Fostering Transparency and Reproducibility in Psychological Science

Psychological science is hard. This short paper focuses on two issues. One has to do with the importance of understanding statistical power and how post-hoc data explorations and selective reporting can lead to exaggerated estimates of effect size (which in turn contribute to replication failures). The other topic is tools research psychologists can use to improve the reproducibility of their procedures and analyses. The paper closes with a comment on the deeper challenge of improving the usefulness and testability of theories in psychology.
