Also, that most IQ tests measure the type of intelligence that best correlates with academic achievement; types of intelligence that relate to other forms of achievement are not necessarily measured.
My neighbor in my new home in rural Kentucky only has an eight grade education, but he is one smart cookie. And his intelligence serves him very well here.
One of the great benefits of higher education, to me, is demonstrated in the concept of “music appreciation”. The more you know about the creation of music, the more you enjoy it. The more you know about how things work, the more you enjoy the world that contains those items. The more you know how to deal with them. The more accurately you can anticipate their future actions and adjust your life course accordingly.
But you don’t need to go to college to know how to drive over that shiny spot in the road in the dead of winter. And this touches on why I gained so much value back in 1970 from spinning donuts in the snow of the school parking lot. :-)
On a similar tack, I sometimes tell groups to which I speak that if I was caught in a desert, I would certainly prefer a Kalahari Desert Bushman for a guide over a cultural anthropologist from Columbia. (I would also, inter alia, have more respect for the integrity of the Bushman!)
