Although acquiring information can provide numerous benefits, people often opt to remain ignorant. We define information avoidance as any behavior designed to prevent or delay the acquisition of available but potentially unwanted information. We review the various literatures that examine information avoidance and provide a unique framework to integrate the contributions of these disparate areas of research. We first define information avoidance and distinguish it from related phenomena. We then discuss the motivations that prompt information avoidance and the factors that moderate the likelihood of avoidance. Finally, we discuss individual differences that predict preferences for information avoidance. We conclude by evaluating the current state of research on information avoidance and discussing directions for future research.

Members of partisan social groups often exaggerate how much their own opinions differ from those of their rivals. In the present two studies, partisans estimated their own and their rivals' attitudes toward different issues related to the social conflict and also made a variety of evaluative judgments about their own and the rival group. The authors found that (a) partisans perceive more disagreement with their rivals about values that are central to their own sides' ideological position than those that are central to their rivals' position and (b) perceptions of disagreement about the partisans' own central values are what predicts partisans' global evaluations of members of the outgroup (e.g., disliking, trait stereotypes, perceived similarity). Furthermore, partisans believed their adversaries were motivated by an opposition to the partisans' own core values rather than by promotion of the adversaries' core values. Discussion concentrates on the theoretical and applied implications of these findings.
