What is a strength of using the scientific method in psychology?

• A. Self-correcting knowledge
• B. Eliminates all errors
• C. Guarantees universal laws
• D. Focus only on animals

Answer: (A)

Using the scientific method in psychology is strongest because it builds self-correcting knowledge. The ideas we test with observable data, and findings are checked through replication and peer scrutiny. When new evidence appears, theories are revised or replaced, so incorrect or limited explanations can be overturned and better ones developed. This ongoing process makes psychological knowledge more reliable over time. The method also uses objective measures and standardized procedures to reduce bias and random error, though it can’t eliminate all mistakes. It doesn’t promise universal laws, since human behavior varies with context, and while animal research is useful, psychology isn’t about focusing only on animals.
