Prejudice is hard-wired into our brains

Arizona State University:

Contrary to what most people believe, the tendency to be prejudiced is a form of common sense, hard-wired into the human brain through evolution as an adaptive response to protect our prehistoric ancestors from danger.

So suggests a new study published by Arizona State University researchers in the May issue of the "Journal of Personality and Social Psychology," which contends that, because human survival was based on group living, "outsiders" were viewed as -- and often were -- very real threats.

"By nature, people are group-living animals -- a strategy that enhances individual survival and leads to what we might call a 'tribal psychology'," says Steven Neuberg, ASU professor of social psychology, who authored the study with doctoral student Catherine Cottrell. "It was adaptive for our ancestors to be attuned to those outside the group who posed threats such as to physical security, health or economic resources, and to respond to these different kinds of threats in ways tailored to have a good chance of reducing them."

Here is what the researchers did:

Neuberg and Cottrell had 235 European American students at ASU think about nine different groups: activist feminists, African Americans, Asian Americans, European Americans, fundamentalist Christians, gay men, Mexican Americans, Native Americans and nonfundamentalist Christians. The researchers then had the participants rate these groups on the threats they pose to American society (e.g., to physical safety, values, health, etc.) and report the emotions they felt toward these groups (e.g., fear, anger, disgust, pity, etc.).

Consistent with the researchers' hypotheses, findings revealed that distinct prejudices exist toward different groups of people. Some groups elicited prejudices characterized largely by fear, others by disgust, others by anger, and so on. Moreover, the different "flavors" of prejudice were associated with different patterns of perceived threat.

Follow-up work further shows that these different prejudices motivate inclinations toward different kinds of discrimination, in ways apparently aimed at reducing the perceived threat.

"Groups seen as posing threats to physical safety elicit fear and self-protective actions, groups seen as choosing to take more than they give elicit anger and inclinations toward aggression, and groups seen as posing health threats elicit disgust and the desire to avoid close physical contact," says Cottrell.

If prejudice really is hard-wired into our brains as a result of evolution, then it can be shifted around and mitigated at best, but never eliminated.

I think we see such a "shifting" of prejudice among many p.c.-types, who pounce on the slightest evidence of sexism, racism, or homophobia (real or imagined) yet decry the merest assertion of traditional Christian values as evidence of an encroaching theocracy.

The rest of my thoughts on this study are available here:
