This is all incorrect information. Einstein never had his IQ tested. It's just presumption based on achievement - nothing more. That said, he came from an ethnic group who had very high IQs. My late father and brother had IQs of 185. That's tested by education authorities. It's genetic. One inherits it from one's parents.
Kim Kardashian's IQ is in the range of 95 to 100. She failed her first year law exam twice and passed the third time. The Kardashians are extremely average and a little bit below average. People with IQ exams of 190 don't fail minor exams. They especially don't fail them twice.

The only authentic IQ tests have to be done by education, government, Mensa, and industrial psychologists. Tests on the web are not authentic. And in order to determine someone's IQ, one actually has to sit the test.
Donald Trump is beyond stupid. He certainly does not have an IQ of 156 as claimed by the site.
According to Finland who went out to study and test successful business owners, their average IQ is 115 (average IQ ranges from 85 to 115). There is not a degree in the world that cannot be done with an IQ of 119. They're not difficult, and they certainly aren't difficult for someone who is said to have an IQ of 190.
People are not cheated by people with high IQ. They are cheated by dishonest people, and there is a correlation between high IQ people and honesty. There is also a correlation between stupidity and criminality. Most people get cheated because they want to believe something.
The people with the least people in prison are atheists, and studies show that they are the most intelligent group. The people with the most people in prison are Christians. The correlation between benevolence and IQ is that they are the smartest people.
You know all those romantic scammers? The one's who cheat lonely people? The lonely people believe them because they are desperate for affection. They want to believe it. The scammers? Average IQ in Nigeria is 77 (well, in Africa, actually). And most of these scammers come from those countries.
My late father knew Einstein by the way. They were at the same college in Berlin...
