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.
