Why a moratorium on microaggressions policies is needed.

Microaggression, like most and perhaps virtually all psychological constructs, such as intelligence, extraversion and schizophrenia, is what philosophers term an open concept, characterised by intrinsically fuzzy boundaries, an indeterminate list of indicators, and an unclear inner nature. Open concepts are not necessarily problematic. To the contrary, they often allow researchers to explore a poorly understood phenomenon in an open-ended way.
