I also like how JSO is willing to use a social scientific observational study to make his point in this thread but questions the validity of any climate change theory that isn't able to provide unquestioned, definitive proof of its assertions.
I indicated in the opening post of this thread that the answers to questions pertaining to whether or not this study shows that there is some adverse effect of homosexual parenting is "no" because it is an observational study. That is the same thing I have said in the past about the climate change thing. I said that the big point is that those on the "Focus on the Family" side now have a study they can refer to.
I read the whole paper last night and I can say that the International Panel on Climate Change (IPCC) did something in its physical science basis report that I like better than what the author of this report did. The IPCC conceded that unequivocal "attribution" of cause and effect is not possible without controlled experiments which are not possible. The author of this report did say that this particular study does not show cause and effect. But he appears to think that one can show cause and effect with an observational study as he wrote this:
Although the NFSS offers strong support for the notion that there are significant differences among young adults that correspond closely to the parental behavior,family structures,and household experiences during their youth, I have not and will not speculate here on causality, in part because the data are not optimally designed to do so, and because the causal reckoning for so many different types of outcomes is well beyond what an overview manuscript like this one could ever pur-port to accomplish. Focused (and more complex) analyses of unique outcomes, drawing upon idiosyncratic, domain-specificconceptual models, is recommended for scholars who wish to more closely assess the functions that the number, gender,and sexual decision-making of parents may play in young adults’ lives. I am thus not suggesting that growing up with a lesbian mother or gay father causes suboptimal outcomes because of the sexual orientation or sexual behavior of the parent; rather,my point is more modest: the groups display numerous, notable distinctions, especially when compared with young adults whose biological mother and father remain married.
I think it would have been better for him to just say that an observational study can't be used to infer cause and effect.
