sorry, but all i see are assertions, no empirical research.

quite the spread. How much variablility was explained by age and how

it's also impossible to prove that there's any relationship to a
putative difference in the number of brain cells.
just where did the samples come from where these numbers were generated?

i suppose there's a reference there somewhere.

assuming the numbers are correct. and that's quite the assumption.

the brain cells were counted how?

What does all of this have to do with the assertion that there is a
gender bias in IQ testing? Mattarazzo (1972 *Weschler's Measurement and
Appraisal of Adult Intelligence*) reviewd the then current literature
quite extensively (p 352 ff). He cited numerous studies that attempted
to demonstrate such a difference and failed to do so.
