Physical resemblance triggers trait inferences while coordinated action triggers goal inferences

Evidence

Ip, Chiu, and Wan (2006) demonstrated that physical similarity and coordinated action among group members trigger two separate routes to perceived entitativity. They orthogonally manipulated physical similarity and coordinated action among group members. The researchers found that manipulating the physical similarity of group members increased trait inferences about the group, that is, perceivers inferred that the group had stable, underlying traits. When the group members were physically dissimilar but were coordinated in action, perceivers inferred that the group members had common goals. — Roderick M. Kramer, Geoffrey J. Leonardelli, Robert W.

Categorization

• XREF: This experimental separation of similarity-driven trait inference from action-driven goal inference bears directly on the reader’s prejudice thread: if a minority group is perceived as physically similar/interchangeable, observers default to essentialist trait stereotyping, whereas coordinated visible action shifts perception toward goal attribution. — connects to: Perceived physical resemblance licenses presumptive knowledge of others’ inner lives — David Theo Goldberg, The Threat of Race: Reflections on…, 70
• SEED: Article angle: when social movements organize visibly coordinated action, outgroup observers shift from essentialist stereotyping (inherent traits) to agency framing (political goals) — testable implication for how protest visibility changes prejudice.
• corroborated: 3 independent passages support this claim — Roderick M. Kramer, Geoffrey J. Leonardelli, Robert W. Livingston, Social Cognition, Social Identity, and…, 229
