Despite numerous tools developed to detect lies—such as polygraphs and voice-stress analyzers—most are unreliable. Instead of focusing solely on physiological changes caused by lying, the author advocates for a direct analysis of the language used in deceptive statements.
Lies are often told to present a better self-image, and our subconscious reveals patterns in language when we lie. Key indicators of deception include minimal self-references, negative language, simple explanations, and convoluted sentence structures.
