Collective intentionality is Tomasello's name for the cognitive capacity that enables institutional reality. When two people share a goal, the intentionality exists between them and dissolves when the interaction ends. When a community collectively recognizes that a person occupying a role has specific powers and obligations, the role exists independently of any particular interaction—it is constituted by the collective agreement and persists as long as the agreement holds. Money, property, marriage, law, scientific authority—all are collective intentional achievements. They exist because communities collectively intend them to exist. Remove the collective recognition, and the institutional reality vanishes. This capacity to participate in collectively constituted realities is uniquely human, emerging developmentally around age three as children begin to enforce norms and protest violations even when not personally affected.
The philosophical foundations of collective intentionality were laid by John Searle in The Construction of Social Reality (1995), which analyzed status functions—roles like 'president' or 'property owner' whose powers exist only through collective recognition. Tomasello's contribution was to ground Searle's analysis in developmental and evolutionary research, showing how collective intentionality emerges from the shared intentionality of dyadic collaboration. The three-year-old who protests when another child 'plays the game wrong' is already participating in collective intentionality—recognizing that the game has rules that exist independently of any player's preferences and that all players are bound by those rules. This normative understanding is the foundation of all subsequent institutional participation.
The scaling from dyadic to collective intentionality required evolutionary elaboration of the cognitive architecture. Shared intentionality between two individuals requires mutual awareness and shared goals. Collective intentionality requires the additional capacity to represent ourselves as a group with a collective identity, collective goals, and collective standards. The pronoun shift from 'you and I' to 'we' marks the transition. When a group says 'we believe this' or 'we prohibit that,' the group is exercising collective intentionality—binding its members to shared commitments that exist at the group level and that individuals cannot unilaterally revise. This capacity made complex institutions possible: tribes, then chiefdoms, then states, then civilizations built on layers of collectively constituted roles and norms.
Professional expertise is a status function constituted by collective intentionality. The doctor's authority to prescribe medication exists because the medical community, the state, and the broader public collectively recognize that individuals meeting specific training criteria possess epistemic authority in medical matters. The recognition is not merely legal; it is cognitive—the collective agreement that the expert knows things others do not and that this knowledge warrants trust. AI disrupts this collective intentionality by making expertise-level outputs accessible to non-experts. When a non-physician can generate a plausible diagnostic assessment using Claude, the collective recognition that physicians possess special knowledge comes under strain. The strain is not merely economic (non-experts can do what experts do) but institutional (the status function weakens when the knowledge it was based on becomes democratized).
The rebuilding of institutions for the AI age requires collective intentionality at the highest level—communities deliberating together about the roles, norms, and standards that should govern AI-augmented practice. This is not a technical problem with a technical solution. It is a collaborative cognitive and political achievement requiring exactly the kind of shared thinking that Tomasello's framework identifies as uniquely human. The communities that succeed will be those that protect the social and deliberative processes through which collective intentionality is constructed and maintained, even as AI tools make individual output production faster and smoother.
Tomasello developed the collective intentionality framework in his later career, building on John Searle's philosophical analysis and empirical work with children demonstrating that normative understanding emerges around age three. The synthesis appeared most fully in A Natural History of Human Thinking (2014) and A Natural History of Human Morality (2016), where Tomasello traced the evolutionary and developmental trajectory from individual intentionality through shared intentionality to collective intentionality, arguing that each stage built on the previous one and that collective intentionality was the cognitive foundation of institutional reality.
Institutional reality is collective achievement. Roles, norms, laws, and institutions exist because communities collectively intend them to exist—recognition can be withdrawn, and the reality dissolves.
Emerges from shared intentionality. The capacity to participate in collective norms develops from dyadic collaboration—children who engage in joint activities develop expectations of fairness and reciprocity that generalize into moral norms.
Normative enforcement is mutual. In human communities, norms are maintained through reciprocal monitoring—each member checking others and being checked—a distributed enforcement that AI collaboration cannot replicate.
Professional authority is a status function. Expert roles are collectively constituted; when AI democratizes expertise-level output, the collective recognition sustaining the expert's authority requires reconstruction.
Rebuilding requires deliberation. Adapting institutions to AI demands the kind of collaborative thinking—shared goals, mutual accountability, collective evaluation—that collective intentionality makes possible and that the transition risks displacing.
