Your studies have been proven wrong.

To Quote:

"The most important single contribution to our knowledge of the facts of the
case is to be found in Dr. Franklin P. Mall's paper 'On Several Anatomical
Characters of the Human Brain Said to Vary According to Race and Sex, with
Especial Reference to the Weight of the Frontal Lobe' (Am. J. of Anat., IX.,
p. 1, 1909). Dr. Mall's general conclusion is that there is as yet no
reliable evidence for the variation of anatomical characters with either
race or sex. The belief that the brains of females differ from those of
males has been widely accepted, and has been thought to be conclusive
evidence of the permanent inferiority of the female mind. The points in
which the female brain has been said to be inferior to the male are: (1)
total weight; (2) proportionate weight of the frontal lobe indicated by (a)
actual weighings, and (b) determinations of the position of the central
sulcus; (3) the area of the corpus callosum; (4) the complexity of gyri and
sulci; (5) the conformation of gyri and sulci; and (6) the rate of
development of the cortex in the foetus. Dr. Mall's paper gives a critical
review of the literature of the subject to date, and adds important new
data.

It is now a generally accepted belief that the smaller gross weight of the
female brain has no significance other than that of the smaller average size
of the female. With regard to the other anatomical characters enumerated,
Dr. Mall shows that those observers who have found differences
characteristic of sex have been guilty of serious errors in scientific
procedure. They have based conclusions on too small a series of
observations, have used methods too crude to make anything but large and
constant differences (which they did not obtain) significant, have made
their determinations with a knowledge of the sex of [p. 336] the brain under
consideration, and have even, in some cases, drawn conclusions not justified
by their own data. Those observers who have avoided these errors have found
no differences characteristic of sex. Dr. Mall himself finds none, and is
inclined to believe that they do not exist. The only exception to this
statement is that he finds some evidence of a greater tendency of the male
brain to vary from the normal conformation of gyri and sulci. "

I know you didn't read the materials I offered, you were just waiting for my
reply.

Try reading the entire study, as well as the others.
