The current study examined the effect of jury deliberation on the tendency for mock jurors to find attractive defendants guilty less often. It was expected that there would be an interaction between group deliberation (yes or no) and defendant's appearance (plain-looking or attractive). It was hypothesized that mock jurors who did not deliberate would be more likely to find a plain-looking defendant guilty and that deliberation would mitigate this effect. The study was a 2 x 2 between-subjects factorial design. Participants were assigned randomly to one of four conditions: attractive defendant/deliberation, attractive defendant/no deliberation, plain-looking defendant/deliberation, and plain-looking defendant/no deliberation. A total of 172 undergraduates from a small, rural college in Vermont contributed to this study: mock jurors were 70 men and 52 women, ages ranged from 18 to 52 years (M=20.5, SD=4.9). The hypothesis was supported. Mock jurors who did not deliberate were more likely to find the plain-looking defendant guilty, whereas mock jurors who deliberated were more likely to find the attractive defendant guilty.
