Hmm. New research shows that bigger brains don't correlate with intelligence.

Gee, I wonder what the agenda is?

But regardless, Pietschnig and his team showed that there was still a weak association between bigger brains and higher IQs throughout the research, which was independent of sex and age - but they also showed that brain size didn't have much predictive value when it came to measuring intelligence.
Their conclusion is supported by the fact that men consistently have higher brain volumes than women, but that there's no significant difference between the sexes when it comes to IQ tests.
Yup. I could see that coming a mile off.

Of course, it helps when you tweak the IQ tests towards verbal puzzles so that men and women come out roughly the same. Helps even more if you just unapologetically "normalize" the results for sex.
