In my experience, it's either hard to articulate or it's something I wouldn't say to them like "you came across as very arrogant." Not the same thing but imagine dating scenarios. I've had plenty of situations where there were no red flags and also I couldn't have filled out a questionnaire about why I didn't "click" with a person.

That's not always the case. "Your writing sample was poor" so take a writing class. But I'd say that has been the minority and I could name one mistake where I assumed that was a flaw we could fix.
