Reproducibility Project

The Reproducibility Project: Psychology was a collaboration completed by 270 contributing authors to repeat 100 published experimental and correlational psychological studies to see if they could get the same results a second time.[1] The project was set up in 2011 by Brian Nosek and his collaborators.[2] It showed that only 39 percent of replications obtained statistically significant results.[3][4] While the authors emphasize that the findings reflect the reality of doing science and there is room to improve reproducibility in psychology, they have been interpreted as part of a growing problem of "failed" reproducibility in science.[5][6][7] There was no evidence of fraud and no evidence that any original study was definitely false. The conclusion of the collaboration was that evidence for frequently published findings in psychological science was not as strong as originally claimed. This may be a result of pressure to publish and a hypercompetitive culture across the sciences that favor novel findings and provide little incentive for replicating findings.[8]

One earlier study found that around $28 billion worth of research per year in medical fields is non-reproducible.[9]
