zero-sum game

in game theory, a type of game in which the players’ gains and losses add up to zero. The total amount of resources available to the participants is fixed, and therefore one player’s gain necessarily entails the others’ loss. The term is used particularly in analyses of bargaining and economic behavior but is sometimes also used in other sociocultural contexts (e.g., politics). Compare non-zero-sum game.

method of residues

method of residues

the fourth of the five canons of empirical science laid down by John Stuart Mill. It is meant to establish sufficient conditions for a phenomenon through the elimination of alternative potential causes on the basis of previous experiments or already known laws. For example, if the phenomena E1 and E2 occur together having antecedents C1 and C2, and if it is known by prior research or established law that C1 cannot cause E2 but causes E1, one may conclude that C2 is the cause of E2. Also called residue method.
