Respectfully, after reading the first half of each debater (I confess, it's long enough that I don't plan to finish it.), I think you're dismissing Spelke undeservedly, and I'm not sure why. The results of at least the portion of the debate I read, would incline me to retain my notions of where gender differences are relevant and where they aren't. And the example of testosterone that you give as if it's the only factor determining both prison populations and fortune 500 CEOs seems overly simplistic. Non-white people are also over represented in the prison population, are you going to claim that's not because of social pressures? I don't reject the idea that testosterone is correlated with risk-taking, but the conclusions you draw are leaps, not steps.
I doubt we'll agree until or unless one of us actually makes the issue the core of our scientific investigations. Otherwise, it seems like there's plenty of scientists on both sides of the controversy for either of us to cite. As both the debaters mentioned, it is a very political topic, so divorcing politics from the science isn't something I'd believe whomever I'm discussing it with capable of, and I confess, I don't think it's possible for me either.
I will furthermore point out that the site itself mentions "Both presented scientific evidence with the realization and understanding that there was nothing obvious about how the data was to be interpreted."
So... even they don't think it's obvious.
More to your point, though, both debaters agree there are biological sex differences. The significance of those is what's debatable, and that's where I think you and I differ.
All of the detailed evidence for his position came in the second half of his talk, so if you stopped before then you missed most everything of substance. Also, the citations are included in his slides (which are available the link I provided).
In the concluding discussion part, or in the second half of his initial presentation? I'm in the midst of the concluding discussion at this moment. I guess I am devoted enough to read it all.
LOL. It's fascinating stuff! The second half of his initial presentation is what I meant.
Having read it all now, I think I'll conclude with a quote from Spelke: "I think the only way we can find out [if biological differences make one sex more capable of doing exceptional math] is to do one more experiment. We should allow all of the evidence that men and women have equal cognitive capacity to permeate through society. We should allow people to evaluate children in relation to their actual capacities, rather than one's sense of what their capacities ought to be, given their gender. Then we can see, as those boys and girls grow up, whether different inner voices pull them in different directions. I don't know what the findings of that experiment will be. But I do hope that some future generation of children gets to find out. "
