Final answer:
The concept of changing criteria emphasizes the significance of a hypothesis or theory's adaptability to rigorous and evolving standards of proof. In scientific inquiry, extraordinary claims necessitate extraordinary evidence, highlighting the importance of criterion changes. Grading systems also reflect criterion changes through shifts in academic assessment over time.
Step-by-step explanation:
The question addresses the concept that the more the criterion changes, the better proof of the adaptability and robustness of a hypothesis or theory. In the context of scientific inquiry, when criterion changes occur, such as escalating standards for evidence or shifting baseline assessments, it provides a clearer indication that a theory is reliable or requires amendment. For instance, as empirical data accumulates and the criteria for validation intensify, a hypothesis must repeatedly meet the more stringent benchmarks to be accepted as true.
Moreover, when considering claims against established beliefs, the principle that extraordinary claims require extraordinary evidence emphasizes that significant criterion changes demand a proportional increase in the quality and quantity of supporting evidence. Traditional views may thus be challenged by novel hypotheses that can consistently withstand evolving and rigorous evaluative standards.
In the context of grading systems, the observation that letter grades no longer correspond to historical representations of academic achievement illustrates criterion changes over time. This shift can be seen as either grade inflation or a recalibration of standards, and understanding how these metrics evolve is essential for equitably assessing student performance.
