According to Spellman, these factors, coupled with increasingly limited resources and misaligned incentives for doing scientific work, led to a crisis in psychology and other fields. [50] According to Andrew Gelman, [57] the works of Paul Meehl, Jacob Cohen, and Tversky and Kahneman in the 1960s-70s were early warnings of replication crisis.
The authors emphasized that the findings reflect a problem that affects all of science and not just psychology, and that there is room to improve reproducibility in psychology. In 2021, the project showed that of 193 experiments from 53 top papers about cancer published between 2010 and 2012, only 50 experiments from 23 papers could be replicated.
It finds that the majority of the replication concern the medical and social sciences (especially, psychology and behavioral economics) and that there is for now no standardized evaluation criteria: "methods of assessing replicability are inconsistent and the replicability percentages depend strongly on the methods used."
The replication crisis (or credibility crisis) is a methodological crisis in science that researchers began to acknowledge around the 2010s. The controversy revolves around the lack of reproducibility of many scientific findings, including those in psychology (e.g., among 100 studies, less than 50% of the findings were replicated). [5] [6]
The growth of metascience and the recognition of a scientific replication crisis have bolstered the paper's credibility, and led to calls for methodological reforms in scientific research. [8] [9] In commentaries and technical responses, statisticians Goodman and Greenland identified several weaknesses in Ioannidis' model.

The article currently states that the "replication crisis most severely affects the social sciences and medicine.". To make this claim, it is not sufficient to show that replicability is low in the mentioned fields. Instead, a source would have to state that this problem is more prevalent in social sciences and medicine than in others. While ...
