In-group bias on threat-relevant and threat-irrelevant traits, as a function of self-protective concerns triggered by ambient darkness. Canadians in a darkened room were especially likely to evaluate Iraqis less favorably than they evaluated fellow Canadians. This effect was specific to prejudicial perceptions on traits highly relevant to safety threats (“hostile,” “trustworthy”) but not to perceptions of equally evaluative but threat-irrelevant traits (“ignorant,” “open-minded”). Results based on Schaller et al. (2003).
