Bicultural and Generalized Identity Integration Predicts Interpersonal Tolerance

In this article, we test the hypothesis that individuals with higher levels of identity integration—or those who perceive their different social identities as more blended and harmonious—will exhibit greater interpersonal tolerance toward others holding dissimilar values and preferences. Three studies examined this hypothesis using bicultural identity integration (or perceived blendedness and harmony between multiple cultural identities) and generalized identity integration (or perceived blendedness and harmony between one’s social identities in general). We find that individuals who perceive higher levels of blendedness, but not harmony, between their social identities are more tolerant of dissimilar others, as demonstrated by making more positive trait inferences about them. We also find that experimentally increasing identity integration leads to more positive trait inferences. Our findings have theoretical and practical implications for managing conflict between individuals and groups.
