The Dark Triad (DT) personality includes Machiavellianism, psychopathy, and narcissism. Forming interpersonal impression seems to be a key component for social disability in DT, but the underlying mechanism has been poorly understood. Participants were requested to evaluate impressions for 10 characteristics of twelve people including positive, negative, and neutral episodes. There were two experimental conditions for presenting order of episodes: negative to positive transition (NP) and positive to negative transition (PN). Participants also completed questionnaires assessing DT personality. Results indicated that individuals with higher DT personality showed greater changes in interpersonal impressions in the PN condition than individuals with lower DT. This pattern of results was not obtained in the NP condition. These results suggest that individuals with higher DT have biased sensitivity to negative information in interpersonal impression formation. Our data provide important evidence for understanding the characteristic of DT personality.
