Groups we agree with seem more unified than groups we oppose

Evidence

In a related vein, supportive opinion groups are perceived as more entitative than oppositional opinion groups. Also, more extreme opinion groups tend to be perceived as particularly entitative. However, the precise motivations underlying these effects are not fully understood (Askevis-Leherpeux, 2005). — Roderick M. Kramer, Geoffrey J. Leonardelli, Robert W.

Categorization

• XREF: Surprising twist for the ingroup/outgroup thread: one would expect out-groups to be homogenized (entitative), yet here oppositional groups are seen as LESS entitative — complicates the classic out-group homogeneity finding.
• QUESTION: How does this reconcile with out-group homogeneity research, where opposing out-groups are typically seen as monolithic? Perhaps entitativity judgments are context-sensitive: moral opposition homogenizes, disagreement fragments.
• corroborated: 2 independent passages support this claim — Roderick M. Kramer, Geoffrey J. Leonardelli, Robert W. Livingston, Social Cognition, Social Identity, and…, 260
