Abstract: | People judge others on simplified trait structures when evaluating the Big Five, which is referred to as implicit simplicity (IS: Beer & Watson, 2008). The present study investigated IS in minimally acquainted informal dyads. Hundred and eighty-six participants interacted for a short time on a task, and then provided self- and peer-ratings on the IASR-B5 (Trapnell & Wiggins, 1990). IS manifested in a global evaluative “halo-factor” with some accuracy and was related to perceivers’ interpersonal attraction ratings and personality traits. The driving forces behind IS are discussed. |
