Dimensions of stereotypes about groups

People perceive social groups along stereotype dimensions. Several models of social evaluation identify so-called horizontal (relational, warmth, communion) and vertical (achievement, competence, agency) judgments, also known as the Big Two. Each has two facets, respectively indicating perceived morality and friendliness for horizontal, plus ability and assertiveness for vertical. Perceivers also locate groups within socio-political structures, such as socioeconomic status and ideological beliefs. These six commonly used stereotype dimensions (morality, friendliness, ability, assertiveness, status, beliefs) each predict specific and pragmatic behaviors toward (members of) groups, including approach, investment, cooperation, and inclusion. Overall, the trait dimensions correlate positively (e.g., the two respective facets of each of the Big Two), but contextual goals can override general patterns. For example, when people encounter two unequal groups and strive for social justice and harmony, the horizontal and vertical judgments correlate negatively. Contextual goals and transient motives also moderate the importance of the stereotype dimensions. We conclude by suggesting avenues for future research.
