We recruit naturally-existing groups of people living in a slum and experimentally test whether they contribute more in favour of their group as compared to another group ('in-group bias'). We find that the in-group bias decreases the higher the heterogeneity among group members, and when a more inclusive identity is activated.

Abstract
We recruit naturally-existing groups of people living in a slum and experimentally test whether they contribute more in favour of their group as compared to another group ('in-group bias'). We find that the in-group bias decreases the higher the heterogeneity among group members, and when a more inclusive identity is activated.
