Today, Dr. Killeen explores a learning strategy rooted in an idea from the Roman philosopher Seneca: we learn more deeply when we prepare to teach something to someone else. Research on the Protégé Effect suggests that knowing you will need to explain a concept can push you to study harder, organize your thoughts, and develop a better understanding. Whether you are learning a new clinical procedure or a business concept, choose someone to teach before you begin. Explain what you have learned in simple terms, identify the gaps in your understanding, and go back to fill them. It’s not just to take in more information, but to understand it well enough to teach it.
