Could someone please explain the difference between inductive and deductive reasoning as argument techniques.
Thanks in advance!
Deductive reasoning: Premise 1: I like red cars.
Premise 2: My car is red.
Conclusion: I like my car.
Inductive reasoning:Premise 1: Cars can be red.
Premise 2: All the cars I've ever seen are red.
Conclusion: All cars are red.
Basically, deductive reasoning involves taking general statements and drawing specific, unequivocal conclusions from them (i.e. there's no way I couldn't like my car in that first scenario because of the logical parametres we set up.) But inductive reasoning involves making general statements based on specific and potentially limited information (i.e. it's possible that our conclusion could be untrue in the second scenario if I, by chance, had never seen a blue/white/yellow car in my life.)
That's not to say deductive reasoning is inherently better than inductive reasoning; a lot of the conclusions we make about the world are based on inductive reasoning (eg. 'All known humans need oxygen to breathe, the guy sitting over there looks like a human, therefore, if I choke him to deprive him of oxygen, he will die.' <-- most people would agree that's a sound argument, but it's possible for the conclusion to be untrue for a number of reasons - e.g. he's an android, he has some circulatory abnormality that lets him breathe through his ears, he's actually a projected hologram, etc.)
In L.A. argument terms, an author might use inductive logic to try and imply something (e.g. Our last Prime Minister was a corrupt, garbage human being. Our current Prime Minister is a corrupt, garbage human being. Hence, all Prime Ministers past and future are corrupt, garbage human beings) or deductive logic, which'd be less common but still analyse-able.
Just be careful not to
evaluate the author's argument by picking apart any logical inconsistencies. You can call something 'inductive reasoning,' but don't then explain how the author's rationalisation is flawed, or that their conclusions are unfounded. Assume things are persuasive, and just discuss how & why
