The cognitive differences between men and women
stanmed.stanford.edu
O.k. I'll have to do the remedial and walk you through the socratic dialogue. See above. It's pretty well established that there are observable, physiological differences in the brains between men and women. That's fact is beyond debate at this point. Setting aside the open question as to which differences are relevant and why which for our purposes are beside the point.
The studies which have been done on trans brains are observational. Why are they observational? For the same reason that the studies between mens and womens brains are observational. Because there isn't a blind RCT you can do here. The function of the study is to determine if they are different. That's all. Not the degree or significance of those difference.
Have they detected a difference? Yes. Is it measurable? Yes. How broad is it...for example do we have a No True Scotsman problem that this person is trans and therefore different but this person is not really trans? Yes. But is there a correlation, so that unusually, the brains of MTF trans seem to have female structures? Yes, and vice versa BTW. Would doing a RCT come to a different conclusion? No because the only thing we are doing is observing to see if there's a correlation and then saying "my that's interesting". Is it possible that because of the particular research that only those with an axe to grind are doing it? Yes, but here's the thing...the trans activist community hates this and has actually been working to not do the research. Why? Because it would bolster the case that it's under the disability rubric, and more scarily, might open the door to the same conclusions being drawn for gay individuals.
Furthermore, what other link are people now suggesting (but reluctant to explore) about trans individuals? Autism. Is the trans community happy with that possible link? No...the school shooting thing scares the bejeezus out of them. Why? Because then this isn't a trans issue but instead becomes an autism issue, again putting it under the disability rubric. Do you need a RCT to determine this? No because again it's an observational study in which we are trying to see if there is some correlation, nothing more.
Now take COVID. For your mask argument, an observational study in fact doesn't do it. Why? Because we want to see whether or not there is in fact a noticeable effect from the intervention, yet you and others were quick to trot out all those mannequin studies, despite other observational studies that showed the mask wasn't very effective unless it was an N95. So what's the difference? The difference is you believed in one issue and not another, and that's not science, but religion.
Help me out translator.
Me: "if it's a highly political topic and they didn't blind the researchers, it goes into the dust bin"
My handydandy dad4 translator: "If it's something I disagree with, I'll find the excuse to put it into the dust bin."
Me: "Ah. Thanks translator."
