I read somewhere that the higher the IQ the more you are likely to be creative and the people with lower IQs do not show the same ability in creativity. Then another source, this one a more recent study, said that IQ and creativity is linked, but at a certain point (around 120 IQ), there stopped being a correlation. I'm curious about this since there are existed highly creative people with high IQs, then there was people who with average and even below average IQs that showed same levels of creativity.

Is there a correlation? Is there a breakpoint at some level and it depends more on other factors?
