Making Sense with Sam Harris
* Fluid vs Crystallized Intelligence?*
Fluid intelligence refers to the ability to solve problems, innovate, and learn new skills, which tends to peak in the late thirties or early forties and then decline. On the other hand, crystallized intelligence is based on knowledge, wisdom, pattern recognition, and vocabulary, and continues to increase through the forties and fifties, remaining high in the seventies and eighties. Careers that rely on fluid intelligence, like poetry, tend to have a half-life around age forty, while careers that rely on crystallized intelligence, like history, reach their halfway point around age sixty-five. The goal is to transition from the peak of fluid intelligence to the increasing crystallized intelligence in one's forties and fifties by manifesting skills and knowledge in different ways.
