'Cause after all, he's just a vasopressin receptor
To a recent article about metamaterials ("Chinese boffins crack invisible-shed problem", 9/3/2008), Lewis Page at The Register added this disclaimer:
WARNING: Habitual use of our science coverage may harm your baby and others around you. Such use has been linked to incidence of the King's Evil and is thought to contribute to global warming, entropy, substance abuse, terrorism, hair loss, volcanoes, orbital decay, intellectual languor and decline of moral standards in team sport.
Unfortunately, this warning is not yet required by the FCC. But if you're in the market for some entropy, intellectual languor and decline of moral standards in team sport, it'll be hard to top the past week's reports about the "monogamy gene" (AKA the "infidelity gene", the "divorce gene", etc.). A small sample of the headlines (with linked stories):
"Is monogamy genetic?"; "Baby, my genes made me do it"; "Some men carry 'commitment-phobia' gene"; "Is Lover Boy a Louse? It May Be Genetic"; "Infidelity: It's All In the The Genes"; "Would you abort George Clooney?"; "Study: For men, genetics might untie marital bonds"; "Marriage Woes? Husband's Genes May Be At Fault"; "Marriage problems? Husband's genes may be to blame"; "Study Finds Fear of Commitment May Be in a Man's Genes"; "Commitment phobes can blame genes: A man's reluctance to marry may be down to a genetic 'flaw', say researchers"; "Marital crisis? Blame it on male genes"; "'Bonding Gene' Could Help Men Stay Married"; "Divorce gene linked to relationship troubles"; "Scientists Discover the Monogamy Gene"; "Gene Variant Holds The Key To A Long And Happy Marriage"; etc., etc.
You can pretty much guess how this is going to turn out. The researchers found a small effect — the biggest result was a 5% difference in group means on a "Partner Bonding Scale", for 41 (out of 1,104) guys who were homozygotic for one of the 11 alleles examined at one of three loci. There was a lot of overlap in the distributions — the biggest effect size was about 0.38 — and most of the differences and effect sizes were much smaller. And because it was a twin study, the small group of subjects with the genetic pattern associated with the biggest difference was effectively even smaller, and may well have shared a large number of other cultural and genetic traits.
But most of the media coverage presented this as another triumph of contemporary genetic Calvinism: the fate of our relationships is written at birth in the book of our genes.
