Why must a hypothesis be testable in scientific inquiry?

• A. It is always true and requires no data.
• B. It guarantees success if tested.
• C. It requires no evidence.
• D. It can be tested and potentially supported or refuted by data.

Answer: (D)

In science, a hypothesis must be testable so it can be evaluated against reality. A testable hypothesis makes a concrete prediction that can be measured or observed, and data gathered from experiments or observations can either support or refute it. When the results align with the prediction, the hypothesis gains support; when they don’t, it’s challenged and revised. Without testability, there’s no way to use evidence to distinguish good explanations from bad ones, and scientific knowledge wouldn’t progress. The idea that a hypothesis can be tested and potentially supported or refuted by data is the principle that keeps inquiry empirical and objective.
