Interactional Expertise

Interactional expertise is part of a more complex classification of expertise developed by Harry Collins and Robert Evans (both based at Cardiff University) and first published in Social Studies of Science in June 2002 (Collins and Evans 2002). In this initial formulation interactional expertise was part of a threefold classification of substantive expertise that also included ‘no expertise’ and ‘contributory expertise’, by which they meant the expertise needed to contribute fully to all aspects of a domain of activity.
