Twins

From a WSJ review of a new book chronicling the Minnesota Study of Twins Reared Apart:

The Minnesota study’s IQ results hit a nerve years before their publication in 1990, overshadowing other controversies that might have been. Many of its findings are bipartisan shockers. Take religion, which almost everyone attributes to “socialization.” Separated-twin data show that religiosity has a strong genetic component, especially in the long run: “Parents had less influence than they thought over their children’s religious activities and interests as they approached adolescence and adulthood.” The key caveat: While genes have a big effect on how religious you are, upbringing has a big effect on the brand of religion you accept. Identical separated sisters Debbie and Sharon “both liked the rituals and formality of religious services and holidays,” even though Debbie was a Jew and Sharon was a Christian.

Just another example of the ‘God Gene’ at work, I suppose, and, as such, just another reminder that there is little or no prospect of ever weaning mankind off religion (Professor Dawkins, please note).
