nanotechnology (NNI 2018b).

The NNI has served as a role model for other countries aspiring to compete in cutting-edge nanotechnology devel- opment. The responsible development of technology is currently a widely accepted ideal in European Union (EU) research and innovation policies (Coenen 2016). It is generally accepted by scientists, policymakers, regula- tors, and industry that issues concerning environmental impact, health, and safety should be addressed responsibly, ensuring that any new technology benefits society. ELSI has therefore become an important consideration in inno- vation (Coenen 2016). According to this ideal of technol- ogy innovation, the societal need for technology, technol- ogy regulation, and risk management and safety, as well as ethical implications must be thoroughly addressed (Pidgeon et al. 2011: 1696).

The ideal of the responsible development of nanotech- nology implies sensitivity to public perceptions and public trust at an early stage of technology development (Breggin and Carothers 2006). Responsible technology develop- ment is further understood to have the capacity to counter- act failure due to public lack of acceptance of, or opposi- tion to, new technology. Already at an early stage of innovation, US scientists and policymakers worried that the public might turn against nanotechnology (Friedman and Egolf 2005). This is what happened in Europe with genetically modified organisms (GMOs): concern over risk and the lack of trust in science, experts, and regulators were factors that turned the public against the technology as such, the industry, and the products (Wynne 2001). For history not to repeat itself in the form of public distrust of regulatory agencies and scientific experts, consumer boy- cotts of products and companies, citizen pressure on policymakers and regulators, and amplification of risks in the media, foresight and sensitivity to public concern have been recurrent mantras regarding the development of nanotechnology (Sylvester et al. 2009). It has been argued that developers and industry, as well as policymakers and regulators, must be aware of possible public concerns and of the societal dynamics of media and interest groups before they manifest as protests and social movements (David and Thompson 2011).

Upstream engagement in nanotechnology, i.e., early public involvement in the processes of technology de- velopment and innovation, as well as the public provi- sion of relevant and correct information regarding nano- technology, has been envisaged as the road forward (Pidgeon et al. 2017; Rogers-Hayden et al. 2007).

Social scientists have argued that technology should be democratically governed, which calls for Breflexive^ learning processes to develop Bscientific citizenship,^ reflexive governance, and citizen capacity in science (Miah 2017; Pidgeon and Rogers-Hayden 2007: 203). Communication with the public is generally agreed to be necessary for upstream engagement (Priest 2012), un- derstood as part and parcel of the social regulation of nanotechnology (Pidgeon et al. 2017; Priest 2009: 761).

The responsible development of nanotechnology to safeguard the environment, human health, and safety, and to ensure that the new technology benefits society, is understood to require citizen involvement, dialog, and participation. If we look more closely into the literature on the Bcommunication of nanotechnology to the public,^ several broad communicative goals can be identified (Delgado et al. 2011). Pidgeon and Rogers- Hayden (2007: 192) suggested three arguments for pub- lic engagement. The normative argument postulates that dialog is a good thing in itself: it is part of democracy and allows room for public values and attitudes in decision-making. The instrumental argument proposes that dialog with the public increases the legitimacy of decisions and enhances trust. The substantive argument claims that dialog creates better decisions and outcomes. The normative objectives of public inclusion and delib- eration imply broad consultation with stakeholders and the public as well as foresight and reflexivity concerning ethical and legal issues. From this normative position, dialog and public participation are essential values re- lated to innovation, and all these activities rely on infor- mation exchange and the understanding of messages.

Since the mid-1990s when the field emerged, consid- erable social science research into nanotechnology has been published. Policymakers have understood social science to be essential in grasping the dynamics of public attitudes and perceptions and in forming a basis for developing effective tools for gaining public accep- tance of nanotechnology innovation (Ebbesen 2008). Social science research on nanotechnology is multidis- ciplinary, including sociology, psychology, political sci- ence, social anthropology, science and technology stud- ies, and media and communication studies. The accu- mulated research has provided many insights into how nanotechnology is perceived by the public, how it is represented by the media, how media information af- fects public perceptions, and how policy is formed and developed. Many studies have been conducted in the US, the EU, and elsewhere (for overviews of the field,

see Duncan 2011; Kahan 2009; Priest 2012; Ronteltap et al. 2011; Satterfield et al. 2009; Siegrist 2010).

This paper aims to present an overview of the re- search literature on the communication of nanotechnol- ogy to the public between 2002 and 2018. We will systematically identify the problems defined and solu- tions suggested in this research. We contribute by pro- viding an extensive overview of the communication of nanotechnology to the public. By adopting a holistic critical and constructivist approach, this exercise pro- vides a stepping stone to further research and policy work on what socially Bresponsible^ nanotechnology innovation and development might mean and how it might be implemented. The study also contributes to the general discussion of science communication concerning new technology.

Method, research questions, and analytical framework

This paper presents a literature review of published peer-reviewed papers (listed in the references) that ad- dress the topic of the communication of nanotechnology to the public. The papers were identified through a search in the Scopus publication database conducted in February 2018 and through ongoing searches in Google Scholar. The search terms have been Bnano^ in conjunc- tion with Bcommunication,^ Bpublic,^ Bparticipation,^ Bengagement,^ and Bdialog^ to appear in title, abstract, keywords, or main body of text. Altogether, 62 different published journal articles were identified. All 62 papers meeting the search criteria were included in the sample. The oldest study was published in 2002 and the latest in 2018. Some papers explicitly address nanotechnology communication and have Bcommunication^ among their keywords, whereas in others, the presence of the topic is less explicit. Many of the papers address com- munication issues in their discussion sections, where the implications of research findings for practice, regula- tion, or policy are considered. The papers were pub- lished in a broad range of multidisciplinary journals, though four dominate the sample (in order of frequen- cy): Journal of Nanoparticle Research, Risk Analysis: An International Journal, Public Understanding of Science, and Nanoethics. The literature review is not claimed to be exhaustive, but the sample presents a broad range of published research papers giving ample

insight into what scholars discuss when addressing the communication of nanotechnology to the public.

The analysis was inspired by Carol Bacchi’s (1999, 2012) approach to policy analysis. Her analytical and theoretical framework sees policy embedded in a dis- cursive construct that, implicitly or explicitly, estab- lishes problems in need of policy intervention via man- agement and mitigation. From this perspective, problematizations that underlie policy are understood as often taken for granted: they are accepted as Btruths^ beyond questioning (Bacchi 2012). The BWhat is a problem?^ approach allows for the systematic decon- struction and scrutiny of the underlying assumptions of policy problems. The analysis brings these assumptions into the open, enabling a critical approach to policy that can be applied both theoretically and in practical policy work.

According to Bacchi (1999), all problems with policy implications have a generic structure: something is iden- tified as a problem for some reason, and then is isolated, defined, and characterized with regard to its causes and consequences. Defining the problem entails choosing certain elements, characteristics, and causal explana- tions while excluding others. Some elements are foregrounded while others are backgrounded. Since the problem definition and its characterization include causal assumptions about how the problem came into existence, the problem definition paves the way for solutions. Problem definitions and solutions are concep- tually related since solutions are often logically and rationally contained in the problem framing (Lancaster and Ritter 2014). However, in policy work, this is not always the case: problems and solutions can be decoupled without any logical relationship between the two. The identification of a solution may also sometimes preclude the definition of a problem.

The research questions addressed to the literature were developed from the BWhat is a problem?^ ap- proach to policy analysis. The questions answer to the overall aim of providing a systematic and critical anal- ysis of the social science research field of nanotechnol- ogy and public communication. Each article in the sam- ple of 62 papers was read and analyzed with regard to the following questions:

1. How is the problem of the Bcommunication of nanotechnology to the public^ conceptualized, characterized, and explained?

