An interesting phenomenon that has been proven true many times over but seems so counterintuitive it is hard to believe. When asked to guess the weight of a cow or the number of jelly beans in a jar, often the average of all the guesses is extremely close to the correct answer. Even more accurate than many “experts'” guesses. This is an interesting case in which we can prove something true mathematically but still have a hard time believing. Overall great podcast.
