This paper considers in conceptual terms the extent to which pre-service teachers’ disengagement with philosophy of education might usefully be explained in terms of the mistaken charge of (1) ‘epistemic trespassing’ frequently levelled against philosophers of education. This cohort charge philosophers of education with being ultracrepidarians—those who proffer opinions on subjects that they know nothing about. Contra this view, I argue that casting philosophers as epistemic trespassers—lofty theorists with nothing meaningful to contribute to professional practice—is a wrongful charge, or ‘epistemic (...) vice’, based on a series of epistemic mistakes. These, individually and collectively, lead to a series of troubling costs in terms of impoverished professional formation and practice. To diagnose a plausible explanatory account of this phenomenon, I briefly turn to what I consider the main causes of this misattribution—more precisely—the four secondary category mistakes pre-service teachers make. Naturally a qualification is required. I contend these epistemic mistakes can rightfully be attributed to *some pre-service teachers in such determinations, which include: (2) misunderstanding standpoint epistemology (SE) in terms of automatic privilege being coextensive with first-personal authority (FPA); (3) overestimating the added value of deliberate/rational ignorance; (4) misguided intellectualist views of skills and expertise; and, (5) uncritical technicist attempts to emulate TikTok Exemplars with the allure of ‘Insta results’.
