the term prisoner's' dilemma refers to a game in which
Prisoner's dilemma It is implied that the prisoners will have no opportunity to reward or punish their partner other than the prison sentences they get, and that their decision will not affect their reputation in the future. Because betraying a partner offers a greater reward than cooperating with them, all purely rational self-interested prisoners would betray the other, and so the only possible outcome for two purely rational prisoners is for them to betray each other.[1] The interesting part of this result is that pursuing individual reward logically leads both of the prisoners to betray, when they would get a better reward if they both kept silent. In reality, humans display a systemic bias towards cooperative behavior in this and similar games, much more so than predicted by simple models of "rational" self-interested action.[2][3][4][5] A model based on a different kind of rationality, where people forecast how the game would be played if they formed coalitions and then maximized their forecasts, has been shown to make better predictions of the rate of cooperation in this and similar games, given only the payoffs of the game.[6]
Battle royale game A battle royale game, also spelled battle royal, is a video game genre that blends the survival, exploration and scavenging elements of a survival game with last man standing gameplay. Battle royale games challenge a large number of players, starting with minimal equipment, to search for weapons and armor and eliminate other opponents all while avoiding being trapped outside of a shrinking "safe area", with the winner being the last competitor in the game. The name for the genre is taken from the 2000 Japanese film Battle Royale, which presents a similar theme of a last-man-standing competition in a shrinking play zone.[1][2]
