It's a very long read but interesting. The useful bits would be
Second, contrary to popular sentiment, stereotypes are usually accurate. (Not always, to be sure. And some false stereotypes are purposefully promoted in order to cause harm. But this fact should further compel us to study stereotype accuracy well so that we can distinguish truth from lies in this area).
That stereotypes are often accurate should not be surprising to the open and critically minded reader. From an evolutionary perspective, stereotypes had to confer a predictive advantage to be elected into the repertoire, which means that they had to possess a considerable degree of accuracy—not merely a "kernel of truth."
The notion of stereotype accuracy is also consistent with the powerful information-processing paradigm in cognitive science, in which stereotypes are conceptualized as "schemas," the organized networks of concepts we use to represent external reality. Schemas are only useful if they are by and large (albeit imperfectly) accurate. Your "party" schema may not include all the elements that exist in all parties, but it must include many of the elements that exist in many parties to be of any use to you as you enter a room and decide whether a party is going on and, if so, how you should behave.

Conceptual, methodological, and ideological obstacles notwithstanding, research on stereotype accuracy has been accumulating at quite a pace since the 1960s. The results have converged quite decisively on the side of stereotype accuracy. For example, comparing perceived gender stereotypes to meta-analytic effect sizes, Janet Swim (1994) found that participants were, “more likely to be accurate or to underestimate gender differences than overestimate them.” Such results have been amply replicated since. According to Lee Jussim (2009) and colleagues at Rutgers University-New Brunswick, “Stereotype accuracy is one of the largest and most replicable effects in social psychology.” Likewise, reviewing the literature, Koenig and Eagly (2014) concluded that, “in fact, stereotypes have been shown to be moderately to highly accurate in relation to the attributes of many commonly observed social groups within cultures.”
