The implications of the shifting standards model for understanding behavior toward stereotyped groups were examined in two studies on gender and athleticism. Participants played the role of co-ed softball team managers, who made team selections, position assignments, and judgments about a series of male and female players. The data supported three hypotheses: (a) Stereotypes of male superiority as athletes lead to the use of shifting standards to judge athletic performance; (b) zero-sum behaviors (allocation of limited resources) show evidence of pro-male bias, whereas non-zero-sum behaviors (verbal and nonverbal reactions) show evidence of pro-female bias; and (c) objective judgments are somewhat better predictors of zero-sum behaviors, whereas subjective judgments are better predictors of non-zero-sum behaviors.
