Trump has a successful business pattern and had a ton of start up capital from his dad.
He isn’t dumb, but he isn’t 150+ IQ like he claims.
Well, he's a $150,000,000 IQ, if you see what I mean. What does IQ even mean? Just marks you made on a piece of paper.
How can you tell?
I have not heard him say anything about his IQ. I have high IQ, and so do most people I know (amazing how we all end up working together). Among all of these extremely smart people, I do not know of a single one who could have accomplished what Trump has.
It takes a lot of skills to accomplish what Trump has. The ability to negotiate, to manage people, to network, and so forth, at extremely high levels, is rare. That is why there are so few mega-rich: most people don't have the requisite skill combination.
