Collective Intentionality

Collective intentionality is the philosophical problem of how multiple individuals can share a single mental state — a joint belief, a shared intention, a we-attitude — that is not reducible to the sum of the individual mental states of those individuals. When two people lift a table together, neither one intends merely that their own hands move; each intends that we lift the table. This we-intention is not decomposable into two individual intentions without losing something essential.

Collective intentionality is the theoretical foundation of speech act theory as applied to institutions: John Searle argues that institutional facts (money, property, marriage, government) exist in virtue of collective acceptance of constitutive rules, and collective acceptance requires collective intentionality. The philosophical puzzle: how can a mental state be genuinely collective without positing a group mind? Searle's answer is that collective intentionality is a primitive irreducible feature of human psychology. This is empirically plausible but philosophically unsatisfying.

The stakes for cultural theory are high: if collective intentionality is irreducible, then social ontology cannot be built from individual psychology alone, which places a permanent limit on methodological individualism in the social sciences. Entire research programs in organizational theory, game theory, and cultural evolution rest on whether collective intentionality can be dissolved into individual components. So far, no consensus dissolution has been achieved.
