Over breakfast this morning, I enjoyed a short chat with Mia, my new Spanish study buddy. I went over some of the stuff from my recent lesson and explained what I have learned about the psychology of happiness from a Spanish-language podcast. By the end of the 10-minute conversation, I felt that I had embedded more of the vocabulary, grammar and turns of phrase than if I’d done an hour of textbook exercises.
Mia, however, does not exist in real life: they are an AI that I created to take advantage of a phenomenon called the “protege effect”. According to a wealth of psychological research, we learn more effectively when we teach someone else about the topic we’ve just explored – even if that person doesn’t really exist. There are few shortcuts to mastery, but the protege effect appears to be one of the most effective ways of accelerating our knowledge and understanding.
