How do you notice when you're rationalizing? Like, what *actually* tips you off, in real life?
I've listed my cues below; please add your own (one idea per comment), and upvote the comments that you either: (a) use; or (b) will now try using.
I'll be using this list in a trial rationality seminar on Wednesday; it also sounds useful in general.
I noticed that there is a certain perfectly rational process that can feel a lot like rationalization from the inside:
Suppose I were to present you with plans for a perpetual motion machine. You would then engage in a process that looks a lot like rationalization to explain why my plan can't work as advertised.
This is of course perfectly rational since the probability that my proposal would actually work is tiny. However, this example does leave me wondering how to separate rationalization from rationality possibly with excessively strong priors.
What's happening there, I think, is that you have received a piece of evidence ("this guy's claims to have designed a perpetual motion machine") and you, upon processing that information, slightly increase your probability that perpetual motion machines are plausible and highly increase your probability that he's lying or joking or ignorant. Then you seek to test that new hypothesis: you search for flaws in the blueprints first because your beliefs say you have the highest likelihood of finding new evidence if you do so, and you would think it m...
