Stanovich (2009) argues that standard IQ tests measure certain analytical abilities but miss broader dimensions of rational thought such as recognizing cognitive biases and probabilistic reasoning.

Summary

A high IQ score does not guarantee that someone actually reasons well in practice. A person can excel at the analytical puzzles that IQ tests measure while still being systematically tripped up by cognitive biases and poor probabilistic judgment, so treating raw intelligence as a stand-in for rational competence is a flawed assumption.
