Inductive reasoning is making conclusions based on patterns you observe.The conclusion you reach is called a conjecture. In logic there’s a close relationship between deductive and valid arguments, and there’s a similar relationship between inductive and strong arguments. For this reason, we need a different term for evaluating inductive arguments. All Rights Reserved. There’s no absolute cut-off between strength and weakness, but some arguments will be very strong and others very weak, so the distinction is still useful even if it is not precise.

Here we’re supposed to infer that, simply because Julie has dark hair, she’s probably Chinese. You’re acknowledging that the conclusion doesn’t follow with certainty from the premises, but you think the inference is strong, that the conclusion is very likely true, given the premises.

Joe's shirt today is blue. It is one of the two types of reasoning; deductive reasoning … (9:41), Quiz: Inductive Arguments and Scientific Reasoning. Since the premises of an inductive argument do not necessitate the truth of its conclusion, inductive arguments cannot be valid. After careful observation we have not seen any hummingbirds all day in this forest. To find out if an inductive argument is strong or not, we run … Categorizing inductive arguments as strong v weak is similar to categorizing arguments as valid or invalid for deductive arguments. For instance, we noted one inductive possibility (probability only) for the first man (x): If only three hats are used (one on x, one on y, and one on z), then we know x has a higher probability of having on a red hat IF he sees two white hats, one on y and one on z. The sun is out, the temperature is cool, there is no rain in the forecast, the flowers are in bloom, and the birds are singing.
