Social identity is a person’s sense of who they are based on their group membership. Identities can assume many dimensions (ethnicity, gender, age, class and political ideologies) and these different domains increasingly overlap at a time of digital connectedness. The significant role of social identity on economic, political and social outcomes is well studied. The literature focuses on whether individuals adopt or reject the behaviour of the groups most closely associated to their individual attributes and on how increasing contacts across groups may reduce intergroup conflicts.
Due to lack of adequate data and the complexity of theoretical models, the fact that social identity and group formation may dynamically co-evolve is largely ignored within the quantitative strand of the literature. This omission may have important ramifications for the design of economic and social policies. Whenever social identities and personal interactions are involved then many studies suggest that network and identity shape each other. For example, the friendships that form at university may depend on religious identity, but religious beliefs are also modified by the social circles a student is exposed to. Other examples include situations in which an individual acquires a new social identity thanks to the exposure to new ideas through social networks, such as the popular unrest in the 2011 London riots, or the very recent “#me too” movement.
