Abstract
Hypothesis testing is often used for inference in the social sciences. In particular, null hypothesis significance testing (NHST) and its p value have been ubiquitous in published research for decades. Much more recently, null hypothesis Bayesian testing (NHBT) and its Bayes factor have also started to become more commonplace in applied research. Following preliminary work by Wong and colleagues, we investigated how, and to what extent, researchers misapply the Bayes factor in applied psychological research by means of a literature study. Based on a final sample of 167 articles, our results indicate that, not unlike NHST and the p value, the use of NHBT and the Bayes factor also shows signs of misconceptions. We consider the root causes of the identified problems and provide suggestions to improve the current state of affairs. This article is aimed to assist researchers in drawing the best inferences possible while using NHBT and the Bayes factor in applied research.
