Slow down a bit.  You imply you're addressing the issue of "Why
compare Einstein's brain to male brains and not female?".  But that's
not exactly the issue Peter raised, and in this context the
substitution is a bit unfair.  He pointed out that the effect is "to
ignore size and concentrate on structure", and your argument doesn't
refute that.

And certainly it's reasonable to compare against a range of sample
classes: all human brains, male human brains, physicists' brains.  The
insistent focus on never using the wider comparison tends to support
Peter's point in a backhanded way.  You could argue that it would be
like comparing against monkey brains, which we know simply aren't as
capable as human brains, but I don't think you want to make that
analogy.

Now, be fair.  You know there are severe political and ideological
pressures against publishing anything like that.  Scientists like
Suzanne Steinmetz have received death threats against themselves and
their children simply for publishing results that went against
Feminist interests.  At the very least, anyone who published about
anti-male bias in IQ tests could look forward to great difficulty ever
getting another research grant.  Anyone who reviewed it favorably
would be taking a political chance too.  So you can't just assume that
such information would make its way into peer-reviewed journals.

But the *information* is out there.  Credit to Leonardo
