A reproducibility effort has put high-profile journals under the spotlight by trying to replicate a slew of social-science results. In the work, published on 27 August in Nature Human Behaviour1, researchers attempted to reproduce 21 social-science results reported in Science and Nature between 2010 and 2015 and were able to reproduce 62% of the findings. That’s about twice the rate achieved by an earlier effort2 that examined the psychology literature more generally, but the latest result still raises questions about two out of every five papers studied.
