The cognitive biases you carry are independent of your intelligence and of one another.

From Scott Alexander.

Individual Differences In Cognitive Biases – Evidence Against The One-Factor Theory Of Rationality. Unlike IQ where lots of different kinds of intelligence tests correlate with each other pretty well, rationality does not appear to have a general factor and people who do well in avoiding one kind of cognitive bias aren’t much more likely to do well at avoiding another. Doesn’t look like a super well-cited paper, which makes me wonder whether Stanovich et al have a response to this.

From the paper's abstract:

In this paper we seek to gain an improved understanding of the structure of cognitive biases and their relationship with measures of intelligence and relevant non-cognitive constructs. We report on the outcomes of a study based on a heterogeneous set of seven cognitive biases — anchoring effect, belief bias, overconfidence bias, hindsight bias, base rate neglect, outcome bias and sunk cost effect.

This pattern of results suggests that a major part of the reliable variance of cognitive bias tasks is unique, and implies that a one-factor model of rational behavior is not plausible.

I have often wondered whether anyone has prepared a mapping of the type and prevalence of biases to which populations might be prone.
