Yes. I was mugged at gunpoint, and my initial reaction was to talk about the game theory of the whole situation. Somewhere, somehow, I was able to force down that thought by realizing that they wouldn't be in that situation in the first place if game theory had any space in their thinking, so all I would be doing was increasing my chances of getting killed.

Important context: I'm not brave at all; bravery did not enter the picture in that whole interaction. It was just what I instinctively felt like doing.
