If someone says, “Asians are good at math” or “women are empathetic,” I might interject, “you're stereotyping” in order to convey my disapproval of their utterance. But why is stereotyping wrong? Before we can answer this question, we must better understand what stereotypes are and what stereotyping is. In this essay, I develop what I call the descriptive view of stereotypes and stereotyping. This view is assumed in much of the psychological and philosophical literature on implicit bias and stereotyping, yet it has not been sufficiently defended. The main objection to the descriptive view is that it fails to include the common‐sense idea that stereotyping is always objectionable. I argue that this is actually a benefit of the view. In the essay's final part, I put forward two hypotheses that would validate the claim that stereotyping is always morally or epistemically wrong. If these hypotheses are false—which is very likely—we have little reason to build moral or epistemic defect into the very idea of a stereotype. Moreover, we must abandon the seemingly attractive claim that judging individuals based on group membership is intrinsically wrong.