J Nanopart Res (2019) 21: 86 Page 3 of 21 86

2. What solutions are offered to the problem of the Bcommunication of nanotechnology to the public^?

3. What is the relationship between the constructions of problems and of solutions concerning the Bcommunication of nanotechnology to the public^?

The relationship between problem and solution was not analyzed at the level of the individual paper. Far from all papers did provide answers to all three ques- tions. The analysis of the individual papers adds up to a meta-analysis of the material.

The remainder of the paper is organized into the following parts: (1) BBackground: what do we know about public understanding of nanotechnology?^ sum- marizes the main findings regarding public attitudes and perceptions necessary to understand how the problem of nanotechnology communication is discussed; (2) BThe problem of communicating nanotechnology to the public^ addresses problems and obstacles identified in the reviewed literature (this section explicitly addresses communication problems, categorizing them so that the problems can be juxtaposed to the proposed solutions in the next section); (3) BSolutions for the communication of nanotechnology to the public^ offers solutions and recommendations identified in the reviewed literature for the successful communication of nanotechnology; (4) BDiscussion^ treats these findings in relation to the research field; and (5) BConclusions^ wraps up the review and suggests ways forward.

Background: what do we know about public understanding of nanotechnology?

This section summarizes social science findings essen- tial to communicating nanotechnology to the public. In this section, the lessons from previous research are divided into the following themes: (i) public knowledge and attitudes and (ii) factors explaining public attitudes. The reviewed studies were carried out in different coun- tries using different methodologies; while most used surveys and quantitative analysis, others relied on qual- itative methods, such as interviews or focus groups. There are differences in theoretical and analytical frame- work for the studies, and their research designs differ, including case studies, experimental, cross-sectional, and even longitudinal research designs. The results are therefore not immediately comparable (Ronteltap et al. 2011). Our aim with the review was not to evaluate or

discuss why there are differences between studies. Differences in findings can be explained by a number of factors: theoretical assumptions, hypothesis, and re- search design, of data collection and analysis, concep- tual differences (Ronteltap et al. 2011), for example, in how trust is defined and operationalized. Sample char- acteristics also differ a lot. Studies are done on public understanding in different countries, with different reg- ulatory frameworks, and with considerable institutional and cultural differences. These differences also explain diverging findings. Our objective was to identify com- mon main findings regarding public understanding of nanotechnology, since such findings serve as a reference point for formulations of problems and solutions in the investigated sample of papers.

Public knowledge, attitude, interest, and engagement

Many studies have noted that the public lacks knowl- edge of nanotechnology and is unfamiliar with its basic concepts and principles (Castellini et al. 2007; Delgado et al. 2011; Larsson and Boholm 2018; Lin et al. 2013; Macoubrie 2006; Retzbach et al. 2011; Vandermoere et al. 2010). Although there are some national varia- tions, studies in a number of countries confirm this result. One of the first studies of public attitudes toward nanotechnology (Bainbridge 2002) found that the public had a high level of enthusiasm for the benefits of nano- technology and little concern over risks, and later stud- ies have confirmed this result, demonstrating that nano- technology is perceived by the public as beneficial and not associated with risk (Cobb and Macoubrie 2004; Duncan 2011). Other studies have found that a consid- erable portion of the public is indifferent toward nano- technology (Vandermoere et al. 2010). Another often- noted finding is that the public is not homogeneous (Kim et al. 2014: 967), but consists of many groups and segments with different outlooks, values, and ap- proaches to new technology (Cormick and Hunter 2014; Duncan 2011).

Nanotechnology is generally not an issue that spurs public engagement. Only a minority of citizens takes an active interest in nanotechnology and how it should be governed in society (Priest et al. 2011: 1731). When they are concerned, members of the public are worried about the societal implications of nanotechnology use, its environmental effects (Conti et al. 2011), and wheth- er its benefits will be fairly distributed (McComas and Besley 2011). There are some concerns about how

nanotechnology products might affect society in the future, as well as whether or not nanotechnology will contribute to social and environmental sustainability (Pidgeon and Rogers-Hayden 2007: 204–5). In general, the public does not have stable preformed attitudes on the subject of nanotechnology; rather, their attitudes are prone to fluctuate depending on how the media frames nanotechnology, current societal discussions of emerg- ing applications, and their understanding of the benefits, risks, and possible ethical concerns (Satterfield et al. 2009, 2012).

A growing number of studies addresses public attitudes toward various applications of nanotechnology. Risks and benefits are assessed differently depending on the area of application (Pidgeon et al. 2009; Siegrist 2010). That attitudes differ a lot depending on the area of application is clear from many studies (Cacciatore et al. 2011; Cormick 2009; Gupta et al. 2012, 2015; Larsson and Boholm 2018; Pidgeon et al. 2009; Siegrist et al. 2007). For example, people are more favorable toward nanotech- nology applications to remedy water quality, nanotechnol- ogy developments in medicine, and nanotechnology ad- dressing problems in developing countries (Macoubrie 2006: 237). Applications such as cosmetics, on the other hand, are regarded as poorly justified and are generally not approved (Larsson and Boholm 2018; Macoubrie 2006: 236). The public has been found to be skeptical or doubtful toward nanotechnology in the food sector (Bostrom and Löfstedt 2010: 1658; Duncan 2011; Siegrist et al. 2007; Vandermoere et al. 2011).

Several studies focus on public views of the labeling of nanoproducts, which is understood to be an important regulatory tool to manage consumer products containing nanomaterials (Siegrist 2010). Labeling is therefore ex- pected to have an important role in risk communication in the field of nanotechnology (Brown and Kuzma 2013). The public is favorable toward the labeling of nanotechnology used in food. They want labeling for all types of food and are also willing to pay for this, since they believe that labeling facilitates informed decisions related to risk management. Consumers also believe that they have a right to be informed (Brown and Kuzma 2013; Yue et al. 2015).

Factors explaining public attitudes toward and perception of nanotechnology

Many studies have explored the underlying causes of public attitudes toward and perceptions of nanotechnology,

demonstrating that many interacting explanatory variables are involved (Pillai and Bezbaruah 2017). In a meta- analysis of the perceived risk of nanotechnologies, Satterfield et al. (2009) concluded that public perception is influenced by a considerable number of variables, such as framing effects, media exposure, trust in regulation, popular understanding of toxicity, attitudes toward envi- ronmental risks, the perceived naturalness of nanotechnol- ogy, psychometric variables, cultural bias, and religiosity, as well as income and education. In a review of public perception studies of nanotechnology, Siegrist (2010) iden- tified values, trust, and worldview as key explanatory factors shaping views of nanotechnology.

Trust in and respect for science have been shown to be particularly important as an explanation for public attitudes toward nanotechnology (Ho et al. 2010). Many studies suggest that public opinion on nanotechnology is guided by general attitudes toward science and tech- nology, and that broad ideas about the value and use of technology in society guide the formation of attitudes toward nanotechnology (Priest 2009; Priest et al. 2011: 1721). Very few people have personal experience of and familiarity with nanotechnology, an advanced broad transdisciplinary natural science field that is difficult for non-specialists to comprehend. Therefore, it makes sense that deference to scientific authority (Ho et al. 2010), interest and trust in science, and a general belief that scientific knowledge is beneficial all influence atti- tudes toward nanotechnology (Retzbach et al. 2011).

Another dimension attracting interest in several stud- ies is the relationship between support of nanotechnol- ogy and knowledge of nanotechnology. Knowledge of nanotechnology generally increases acceptance, but on- ly slightly (Priest 2009: 763; Siegrist 2010: 840). When people who state that they know little are exposed to information about nanotechnology, they do not automat- ically become more supportive (Anderson et al. 2014: 376). Why, then, is knowledge a weak predictor of attitudes toward risk when knowledge generally makes the public more confident in new technology? It has been argued that nanotechnology actualizes many ethi- cal issues and dilemmas that do not go away or diminish with increasing knowledge of the technology (Pidgeon et al. 2011: 1697). Nanotechnology is also ambiguous due to its many areas of application, huge complexity, and broad scope of use (Renn and Roco 2006).

