偏见是社会心理学中一个重要的领域。本文尝试梳理分析产生偏见行为的影响因素。我们发现,持有实体论观点的个体和具有权威主义人格的个体更容易对他人产生偏见行为,而错误的归因会强化个体对他人的刻板印象,使个体做出更多的偏见行为。此外,社会层面上看,个体所感知到的外部环境的威胁、个体渴望得到的社会认同、个体所面临的从众效应、媒体的舆论导向等因素都会对个体的偏见行为产生影响。 Prejudice is an important area in social psychology. This article attempts to sort out the factors that influence the behavior of prejudice. We find that individuals with substantive arguments and individuals with authoritarian personalities are more likely to prejudice others, and erroneous attributions reinforce individual stereotypes of others and make individuals more prejudiced. In addition, at the social level, such factors as the threat to the external environment perceived by the individual, the social identity the individual desires to get, the conformity effect that the individual faces, and the media-oriented orientation of the media all influence the individual’s prejudice.
