Using this reasoning, both prisoners will choose "confess", even though it is not best result.

Using this reasoning, both prisoners will choose "confess" as providing the best outcome ''for themselves'' in all circumstances, even though it is not best result ''for the group''.

The strategy "confess" is a strictly [[dominant strategy]]: The choice of the Prisoner B does not change the way Prisoner A will act. The "confess/confess" scenario is also the only [[Nash equilibrium]] in this problem.