Values predict attitudes toward nanotechnology (Siegrist 2010). Religious belief has been shown to be negatively correlated with support for nanotechnology

J Nanopart Res (2019) 21: 86 Page 5 of 21 86

(Ho et al. 2010). In another study, religiosity was found to be negatively related to the perceived benefits of nanotechnology (Cacciatore et al. 2011: 393). Other studies, however, do not find religiosity and ideology to be related to the perceived risk of nanotechnology (Anderson et al. 2014: 383). While risk perception has been shown to be gendered for other risk issues (Finucane et al. 2000), research on public attitudes to- ward nanotechnology has mixed findings. Some studies provide evidence that gender to some extent explains attitudes toward, or acceptance of, nanotechnology (Bainbridge 2002: 569; Satterfield et al. 2009: 756), while other studies find no gender effects (Macoubrie 2006: 236).

Studies have shown that public attitudes toward nanotechnology are affected more strongly by informa- tion on risks than on benefits (Satterfield et al. 2012: 257). In some studies, perceptions of the risks and benefits of nanotechnology seem to be related, with higher perceived risks reducing the perceived benefits (Cacciatore et al. 2011: 396). Attitudes toward nano- technology are unstable and can change rapidly depend- ing on new information and how it is presented (Satterfield et al. 2012). Due to the great uncertainty regarding nanotechnology and its potential implications, public attitudes and perceptions are more unstable than they are regarding other more traditional technological risk issues (e.g., chemical risks, radiation, nuclear pow- er, and nuclear waste). One interesting finding is that women have less fixed and stable attitudes toward nanotechnology than do men, which might indicate that gender has higher explanatory power for new and less well-known technologies (Satterfield et al. 2012: 257).

Another factor influencing public opinion is media representations. It is generally agreed in the literature on public perceptions of nanotechnology that the mass media constitute a key factor influencing these attitudes (Scheufele and Lewenstein 2005). It was argued early on in the nanotechnology debate that the public often forms opinions on complex topics of which they have little knowledge and for which they lack relevant infor- mation based on the material provided by the mass media (Scheufele and Lewenstein 2005). How informa- tion is framed therefore influences risk perceptions of nanotechnology, so that risks are perceived differently depending on the social context of the information pre- sented (Schütz and Wiedemann 2008: 377). Risk per- ception is influenced by what information is provided

and opinions also change depending on information (Smith et al. 2008).

Studies have demonstrated that media use correlates positively with nanotechnology support (Ho et al. 2010) and that attention to science news correlates with sup- port for nanotechnology (Cacciatore et al. 2011: 393). The media generally emphasize benefits over risks when reporting on nanotechnology (Anderson et al. 2009; Fitzgerald and Rubin 2010; Lewenstein et al. 2005; Kjølberg 2009; Metag and Marcinkowski 2014), al- though some studies note ambiguous representations and frequent associations with risk (Anderson et al. 2005, 2009; Boholm and Boholm 2012; Friedman and Egolf 2011; Laing 2005; Weaver et al. 2009). However, exposure to information does not have a uniformly positive effect on attitudes toward nanotechnology (Ho et al. 2010: 2711). The public perceives scientific un- certainty expressed in the media differently depending on their level of trust in and deference to science author- ity (Binder et al. 2016). Consequently, representations of science in the media are not necessarily directly linked to public risk perception of new technologies (Binder et al. 2016).

The problem of communicating nanotechnology to the public

That communication with the public on nanotechnology is a delicate matter has been an underlying assumption in the field since its inception. Several challenges for the public communication of nanotechnology have been identified, problems relating to some of the issues discussed above. In this section, we dissect identified problems explicitly noted as challenges in communicat- ing nanotechnology to the public. These problems can be sorted according to basic problem definitions de- pending on how the sources of the problems are identi- fied. Analytically, three main problem themes are dis- tinguished: the public, societal organizations, and nano- technology itself.

The public is a problem

The reviewed literature presents the public as a problem for the communication of nanotechnology in ways that can be categorized into three themes: (i) deficits (i.e., lack of knowledge, interest, and engagement), (ii)

86 Page 6 of 21 J Nanopart Res (2019) 21: 86

heterogeneity, and (iii) attitudes influenced by values and emotions.

(i) Deficits (lack of knowledge, interest, and engage- ment)

Lack of knowledge and engagement among the public is understood as a problem for nanotechnol- ogy communication because it might make infor- mation difficult for the public to comprehend, in turn making it difficult to interest the public in the information provided. As discussed in the section on background, regarding nanotechnology, the public arguably has poor knowledge, is unfamiliar with the technology, harbors misconceptions, and has difficulties understanding central concepts (Castellini et al. 2007: 187; Duncan 2011; Macnaghten 2010: 24; Pidgeon and Rogers- Hayden 2007; Schütz and Wiedemann 2008; Simons et al. 2009: 1596). They also lack engage- ment and interest (Petersen et al. 2007), making it difficult to reach out or involve the public in delib- erative approaches.

(ii) The public is heterogeneous A heterogeneous public constitutes a problem for

nanotechnology communication because the level of knowledge and understanding will differ between subpopulations in society, making it difficult to develop communication strategies. As discussed in the above BBackground: what do we know about public understanding of nanotechnology^ section, the public is indeed heterogeneous and diverse (Duncan 2011: 685; Kim et al. 2014), and research has demonstrated that there are many different po- sitions for or against nanotechnology for many dif- ferent reasons (Priest 2006). The public is segment- ed into sets of beliefs and worldviews and has different attitudes accordingly (Cormick and Hunter 2014). As discussed in the BBackground: what do we know about public understanding of nanotechnology^ section, factors such as religiosity and gender affect perception and might have impli- cations for how information is understood; more- over, cultural cognition and group values influence how people interpret nanotechnology-related infor- mation (Kahan 2010; Kahan et al. 2009).

(iii) The public relies on values and emotions Values, beliefs, and emotions are understood to

influence attitudes toward nanotechnology (Bostrom and Löfstedt 2010; Cormick and

Hunter 2014). The role of values and emotions is identified as a problem theme, since it makes it difficult to foresee how information will be under- stood when attitudes are formed by values, feel- ings, hopes, and expectations rather than on fac- tual knowledge (Simons et al. 2009: 1596). People may not believe in information and might reject information that is not consistent with their values and emotions (Simons et al. 2009: 1596).

Societal institutions are a problem

Another problem associated with communicating nano- technology to the public is that societal institutions are understood as obstacles to successful communication. Societal institutions are seen as a problem for the following reasons: (i) mass media influence attitudes; (ii) mass media provide a fragmented picture of nanotechnology; (iii) nanotechnology regulation is fragmented; and (iv) there is lack of agreement on definitions and concepts.

(i) Mass media influence public attitudes That mass media influence public attitudes is

considered a problem for science communication because it skews public opinion and makes proper science communication difficult. Mass media are understood to influence public attitudes (Binder et al. 2016: 832); how media frame nanotechnology and the lack of reporting are understood to create a problem for science communication. There is a limited discussion of nanotechnology in the media and, when there is, risk is attenuated, which con- tributes to a lack of public interest and engagement (Pidgeon and Rogers-Hayden 2007: 195; Priest 2009: 759).

(ii) Mass media representations are fragmented and ambiguous

The media are understood to offer a fragmented and ambiguous picture of nanotechnology, not providing the public with adequate tools to make informed decisions. This scattered picture, ambi- guity, and uncertainty in the news media arguably might pave the way for fear, contributing to public resistance to nanotechnology (Allan et al. 2010: 42).

