Smiddy - Lets settle this half-truth of women's brains versus men's brains shall we ?
First of all millions of IQ tests given have shown women to be every bit as smart as men. A woman with an IQ of 150 is a genius, and a man with an IQ of 85 is an idiot, no matter what size his weaker brain is.
Second women's brains are denser than mens with less unused space filled with liquid, which means men have more gaps in their brains, again overall size does not help men when portions are virtually empty.
Third Women have more white matter in their brains, speed of data processing occurs is white matter, not gray matter, men have 6.5 times of the slower gray matter.
Women have about 10 times more white matter than men do [source: Carey]. This difference may account for differences in how men and women think. Men seem to think with their gray matter, which is full of active neurons. Women think with the white matter, which consists more of connections between the neurons. In this way, a woman's brain is a bit more complicated in setup, but those connections may allow a woman's brain to work faster than a man's [source: Hotz].
Some women even have as many as 12 percent more neurons than men do [source: Hotz]. In studying women's brains, psychologist Sandra Witelson found that those neurons were most densely crowded on certain layers of the cortex, namely the ones responsible for signals coming in and out of the brain. This, Witelson believed, may be one reason why women tend to score higher on tests that involve language and communication, and she came to believe that these differences were present from birth
