Improving the Replicability of Psychological Science Through Pedagogy

Replications are important to science, but who will do them? One proposal is that students can conduct replications as part of their training. As a proof of concept for this idea, here we report a series of 11 preregistered replications of findings from the 2015 volume of Psychological Science, all conducted as part of a graduate-level course. As was expected given larger, more systematic prior efforts, the replications typically yielded effects that were smaller than the original ones: The modal outcome was partial support for the original claim. This work documents the challenges facing motivated students as they attempt to replicate previously published results on a first attempt. We describe the workflow and pedagogical methods that were used in the class and discuss implications both for the adoption of this pedagogical model and for replication research more broadly.
