Flipism

Flipism, sometimes written as "Flippism," is a pseudophilosophy under which all decisions are made by flipping a coin. It originally appeared in the Disney comic " Flip Decision" by Carl Barks, published in 1953. Barks called a practitioner of "Flipism" a "Flippist" (with two P's).

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.
