- A deduction is “an argument incorporating the claim that it is impossible for the conclusion to be false given the premises are true” (Hurley 33). Basically, a deduction, or deductive argument, is one where the premises are true and the conclusion is also true. There is no doubt or error in the conclusion; it must be true. An example of a deduction is “The meerkat is a member of the mongoose family. All members of the mongoose family are carnivores. Therefore, it necessarily follows that the meerkat is a carnivore” (Hurley 33). This is a deduction because the premises are both true, therefore the conclusion is also true, since the premises support the conclusion. An induction, or inductive argument, is one where the claims are improbably true if the premises are true. With inductions, there is a chance that the premises may be true but the conclusion is false. Inductive arguments will sometimes use generalizations or guesses based off the premises rather than an actual fact. So, the difference between inductive and deductive is that deductive arguments have true premises and a true conclusion, whereas inductive arguments have true premises but may or may not have a true conclusion. Generally speaking, deduction uses more descriptive or factual valid reasoning, whereas inductive arguments make generalizations or guesses that create conclusions which may not be true (even the premises are).
