Happiness and stereotypic thinking in social judgment.

Four experiments examined the effects of happiness on the tendency to use stereotypes in social judgment. In each experiment, individuals who had been induced to feel happy rendered more stereotypic judgments than did those in a neutral mood. Experiment 1 demonstrated this phenomenon with a mood induction procedure that involved recalling life experiences. Experiments 2 and 3 suggested that the greater reliance on stereotypes evident in the judgments of happy individuals was not attributable to cognitive capacity deficits created by intrusive happy thoughts or by cognitively disruptive excitement or energetic arousal that may accompany the experience of happiness. In Experiment 4, happy individuals again were found to render more stereotypic judgments, except under conditions in which they had been told that they would be held accountable for their judgments. These results suggest that although happy people's tendency to engage in stereotypic thinking may be pervasive, they are quite capable of avoiding the influence of stereotypes in their judgments when situational factors provide a motivational impetus for such effort. Discovering the conditions under which group stereotypes are likely to be applied in forming impressions of and making judgments about individuals has been an issue of perennial interest in social psychology. Factors such as information overload (Pratto Stangor & Duan, 1991) and task difficulty (Bodenhausen & Lichtenstein, 1987), for example, have been shown to increase the social perceiver's reliance on stereotypic preconceptions (for a review, see Hamilton & Sherman, in press). In the present research, we investigated the role of emotion, specifically happiness, in the application of stereotypes during social information processing. Does being happy have any impact on the likelihood of stereotyping others? If so, what is the mechanism involved? It was these questions that we sought to address. Interest in the relationship between emotion and stereotyping is certainly not new. However, previous attempts to understand the role of affective experience in prejudice and stereotyping have focused almost exclusively on the impact of negative emotions. Conventional wisdom indicates that it is during times of stress, anxiety, or hostility that prejudice and stereotypes are most likely to emerge and exert their influence on social perception. Psychological research lends credence to the idea that anger, conflict, frustration, and anxiety are indeed associated with
