In an information search model, evaluative concerns during intergroup interaction are conceptualized as a joint function of uncertainty regarding and importance attached to out-group members' views of oneself. High uncertainty generally fosters evaluative concerns during intergroup exchanges. Importance depends on whether out-group members' evaluations are perceived as diagnostic of one's social standing and outcomes. Perceived diagnosticity can arise from the out-group's control over resources (contingency) and/or ability to provide accurate assessments (expertise) and is a function of the relative status of one's group and the perceived legitimacy of the group status difference. Evaluative concerns trigger information search efforts and forms of uncertainty reduction that have a variety of negative downstream effects. Implications for efforts to improve intergroup relations are discussed.
