When social fear is missing, so are racial stereotypes

Apr 12, 2010

Children with the genetic condition known as Williams syndrome have unusually friendly natures because they lack the sense of fear that the rest of us feel in many social situations. Now, a study reported in the April 13th issue of Current Biology, a Cell Press publication, suggests that children with Williams Syndrome are missing something else the rest of us have from a very tender age: the proclivity to stereotype others based on their race.

The findings support the notion that social fear is at the root of . The researchers say the results might also aid in the development of interventions designed to reduce discriminatory attitudes and behavior towards vulnerable or marginalized groups of society.

"This is the first study to report the absence of racial stereotypes in any human population," said Andreas Meyer-Lindenberg of the Central Institute of Mental Health, Mannheim/University of Heidelberg, who coauthored the paper with Andreia Santos and Christine Deruelle of the Mediterranean Institute of in Marseille.

Previous studies have shown that stereotypes are found ubiquitously in typically developing children—as early as age 3—as they are in adults, Meyer-Lindenberg explained. Even children with autism display racial stereotypes, despite profound difficulties in daily social interaction and a general failure to show adapted social knowledge.

In their study, the researchers showed children a series of vignettes with people differing in race or gender and asked the children to assign positive or negative features to those pictured. Typical children made strongly stereotypical assignments both for sex roles and for race, confirming the results of previous studies. On the other hand, children with Williams syndrome showed no evidence for .

"The unique hypersociable profile of individuals with Williams syndrome often leads them to consider that everybody in the world is their friend," Meyer-Lindenberg said. "In previous work, we have shown that processing of social threat is deficient in people with the syndrome. Based on this, we suspected that they would not show a particular preference for own-race versus other-race characters. The finding that racial stereotypes in children with Williams syndrome were completely absent was nevertheless surprising in its degree."

The children with Williams syndrome did make stereotypical sex role assignments just like normal children. That finding suggests that different forms of stereotyping arise from different brain mechanisms, the researchers say, and that those mechanisms are selectively affected in some way by the genetic alteration that causes (the loss of about 26 genes on chromosome 7).

Might the world be a better place if we all had Williams' syndrome? Is Williams syndrome a disease or the next step in human evolution? Would it be ethically wrong to genetically induce Williams syndrome onto hate crime offenders if such a procedure were possible?

What I'm trying to ask basically is, do humans really need those 26 or so genes on chromosome 7 since we've moved past hunter-gathering to sedentary lifestyles?

Any stereotyping of physical features must be based on evolution.

That's right marjon, white pride all the way!

Just remember, everyone else is racist and homophobic, not you. Your feelings, even if they are bigoted, are justifiable at all times, but just yours.
