* each | * the "prisoner's dilemma" represents a clash of individual versus group interests | ||
** "dilemma" = a problem for which the solutions all reach a negative outcome | |||
*** as opposed to a "paradox" | |||
**** which is a problem that has no solution, the solution is never-ending, or the solution yields an outcome that negates the original problem | |||
* in the prisoner's dilemma, two prisoners must select between 1) confess to the crime or 2) remain silent | |||
** each is held separately and does not know what the other will choose | |||
* Option 1 choices: | |||
** Prisoner 1 (P1) confesses | |||
** Prisoner 2 (P2) remains silent | |||
** outcome: P1 goes free & P2 serves the worst jail sentence with no chance for parole (no chance to be let out of jail early) | |||
* Option 2 choices | |||
** P1 remains silent | |||
** P2 confesses | |||
** outcome: P2 goes free & P1 serves the worst sentence | |||
* Option 3 choices: | |||
** both confess | |||
** outcome: both serve the worst jail sentence but will be allowed "early parole" (let out early) | |||
* Option 4 choices: | |||
** both remain silent | |||
** outcome: both will face a lesser charge and less jail time | |||
