Maybe you're a special case, but most people are better with some distance to think about the big picture of what they're doing. It's why people like the former Presidents we mentioned waited two days to compose such messages. I spend a lot of time on this stuff and still find that I always have a better approach when waiting.

It's also the point to emphasize that waiting to have a real conversation about it is best no matter how polished you are. You can be a perfect communicator, and taking the time to hear their side, go over examples, and talk about next steps ensures the feedback is actually meaningful (i.e.- leads to positive change). Firing that off a note in a "Real Time Feedback" system does none of that.

I'll bet on the leader that picks their moments for feedback and is deliberate and detailed, over someone reliant on their exact eloquence in the moment every time.