(iii) Policy and regulation are fragmented Regulatory uncertainty and fragmentation argu-

ably make it difficult for the public to understand

J Nanopart Res (2019) 21: 86 Page 7 of 21 86

nanotechnology (Laux et al. 2018: 124), and conse- quently more difficult to communicate about nano- technology to the public (Priest 2009: 764). This argument relates to the contemporary regulatory situation with its patchwork of nano-specific and non-nano-specific laws and regulations. Within the EU, there is the regulation Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH), the EU Cosmetics Directive, and the European Food Safety Authority (EFSA), which requires food labeling for nanomaterials (EC 2013). There are regulatory inconsistencies regard- ing communication, since different legislations make different demands: sometimes warning labels, some- times declarations of content, and sometimes public hearings are required in environmental impact as- sessment regulation (Priest 2009: 760).

(iv) Lack of consensus on definitions of concepts A lack of standardized definitions and concepts

among the involved actors is also understood as a problem when communicating nanotechnology to the public. It has been argued that no standardized framework is in place for categorizing nanotech- nology and nanomaterials (Bostrom and Löfstedt 2010: 1652–3). Definitions of nanomaterials are based on different criteria depending on the pur- pose, varying among organizational, industry, reg- ulatory, and research actors (Laux et al. 2018: 122–3). There is a broad range of definitions of nanomaterial and nanoparticle, and there are dis- agreements on what type of definition is the most suitable (Boholm 2016; Boholm and Arvidsson 2016). The Black of a clear and shared understand- ing of key terms^ is considered a problem for science and regulation, since it allows ambiguity and vagueness as well as conflicting messages (Boholm and Arvidsson 2016: 38).

Nanotechnology itself is a problem

It has been argued that the qualities (or lack thereof) associated with the physical and material properties of nanotechnology create challenges for communication for the following reasons: (i) these qualities give rise to low dread risk; (ii) they concern matter that is difficult to describe and visualize; (iii) there are many diverse ap- plications and areas of use; and (iv) they are character- ized by epistemic uncertainty.

(i) Absence of dread risk Due to its material features, nanotechnology is

not perceived as a high-consequence, low- probability risk, associated with involuntariness, dread, and lack of control (Renn and Benighaus 2013: 305–6), and it therefore fits poorly into tra- ditional risk communication frameworks. Dread risk is a concept from psychometric studies of risk perception and pertains to risks perceived as uncon- trollable, global, and catastrophic; having fatal con- sequences; inequitable; posing a high risk to future generations; not easily reduced; and increasing and involuntary (Slovic 1987: 282). Risk issues associ- ated with the highest dread factor in early psycho- metric research were nuclear war, nuclear weapons, and nuclear reactor accidents (Slovic 1987). Nanotechnology scores low on the dread risk factor and is therefore considered a problem for risk com- munication due to an inability to attract necessary public attention and to communicate through rec- ognizable risk scenarios (Renn and Benighaus 2013).

(ii) Beyond perception Nanomaterials exist in a size range invisible to

the naked eye and are not easily described to laypeople. It is therefore argued that, in the eyes of the public, nanotechnology is distant, unfamil- iar, and intangible (Castellini et al. 2007: 187; Macnaghten 2010: 23; Pidgeon et al. 2011: 1695; Priest 2012: 22–3; Simons et al. 2009). Nanotechnology also arguably has uncanny asso- ciations, since it deals with matter that is Bunbelievably small^ and therefore Butterly be- yond human action, perception and control^ (Macnaghten 2010: 24–5). Communicating with the public about uncanny matter beyond percep- tion is therefore understood to be challenging.

(iii) Applications are diverse The diversity of nanotechnology applications

is understood to create a problem for nanotech- nology communication. Nanotechnology includes many diverse areas, heterogeneous substances, techniques, applications, industry branches, and risk issues. Public acceptance also differs between particular applications, qualities, and potential hazards (Duncan 2011; Macnaghten 2010: 24; Pidgeon and Rogers-Hayden 2007: 197; Pidgeon et al. 2011: 1695). As noted in the above BBackground: what do we know about public

86 Page 8 of 21 J Nanopart Res (2019) 21: 86

understanding of nanotechnology^ section, public acceptance of nanotechnology depends on its ap- plication (Berube et al. 2011; Simons et al. 2009), and the perceived risk and benefit profiles of different applications differ greatly.

(iv) Epistemic uncertainty Nanotechnology is surrounded by considerable

uncertainty regarding its nature, benefits, environ- mental risks, human health effects, and safety (Berube et al. 2011: 3097; Grieger et al. 2009). Uncertainty is arguably due to both the complex- ity of nanomaterials as such and to their future implications and consequences (Subramanian et al. 2014). Consequently, many uncertain param- eters must be communicated in policy and regula- tory work on nanotechnology (Williams et al. 2010). It is argued that communicating with the public about uncertain hopes and fears is much more difficult than is communicating established and known facts (Shatkin et al. 2010). For exam- ple, the public wants to know if there actually are nanoparticles in their food and, if so, whether or not this is a health risk; such questions pose a communication problem when science cannot provide clear-cut answers (Bostrom and Löfstedt 2010: 1658).

Solutions for the communication of nanotechnology to the public

In what follows, we will look more closely at specific problem solutions found in the reviewed literature and discuss to what extent they correspond to the problems identified and presented above.

Solutions if the public is seen as the problem.

As we have seen, the public is construed as a problem due to: (i) deficits (i.e., lack of knowledge, interest, trust, and engagement), (ii) heterogeneity, and (iii) attitudes influenced by values and emotions. Solutions involving the public are suggested in the following areas: (i) public education, (ii) academic research on public attitudes/ understanding, (iii) targeted communication, (iv) dialog and participation, and (v) trust and transparency build- ing. The first suggested solution (i) directly addresses the problem of the public knowledge deficit, while the

next two (ii) and (iii) suggest that communication must develop from the current state of affairs and that it can be improved through better knowledge of the target audi- ence; therefore, the first three solutions correspond to defined problems, although indirectly. The solution themes of dialog and participation (iv) and trust and transparency building (v), however, have no clear cor- respondence to any problem formulations. No problem constructions explicitly point to lack of dialog and par- ticipation or lack of trust and transparency as such. These solutions appear to be generally assumed to be good ways to move forward when it comes to commu- nicating nanotechnology to the public. These solutions can be understood as legacies from the upstream en- gagement literature in the field of the public understand- ing of science and from parts of the risk communication literature that emphasize trust and transparency as key parameters of effective risk communication (Priest 2012: 81). This matter will be addressed more thorough- ly in the BDiscussion^ section.

(i) Educate the public From the conception that the public has a low

level of knowledge, making communication prob- lematic, it has been argued that education must be part of any successful communication strategy. People’s knowledge and capacity for critical rea- soning must be improved (Wiedemann et al. 2011: 1781). Gardner et al. (2010) suggested that educa- tional programs to improve Brisk literacy^ in the public should be developed (p. 1965); they recom- mended that risk should be introduced as a topic in science education, so that students can learn to employ tools to Bcritically construct well-formed attitudes and perceptions regarding complex topics^ (p. 1965). Risk literacy applied to nanotech- nology, it is argued, should engender the under- standing that nanotechnology is heterogeneous and includes many applications that can have spe- cific controversial aspects.

It is suggested that education might be accom- plished through the development and use of Bevidence maps.^ Evidence maps consist of sys- tematic characterizations and presentations of argu- ments in a risk debate, and when used to commu- nicate risk assessments, they stimulate a scientific and logical way of reasoning about particular risk issues (Wiedemann et al. 2011). Evidence maps help present complex information in a coherent

J Nanopart Res (2019) 21: 86 Page 9 of 21 86

and pedagogical way. Their use arguably has the potential to resolve conflicts over risk issues, nar- ratives, or arguments in a debate by characterizing and presenting arguments in a systematic way. This pedagogical and communicative tool is intended to help stakeholders and decision makers’ structure information in ways that are more easily accessible to the public.

