Why is it important to design and perform experiments even if they lead to rejecting a hypothesis?

Designing and performing experiments, even when they lead to rejecting a hypothesis, is crucial for advancing scientific knowledge. Such experiments help clarify the limits of current theories, identify new variables, and refine future research questions. Additionally, they contribute to the overall understanding of complex systems and can lead to unexpected discoveries. Ultimately, the process of testing hypotheses fosters critical thinking and innovation in science.
