Abstract

Recent criticisms on the way psychologists analyze their data, as well as cases of scientific fraud, have led both researchers and the general public to question the reliability of psychological
research. At the same time, researchers have an excellent tool at their disposal to guarantee the robustness of scientific findings: replication studies. Why do researchers rarely perform replication studies? We explain why p-values for single studies fail to provide
any indication of whether observed effects are real or not. Only
cumulative science, where important effects are demonstrated
repeatedly, is able to address the challenge to guarantee the
reliability of psychological findings. We highlight some novel
initiatives, such as the Open Science Framework, that aim to
underline the importance of replication studies.
