I personally rarely find that to be evidence of rationalization; instead it generally means that I know various disjunctive supporting arguments but am loth to present any individual one for fear of it being interpreted as my only or strongest argument.
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.
