Contributory Expertise
The capacity to do the work of a field — to contribute original knowledge, advance the practice, exercise the judgment that distinguishes participants from observers — and the specific competence Collins identifies as structurally unavailable to systems that have not been socialized into the community.
Contributory expertise is the counterpart to interactional expertise in Collins's taxonomy. Where interactional expertise is the fluency to discuss a domain acquired through linguistic engagement, contributory expertise is the competence to do the domain's work acquired through participation in its practices. The physicist who detects a gravitational wave possesses contributory expertise. The journalist who can discuss the detection with technical precision does not. The distinction matters because the AI revolution has produced machines with comprehensive interactional competence and no contributory competence at all — and the structures of professional work assume that interactional fluency reliably signals contributory capacity.

The distinction becomes clearest at the boundary between knowing-that and knowing-how — between being able to discuss a practice and being able to perform it. Gilbert Ryle's version of this distinction treats knowing-how as the manifestation of individual skill. Collins's version treats it as inherently
