European by action: How voting reshapes nested identities

Although research has questioned the stability of identities, we know little about identity change. I examine a political event as a driver of identity change, namely the Brexit vote. I contend that the act of voting, choosing between two options, boosts the European and British identity underlying the vote choice. I test whether the increased identification with Europe or Britain comes with a reduction in the other identity. Using British Election Study panel data in a two-way fixed-effects design, I show that voting to remain increases identification with Europe but voting to leave does not increase British identification for Leavers. However, voting has no impact on how Remainers identify with Britain or Leavers identify with Europe. The results contribute to the growing literature on the link between politics and identities.
