Love thy (Ukrainian) neighbour: Willingness to help refugees depends on their origin and is mediated by perceptions of similarity and threat.

Prejudice and discrimination against minorities can be a powerful tool for populistic and reactionary political movements, and it is therefore crucial to study its determinants. The aim of this research is to develop the understanding of a possible mechanism of such discrimination: cultural distance. In a pre-registered survey experiment with a between-subjects design, we draw on the large increase in intra-European refugee migration from Ukraine, to test whether refugees from another ongoing conflict in (culturally distant) Yemen are treated differently than (culturally similar) Ukrainian refugees by British participants (N = 1545).
