Preregister an experiment

Commit to the design before you see the data.

Preregistration is what separates evidence from after-the-fact rationalization. Tell us the hypothesis, the design, and the analysis plan now, and we'll publish a public preregistration page within a week of review. The registry will publish your results whatever they are — positive, null, or negative.

Already filing on AEA RCT Registry, OSF, or AsPredicted? Add the URL below — we'll defer to that record for the canonical protocol and link to it from your public preregistration page.
