Social identity is a key construct to understand online community life. While existing online identity studies present a relatively static conception of identity, grounded in user profiles and other personal information, in this paper the authors investigate more dynamic aspects of identity, grounded in patterns of social interaction in Facebook community life, drawing on social science researc...

This article discusses the social identity approach (social theory and self-categorization theory) for understanding children’s ingroup biases in attitudes behaviors. It is argued that developmental research on bias will be enhanced by more fully considering implications of this approach. These include (a) conceptualization group identity, (b) importance reality epistemic motivation, (c) role p...

In an adverse selection framework with observable effort, voters can choose to condition their reelection choices on representatives’ effort alone, beliefs about representatives’ competence, or both of those jointly. We show that inducing social identiti...

This paper presents a novel experiment on identity and individual social preferences. Using a within subject design and new empirical methods, we find more than twenty percent of subjects destroy total income – at personal cost – to earn more than subjects outside their group. Minimal groups divide subjects according to arbitrary criteria, and political groups divide subjects according to party...
