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). We measured stated willingness to help and to hire refugees. Moreover, the participants were offered the chance to donate their own earnings from survey participation to real charity drives aimed at the respective refugee groups. Thus, we are able to examine both stated and actual helping behaviours that captured both autonomy- and dependency-oriented forms of helping. As expected, participants were more willing to help, hire and donate money to Ukrainian refugees, and these effects were mediated by higher perceived similarity and lower perceived threat from Ukrainians compared with Yemenis.
