Manchester students rated Oxford students higher on stereotypic traits than their own ingroup

Evidence

There is also some evidence for in-group devaluation on stereotypic dimensions provided by studies using social identity theory’s own empirical paradigm. Spears and Manstead (1989), for instance, found that students from Manchester University rated the typical Oxford University student to be more “hard-working,” “self-assured,” “articulate,” and “intellectually minded” than the typical Manchester student. Even if such differences were validated by objective criteria such as grades and test scores or if they were widely believed by most of society, one might expect subjects to defend the ingroup “at all costs,” in the words of Hogg and Abrams (1988, p. 76). — John T.
