Sharing beliefs, particularly moral beliefs, is a way to establish social connections. We hypothesized that ostracism leads people who are high in the need to belong to adhere to the moral beliefs of an ingroup, and that moralizing the beliefs of one's group increases the willingness to endorse extreme behavior on behalf of the group. Across two studies, participants were ostracized or included, rated the moral relevance of their group values, and indicated their endorsement of extreme behavior on behalf of the group. Across studies, ostracism increased group moralization in participants high in the need to belong. In Study 2, group moralization translated into endorsement of extreme behavior. Our findings suggest that morality serves a binding function that may be channeled into extreme behaviors. (120 words) [ABSTRACT FROM AUTHOR]

Much of the justification for granting foreign aid is to support nations and international policies promoting one's national values. However, little to no research has examined how perceptions of similarity between nations, especially value similarity, drive feelings toward other nations and policy preference. In 3 studies using United States samples, we examine relationships between dimensions of country-level similarity, perceptions of value similarity and threat, and policy support. Correlational data and manipulations of value similarity suggest that perceptions of value similarity are the most consistent predictor of support for foreign aid and are consistently driven by ally status and cultural similarity.
