What challenges, if any, lie ahead for the field?
The Open Science movement is a positive development for psychology and other disciplines. Yet, some scholars distrust all work on a subject that appeared before pre-study registrations existed. Scholars ought to examine all of the evidence and then see how registered and unregistered results compare.
Psychology has experienced replication crises in the past and grown from them. For example, in the late 1960s and 1970s, attitudes and personality traits were thought to be failures in predicting behavior; by the 1980s, scholars had improved their methods and were robustly predicting behaviors using both attitudes and traits.
Unfortunately, scholars with no training in systematic reviews still try to conduct them; then, they learn from the expert feedback they receive from peer reviewers. In such cases, more extensive revisions are necessary in order to become published, which strains reviewers.
Finally, psychologists train to be psychologists, but why not put science first and learn about a phenomenon from any discipline that studies it? Many other scientists use the same methods as psychologists and study the same or similar phenomena. We talk about areas of science being “silos,” but silos have been disappearing from farms for decades! Borrowing a perspective from, for example, sociology or social epidemiology to inform a systematic review focused on mental health interventions could well lead to advances for both psychology and outside fields.
