|Hypotheses: Hypotheses are assumptions made before performing experiments to compare the results of these experiments with them. Hypotheses must be fed by a given theory that is at least rudimentary, which determines what belongs to the domain of the objects involved, the concepts used and the possible consequences, and what cannot belong to it. In the course of the theory formation there is a mutual correction of assumptions and test results and the set of concepts and sentences of the theory. See also theories, methods, verification.|

Hypotheses/Feyerabend: Hypotheses can be used that contradict well-confirmed theories and/or experimental results. The sciences can be promoted by proceeding contrainductively.
Ad-Hoc Hypotheses/Feyerabend: initial difficulties caused by the change are mitigated by ad-hoc hypotheses, which therefore sometimes have a positive function. They give new theories a break, and they indicate the direction of future research.
