Modern lie detection techniques have evolved beyond traditional methods like the polygraph. These advancements aim to detect deception by analyzing physiological and psychological responses. Key techniques include:

Polygraph Test: Measures multiple physiological responses, assuming deception triggers distinct physical changes.
Nonverbal Cues: Focuses on body language and facial expressions to identify signs of deceit.
Verbal Cues: Analyzes speech patterns and language use to detect lies.
Methods That Manipulate Statement Production: Techniques that encourage truth-telling or expose inconsistencies in statements.
Psychophysiological Detection: Uses psychological responses along with physiological measures for a more comprehensive assessment of deception.
Despite these advancements, the accuracy and reliability of lie detection methods remain a topic of debate.
