The idea that when selecting between two different theories with equal explanatory value, one should select the most simple and concise theory is known as Options: (a) Criterion of falsifiability (b) Critical theory (c) Guide of simplicity (d) Rule of parsimony ✅ Correct Option: (d) Rule of parsimony Explanation: The Rule of Parsimony, also known as Occam’s Razor, states that among competing explanations, the simplest one should be preferred. It avoids unnecessary complexity and assumptions. In research and theory building, parsimony ensures clarity, efficiency, and testability. It does not mean oversimplification but favors economy of explanation. Hence, the principle guiding selection of simpler theories is the rule of parsimony. 10 PPSC-Oriented Facts: 1. Parsimony favors simplicity. 2. Known as Occam’s Razor. 3. Used in scientific theory selection. 4. Avoids unnecessary assumptions. 5. Enhances clarity. 6. Improves testability. 7. Supports logical reasoning. 8. Complexity reduces usefulness. 9. Scientific explanations seek economy. 10. Philosophy influences research methods.
