It took me about 5 minutes to find other academics to call out Peterson on his limited interpretations of creativity not to mention method errors in assuming even for simple creativity tests that test subjects are levelled in their existing abilities. I will leave it to you to look up what that means. I will give you a hint it is related to cultural influences on IQ tests.
However, it is best to simply use Jordan’s own words at 3:31 in this video, "The CAQ is also potently predicted by IQ as expected". CAQ is a creativity score.
Jordan is well known and I even agree with many things he says including the need for creative people to have some other grounding. This is often an issue with high academic performers in physics, chemistry and engineering due to the creativity of their divergent thinking having the potential to make multiple focuses challenging.
He is well known but his ideas are not all universally accepted. Previous to his gender stance he was a known but not exceptional academic.
