In this episode Curt Jaimungal talks with neuroscientist Richard Haier about the science of intelligence, the g‑factor, and how brain efficiency relates to IQ. They examine controversies such as The Bell Curve, discuss genetic and environmental influences, and explore interventions from brain training to neuromodulation.
