171 - Richard Haier: What Is Human Intelligence?

Richard Haier is Professor Emeritus in the School of Medicine at the University of California, Irvine, where he uses brain imagining and the tools of neuroscience to study learning, memory, and intelligence, and how they relate to brain function and structure. He is the editor-in-chief of the journal Intelligence. In this episode, Robinson and Rich discuss all things human intelligence, ranging from its controversies, the origin and current status of psychometric testing, the relationship between intelligence, brain structure, and function, the predictive power of IQ in career success and other areas, and whether or not it’s possible to increase one’s general intelligence. Rich’s most recent book is the second edition of his guide to neuroscience research and intelligence, The Neuroscience of Intelligence (Cambridge University Press, 2023).