However, other voices warn of an overreliance on public education to overcome the difficulty of communicating nanotechnology to the public. According to Kim et al. (2014: 967), a communi- cation strategy that has as its main goal educating the public by providing accurate information can- not be expected to create consensus on a risk issue or to lower risk perceptions. This is because attitudes toward nanotechnology depend on values, beliefs, and worldviews rather than on facts. Values are stable and resilient to new information or scientific facts, because factual information provided might not align with conceptual frames among members of the pub- lic.

One aspect of communicating nanotechnol- ogy to the public that has received a fair amount of attention in the literature is the labeling of nanotechnology products and nanomaterials. This growing body of literature is extensive and cannot be reviewed here due to the limited scope of this paper. However, we should note that labeling is understood as an important risk communication strategy for nanotechnology (Siegrist 2010: 843). It is also argued that more research is needed on how labeling and the information provided on la- bels influence the perception of nanotechnolo- gy products (Siegrist 2010). Brown and Kuzma (2013: 534) suggested that simply pro- viding information on product labels alone will not be a sufficient public communication measure. They argue that education and infor- mation on nanotechnology in addition to label- ing are also important. They furthermore rec- ommend that government agencies actively en- gage in public outreach and education on nanotechnology and point out that consumers need education about how to use information on labels to make informed decisions (Brown and Kuzma 2013). There are also concerns

that mandatory labeling could result in a lack of public support for nanotechnology, since this tool could be understood as signaling that significant risks are indeed involved (Siegrist et al. 2007: 463).

(ii) Academic research on public understanding As a way of improving communication strate-

gies, it has been argued that more research on public understanding is needed in order to learn what influences public opinions. The advocates have identified various knowledge gaps in the academic study of public attitudes toward nano- technology that are relevant to communication. Macoubrie (2006: 222) argued that communica- tion with the public on nanotechnology depends on in-depth knowledge not only of attitudes but also of their underlying drivers, i.e., laypeople’s assumptions and premises. Priest (2009: 765) ar- gued that more knowledge is needed of how dif- ferent communication models work, and of what roles, goals, and objectives they entail. One area where more knowledge is needed that has been identified as particularly relevant to the communi- cation of nanotechnology concerns how the public forms perceptions of benefits. Risk perception is a well-researched area, but the perception of benefits is less so (Satterfield et al. 2012: 257).

It has also been argued that it is important to understand under what circumstances perceptions might change (Satterfield et al. 2012: 257). It has been suggested that the mental models framework (Morgan et al. 2002) would be useful since it focuses on how members of the public cognitively construe risk from assumed causal mechanisms (Bostrom and Löfstedt 2010: 1657). However, others have questioned the relevance of the mental models approach, since nanotechnology has a somewhat different dynamic from those of several other risk issues for which traditional risk commu- nication (and the mental models approach) was developed (Pidgeon and Rogers-Hayden 2007: 203).

Because the media are known to influence pub- lic opinion, it has been argued that we need a better understanding of how the media, including new media, work (Duncan 2011). Attention should be paid to new developments in the media coverage of nanotechnology to enable the Bmonitoring^ of public opinion at different stages of the Bissue–

86 Page 10 of 21 J Nanopart Res (2019) 21: 86

attention cycle^ (Ho et al. 2010: 2711). It has been argued that more knowledge is needed of how changes in media coverage (which might be sud- den and drastic) affect public perception (Scheufele and Lewenstein 2005: 665).

(iii) Develop targeted audience-specific communica- tion

When considering solutions, the focus is on targeted communication based on an understand- ing that the public is fragmented and that different audiences respond to information in different ways. Targeted nanotechnology communication is tailored to the understandings, values, needs, and knowledge of particular groups, with the aim of helping them understand nanotechnology and gain the tools needed to make well-balanced de- cisions for themselves (Duncan 2011; Ho et al. 2010: 2710–1; Pillai and Bezbaruah 2017: 41; Yue et al. 2015). Targeted communication is un- derstood by its advocates as helping empower the public by providing information, so that members of the public might become informed despite their knowledge limitations (Simons et al. 2009: 1596). A key message in this line of thought is that the public cannot be treated as a single homogeneous mass expected to respond uniformly to science communication.

The core message from this perspective is that the public consists of various audiences differing in ethnicity, race, language, religion, and so on. Specific audiences should therefore be identified and addressed separately as distinct Binterpretative communities,^ as there is no such thing as Bone size fits all^ in communication (Priest 2009: 764). In the same vein, Kahan (2010: 297) argued that information about nanotechnology should be pre- sented so that it is Bagreeable to culturally diverse groups.^ Kim et al. (2014: 978) recommended that risks and benefits be addressed in special communication campaigns tailored to the audi- ences’ particular cognitive styles. For people who process information systematically, more information should be provided, and for those who rely on heuristics, communication should take account of values (Kim et al. 2014: 978). Following this line of reasoning, Ho et al. (2010: 2710–1) suggested forming partnerships with religious institutions to reach religious segments of the public.

(iv) Develop dialog and participation Another solution is to develop initiatives and

strategies for involving the public in dialog and policy processes (Sodano et al. 2016: 725; Vandermoere et al. 2011: 204). Priest (2009) ar- gued that opportunities should be made for public discussion and education and for the public to give opinion feedback to policymakers. A need has been identified for Boutreach efforts on meaning- ful public engagement and dialogue that builds relationships among risk managers and the public, rather than one-sided efforts designed to educate and inform the public^ (McComas and Besley 2011: 1758–9).

These deliberative approaches, it is argued, should involve scientists, engineers, and laypeo- ple (López-Vázquez et al. 2012: 203) as well as the policy sector (Sodano et al. 2016: 725). Others have argued that the industry must take more responsibility for communication (especially in the case of nanofood). In the nanofood sector, it is recommended that the industry should use trade associations as partners, collaborate with social scientists, and promote public engagement (Duncan 2011). A concrete suggestion is to facil- itate Bgroup talk^ to critically engage with future- oriented techno-scientific politics in which policy- oriented critical social scientists have a distinct role in developing dialog between the public, sci- ence, and policy concerning new technology (Macnaghten 2010: 32). However, it is also argued that public participation must be structured so that Bcultural polarization^ is avoided between differ- ent groups (Kahan 2010: 297).

(v) Build transparency and trust To engage the public, it has been argued that

trust must be established, and that transparency is a good way of doing so. It is assumed that greater trust and transparency will almost automatically increase public acceptance of nanotechnology (Vandermoere et al. 2011: 204). Siegrist (2010: 842) emphasized the need to induce high public trust in government and regulation. It has also been argued that new thinking about how to be proactive and transparent in communication and that estab- lishing new relationships with the public are ways forward toward integrating and commu- nicating research and risk assessment (Shatkin et al. 2010: 1685).

J Nanopart Res (2019) 21: 86 Page 11 of 21 86

To build trust, it has been argued that it is important to consider who should communi- cate nanotechnology information to the public and that already trusted institutions should be involved (Simons et al. 2009: 1596–7). Capon et al. (2015: 11) argued that risk communica- tion is best undertaken by trusted scientists. Ho et al. (2010: 2710) suggested that policymakers should promote and instill trust in scientists and deference to scientific authority among the public, for example, by arranging for Beminent scientists^ to hold seminars. Similarly, Shatkin et al. (2010: 1685) recommended that an independent and trusted Bentity^ should be established for the purpose of managing and im- proving science communication.

Solutions if societal organizations are seen as the problem

We have seen that societal organizations are construed as a problem for the communication of nanotechnology for the following reasons: (i) the mass media influence attitudes; (ii) the mass media provide a fragmented picture of nanotechnology; (iii) policy and regulation are fragmented; and (iv) there is a lack of consensus on definitions and concepts. The proposed solutions to these problems are the following: (i) media manage- ment, (ii) strengthening policy and regulation, and (iii) increasing clarity and consistency in communication. These solutions correspond to the problem construc- tions, by trying to eliminate what are considered obsta- cles in society to the successful communication of nanotechnology.

