Rejecting all group stereotypes erroneously implies all groups are identical

Evidence

In an effort to denounce these inaccurate beliefs, “There has grown up in social and educational psychology a literature and teaching practice which says that all stereotypes of group differences are false, and, implicitly, that all groups are on average identical.” (Campbell, 1967, p. 823; Allport, 1954/1979, p. 87, made essentially the same point.) Campbell noted that while social psychologists have been right in emphasizing the general errorfulness of stereotypes, the “problem is how to state the errors, without claiming that all groups are identical” (p. 824). — , Rudman, Laurie A - On the Nature of…, 840
