The Raven data actually suggests that the entire male curve is shifted right (men dominate the genuises and women dominate the retarded), but women make up for that with increased height in the middle.
Other data sets show the men having a broader distribution, to both ends, but Raven is actually one of the best measures.
I feel like there's a hands-on/theoretical divide to intelligence too.
Case in point: 1st person is really good at sailing a boat,knowing what the boat is going to do with the wind coming from a certain direction and sail set one way.
2nd person can't steer the boat but can figure out all the ropes and pulleys of the sails to replace them with new ropes & pulleys which 1st person can't do.
That's the various applications of intelligence, but they all spring from the same well.
I picked a Seal, in my example, as their average IQ is 112, which is nearly 1SD, and that puts them in the 78th percentile.
Nobody thinks of them, when they think of smart people, but a dumb Seal would be too easy to kill.
