Questioning Psychology's Findings: A Real Crisis

The replicability crisis in psychology refers to the fact that many psychological findings, especially those from experimental studies, cannot be reliably reproduced. Replicability and reproducibility are cornerstones of the scientific method and are necessary for establishing the validity and robustness of a finding. In this video, I review how the replicability crisis started and then worsened as researchers adopted questionable research practices (QPRs), including the use of small sample sizes, selective reporting of data, and the manipulation of outliers.
