Psychology Literature Mostly Unreliable

Lee Jussim argues that if a claim appears only as a peer‑reviewed paper, chapter, or conference presentation in psychology, you should provisionally disbelieve it until independent replications accumulate. He assembles an equation that adds unreplicable findings (~50% by his account) plus overclaiming, citation of bad work, censorship and fabrication to justify an approximate 75% false‑claim rate. — If true, the claim forces media, policymakers, clinicians, and funders to change how they treat single psychology studies — privileging replication, preregistration, and evidence‑synthesis before action.
