The time when you had to have the highest IQ to be successful is long gone. Traditional methods of measuring IQ have only proved that the system is outdated and that it doesn’t work the best in real life. To be successful beyond books and traditional knowledge, you have to be practical, solution-oriented, know global trends, manage your life and finances well, and know your strengths and weaknesses.

Many successful people of today proved that you don’t need a certain IQ to be a real-life success story. You don’t even need over-the-roof IQ to be a Commander in Chief. Yes, that’s right; you can have an average IQ level and still get to run the country. Let’s see how Presidents of the States did on their IQ testing. Read on to see if President IQ affected any major decision on the global scene.

When he was a boy, Grant had the nickname ‘Useless,’ and he seemed uninterested in school. However, he was interested in West Point, where he graduated and served in the Army. Rumors of corruption dogged his presidency, and he couldn’t do anything to stop a horrible depression that ended in bankruptcy.

Harding is responsible for reducing tax at lower incomes and pushing more government spending. It took him only one year to turn the country’s economy after the post-world War I depression. After his death, it was discovered that hand-chosen cabinet members were highly corrupted. This is the main reason why historians rank his presidency as one of the worst.

23. George W. Bush

IQ score: 124.88

Just like many from his family, Bush was sent to a boarding school. He had a really bumpy experience with educational institutions. However, he did manage to show everyone how a straight-C student can be successful.

There are still unflattering memes, endless jokes, and terrible press about his decision. Kudos to him for trying to bear it all with humor. We don’t know how well he managed to deal with it.

Harry Truman was President No. 33, and he never obtained a college degree – so he one of many who took a nontraditional path of education and career up to presidency level. Since he was blind in one eye, he lied on a vision test to get into the military.
