The current study is the first to investigate whether individual differences in personality are related to improved first impression accuracy when appraising psychopathy in female offenders from thin-slices of information. The study also investigated the types of errors laypeople make when forming these judgments. Sixty-seven undergraduates assessed 22 offenders on their level of psychopathy, violence, likability, and attractiveness. Psychopathy rating accuracy improved as rater extroversion-sociability and agreeableness increased and when neuroticism and lifestyle and antisocial characteristics decreased. These results suggest that traits associated with nonverbal rating accuracy or social functioning may be important in threat detection. Raters also made errors consistent with error management theory, suggesting that laypeople overappraise danger when rating psychopathy.Keywords thin-slices, personality differences, psychopathy, error management theory, first impressions Date received: July 14, 2016; Accepted: September 20, 2016 Despite concerns regarding the accuracy of first impressions, research suggests that judgments based on 30-to 60-s segments of audio/visual information called thin-slices can be more accurate than longer term judgments. Previous research found that laypeople ratings are related to accurate identification of personality (Carney, Colvin, & Hall, 2007;Funder, 2012), deception (Costanzo & Archer, 1989), and violence (Stillman, Maner, & Baumeister, 2010). People may possess these skills because it is an evolutionary advantageous detection mechanism against those perceived as a threat. Bar, Neta, and Linz (2006) argue that being able to quickly and accurately identify personality traits in people we first meet allows us to detect dangerous cues early in an interaction and flee before harm can be inflicted.
Psychopathy and First ImpressionsIt is less clear, however, if this is true of all high-risk individuals, such as psychopaths. Psychopathy is associated with a constellation of features including deceit and manipulation (interpersonal; Facet 1), callousness and a lack of remorse (affective; Facet 2), impulsivity and irresponsibility (lifestyle; Facet 3), and poor behavior control and criminal versatility (antisocial; Facet 4;Hare, 2003). Initially, it would seem that laypeople would have difficulty detecting psychopaths because of their ability to conceal deviance using deceit and superficial charm. Consistent with this theory, Furnham, Daoud, and Swami (2009) found that laypeople had a more difficult time detecting psychopathy from presented vignettes than other mental illnesses, such as depression and schizophrenia.Conversely, growing empirical evidence suggests that psychopathy may be detected from a first impression. Fowler, Lilienfeld, and Patrick (2009) found that student raters were able to correctly and reliably perceive overall, Factor 1 (interpersonal and affective facets) and Factor 2 (lifestyle and antisocial facets) psychopathic traits in maximum-security male inmat...
