The combined effect of ratee's bodyweight and past performance information on performance judgments.

Few studies have examined how various biases operate in combination to influence performance judgments. Along these lines, the current study used experimental methods to test four competing models of the combined influence of ratee's bodyweight and past performance information on performance judgments. Results were consistent with an additive model, such that ratee's bodyweight and information about ratee's past performance combined independently to affect performance judgments. Consistent with a double disadvantage effect, the least favorable performance judgments were made for an overweight ratee with poor previous performance. Finally, mixed evidence was obtained for the interaction of ratee's bodyweight and perceptions of ratee's physical attractiveness, such that high-perceived attractiveness buffered against the otherwise negative performance ratings associated with overweight status.
