According to the latest post on Hemant’s blog,
a study published by Baylor University researchers finds that “Priming Christian Religious Concepts Increases Racial Prejudice” (PDF).
Basically, the researchers presented subjects with subliminal flashes of words, purportedly to test their ability to detect and differentiate between words versus non-word letter groups seen for only a brief period of time (less than 100ms). Some subjects saw neutral words, like butter or house, while others saw words associated with Christianity, such as Christ, faith, Bible and gospel. They then ran the subjects through a battery of situational questions designed to determine their degree of hostility towards the African Americans in the situations.
Kate Shellnutt summarized the conclusions quite nicely on HoustonBelief:
Researchers offer some possible explanations for why these Christian terms have such negative effects. They can cue fundamentalism or political conservatism, which can isolate “out-groups,” or echo the notion of the Protestant work ethic, which has been connected with anti-Black attitudes, the study said.
The researchers didn’t draw any larger conclusions from this (i.e., that most Christians are racist or anything quite so extreme), though they did insist it was causal rather than correlational.
