I'm missing something basic, here: If cognitive sophistication does attenuate other biases, how can they tell that the cognitively sophisticated believe themselves less biased than the average person to the point of being biased in that belief, rather than merely to the point of being correct?
VincentYu has it right. They 1) used biases that had previously been shown to be uncorrelated with intelligence and 2) checked and confirmed that the biases actually were uncorrelated with intelligence in their sample.
A New Yorker article on cognitive biases was on the reddit front page in the last day. It seems like a good opportunity to discuss what the article got right, what it didn't, how reddit reacted, and how one might better publicize the topic in the future.
