Deceptive Behavior: Effects of Rational Thinking, Narcissism, and Self-Assessed Lie- and Truth Related Abilities

The present study examined how narcissistic features, self-assessed lie- and truth-related abilities, and thinking processing style influence successful lying and convincing truth-telling. To this end, 100 undergraduate students completed the NPI, REI, and LTAAS questionnaires and drew two drawings each. They then presented to a panel of four fellow student judges, 0, 1, or 2 of their drawings together with other pictures, and tried to convince the panel that they had not drawn any of the drawings. Finally, judges reported whether they believed the presenter. Results showed positive correlations between narcissism, self-assessed lying ability, and self-reported rational thinking. Intuitive thinking predicted success in lie detection. The present results enrich our understanding of situational and personal factors involved in intuitive lie detection.
