When you find yourself in a disagreement with someone - whether you are discussing politics or football - you probably tend to view the experience as a waste of time. Humans are stubborn creatures because we need to validate our own egos. That means no one wants to "give in." We all want to "win" the argument.
However, as Julia Galef, President of the Center for Applied Rationality, demonstrates in today's lesson, if you are simply out to "win" an argument and validate your ego, you really aren't winning much of anything. You are actually missing out on an opportunity for learning and personal growth.
Remember that arguments are not like duels. At the end of the duel if it turns out that your opponent has a bigger and better weapon than yours, Galef says, once you lose that duel you then get a copy of that bigger, better weapon, which you can then use to win duels with other people about that issue in the future.
