Inductive Reasoning. Induction is a major kind of reasoning process in which a conclusion is drawn from particular cases. It is usually contrasted with deduction, the reasoning process in which the conclusion logically follows from the premises, and in which the conclusion has to be true if the premises are true. In inductive reasoning, on the contrary, there is no logical movement from premises to conclusion. The premises constitute good reasons for accepting the conclusion. The premises in inductive reasoning are usually based on facts or observations.
