Berserker equilibrium

The idea behind berserker equilibrium is that there is a multiple-
players prisoners' game going on. The game payoffs are set so that, if
you make a move, everyone else will kill you. Your rational play is
not only to refrain from making a move, but to be so quiet no one else
knows you even exist to play the game. So everybody stays silent.

The concept comes from a set of science fiction stories by Fred
Saberhagen: http://bit.ly/fjDtgd. Not from the berserkers, who were
Norse warriors.
