Learning of one’s ingroup’s historical harm triggers outgroup dehumanization responses

Evidence

It is this measure of dehumanization that we used to investigate the effects of learning … In a first study, we assigned participants, U.K. citizens, to either a high-impact condition, in which they learned that the arrival of the British in Australia had a dramatic impact on the life of Aborigines (causing a sharp decrease in their population due to military operations by the British as well as diseases introduced by the British settlers) or to a low-impact condition, in which a decline in the number of Aborigines happened shortly after the arrival of the British, but their number subsequently stabilized to a level similar to that prior to the arrival. After reading one of these two accounts, participants indicated to what extent they estimated the capacity of Aborigines to feel a series of emotions. — Roderick M. Kramer, Geoffrey J.
