This comes as no surprise: A national survey found that individuals don't actually have to be smart to be rich. In fact, people with below-average IQ test scores can be just as wealthy as brainiacs. According to the study, it's more about attitude than smarts.

The study's author Jay Zagorsky, an economist at Ohio State University's Center for Human Resource Research, says that it's up to each person to have a positive attitude and want to save up money and build up his or her wealth, and each and every one of us can do it regardless of our IQ.

Indeed, intelligence positively affects income as people with higher IQ tend to have higher education leading to higher paying careers. Basically, individuals with higher IQ scores earned higher incomes with each additional IQ point associated with an income boost of $202 to $616 each year.

But, the higher income didn't make them more wealthy as IQ score had no impact on wealth. In fact, highly intelligent people actually have financial difficulties, maxing out credit cards and missing bill payments, making them less wealthy. The lowest financial distress was found around the average IQ score.
