Arthur Brooks has just done the unthinkable. He’s shattered one of the most enduring myths in both science and society with the precision of a physicist and the insight of a seasoned psychologist.

We’re talking about the belief that our minds peak in our thirties and only decline from there. Well, it turns out this belief isn’t rooted in physics but in flawed psychology. Worse, this myth is holding us back as a species. In this insightful and personal episode, Arthur explains that cognitive decline is not inevitable and that our best, most meaningful work might still be ahead—if we adjust accordingly.

Arthur himself is no stranger to reinvention. From performing with the Barcelona Symphony to leading one of Washington's most influential think tanks, and now teaching at Harvard, he’s experienced multiple intellectual lifetimes. Today, he studies happiness—not as a vague ideal, but as a measurable, achievable, and deeply human pursuit.

Together, we explore why high achievers often feel more depressed after reaching their biggest goals and why lasting fulfillment requires something different altogether. Arthur shares research on emotional temperaments, the science of fluid vs. crystallized intelligence, and the dangers of fame, power, and success. He also gives us a behind-the-scenes look at his collaboration with the Dalai Lama, and why AI might be a surprising ally in extending our cognitive abilities as we age.
