The Open Science Framework announces the opening of a prediction market (PM) to accompany a new replication project.  Over the period September 2016 to September 2017, 21 experimental studies that were published from 2010-2014 in the journals Science and Nature  will be replicated.  For each study, PM participants will be able to bet on the following proposition: “The effect in the replication is in the same direction as in the original study, and is statistically significant with a p-value smaller than 0.05.”  

There will be two chances to replicate each study.  The first study will select a sample size corresponding to 90% power to detect 75% of the effect size reported in the original study.  If the first replication attempt is unsuccessful, a second study will be conducted with a sample size corresponding to 90% power to detect 50% of the effect size reported in the original study.
