Difference between Induction and Deduction

Posted on In

Induction Reasoning

Induction reasoning aims at developing a theory. It moves from specific observations to general conclusions. The quality of the conclusions obtained via induction depends on the quality of observations and analysis.

eg.

Observations:

Howard is a men. Howard is mortal.

Conclusion:

All men are mortal.

Note

Mathematical Induction should not be confused with induction reasoning used in philosophy. This mathematical methods examines infinitely many cases to prove a general statement by a finite chain of deductive reasoning.

Deduction Reasoning

Deduction reasoning aims at testing an existing theory. It formulate hypothesis and accept/reject it with data and facts. Deduction is idea-first followed by observations to draw a conclusion. Deduction's conclusions are solid.

eg.

Theory: All men are mortal.

Observation: Howard is a men.

Conclusion: Howard is mortal.
