This is a list of conspiracy theories that are notable. Many conspiracy theories exist with varying degrees of popularity, frequently related to clandestine government plans and elaborate murder plots. Conspiracy theories usually deny consensus or cannot be proven using the historical or scientific method and are not to be confused with research concerning verified conspiracies such as Germany's pretense for invading Poland in World War II. In principle, conspiracy theories are not false by default and their validity depends on evidence just as in any theory; although they are often discredited a priori due to the cumbersome and improbable nature of many of them.
