|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/Poundstone: most are generalizations - Nicods criterion (Raven paradox): Relevance - black and non-black non-ravens are irrelevant.
I 60 Poundstone: even observing black ravens is virtually irrelevant - I 88 poor hypoth. spoil good supporting evidence.
Auxiliary hypotheses/Coherence theory/Poundstone: additional hypotheses usually areassumptions about the functioning of the instruments - problem: often the applicability of the modus tollens is not guaranteed - E.g. Uranus was correctly predicted due to perturbations, Neptune wrongly predicted based on the same assumptions and methods.
