Lay beliefs about the causes of and solutions to dehumanization and prejudice: do nonexperts recognize the role of human–animal relations?

摘要

We investigate laypeople's beliefs about the causes of and solutions to out-group dehumanization and prejudice. Specifically,we examine whether nonexperts recognize the role that beliefs in the human–animal divide play in the formation and reduction of intergroup biases, as observed empirically in the interspecies model of prejudice. Interestingly, despite evidence in the present study that human–animal divide beliefs predict greater dehumanization and prejudice, participants strongly rejected the human–animal divide as a probable cause of (or solution to) dehumanization or prejudice.We conclude with a meta-analytic test of the relation between human–animal divide and prejudice (mean r = .34) in the literature, establishing the human–animal divide as an important but largely unrecognized prejudice precursor. Applied implications for the development and implementation of prejudice interventions are considered.
