If lots of people have an error in their map, and this error causes many of them to make a bad decision, then pointing out this error is rationality-enhancing.
No, that makes it a useful factoid. I don’t consider my personal rationality enhanced whenever I learn a new fact, even if it is useful, unless it will reliably improve my ability to distinguish true beliefs from false ones in the future.
