"\n This class comprises the action of making categorical hypotheses based on inference rules and theories; By categorical hypotheses we mean assumptions about the kinds of interactions and related kinds of structures of a domain that have the character of \u201Claws\u201D of nature or human behavior, be it necessary or probabilistic. Categorical hypotheses are developed by \u201Cinduction\u201D from finite numbers of observation and the absence of observations of particular kinds. As such, categorical hypotheses are always subject to falsification by new evidence. Instances of S8 Categorical Hypothesis Building include making and questioning categorical hypotheses.\n "@en . .