(i) Media management Managing the media in various ways is a com-

mon suggestion for improving nanotechnology communication from the perspective of the scien- tific community. A practical suggestion for connecting the media more closely to science is that a science media center could be set up to serve as an Bindependent agenda-free organization for evidence-based science^ (Duncan 2011: 688). It has also been argued that risk communication should preferably be in place before any negative events are reported in the news media (Simons et al. 2009: 1596), so those concerned can be prepared to

address any event or public scandal. To achieve stronger public engagement, it has been recom- mended that new media and peer-to-peer commu- nication be utilized (Bostrom and Löfstedt 2010: 1657). Ho et al. (2010: 2711) recommended that public officials should use the mass media to run campaigns, and should sponsor science programs on public broadcasting channels to offer accurate and up-to-date nanotechnology information to the public.

(ii) Strengthening policy and regulation As communication is understood to be hindered

or made more difficult by policy and regulation fragmentation, one solution is regulatory change. Government regulatory bodies, it is argued, must ensure compliance with guidelines in order to ef- fectively manage toxicity and safety, in order to maintain public trust (Ho et al. 2010: 2710). Major public investment in risk research, early warning systems and monitoring, stringent pre-market au- thorization, mandatory labeling, and establishment of a public register of products and producers have also been recommended (Sodano et al. 2016: 725).

(iii) Increase clarity and consistency in communication To improve communication regarding nanotech-

nology, it has been argued that communication must be clear and consistent (Shatkin et al. 2010: 1685). Communication should address terminology issues as well as ensure clarity, consistency, and parsimony in communication (Shatkin et al. 2010: 1686). Boholm and Arvidsson (2016) suggested that the terms nanoparticle and nanomaterials should be de- fined and used consistently, given a particular pur- pose, to serve as the basis for a shared understanding among relevant regulators and parties. Another rec- ommendation is that the Bexact method and phrasing^ of messages must be carefully considered (Smith et al. 2008: 471–2). Reisch et al. (2011: 650) recommended that the Blatest research on the poten- tials and risks of nanoproducts and nanomaterials should be translated into an easily understandable format^ to be disseminated to consumers.

Although there are calls for more clarity in the messages communicated to the public, there is a striking disagreement on how messages should be formulated and what should be emphasized. Some believe that the benefits of nanotechnology should be highlighted in a balanced way to promote public acceptance of nanotechnology (Kim et al. 2014:

86 Page 12 of 21 J Nanopart Res (2019) 21: 86

977). Steenis and Fischer (2016: 1262) suggested that communicating the personal benefits of nano- technology in food will be a key element in building acceptance. They also suggested that more attention should be paid to identifying and communicating the concrete benefits of nanotechnology to actual con- sumers (Steenis and Fischer 2016: 1264). Sodano et al. (2016: 7249) have generally recommended that policymakers should engage in communication aimed at increasing public acceptance by conveying information about benefits and Burging greater trust in industry and science.^

However, it is also argued that if nanotechnology benefits are overemphasized, the public might have problems accepting nanotechnology if disturbing news about hazards emerges in the future. Risk must therefore be addressed in order to keep the public prepared for negative information (Satterfield et al. 2012: 258). Experts have an important role as com- municators and should Bdemonstrate their willing- ness to speak candidly about potential risks^ (McComas and Besley 2011: 1759). Sodano et al. (2016: 725) recommended against policymakers communicating policies with the sole aim of attempting to increase public acceptance; they should instead address risks associated with nano- technology. Science-based information that is open and balanced is understood to be an important tool helping the public form well-grounded opinions (Cobb and Macoubrie 2004: 404).

Solution if nanotechnology itself is seen as the problem

As seen above, the physical properties of nanotechnol- ogy (and the associations evoked) have been identified as a problem for communication for several reasons: (i) they give rise to low dread risk; (ii) they concern small and difficult to perceive properties of matter; (iii) they relate to many different applications and areas of use; and (iv) they are associated with epistemic uncertainty. The suggested solution addressing nanotechnology it- self as a problem is to improve our knowledge of nano- technology, a solution intended to reduce the epistemic uncertainty associated with nanotechnology. Problems (i)–(iii), however, although understood as problems for the communication of nanotechnology to the public, lack any suggested solutions.

(i) Improve knowledge of nanotechnology It has been suggested that nanotechnology risk

assessment and lifecycle assessment should be advanced in order to improve the quality and accuracy of risk communication. Laux et al. (2018) proposed that nanomaterials must be char- acterized and understood during different lifecycle stages; they also argued that the risk assessment of nanomaterials must be developed, since knowledge derived from risk assessment is the fundamental content to communicate to the public. Similarly, Pidgeon et al. (2011: 1696) noted a need for more Bsophisticated quantitative studies^ of the risk of nanomaterials in order to improve communication with the general public.

Discussion

This review of the scholarly debate on nanotechnology communication and the public has identified problem definitions as well as solutions for communicating with, and involving, the public. An overview of the field reveals that there is congruence between problem con- structions and solutions for some topics, but not others. There are systematic overlaps, but also some striking decoupling between problem definitions and recom- mended solutions for policy and practice. An overview of problem formulations and solutions is provided in Table 1.

In this section, we will discuss problem definitions and solutions in relation to the research field producing these problem definitions and suggested solutions.

One important reason for the lack of congruence regarding problem formulations and suggested solutions is that there is no consensus as to the goals of commu- nicating nanotechnology to the public. The rationale for such communication stems from underlying normative ideals rather than from a need to address certain identi- fied problems. There is an underlying, deeper identifi- cation and conceptualization of a problem about the role of citizens in society in relation to new technology. This underlying problem formulation addresses the need for communication with citizens about emerging technolo- gy and is part and parcel of the ideals of responsible innovation intimately linked to the development of nanotechnology in the US and the EU.

A normative position often assumed in the literature is that communication on nanotechnology should pro- mote empowerment and reflexivity among the public to Bencourage deeper thought about issues that might oth- erwise be ignored^ (Priest 2009: 762), and that commu- nication should Bempower people to participate in mak- ing decisions that reflect their own values rather than (necessarily) the values of the technology promoters or detractors.^ What is called Bupstream engagement^ in the literature on the public understanding of science strives to promote civil society–science policy dialog in which the public is included in decision-making on technology (Pidgeon and Rogers-Hayden 2007: 192; Pidgeon et al. 2017). Upstream engagement to involve the public is understood to enhance the legitimacy of new technology (Priest 2009: 760).

The normative stance implies that policymakers must try to Bintegrate the public’s views into risk decision making^ (McComas and Besley 2011: 1750). It is rec- ommended that a collaborative problem-solving ap- proach should be used in nanotechnology policy to identify issues of concern among the public (Macoubrie 2006: 222). This perspective on the

communication of nanotechnology is understood to be essential to empower people in decision-making concerning nanotechnology (Simons et al. 2009). It is advocated that this communication with the public should be two-way communication or dialog (Pidgeon and Rogers-Hayden 2007: 193; Priest 2009; Toumey 2013: 226); that openness and transparency about un- certainties should guide the regulation and management of risks (Priest 2009); and that transparency should be seen as crucial to creating public trust (Priest 2009: 760). According to the norms of upstream engagement, solutions emphasize participation, dialog, transpar- ency, and other modes of motivating the public to engage in discussions and decision-making regard- ing nanotechnology.

