What the account says

Self-categorization theory (Turner et al. 1987, as quoted in the source) has groups perceived “as one whole entity” through categorization into an equivalence class, made salient by meta-contrast and accentuated by depersonalization. The account here splits that in two:

  • Category membership: oneself and others share a property. Under accentuation they look interchangeable. Out-group homogeneity is a category effect.
  • Group entity: oneself and others are bound into a unit, perceived from cues to collective intentionality: mutual gaze, synchronous or complementary motion, joint attention, explicit shared mental states. Crowd behaviour is a group effect.

The first is neither sufficient nor necessary for the second.

What was actually shown

Nothing at first hand. The source gives a conceptual argument (sets versus things; orchestras and families) and summarizes four experiments under review (Skorich et al.). In minimal-group and who-said-what paradigms, groups defined by mental states drew more in-group favouritism and more tracking than groups defined by physical properties. That could have come out otherwise: physical-property groups could have done as well. The record has not read the experiments.

What this does not say

  • Not that categorization does nothing. Category effects such as self-stereotyping and out-group homogeneity remain, and the source keeps them as SCT1.0’s special case.
  • Not that collective intentionality requires a group subject. It is “intentionality spread across what are otherwise individual intentional agents”, perceived by the individual. The account is about perception, not ontology.
  • Not the rest of SCT2.0. Conceptual atomism, the language of thought and the intractability of meta-contrast are argued in the same paper but are not part of this claim, which stands or falls with the category/entity distinction and the mental-state evidence.

Bearing

  • Rival to THEORY-1114 on the mechanism of group perception and of salience. They agree that self-perception varies with context; they disagree on whether meta-contrast is what forms the group.
  • THEORY-126 uses collective intentionality to mark We-mode collective emotion. This account uses it to mark perceiving a group at all. If both hold, We-mode emotion presupposes a perceived group entity.
  • CASE-104 and QUESTION-119. It distinguishes the fanbase as a category (people who support the club) from the fanbase as a group entity (fans seen to share an intention: a chant, a boycott). Only the second is a candidate holder of a stance.
