The __replication crisis__ (or __replicability crisis__ or __reproducibility crisis__) is an ongoing (2018) methodological crisis primarily affecting the social sciences in which scholars have found that the results of many scientific studies are difficult or impossible to reproducibility on subsequent investigation, either by independent researchers or by the original researchers themselves. The crisis has long-standing roots; the phrase was coined in the early 2010s as part of a growing awareness of the problem - wikipedia
Because the reproducibility of experiments is an essential part of the scientific method, the inability to replicate the studies of others has potentially grave consequences for many fields of science in which significant theories are grounded on unreproducible experimental work.
The replication crisis has been particularly widely discussed in the field of psychology (and in particular, social psychology) and in medicine, where a number of efforts have been made to re-investigate classic results, and to attempt to determine both the reliability of the results, and, if found to be unreliable, the reasons for the failure of replication.
# Scope of the crisis
According to a 2016 poll of 1,500 scientists reported in the journal ''Nature (journal)'', 70% of them had failed to reproduce at least one other scientist's experiment (50% had failed to reproduce one of their own experiments) - wikipedia
In 2009, 2% of scientists admitted to falsifying studies at least once and 14% admitted to personally knowing someone who did. Misconducts were reported more frequently by medical researchers than others.
# Causes of the crisis
- Generation of new data/publications at an unprecedented rate. - Compelling evidence that the majority of these discoveries will not stand the test of time. - Causes: failure to adhere to good scientific practice & the desperation to publish or perish. - This is a multifaceted, multistakeholder problem. - No single party is solely responsible, and no single solution will suffice.
See Causes of the crisis for a more complete exploration of this issue.
# Addressing the replication crisis
Reproducibility has been referred to as "the cornerstone of science". Replication studies attempt to evaluate whether published results reflect true findings or false positives. The integrity of scientific findings and reproducibility of research are important as they form the knowledge foundation on which future studies are built - wikipedia
