It is important to judge the relevance of facts prior to performing scientific experiments because this helps to ensure that the experiments are well-designed and focused on answering specific research questions. By considering the relevance of the facts, researchers can identify the most important variables to measure and control in the experiment. This helps to reduce the risk of collecting unnecessary or irrelevant data, which can waste time and resources.
Additionally, judging the relevance of facts can help researchers to identify any potential biases or limitations in their experiments. This can help them to design experiments that are more objective and accurate, and to interpret their results more carefully.
Overall, judging the relevance of facts is an important part of the scientific process because it helps researchers to focus their efforts on answering important research questions and to design and conduct experiments that are more likely to produce meaningful and reliable results.
