Inductive and Deductive Reasoning

Inductive reasoning is when the writer takes specific facts and details and uses them to draw conclusions. This kind of reasoning can be probable, but not always true. For example, a child may grow up with 3 brown dogs and assume that all dogs are brown. This child is using inductive reasoning; however, it is not true that all dogs are brown, just all the dogs the child has known. That is an example of an improbable inductive reasoning. A probable inductive reasoning would be saying that football linemen are big. Ted is a lineman; therefore, Ted is big. While this is most likely true, it may not be. Ted may be small, but very strong and can perform well as a lineman. Deductive Reasoning is when the writer starts with a conclusion and then presents facts, details, and examples. For example, all trouts are fish. All fish have gills; therefore, all trouts have gills. Because the premises are true the conclusion is also true. If the premises are not all true then the conclusion is usually not true either.
