Episode description
Ness and Jeff dig into the history and science of IQ testing — where it came from, how it works, what it measures, and what the data shows about cognitive differences across individuals and populations. We cover the g factor, the Flynn Effect, heritability, the relationship between IQ and standardized tests like the SAT and LSAT, and the policy implications of what the research shows.
