An inductive argument supports a conclusion without making it logically certain. Its strength depends on the quality, relevance and coverage of the evidence. Observing several examples may help, but examples drawn from one narrow setting can support only a narrow conclusion.
New evidence can weaken a previously reasonable inference. That makes the wording of a conclusion important: “this often happens under these conditions” may fit the evidence better than “this always happens.” The confidence should match what the observations can actually support.
