Inference to the best explanation (abduction) is a reasoning method used in philosophy of science and everyday judgment to select among competing hypotheses. Given a set of observations, the method identifies the hypothesis that would, if true, best explain the evidence. It operates under constraints of explanatory power, simplicity, consistency with known facts, and fruitfulness. Unlike deduction (which guarantees conclusions) or induction (which generalizes from instances), abduction generates explanatory hypotheses for later testing.
