“…The perception that intergroup relations is a zero-sum game, whereby gains for one group imply losses for other groups (e.g., Esses et al, 1998;Ruthig et al, 2017), as opposed to a positive-sum game (e.g., Deutsch, 2006), decreases advantaged groups' support for actions and policies benefitting disadvantaged groups (e.g., Radke et al, 2018). Two papers in this special issue provide further empirical support for the generalizability of this effect both cross-culturally (Kosakowska-Berezecka et al, 2020), and across various contexts of social inequality, that is, racism, heterosexism (Stefaniak et al, 2020), and sexism (Kosakowska-Berezecka et al, 2020). The reason why endorsing zero-sum beliefs represents a barrier to the advantaged group's engagement is because these beliefs are linked to fear about losing their privileged status (Stefaniak et al, 2020), and more hostile attitudes towards the disadvantaged group (Kosakowska-Berezecka et al, 2020).…”
