You'd think that you need to be a super-genius to become the president, but that's simply not true. Yes, all American presidents are slightly more intelligent than the average mule, but most are right up there with the rest of us. Do you think you're smart enough to become the president? Chances are, you might be.
John Quincy Adams
Coming in first we have the sixth president of the United States of America, John Quincy Adams. He wasn't the most agreeable president, but he did have some important policies that helped our country become what it is now.
Big Head, Big Brain
John Quincy Adams had a notoriously large head, most likely so it could hold his high 175 IQ. That's the highest IQ of any president that has ever lived. John Quincy Adams was a lawyer before and after his presidency, and he helped create the legal systems that we still use to this day.
