+[quantifying the two-type effect:
+GD occupations in study 2
+gay men are at .48 (.14); straight women at .36 (.13); straight men at .68 (.12)
+that's d=–1.61 between gay and straight men
+a gay man only needs to be 1 standard deviation (.48-.36 = 0.12) more feminine than average to be as feminine as a straight women
+whereas a straight man needs to be (.68-.36 = 0.32) 0.32/0.12=2.67 more feminine than average to be as feminine as a straight woman—that's rarer, but not impossible
+
+In percentile terms, 1-norm.cdf(1) = 0.15 of gay men are as feminine as a woman
+whereas 1-norm.cdf(2.67) = 0.003 of straight men are
+that's a likelihood ratio of 50 ... but the prior is not that far from 50:1 in the other direction! They cancel out!!]