Another stance is the Bdeficit model^ of the public understanding of nanotechnology (Rogers-Hayden and Pidgeon 2007; Priest 2012: 26). This model identifies elements lacking among the public, elements under- stood to be crucial to communication, such as knowl- edge (the public has poor knowledge), trust (the public mistrusts regulators, policymakers, scientists, and/or the technology), and engagement (the public is not

interested and does not care) (Rogers-Hayden and Pidgeon 2007). If the public is understood to lack proper knowledge of nanotechnology, a main communication goal will be to educate and inform the public. From this perspective, communication should provide information to educate the public about nanotechnology, the under- lying science, and the actual associated risks and bene- fits (Delgado et al. 2011). If communicative actions to address deficits in knowledge (more education) or def- icits in trust (more transparency) are successful, it is assumed that public acceptance of nanotechnology will increase (Ebbesen 2008). There is a certain overlap in the two positions when it comes to building public trust. If the public is understood to lack trust and engagement, a main communicative goal will be to engage through participation and various efforts to create dialog (Rowe and Frewer 2000).

The different problems and solutions identified in the reviewed literature should be understood in relation to different overarching ideas about public upstream en- gagement, and about knowledge and/or trust deficits. These ideas are related to two partly overlapping inter- disciplinary social science research fields: risk commu- nication, which is part of risk research, and science communication, which is part of science and technology studies (Pidgeon and Rogers-Hayden 2007; Priest 2009; Renn and Benighaus 2013). Scholars from the risk communication field tend to focus on providing correct, factual information on risk issues, correcting misunder- standings and false beliefs, influencing and correcting lay mental models of the causes and effects of a risk issue, and raising awareness of scientific knowledge (Shatkin et al. 2010). Scholars from science and tech- nology studies, on the other hand, emphasize more broadly the role of technology in society: how technol- ogy is organized and institutionalized and how actors engage in technology, as well as what power relations, meaning systems, ideological frames, and norms sur- round technology as a social phenomenon (Pidgeon and Rogers-Hayden 2007).

The fundamental challenges acknowledged in both fields are basically the same: how to stimulate debate when the topic is not prominent in society? How to create engagement when the public is not interested? How to disseminate knowledge of an issue that does not engage people? How to create engaged citizens with an interest in science and innovation? How to disseminate knowledge when there is a lack of engagement and interest? (Petersen et al. 2007). The communication of

nanotechnology can be understood as a paradox: there are norms of science participation and the scientification of public knowledge, on one hand, and a lack of public interest and capacity to participate, on the other (Binder et al. 2016: p. 831). The paradox in play is that upstream engagement initiatives even might create an awareness of risk, socially amplifying the perceived risks of nano- technology among the public (Pidgeon et al. 2011: 1696).

The findings of this review of the literature on com- municating nanotechnology to the public support the findings of another literature review on re- search into Bsocietal responses^ to nanotechnology. Ronteltap et al. (2011) reviewed 107 papers pub- lished between 2002 and 2010 with the aim of identifying overarching frameworks and common problem formulations. They found that the field is heterogeneous and fragmented, lacks uniform research problems and problem definitions, and lacks a generally agreed-upon theoretical frame- work as well as consistent concepts and terminology. There was a lack of collaboration between natural and social sciences and it was difficult to compare research and research findings. Ronteltap et al. (2011) also noted a pleth- ora of divergent problem formulations, solutions, and recommendations for practice and policy reflecting the orientations of diverse academic fields, research paradigms, and ways of conducting policy-relevant research. They concluded that the fragmented problem definitions and suggested so- lutions reflected a lack of cross-fertilization be- tween subfields and disciplines. There is a lack of agreement on the research problems, theoretical framework, or even common goals and objectives. Hence, it is difficult to extract viable lessons and policy implications for reflexive innovation in the field.

We have reached similar conclusions regarding the construction of the field of research on nanotechnology and communication with the public. However, we found a broad consensus in the cited literature about a need for communication with and/or involving the public as part of the responsible innovation of nanotechnology. However, there is little agreement on how exactly to achieve this, or even why it is desirable. The reviewed literature presents different problem formulations as well as different solutions to achieve successful communica- tion strategies. The solutions are sometimes decoupled

J Nanopart Res (2019) 21: 86 Page 15 of 21 86

from the problem definitions, and the problem definitions and solutions are sometimes also decoupled from re- search. One important reason for this is the normative stance of public deliberation in relation to the responsible innovation of nanotechnology. A lack of agreement on theories and perspectives creates contradictions in the debate on nanotechnology communication, and different recommendations are based on divergent views of the public, of the effects of interventions, and of the goals of communication.

Conclusions

What lessons can be learned from the almost two-decade- long debate on the communication of nanotechnology to the public? Although the debate is fragmented and is based on conflicting ideals that are difficult to balance, the communication of nanotechnology is nevertheless seen as an important issue in society. Successful science communication is important for establishing trust in science and the scientific community, as well as in other societal organizations, and controversies surrounding nanotechnology might seriously affect trust in society more generally. Communication strategies and goals are important, as communication done the wrong way very well might lead to a backlash, and information intended to soothe the public might instead stir up concern. As Pidgeon et al. (2011) argued, it is paradoxical that up- stream engagement initiatives might activate risk percep- tions and contribute to the social amplification of nano- technology as associated with risk (Pidgeon et al. 2011: 1696). From insights gained from the reviewed literature, we wish to conclude by making some constructive

suggestions for nanotechnology communication. A sum- mary of recommendations is presented in Table 2.

Define objectives of communication We suggest that the reasons why nanotechnology should be communicated to the public be identified and defined. Why is commu- nication about nanomaterials important, and what do we want to achieve through this communication? It is im- portant to be specific and transparent about the general objectives of communication and public involvement, and to define the objectives of specific communication initiatives and of initiatives intended to involve the public in any deliberative approach. By addressing this issue upfront, it is easier to avoid conflicting goals in any communication strategy. Recognizing objectives is an important step in designing and implementing com- munication regimes for nanotechnology, with conse- quences for who should communicate and whom should be targeted.

Utilize previous research in a responsible way When the rationale for communication is defined, it is possible to systematically utilize previous research findings. Although certain fundamental challenges with commu- nicating nanotechnology are not easily resolved, public attitudes and opinions and what might influence them are relatively well researched. Taken together, we actu- ally know quite a lot about public knowledge, public attitudes, what influences public attitudes, and how these attitudes can be expected to change due to differ- ent circumstances. Relevant studies have treated differ- ent groups in society, different countries, and conse- quently different regulatory and societal contexts. Considerable research has also examined media repre- sentations and how media information influences public attitudes and perceptions, research that can be utilized in designing communication strategies.

While recognizing the importance of utilizing previ- ous research on the public understanding of nanotech- nology when designing successful communication strat- egies, we also call for caution in how research is utilized in formulating communication strategies. Individual studies can be used, but analyses of metadata should be employed to draw more general conclusions. General problem formulations and underlying assumptions need to be considered. There is an immanent risk of making recommendations for communication based on individ- ual studies, when the body of literature in fact presents contradictory results. The methodological, theoretical,

2 Utilize previous research in a responsible way: research should be systematically assessed, focus on metadata rather than individual studies

4 Do not aspire for a generic framework for communication: take into account application area, industry sector, regulation, consumer interest, public perception, and acceptability

86 Page 16 of 21 J Nanopart Res (2019) 21: 86

and normative points of departure of the studies, as well as their empirical scope, need to be recognized and critically assessed by asking questions such as: what conclusions can be drawn from the studies? Are the results of a study in one country translatable to another? Can we assume that the identified differences will re- main stable over time?

