Skepticblog is usually pretty good. Like this post about the Shermer’s trip to a TED-alike conference in Mexico.

Then the evolutionary biologist David Barash spoke about redirected aggression, recounting a story about how when his horse kicked his dog, his dog bit the horse. That’s directed aggression. More often than not, however, when A kicks B, B kicks C. Why? Reputation. If B does not kick C then others will start kicking him. (This assumes that if you kick A back, he’ll kick your butt for good.) Bush’s invasion of Iraq was redirected aggression from 9/11, says Barash, because there is no definitive state of Al Qaeda to kick back.

This one matches my expectations – and I like his conclusion:

why in the world did Proposition 8 — banning gay marriage — pass in my hyper-liberal state of California? I put the question to Hamer. His answer: a lot of liberals, especially in the African-American community, consider marriage to be a separate issue from other civil rights, and thus we’ve got a ways to go for gays to achieve equal standing under the law. Hamer cited one study in which people were asked “Do you think homosexuality is a choice or are people born that way?” Americans were split 50/50. But when asked “Should gays be allowed to marry?” the answer was an overwhelming “No” for those who think homosexuality is a choice, and “Yes” for those who think gays are born that way. Since the science shows that homosexuality is not a choice, one solution to the political civil liberties issue is more science research and better science education.
