... oh! Thanks, that quite clarifies a few things.
Specifically: I notice my rationalization in the presence of obvious fear or disgust, but hadn't been thinking of strong negative affects as "ugh fields." Before your reply, I hadn't verbally noticed that being suddenly interested in marginal details was a good sign of ugh fields, and thus a likely warning sign for rationalization.
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.
