Do normative scientific practices and incentive structures produce a biased body of research evidence?

The Reproducibility Project: Psychology was a crowdsourced empirical effort to estimate the reproducibility of a sample of studies from scientific literature. 270 authors from around the world completed 100 replications.

The investigation sampled from the 2008 issues of three prominent psychology journals—Journal of Personality and Social Psychology, Psychological Science, and Journal of Experimental Psychology: Learning, Memory, and Cognition. Individuals or teams of scientists follow a structured protocol for designing and conducting a close, high-powered replication of a key effect from the selected articles.

During the data collection phase, researchers followed a protocol to guide them through the replication process. In April 2015 all data collection was completed.

All RP:P replication reports can be accessed from the RP:P overview page.

A record of the researcher guide can be found here.
