What is collaborative cognition?

Collaborative cognition is a concept in personal epistemology: Teams that share mental models coordinate better than teams that do not.

Example: A navigation team on a Navy vessel brings a ship into harbor. No single person holds the full picture. The bearing recorder, the plotter, the pelorus operators, and the officer of the deck each hold a fragment of the schema — compass bearings, chart positions, timing, environmental context. But because they share a schema for how a fix cycle works (sight a landmark, call the bearing, record it, plot it, compute the position), they coordinate without needing to explain their reasoning at each step. When the system works, the team's cognition exceeds what any individual could produce alone. That is the power of a shared schema.

This concept is part of Phase 11 (Schema Foundations) in the How to Think curriculum, which builds the epistemic infrastructure for schema foundations.
