Metascience Is Not Enough – A Plea for Psychological Humanities in the Wake of the Replication Crisis

The replication crisis led to the rise of metascience as a possible solution. In this article, we examine central metascientific premises and argue that attempts to solve the replication crisis in psychology will benefit from a tighter integration of approaches from the psychological humanities. The first part of our article identifies central epistemic merits that metascientific endeavors can contribute to psychology. However, we argue secondly against the widespread claim that metascience is the only way to deal with the replication crisis in psychology and point to major epistemic problems: the one-sided notion of a singular scientific method, the homogenizing view of psychology, and the exclusion of practices of theorizing. As a possible compensation for such shortcomings, we introduce, third, the reflective and pluralistic approach of psychological humanities. In so doing, we show how psychological humanities can serve as an important complement to the objective of improving psychological research. Psychological humanities contribute to a more precise determination of validity, to ethical considerations, and a better understanding of psychology’s objects in regard to replication. Accordingly, we argue for the integration of psychological humanities into both metascience and psychology to provide a better basis for addressing epistemic and ethical questions.