Recommendations for targeted communication are often stressed in survey studies identifying differences between groups in society, implying that information should be tailored to differences in knowledge and cognitive style between audiences. Recommendations for targeted communication are often a conclusion drawn from the results of individual studies iden- tifying statistically significant differences between two groups (e.g., religious–non-religious, men– women, and well educated–poorly educated). This might seem a reasonable implication of such stud- ies; however, differences between groups are often small even though statistically significant, and sim- ilarities might still be important. Furthermore, dif- ferent studies report different results, for example, with gender differences seeming to matter in some studies, while others find no such differences. Targeted communication might even polarize and compromise the perceived integrity of societal or- ganizations and the scientific community. Tailored messages can be interpreted as conflicting infor- mation or as attempts to manipulate, and as a communication strategy might even cause a back- lash. Therefore, targeted information should be carefully tested and evaluated before being put into practice.

Develop communication to match the context This study has identified several not easily changed problems relating to the communication of nanotechnology: the qualities of nanoparticles, the fragmentation of current regulation, media reporting, a lack of interest and en- gagement among the public, and the fact that public attitudes are influenced by beliefs, values, and emotions rather than by factual knowledge. From a communication perspective, these things are not easily changed, and communication strategies should instead be developed in relation to context. The communication of nanotechnology to the pub- lic cannot rely on changes in regulation, changes in public interest or engagement, or changes in the physical properties of nanomaterials or

nanoparticles. The public cannot be expected to become involved in dialog and communication processes that do not interest them. Some sug- gested solutions involve changing the media rep- resentations. While it might be a good idea for scientists to provide good didactic information for the media, it might not be a good idea to try altering how the media evaluate what news is deemed relevant to communicate or to intervene in the workings of the media and the principles of news evaluation. Criticizing or trying to manipu- late the free press might cause serious backlashes in public trust.

Do not waste effort developing any generic framework for communication While the fragmentation of the field is recognized in the reviewed literature, many of the recommendations assume that the communication of nanotechnology is a uniform, generic problem. There are, however, large differences between nanotechnology applications and areas of use: there are different tech- nologies used for manufacturing, different bulk mate- rials, different industrial sectors, and consequently dif- ferent responsible regulatory bodies. Nanomaterials in- volve a wide range of techniques and materials with very little in common in terms of potential risks and benefits, and there is large variation in public perception depending on the specific uses. The communication of nanotechnology cannot be ad- dressed as a generic problem, as it is context dependent. For this reason, diverse communication strategies might have to be developed for different application areas. Besides being inefficient and difficult to implement, a unified framework for the communication of nanotechnology might very well prompt serious backlashes. For example, by applying mandatory labeling across diverse areas of nanotechnology application, hazards identified in one application area might have seriously neg- ative effects on public perceptions of other completely unrelated products as regards toxicity or potential risk scenarios.

Methods used in Cyber warfare and cyber attacks

Just like other warfare, Cyber warfare is a digital war where computer viruses are sent instead of army and hacking into database with the aim to create damages and destruction. With the increasing use of computer and technology in almost every field obstruction of data can be a bigger war than an actual war. Acquiring sensitive data about a country, business, person or anything that relies in computational functions are in risk if the data is lost which can cause metamorphosis of a certain company that relies hugely on computer. There are diverse methods that various people or nations, for a set of diverse reasons, can damage computers or information network. Cyber-attack is a broad picture of cyber warfare, similar types of methods are used in cyber warfare and cyber-attack. When a nation’s database or the system of one of its branches is attacked for war reasons or for manipulation, the term cyber warfare is used.

There are diverse methods that various people or nations, for a set of diverse reasons, can damage computers or information networks. In a broad picture, espionage is one of the cyber-attacks, espionage in literal meaning refers to the practice of spying. Spying using a computer falls under cyber-attack. Another type is sabotage, sabotage is the act of destroying data. Changing the propaganda digitally is another type of cyber-attack. Disruption of economy is another huge concerned area of cyber-attack.

Malware in commonly known as computer virus. “Malware is a term used to describe malicious software, including spyware, ransomware, viruses, and worms. Malware breaches a network through a vulnerability, typically when a user clicks a dangerous link or email attachment that then installs risky software” [1]. Malware is the most common and the most dangerous type of a cyber-attack. Malware can be of many types and they are sent by hackers intending to block and/or change network keys or settings, damage information from a computer or a network of computers, sabotage and most importantly disable a system.

Denial of service (DoS) and distributed denial of service (DDoS) is, as the name suggests, a type of cyber-attack that denies a user form getting into an online system or database. “A denial-of-service attack floods systems, servers, or networks with traffic to exhaust resources and bandwidth. As a result, the system is unable to fulfill legitimate requests. Attackers can also use multiple compromised devices to launch this attack” [1].

SQL injection is a type of cyber-attack where the attacker uses SQL code to acquire any sort of information from a computer. “A Structured Query Language (SQL) injection occurs when an attacker inserts malicious code into a server that uses SQL and forces the server to reveal information it normally would not. An attacker could carry out a SQL injection simply by submitting malicious code into a vulnerable website search box” [1].

Man-in-the-middle attack is the type of cyber-attack that interrupts or attacks a computational communication. An attacker inserts himself in a conversation between two parties, either personal communication or interaction between a user and an application making it appear like a normal conversation. “Man-in-the-middle (MitM) attacks, also known as eavesdropping attacks, occur when attackers insert themselves into a two-party transaction. Once the attackers interrupt the traffic, they can filter and steal data.

Two common points of entry for MitM attacks:

1. On unsecure public Wi-Fi, attackers can insert themselves between a visitor’s device and the network. Without knowing, the visitor passes all information through the attacker.

2. Once malware has breached a device, an attacker can install software to process all of the victim’s information” [1].

Phishing is the type of attack that is intended in stealing login credentials, credit card information or any other information that is saved in a browser or an application. “Phishing is a cyber-attack that uses disguised email as a weapon. The goal is to trick the email recipient into believing that the message is something they want or need — a request from their bank, for instance, or a note from someone in their company — and to click a link or download an attachment” [2].

There could be a million reasons for a person or group of people to involve themselves in cyber warfare or cyber-attacks. Acquiring information about a country could ruin a country’s prestige and could allow power to the wrong people. As an example, many countries use electronic methods for voting, if a voting system is hacked power of that country can belong to anyone. There could be military reasons for cyber warfare, for two rival nations knowing the next move of your rival can play a vital role in a war situation. If communication system between the military and the government can be hacked that will put a whole country into threat. Manipulation of a country’s database can ruin the information that they have about their citizens. “Offensive cyber operations offer a large variety of cheap and risk-free options to weaken other countries and strengthen their own positions. Considered from a long-term, geostrategic perspective, cyber offensive operations can cripple whole economies, change political views, agitate conflicts within or among states, reduce their military efficiency and equalize the capacities of high-tech nations to that of low-tech nations, and use access to their critical infrastructures to blackmail them” [3].

Military in many countries have a department of cyber security, they recruit people to save and/or attack different nations for military purposes. “Examples of cyberwarfare driven by political motivations can be found worldwide. In 2008, Russia began a cyber-attack on the Georgian government website, which was carried out along with Georgian military operations in South Ossetia. In 2008, Chinese 'nationalist hackers attacked CNN as it reported on Chinese repression on Tibet” [3]. There have been rumors of Russia attacking US presidential election held on 2016. “The Senate Intelligence Committee concluded Thursday that election systems in all 50 states were targeted by Russia in 2016, an effort more far-reaching than previously acknowledged and one largely undetected by the states and federal officials at the time” [4]. “The US Department of Justice has charged 12 Russian intelligence officers with hacking Democratic officials in the 2016 US elections” [5]. Countries attacking other countries digitally is not fresh news. There have been instances where powerful countries have used technological means to attack a rival country. There might be a lot of activities that never made it to the news channels. “Computers and satellites that coordinate other activities are vulnerable components of a system and could lead to the disruption of equipment Compromise of military systems, such as C4ISTAR components that are responsible for orders and communications could lead to their interception or malicious replacement. Power, water, fuel, communications, and transportation infrastructure all may be vulnerable to disruption” [3].
