You seem to be ignoring Peter's original point about the differences in
average size between male and female brains.  To be specific, it's of much
concern to his point that the male brain contains an average of 3 1/2
billion or 18% more brain cells than the female brain, and that their sizes
are correspondingly different.

The purpose of this thread is what you're claiming is "pointless".  It's
useful to include known outliers in the data if they're not unique in some
way, but because it's known that "Einstein's papers" were written one or two
decades earlier in Europe by other men whom he never cited, using his brain
size as a control sample is exactly the wrong thing to do.  He's a member of
the race which has one of the smallest brain sizes as well.

Peter will get closer to the truth if he sticks to the averages across race
and sex, particularly if the standard deviations at are correct.
