In every measured group, conservatism correlated positively with ethnocentrism and anti-Semitism

Evidence

Finally the scores of the PEC Scale did not correlate as highly with scores on the A-S Scale and the E Scale as did the scores on the latter two scales with one another. It is noteworthy that, of the thirty or so correlations calculated for different groups, none was negative. In short, neither ethnocentrism nor anti-Semitism ever showed a tendency to go with leftist liberal views; the conservative was always more ethnocentric and anti-Semitic but the association was not strong. — John T. Jost and Jim Sidanius, Political Psychology, 465

Categorization

• XREF: Connects to the broad empirical literature on ideological asymmetry in prejudice, since across all thirty correlations the direction never reversed despite weak magnitudes. — connects to: Empirical results failed to link ethnocentrism directly to political-economic conservatism — Rolf Wiggershaus, The Frankfurt School: Its History,…, 1801
• SEED: An essay angle: the zero-negative correlations finding as evidence for a directional (not merely correlational) link between conservatism and outgroup hostility — and what later replications with modern scales do and don’t confirm.
