IQ numbers are all bogus. You're measuring success with IQ. It’s reduculous. Of course I can make a person with an IQ of 90 a billionaire. It’s called inheritance. Another way ? Hitting home runs and lots of them. These people have high performance skills and the ability to move mental skills into performance skills is a highly intellectual indevor. High skilled performers can actually change time perception. They can slow time down in their mind. That’s an extremely important intellect capability that can earn one millions of dollars. . You can hire some one to do the business end. I read a lot of science ? Show it. In my world, it’s performance that matters, not BS claims like “ I’m smart.” You want to make a test hard ? Write it in a foreign language or deprive the person being tested of good nutrition.
