Golf is a poor example. Golf doesn't define who we are, but intelligence really does. Who we are is all tied up in how we think. Very few people are able to socialize well with intellectual inferiors. It's extremely frustating for everyone involved. That's why people tend to seek out like minded individuals socially.
I have to disagree. While no child prodigy, I did learn to read at age 4, currently read about 2K words/min with 95% comprehension, don't own a television, and have read books about the original Constitutional Convention, the 5th Marines, the use of subs during the Philippines campaign of WWII, large chunks of Escoffier, and Plato's Republic in the last few days, along with a regular reserve job.
I get along great with those less educated and able. I have to, they are my airmen and leadership.
I read web synopsis of everything that each is interested in, so we have chit-chat, and toss in a few of the things that I care about.
You don't have to be smart to be good, and you don't have to be good to be smart, but good AND smart is a great combination.
I'm grateful for a mom that taught me to read early, a dad the put me in private school, and teachers that let me reach my limits. I'm also grateful for a USAF that taught me some manners and management skills.
