Strong scientific theorizing is needed to improve replicability in psychological science

  • Timothy Carsel (a1), Alexander P. Demos (a1) and Matt Motyl (a1)


The target article makes the important case for making replicability mainstream. Yet, their proposal targets a symptom, rather than the underlying cause of low replication rates. We argue that psychological scientists need to devise stronger theories that are more clearly falsifiable. Without strong, falsifiable theories in the original research, attempts to replicate the original research are nigh uninterpretable.
