Résumé :

Twice in the history of psychology has there been a crisis of confidence. The first started in the 1960s and lasted until the end of the 1970s, and the second crisis dominated the 2010s. In both these crises researchers discussed fundamental concerns about the replicability of findings, the strength of theories in the field, the societal relevance of research, the generalizability of effects, and problematic methodological and statistical practices. On the basis of extensive quotes drawn from articles published during both crises, I explore the similarities and differences in these crises in psychology. I review changes in research practices that emerged in response to these concerns, as well as which concerns have not led to noticeable improvements, and will reflect on how we can prevent on what it would take to prevent a third crisis a few decades from now.
