Tyranny of the majority

Tyranny of the majority refers to a situation in majority rule where the preferences and interests of the majority dominate the political landscape, potentially sidelining or repressing minority groups and using majority rule to take non-democratic actions. This idea has been discussed by various thinkers, including John Stuart Mill in On Liberty and Alexis de Tocqueville in Democracy in America.

To reduce the risk of majority tyranny, modern democracies frequently have countermajoritarian institutions that restrict the ability of majorities to repress minorities and stymie political competition. In the context of a nation, constitutional limits on the powers of a legislative body such as a bill of rights or supermajority clause have been used. Separation of powers or judicial independence may also be implemented.

In social choice, a tyranny-of-the-majority scenario can be formally defined as a situation where the candidate or decision preferred by a majority is greatly inferior (hence "tyranny") to the socially optimal candidate or decision according to some measure of excellence such as total utilitarianism or the egalitarian rule.
