• Previous research on mock-jury trials has shown an explicit attractiveness bias in participant attributes of innocence. This study used the Implicit Relational Assessment Procedure (IRAP) to measure attractiveness-bias in implicit evaluations of innocence or guilt with a sample of 46 college students.

  Alternate IRAP trial-blocks required participants to affirm relations consistent and inconsistent with attractiveness bias (attractive-innocent/unattractive guilty versus unattractive-innocent/ attractiveguilty). Faster responding across consistent trial-blocks was interpreted in terms of implicit stereotype.

  Participants’ beliefs about the importance of their own appearances were examined using the Beliefs about Appearances Scale (BAAS) and explicit attractiveness ratings for the IRAP photographic stimuli were measured using Likert scales; analysis examined relationships between these beliefs and IRAP scores. Results revealed statistically significant attractiveness bias for both male and female participants; specifically, both a pro-attractiveness and anti-unattractive bias. Findings are discussed regarding research in implicit evaluations of innocence or guilt and effects of attractiveness bias
