Comment on Making Rationality General-Interest

My weak definition of rationality: thinking about your own knowledge and beliefs from an outside perspective and updating/changing them if they are not helpful and don't make sense (epistemic); noticing your goals, thinking a bit about how to achieve them, and then doing that on purpose to see if works, while paying attention if it's not working so you can try something else; thinking about and trying to notice the actual consequences of your actions (instrumental).

Short: epistemic=believing things on purpose, instrumental=doing things on purpose for thought-out reasons.

I say weak because this isn't a superpower; you can do it without being amazingly good at that (i.e. if you have an IQ of 90). But you can exercise without being amazingly good at any sport, and you still benefit from it. I think that also stands for basic rationality.

if a person's behavior is seemingly irrational to you, there's still some reason, maybe understood, maybe not understood, maybe misunderstood why the person behaves that way.

In a general sense, yeah. People operate inside causality. But people do things for a reason that they haven't noticed, haven't thought about, and might not agree with if they did think about. For example, Bob might find himself well on the path to alcoholism without realizing that his original, harmless-and-normal-seeming craving for a drink in the evening happened because it helped with his insomnia; a problem that could more healthily be addressed by booking a doctor's appointment. (I pick this example because I recently caught myself in the early stages of this process). But from the inside, it doesn't feel like the brain is fallible, and so even people who've come across research to the contrary feel like their introspection is always correct–let alone people who've never seen those ideas. I don't think the IQ ceiling on understanding and benefiting from "I might be wrong about why I do this" is very high.
