I'm trying to describe a situation that you face when both you and another person must make a choice, but the outcome of both choices depends on the other person's choices, leading you and the other to wait in order to try to guess the other's course of action.
For instance, when you're going one way on the sidewalk, and someone else is coming your way, a collision would happen should neither of you change path.
Now the problem is who should do it, and in which direction ? It is quite common that you and the other would try and sidestep in the same direction at the same time for a while in unfortunate synchronization.
So I'm looking for a word that can describe the situation, or the behaviour of people facing this situation.
I know there is such a word, at least in French (my native language), because a teacher introduced the notion (using the very same example I gave) during his lecture. Unfortunately, I can't remember the word (hence my asking), but it was in the context of Speech Act theory. I appreciate the expressive power of this word and would like to rediscover it....
