Consistently, research shows that the ability of people to detect lies cannot be considered accurate anymore. The need to accurately detect a lie is critical in identifying criminal offenses and to avoid detaining suspects who are innocent. Various solutions can be put into practice to solve the problem underlying effective techniques for lie detection.

Adopting autonomic indicators is a great solution when dealing with lie detection (National Research Council, 2003). The application of the polygraph technique in psychophysiological detection analyzes while signaling body changes that normally cannot be detected through human observation. One of the advantages of using the polygraph technique is being able to identify criminals easy, as the tools are used in “scaring people straight” thats considered espionage. However, this technique is vulnerable to both psychological and physical countermeasures while suffering from significant errors.

The second solution is observing the body and facial movements. This technique is mostly applied in social conflict situations. Physiology and psychology researchers have shown the association between anxiety portrayed by an individual when lying and the organic response difficult to change or control, such as; sweating, blood pressure, dilated pupils, and changing body temperature (National Research Council, 2003). However, this technique faces the challenge of wrongly accusing individuals who suffer from communication difficulties as they portray similar signs. Also, these body changes are similar to a sick person, one under medication or stress.
