[Mr. Jeeves]

Bea Campbell, the feminist writer and historian, also questioned the findings. "The distribution of intelligence is much the same for all genders and all races," she said. "Our experience and common sense tells us that the quest to prove one or another biological group is brainier than the other is really a vain exercise."

Leonardo da Vinci. Isaac Newton. Albert Einstein. Rene Descartes. Blaise Pascal. Richard Feynman. J.S Bach. Wolfgang Amadeus Mozart. Edmund Burke. Thomas Jefferson. Just to name a few.

Female equivalents, Ms. Campbell? ;)

It's already been well established that even if there isn't much difference in average intelligence distribution between men and women, men are far more likely to be found at the extremes of the spectrum. More male geniuses than female - but also more male idiots than female. So Ms. Campbell is telling the truth, but missing the point.

Looking at Einstein's brain shows that it is very abnormal. Certain parts of the brain are quite poorly developed.

As for your original statement, that also applies to lefties: More likely to be geniuses, and more likely to be insane or retarded.
