What is a fool-proof way to remember the difference between deductive and inductive reasoning?
gpt
In deductive reasoning, the truth of the conclusion is *necessitated* given the truth of the premises  - you cannot mantain that the premises are true and the conclusion is false without contradicting yourself. In inductive reasoning, the premises provide *support* for the conclusion, but not to the degree of logical necessity. Even in the most convincing inductive argument, you can imagine a case, however unlikely and contrived, where the premises are true but the conclusion turns out false.
