The present paper describes two studies that investigated incremental predictive value of tolerance and intolerance for uncertainty in predicting creativity. The first study shows significant positive incremental predictive power of tolerance for uncertainty over general intelligence in predicting creativity. The second study reveals a negative relationship between intolerance for uncertainty and creativity with fluid intelligence scores being already accounted for. Overall, tolerance for uncertainty promotes creativity, whereas intolerance for uncertainty impedes it, demonstrating that creativity draws on both intellectual potential and processes of uncertainty acceptance.
