What most accurately describes the "reproducibility crisis"?

The term "reproducibility crisis" refers to the growing recognition that many scientific studies, across various research fields, cannot be reliably reproduced or replicated. This issue is not confined to one specific area, such as experimental psychology; rather, it spans multiple disciplines, including medicine, biology, social sciences, and more. The crisis highlights the importance of rigorous methodologies, transparency in research practices, and the need for validation in scientific work to ensure that findings are not only valid in a single study but can be confirmed in subsequent experiments or analyses. As such, the correct description of the reproducibility crisis acknowledges its broad impact across all research fields, rather than limiting it to a single discipline or suggesting it is merely a secondary concern related to certain aspects of research methodologies.
