I Can't Help It. I Was Born This Way
Is politics in the genes?
Genetic researchers are trying to prove that social attitudes can be inherited, and have discovered strong correlations between the two.
So far, the political connection has relied on studies by Lindon Eaves, professor of human genetics and psychiatry at Virginia Commonwealth University. About 8,000 sets of identical and fraternal twins answered a series of questions on topics such as school prayer, nuclear power, women's liberation and the death penalty.
Identical twins, who share their entire genetic code, answered more similarly than fraternal twins, who are no more similar than non-twin siblings.
If you assume that both identical and fraternal twins share an environment, then the disparity between the results must be genetic, Hibbing and colleagues conclude.
