A Canadian study found that if you are queer, you are much more likely than heterosexuals to be left-handed. And the association is stronger for lesbians. In fact, if you are gay, you are 34% more likely to be left handed; if you are lesbians, 91% more likely! Ray Blanchard, one of the authors of the study published in the Psychology Bulletin, says that this is evidence that at least some part of your sexual orientation is genetically or biologically determined, perhaps in the womb.
