Why the best learners talk to themselves | Tania Lombrozo
Oct 20, 2026 · 18m
Summary
Cognitive scientist Tanya Lombroso argues that in an age of information overload, the most effective way to learn is by thinking rather than immediately seeking external data. She introduces the concept of "learning by thinking," which involves explaining concepts to yourself to transform existing knowledge and identify gaps in understanding. By acting as your own "rubber duck," you can overcome the illusion of explanatory depth and determine precisely what new information you need to acquire.
