Theoretical adequacy is an concept that comes up in some form or another in various readings in the hci literature. More often than not, authors express concern that hci is currently (or soon-to-be) theoretically inadequate. But what does this mean?
What is theoretical adequacy? Is it the degree to which knowledge produced and published in a discipline is adopted and applied in a profession? Or does it refer to our production (or lack thereof) of scientific explanations of the phenomena we study? For the former, adequacy would be a high adoption and application of disciplinary knowledge in professions. And “theory” is really just another word for knowledge produced (primarily?) in a discipline. For the latter, adequacy could be a numbers game (how many theories do we produce?) or a utility game (do our theories have high scientific utility) or even an interest game (are the theories we generate interesting?).
Whatever meaning we choose, it seems reasonable to claim that theoretical adequacy is important. It seems important that we concern ourselves with the adoption of disciplinary knowledge in the professions (but maybe we should stop using the word ‘theory’ as shorthand for disciplinary knowledge since it does not describe all knowledge produced in the disciplines…). It also seems important that the theories we produce have a high degree of scientific utility or interest. But if I set out to address the applicability of disciplinary knowledge in the professions then I may set aside entirely my concern with scientific utility. Intention and meaning are intertwined, and this message gets lost in the literature.
We can’t hope to address theoretical adequacy without addressing its meaning.
