I appreciate the point about diverse perspectives in a learning network. In an academic context, this is understood but sometimes in a limited way, as criticality within the discipline. Perhaps we also need to seek perspectives from without our disciplines. While there are concerns that ideas and language do not translate perfectly from one domain to another, staying within a single domain may cut us off from perspectives we need. Perhaps the Dunning-Kruger effect applies to bounded disciplinary domains, in the same way it describes my individual tendency to overestimate my grasp of a concept or field?
