I recently came across a definition of Rationality that I really enjoy, identify with, and strive for. It was one of those moments when something clicked in my mind. I became explicitly aware of a belief I implicitly carried with me.
Many people think of being rational as similar to being a “robot”. Far from it, being rational is about doing the best we can with what we’ve got. I’ll stop here and let Eliezer Yudkowsky, author of Rationality: From AI to Zombies, take over.
In his book, he writes:
In a Hollywood movie, being “rational” usually means that you’re a stern, hyperintellectual stoic. Think Spock from Star Trek , who “rationally” suppresses his emotions, “rationally” refuses to rely on intuitions or impulses, and is easily dumbfounded and outmaneuvered upon encountering an erratic or “irrational” opponent.
There’s a completely different notion of “rationality” studied by mathematicians, psychologists, and social scientists. Roughly, it’s the idea of doing the best you can with what you’ve got. A rational person, no matter how out of their depth they are, forms the best beliefs they can with the evidence they’ve got. A rational person, no matter how terrible a situation they’re stuck in, makes the best choices they can to improve their odds of success.
Real-world rationality isn’t about ignoring your emotions and intuitions. For a human, rationality often means becoming more self-aware about your feelings, so you can factor them into your decisions.
What do you think of this definition? Did you have a similar one in mind? Or does this change your outlook on Rationality?
