Californian prisoners showed higher ethnocentrism and conservatism than the general population.

Evidence

It was in fact shown that, in a sample of 110 prisoners in San Quentin, ethnocentrism and political and economic conservatism, although not especially anti-Semitism, were clearly more marked than in other groups, and unprejudiced subjects appeared less frequently than in other groups. But this conclusion was not particularly emphasized or exploited for propaganda purposes. — Rolf Wiggershaus, The Frankfurt School, 400
