When less is more: defensive national identity predicts sacrifice of ingroup profit to maximize the difference between groups

We propose that defensive forms of identity (i.e., nationalism and national narcissism) can harm the nation through a tendency to maximize the difference between own and other groups in resource allocation. We test this hypothesis by adopting a classic social psychological paradigm, the Tajfel’s matrices, to real-life scenarios designed in the COVID-19 context. We captured maximizing the difference as a preference for one’s nation being allocated more medical resources relative to other countries, but at the expense of absolute ingroup profit. In Studies 1 and 2, defensiveness in national identity predicted this counterproductive strategy that ultimately benefits neither ingroup nor outgroup. In experimental Study 3, inducing ingroup disadvantage led to a greater tendency to maximize the difference. The results provide evidence that defensive national identity might be liked to support for policies that offer a positive intergroup comparison, but simultaneously harm one’s own ingroup.
