What makes a good liar? The relationship between cognitive and personality assessments’ and lying ability using traditional and strategic interview approaches

Abstract

<p>Over the past several decades, scholars have sought to better understand and refine the process of detecting deception (see Vrij, 2015). However, considerably less research has focused on identifying the characteristics and abilities of effective liars. The purpose of the present project was to begin to examine individual differences in lying ability and identify skills and traits of more successful liars. Participants in this study lied or told the truth under various conditions and then naïve observers judged the veracity of those statements. Overall, participants did not demonstrate good calibration between confidence in their ability and performance on the task. Additionally, some individual difference measures (e.g., working memory capacity, task switching ability, and Machiavellianism) were found to be related to the ability to lie well while others (e.g., inhibitory control, narcissism, and psychopathy) were not. Additionally, good liars were not affected by new strategic interview approaches (e.g., reverse order recall) as performance during control phases of interviews was related to performance during strategic phases. The relationships between confidence, ability, personality traits, cognitive abilities, and strategic interviewing approaches was examined.</p>
