Discrimination at young age: Experimental evidence from preschool children

Discrimination is an ubiquitous phenomenon in many societies, but little is known about its origins in childhood. In a framed field experiment, we let 142 three to six-year old preschool children allocate a fixed endowment between an in-group and an out-group receiver in two domains (gender and preschool group affiliation). Discrimination is prevalent in our subjects, since they allocate more than half of their endowment to the in-group. The extent of discrimination is similar in both domains, suggesting that it is a universal, as opposed to a domain-specific, trait. Analyzing age dynamics, discrimination tends to get stronger with age.
