fact there are types of satire that are not meant to be "funny" at all. Conversely, not all humour, even on such topics as politics, religion or art is necessarily "satirical", even when it uses the satirical tools of irony, parody, and burlesque. Even light-hearted satire has a serious "after-taste": the organizers of the Ig Nobel Prize describe this as "first make people laugh, and then make them think". Social and psychological functions Satire and irony in some cases have been regarded as the most effective source to understand a society, the oldest form of social study. They provide the keenest insights into a group's collective psyche, reveal its deepest values and tastes, and the society's structures of power. Some authors have regarded satire as superior to non-comic and non-artistic disciplines like history or anthropology. In a prominent example from ancient Greece, philosopher Plato, when asked by a friend for a book to understand Athenian society, referred him to the plays of Aristophanes.

Karl Kraus set in the history of satire a prominent example of a satirist role as confronting public discourse. For its nature and social role, satire has enjoyed in many societies a special freedom license to mock prominent individuals and institutions. The satiric impulse, and its ritualized expressions, carry out the function of resolving social tension. Institutions like the ritual clowns, by giving expression to the antisocial tendencies, represent a safety valve which re-establishes equilibrium and health in the collective imaginary, which are jeopardized by the repressive aspects of society. The state of political satire in a given society reflects the tolerance or intolerance that characterizes it, and the state of civil liberties and human rights. Under totalitarian regimes any criticism of a political system, and especially satire, is suppressed. A typical example is the Soviet Union where the dissidents, such as Aleksandr Solzhenitsyn and Andrei Sakharov were under strong pressure from the government. While satire of
