Rational agentA rational agent or rational being is a person or entity that always aims to perform optimal actions based on given premises and information. A rational agent can be anything that makes decisions, typically a person, firm, machine, or software. The concept of rational agents can be found in various disciplines such as artificial intelligence, cognitive science, decision theory, economics, ethics, game theory, and the study of practical reason. In reference to economics, rational agent refers to hypothetical consumers and how they make decisions in a free market.
FlipismFlipism, sometimes spelled "flippism", is a pseudophilosophy under which decisions are made by flipping a coin. It originally appeared in the Donald Duck Disney comic "Flip Decision" by Carl Barks, published in 1953. Barks called a practitioner of "flipism" a "flippist". An actual coin is not necessary: dice or another random generator may be used for decision making. Flipism can be seen as a normative decision theory, although it does not fulfill the criteria of rationality.
