Liberals who fear conservatives: intergroup political bias in the contemporary Italian context

Data described the effect of different political stimuli on the expression of prejudice of left and right-wing participants. In three studies we presented our participants with images of politicians, ideological words and items referring to political ingroup/outgroup and asked to express emotional and cognitive evaluations. Analysis revealed that left-wing participants expressed higher bias compared to right-wing ones, regardless of the stimuli. Right-wing participants expressed the bias only when ideological words were presented. The process that lead to this expression of political intergroup bias seems mediated by a different perception of threat that is higher for left-wing participants.
