In 2015, a collaboration of 270 scientists published the results of a large attempt to investigate systematically to what extent earlier findings in psychology can be replicated. They selected 100 studies of three important scientific journals and conducted close replications. About one-third to one-half of the findings in the replications matched the results of the original studies. Reference: Open Science Collaboration. (2015).
