This is a data report for a scale that is in development called the Equalitarianism Scale, which measures perceptions of group differences. The data reported here are from 8 studies (n=3274) that tested other hypotheses, but that also included the Equalitarianism Scale. This scale contains 18 items measuring five highly related assumptions about group differences: (1) all groups are equal on all traits and abilities (a belief we call cosmic egalitarianism), (2) prejudice is ubiquitous in modern society, (3) the only reason groups differ is due to prejudice and discrimination, (4) anyone who asserts that groups differ biologically is justifying their own prejudices, and (5) we can and should make all groups equal in society, alpha= .92. The entire scale strongly correlates with more liberal ideology, r = .54, p<.001.
Recent scholarship has challenged the long-held assumption in the social sciences that Conservatives are more biased than Liberals, contending that predominantly liberal social scientists overlooked liberal bias. Here, we demonstrate that Liberals are prone to bias about relatively low-status groups (e.g. Blacks, women), and specifically are biased against information that portrays a high-status group more favorably than a lower status group. Six studies (n=2,921) support this theory. Liberals consistently evaluated the same study as less credible when the results concluded that a high-status group (men and Whites) had higher intelligence than a lower status group (women and Blacks) than vice versa. Ruling out alternative explanations of Bayesian (or other normative) reasoning, significant order effects in within-subjects designs in Studies 5 and 6 (preregistered) suggest that Liberals think that they should not evaluate identical information differently depending on which group is said to have a superior quality, yet do so.
