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

• A. It eliminates error
• B. It allows flexibility when results are inconsistent
• C. It cannot be applied to humans
• D. It demands large samples

Answer: (B)

A strength of using the scientific method in psychology is its iterative, self‑correcting nature, which lets researchers adapt when findings don’t fit predictions. Instead of sticking to one idea, scientists test hypotheses, collect data, and refine theories based on results. When results are inconsistent, they can change how variables are defined or measured, use different research designs, add better controls, or compare competing explanations to see which best fits the evidence. This flexibility helps produce more reliable knowledge because conclusions are revised in light of new data rather than being treated as final after a single study. Remember, the method doesn’t eliminate error or require always large samples, and it can be applied to humans, though ethical considerations guide how studies are conducted.
