What is the difference between inductive and deductive reasoning?
Inductive reasoning and deductive reasoning are the two most prominent approaches to critical thinking and argumentation. Each plays a crucial role in reasoning and argumentation, but they serve different functions:
- Inductive reasoning relies on specific observations to form general conclusions. Example: “The sun has risen every day of my life; therefore, the sun will always rise every day.”
- Cannot prove a conclusion with absolute certainty
- Can result in informal logical fallacies (i.e., errors of content)
- Deductive reasoning (or formal reasoning) relies on general principles to form specific conclusions. Example: “All humans are mortal. Socrates was human. Therefore, Socrates was mortal.
- Can prove a conclusion with absolute certainty if the premises are true and the argument has a valid form
- Can result in formal logical fallacies (i.e., errors of form)

Inductive reasoning moves from specific observations to broad generalizations while deductive reasoning starts with a general premise and applies it to reach a conclusion. If the premises are true, conclusions in deductive reasoning are certain. In inductive reasoning, any conclusions remain probabilistic (i.e., uncertain). You can use either approach in different research designs, but it’s […]
