Replication Crisis

The replication crisis, also known as the reproducibility or replicability crisis, refers to widespread failures to reproduce published scientific results. Because the reproducibility of empirical results is the cornerstone of the scientific method,[2] such failures undermine the credibility of theories and challenge substantial parts of scientific knowledge. https://en.wikipedia.org/wiki/Replication_crisis

• Psychology and medicine have been focal points for replication efforts, with researchers systematically reexamining classic studies to verify their reliability and, when failures emerge, to identify the underlying causes.[3][4] Data strongly indicate that other natural and social sciences are also affected.[5]
• The phrase "replication crisis" was coined in the early 2010s as part of a growing awareness of the problem.[6] Considerations of causes and remedies have given rise to a new scientific discipline known as metascience,[7] which uses methods of empirical research to examine empirical research practice.
