Does Being a Jock Make a Man Gay? Timothy Noah:

‘The theory that ring finger size is destiny has resurfaced.
Faithful Chatterbox readers will recall that a year ago this
column asked, “Does A Short Index Finger Make You Gay?”
Chatterbox cited a study published in Nature (click here to
read a press release on the findings) maintaining that lesbians
tend to have ring fingers that are exceptionally long relative to
their index fingers, apparently because their mothers had high
levels of male hormones in the womb. A less intuitive finding
was that gay men also tended to have long ring fingers, owing,
again, to their mothers having high levels of male hormones in
the womb, though this correlation was more tentative. Mark
Breedlove, the Berkeley psychology professor who authored
the study, used the occasion to suggest that gay men, far from
being feminized men, were in fact hypermasculinized men.
Chatterbox himself struck a rigorously neutral pose, then
stated Chatterbox’s Law of Biological Determinism:
Conservatives believe that genes determine everything
except homosexuality, while liberals believe that genes
determine nothing except homosexuality.’ Slate
