Well, given that such a statement is impossible, it certainly wouldn't affect mine.
Can't have correlation with categorical variables. Never mind that you did not mention what exactly was correlated.
I think I got your meaning though, but such a study would not be convincing unless you were able to prove that its not the environment. Hell, you could have simply proved that adopted kids have a higher chance of being homosexual.
Getting very meaningful results is damn near impossible in this area of the social sciences because of the inherent variability within the human race. Even with identical twins, you can't account for enough variables. In theory, you could raise the sample size to the point that other variables are drowned out, but that would probably take tens of thousands of subjects.
Yes, I didn't want to write at length to explain exactly what was being counted. You caught my meaning: If one male identical twin is gay, the chance that his twin, raised in a different environment, is also gay, is much higher than in the population at large.
Bailey and Pillard (1991): occurrence of homosexuality among brothers
- 52% of identical (monozygotic) twins of homosexual men were likewise homosexual
This implies that it is likely that male homosexuality has a strong biological component.
And no, adopted children are no more likely than non-adopted children to be homosexual, so that's not it. Brothers of adopted, heterosexual, identical twins are NOT more likely to be homosexual than the incidence in the population at large.
In any case, none of that was my point. My point was that tagent_smith was mistaken in his prediction. Since this data seemed important to him, I wondered if the fact that he was wrong would have any impact on his opinion. My prediction is that it will not.
