What is a characteristic of a good scientific hypothesis?

A good scientific hypothesis is defined by its ability to be testable and falsifiable. This means that it can be subjected to experimentation and observation, allowing scientists to determine whether the hypothesis holds true or is proven false based on evidence. This characteristic is fundamental to the scientific method because it enables researchers to gather data and draw conclusions that either support or contradict the initial hypothesis. A hypothesis that cannot be tested or potentially disproven does not contribute to scientific knowledge, as it cannot be confirmed or refuted through empirical evidence.

Moreover, the requirement for a hypothesis to be testable and falsifiable ensures that scientific inquiry is grounded in observable phenomena. It promotes the advancement of knowledge by allowing for revisions and improvements in understanding as new data emerges.

In contrast, the other characteristics listed do not align with the principles of scientific inquiry. For instance, a hypothesis that is emotional or subjective lacks the objectivity necessary for scientific investigation. Similarly, while complexity can sometimes be necessary, it is not a requirement for a strong hypothesis; simplicity can often enhance clarity and focus. Lastly, a hypothesis does not need to be widely accepted; in fact, many groundbreaking scientific ideas initially face skepticism before gaining acceptance through rigorous testing and validation.
