San Quentin prisoners showed elevated ethnocentrism but not anti-Semitism

Evidence

In addition, if the evidence they hoped for were to be provided, it would be possible to dismiss anti-Semitism easily as something that was not a problem for the average citizen, for the `conforming anti-social person’, but only for deviant anti-social people who were frowned upon anyway. (Only two special groups were later examined: prisoners and psychiatric patients. 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, 1595
