The drift as such can have multiple causes, and in this article, we relate academic drift to the concepts of institutional logics and isomorphism from neoinstitutional organization theory, delineating policymaking, norm shifts and organizational action in response to uncertainty as three component processes of academic drift. Using the case of the organizational field of the Swedish higher education system and its recent 35-year history, we draw both empirical and theoretical conclusions, and demonstrate the weight of the research mission in the building of institutional legitimacy for university colleges.
