Octo, I don't find a link for adding my comments to the blog at http://octogalore.blogspot.com/2008/11/introducing-larry-summers.htmlso I'll pull out some quotes from there and comment here.
Octagalore said: "as you can tell from the post, I am not attempting to refute Summers that his 50%/33% stat is persistent in testing. I am stating that his assumption that one can casually remove socialization n from being a probable key factor is completely undocumented [....]"
I agree that the difference in testing could probably be traced back to socialization, and that socialization is much more important than would appear from his talk.
Where you leave out "at the top end" you almost totally misrepresent Summers' statements. Here is one place you got it almost* right -- "believes at the upper end, there are more men for reasons to do predominantly with motivation and aptitude. His "apology" creatively didn't refute that."
His "apology" says: "I did not say, and I do not believe, that girls are intellectually less able than boys, or that women lack the ability to succeed at the highest levels of science. As the careers of a great many distinguished women scientists make plain, the human potential to excel in science is not somehow the province of one gender or another. It is a capacity shared by girls and boys, by women and men [....]"
If there is "creatively" no contradiction between the "more men" statement and the "apology", then we should take the "apology" as the true statement on the popular level -- instead of inventing popular level statements that contradict the "apology."
But please do remember that even so, his stated purpose was to provoke refutation of the aptitude theory!
*Almost right, because motivation is only one part of his first factor (lifestyle/high-powered job). Even with equal motivation, a woman who has children is hampered by need for childcare, difficulty in catching up after maternity leave, etc.
You say: "He’s being chastised for positing an uncorroborated theory as the second most important factor."
Summers said that aptitude/testing results as the second most important factor in disparity of tenure. You've admitted the difference in the testing results. I don't recall Summers stating any theory about the cause of the testing results (or of the difference in aptitude that the testing results presumably show).
Octogalore said... The variance measurement is not the root cause but is the current testing result. It is not a theory, and I'm not disputing it, but it doesn't yield us any info as to its cause. The theory Summers is promulgating is that lower female innate aptitude is the second most critical reason behind the result. December 1, 2008 6:09 PM
Summers guessed that lack of availability of high-end females, in line with the testing result, was the second most important reason behind the tenure disparity. I do not recall him offering a theory as to the cause of the testing result -- certainly not a theory including a first and second most critical reason for the testing result.
Your phrase "lower female innate aptitude" does not occur in his "working lunch" talk. What actual quote are you basing that on?
