Which is NOT a characteristic of a good hypothesis?

Question

BlackTom AI · Accepted Answer

A robust scientific hypothesis must be testable and falsifiable: it should make clear, observable predictions that can be supported or refuted by evidence.

1) Relevant knowledge points and concepts
- Falsifiability: A hypothesis must be able to be proven wrong by an observation or experiment (Karl Popper).
- Testability/Observability: Empirical methods must be able to assess the claims.
- Predictive power: A good hypothesis predicts specific outcomes that follow logically from it.
- Tentativeness: Scientific hypotheses are provisional; evidence can support but not absolutely “guarantee” truth.

2) Step-by-step reasoning
- Examine each option against the criteria above.
- If an option meets falsifiability, testability, predictiveness, and logical basis, it is characteristic of a good hypothesis.
- If an option claims certainty that contradicts tentativeness and falsifiability, it fails.

3) Calculations or intermediate steps
- No numerical calculations are needed. The logical evaluation proceeds by matching each option to the criteria.

4) Why the correct answer is correct
- "It's guaranteed to be proven correct" contradicts the provisional nature of science. A hypothesis cannot be guaranteed true before or even after some supporting evidence, because future observations may falsify it. Good hypotheses are open to refutation; guarantee of correctness removes falsifiability and thus is not a scientific characteristic.

5) Why other options are incorrect (briefly)
- "It's testable through observation or experimentation": Correct characteristic — allows empirical assessment.
- "It predicts a specific outcome": Correct — provides clear expectations that can be checked.
- "It's based on logical reasoning": Correct — hypotheses should be grounded in prior knowledge and logic.

6) Conclusion
Because a good hypothesis must be testable, predictive, logical, and falsifiable—not guaranteed true—the option "It's guaranteed to be proven correct" is NOT a characteristic of a good hypothesis. This matches the provided correct answer.
