Replication studies determine both the validity of scientific conclusions and provide insights into the type of methods and reporting that are necessary for robust results.
Social Sciences Replication Project
This collection features the results of the Social Sciences Replication Project, which carried out direct replications of 21 experimental studies in the social sciences that were published in Science and Nature between 2010 and 2015. Replicating previously published studies is necessary not only in order to determine which results are robust and can be used as foundations for future research but also to inform future research designs and questions. Here we highlight these different opportunities afforded by replication studies by presenting the Social Sciences Replication Project’s work alongside commentaries by eight of the authors whose work failed to replicate (according to the criteria established by the replicating authors) and a News and Views that places the work in a broader perspective.
Evaluating the replicability of social science experiments in Nature and Science between 2010 and 2015
Camerer et al. carried out replications of 21 Science and Nature social science experiments, successfully replicating 13 out of 21 (62%). Effect sizes of replications were about half of the size of the originals.
News & Views
It is important for research users to know how likely it is that reported research findings are true. The Social Science Replication Project finds that, in highly powered experiments, only 13 of 21 high-profile reports could be replicated. Investigating the factors that contribute to reliable results offers new opportunities for the social sciences.
