Being Smarter Doesn’t Mean You Make Better Decisions

In fact, being smarter might actually lead you to make worse decisions.

Nobel laureate Daniel Kahneman and his scientists measured students on four different points of “cognitive sophistication”.  All four of those measurements were positively correlated with intelligence, meaning that the “more cognitively sophisticated participants showed larger bias blind spots.”  In other words, smarter people are more prone to act without thinking:

In 2 studies, we found replicable bias blind spots with respect to many of the classic cognitive biases studied in the heuristics and biases literature (e.g., Tversky & Kahneman, 1974). Further, we found that none of these bias blind spots were attenuated by measures of cognitive sophistication such as cognitive ability or thinking dispositions related to bias. If anything, a larger bias blind spot was associated with higher cognitive ability.

Something to think about…
