It's all I do. It's the only way I can understand if my next comment will offend or work as a joke or if I'm posing an interesting topic. It's what makes conversations so draining to an introvert I feel. The more people, the more I have to figure out what I can say to be ok with the group at hand.
As I posted below, there is a difference between observing how different people react to a particular comment (O(n)) and observing how different people react to a particular comment based on who it's from (O(n^2)). I'm mostly trying to question the idea that there's anything quadratic in the number of participants going on here. Are you sure you're saying that the work you do is quadratic?
That's fascinating, thinking about this, I've realised that I only do this when I'm in a conversation with new people or for whatever reason am specifically considering the interplay of what's being said.
Otherwise I have a broad set of heuristics I apply which I adjust as needed.
I never considered that a tendency to do this might have an impact on introversion/extroversion. Something to mull over, thanks!
