Conventional Twist

Als Conventional Twist (conventional stratagem) wird nach dem Philosophen Karl Popper die nachträgliche Veränderung einer Hypothese durch zusätzliche ad-hoc-Annahmen bezeichnet, die sich in der Vergangenheit als falsch herausgestellt haben ^[1]. Diese zusätzlichen Annahmen waren nicht Bestandteil der ursprünglichen Hypothese.

Der Conventional Twist ist ein typisches Merkmal der Umwandlung von Theorien in unwissenschaftliche Theorien.

↑ "Some genuinely testable theories, when found to be false, are still upheld by their admirers – for example by introducing ad hoc auxiliary assumptions or by interpreting the theory ad hoc in such a way that it escapes refutation. Such a procedure is always possible, but it rescues the theory from refutation only at the price of destroying, or at least lowering, its scientific status. (I later describe such a rescuing operation as a ‘conventional twist’ or ‘conventional stratagem’.)." in: Popper K, Vermutungen und Widerlegungen, 1963. ISBN 3-16-147311-61963
