Yes, yes, psych is rife with replication issues, but it is true that smart people are very susceptible to certain biases.
Which makes sense, if you're not stuck on the 50s idealization of the Rational Man (always a man in those times), which is an imbecilic idea.

Some biases are probably natural byproducts of human cognition, so they wouldn't necessarily decrease in more cognitively sophisticated people.
Others are more to the tune of "people aren't very smart," and those are indeed (mostly) negatively correlated with IQ.
