Deception research involves studying the ways in which individuals deceive others, either through lying, manipulating information, or faking emotions. Researchers in this field often explore the motivations behind deception, how people are able to detect deception, and the consequences of being deceived. Additionally, deception research may also examine the effectiveness of various deception-detection techniques, such as verbal cues, nonverbal cues, and cognitive load. Understanding deception is important for fields such as psychology, communication, and law enforcement, as it can help individuals better navigate social interactions and protect themselves from being misled.
