# Rationalizability or Nash equilibrium

In the 'chicken' game, (stop,go) and (go, stop) are the two pure strategy Nash equilibrium profiles. If the game is played once, does it make more sense to use the rationalizability solution concept? The way I think of it is, that if we can't correctly predict the rival's action, then we might end up not coordinating. Thus, although Nash equilibrium gives a sharper prediction, rationalizability is more realistic to use, given that crashes do happen!

Any thoughts?
