Cousin Marriage OK by Science

By Brandon Keim

In an age of sexual liberation, marriage between cousins remains taboo, at least in the United States — and from a scientific perspective, laws against the unions are a socially legitimized form of genetic and sexual discrimination.

That argument, raised Monday in an editorial in Public Library of Science Biology, may turn the stomachs of people raised to disapprove of any form of incest. But dispassioned analysis suggests that cousin marriage is no more troubling than childbearing by middle-aged women.

"Women over the age of 40 are not prevented from childbearing, nor is anyone suggesting they should be, despite an equivalent risk of birth defects," write zoologists Hamish Spencer and Diane Paul. Bans against cousin marriage, they say, should be repealed, "because neither the scientific nor social assumptions that informed them are any longer defensible."

Thirty-one states outlaw marriage between first cousins, making the United States the only developed country in which the practice is regularly banned. Most were passed in the Civil War's aftermath — not, say Spencer and Paul, to reduce the chance of defects caused by combinations of deleterious genes, but as part of a radical expansion of government authority over private lives.

"Unlike the situation in Britain and much of Europe, cousin marriage in the U.S. was associated not with the aristocracy and upper middle class but with much easier targets: immigrants and the rural poor," they write.

But their argument is far from consensus: in Forbidden Relatives: The American Myth of Cousin Marriage, Kansas State University anthropologist Martin Ottenheimer argues that the bans were driven by now-discredited 19th century research on birth defects among children born to first cousins.

Whatever their motivations, the laws are not supported by science. According to the National Society of Genetic Counselors, birth defects are 2 to 3 percent more common in children born to first cousins than among the general population — a real risk, but not enough to justify the bans.

"It's a form of discrimination that nobody talks about. People worry about not getting health insurance — but saying that someone shouldn't marry based on how they're related, when there's no known harm, to me is a form of discrimination," said Robin Bennett, a University of Washington genetic counselor who led the NSGC study.

Precise statistics on cousin-union frequency in the United States are hard to come by, she said, but discrimination and ignorance have serious consequences.

"I'm aware of people who have been afraid to tell people that they're in love with their cousins, who've become pregnant and potentially terminated a pregnancy based on false information," said Bennett. "Or they didn't marry the person they loved because of their concerns."

"The laws against cousin marriage are archaic, outdated and counterproductive," said Ottenheimer.

Repealing these laws doesn't seem likely in the near future: Gay marriage remains a more pressing issue. But anyone who wants to fight for cousin marriage won't have to fight against science.

"Ultimately it's a political question about what you allow individuals to do, and what that says about the structure of society," said Spencer.

What can I say? We all have hot cousins. :)

Here in Quebec Uncles and Aunts can marry nephews and neices. It probably never happens, but I'm glad the government doesn't interfere.

some parts of the world it is perfectly fine to marry your cousin, i know some people that are married to their cousin, usually happens in Africa and Asia

I think for Chinese, 2nd cousins are encouraged to marry to bring the family closer.

2nd cousins as in, the fathers are not brothers.

But i dont wanna marry my cousin! No!

 In a country where you can only have once child? (2nd) cousins are not possible then....If I don't miss something.

It's legal in the UK but generally considered a bit weird. I had no idea it was illegal in the US. You sure have a lot of random laws.

@konnichiwa That law only applies in certain parts of China.

Makes sense to me.

We had two bags of grass, seventy-five pellets of mescaline, five sheets of high-powered blotter acid, a salt shaker half full of cocaine, a whole galaxy of multi-colored uppers, downers, screamers, laughers…Also a quart of tequila, a quart of rum, a case of beer, a pint of raw ether and two dozen amyls.  The only thing that really worried me was the ether.  There is nothing in the world more helpless and irresponsible and depraved than a man in the depths of an ether binge. –Raoul Duke

It is hard to shed anything but crocodile tears over White House speechwriter Patrick Buchanan's tragic analysis of the Nixon debacle. "It's like Sisyphus," he said. "We rolled the rock all the way up the mountain...and it rolled right back down on us...."  Neither Sisyphus nor the commander of the Light Brigade nor Pat Buchanan had the time or any real inclination to question what they were doing...a martyr, to the bitter end, to a "flawed" cause and a narrow, atavistic concept of conservative politics that has done more damage to itself and the country in less than six years than its liberal enemies could have done in two or three decades. -Hunter S. Thompson

Second cousins are the kids of your (first) cousins (I'm pretty sure). Not the second born cousin.

I had a few neices that had a crush on me. It felt a little werid but good at the same time. Knowing they like me, I kind of flirt with them a little, just to tease. ~_n

Age differences in my family are weird also. I have neices that are my age and older than me.
