You just cannot say that there's no relationship between brain size and
"intelligence" as measured by relatively non-politicized tests like TIMSS or
GRE. When J Phillipe Rushton collected all the brain size measurements, he
correlated them with IQ tests rather than GRE or TIMSS. The data STILL
correlated, but the correlation is much higher between brain size and GRE
scores, which is something he never did (unless he did it recently).
Having just correlated TIMSS by race and sex, I can tell you that the TIMSS
scores support precisely the correlation of GRE scores by race and sex with
brain size by race and sex. The fact that his brain size data correlates so
well with GRE scores can't be just an accident, and the TIMSS correlation
So the 29% of the men and 43% of women on the Gallup Poll who stated that
they believe that women are more intelligent than men, and the 40% of men
and 40% of women who stated that they believe that men and women are equally
intelligent, are plain flat wrong. They've been seriously misled. Or,
they're just plain STUPID.
This leaves us with only 28% of men and only 14% of women who know the truth
This disinformation campaign began with Wechsler during WWII when he threw
out 94% of the questions so he could create a test where men and women had
"When Wechsler was developing his IQ test, he found that out of 105 tests
assessing skills in solving maze-puzzles, involving the most heterogeneous
populations throughout the world, 99 showed an incontrovertible male
superiority. (Wechsler resolved this type of problem by eliminating all
those tests that resulted in findings of significant sex differences.)"

And Gallup is propagating this LIE by LYING about their very own data:
>>>Neither sex is most likely to be described by the terms "intelligent,"
"easy-going," and "ambitious."
This is bunk. Gallup's very own data shows that men are 1.4 times more
likely than women to believe that men are more ambitious, 1.2 times more
likely to believe that men are more easy-going, and twice as likely to
believe that men are more intelligent, but women are 1.1 times more likely
to believe that women are more easy-going, 1.3 times more likely that women
are more ambitious, and 1.5 times more likely to believe that women are more
iow, this statement is a LIE, pure and simple.
Not only does Gallup LIE about actual differences in intelligence between
races and sex, but they LIE about what people *think* about these
