A Review of Rozeboom’s Ideas with an Analysis of Issues in Null Hypothesis Significance Testing

Abstract

Reexamining William Rozeboom’s recommendations for the future direction of disciplines such as psychology and philosophy is imminent due to the pressing issues in null hypothesis significance testing (NHST). An overreliance on NHST forms the basis of the replication crisis in psychology. Likewise, the discipline’s stringent guidelines on significance levels convey a pressure to publish, which is also significantly contributing to the replication crisis. As researchers’ careers are staked on the extent to which they publish, reassessing the fundamental issues with NHST within the context of Rozeboom’s ideas is paramount. In this brief review, I focus specifically on Rozeboom’s critiques of NHST and on a proposed alternative for evaluating the depth of findings within the framework of theoretical psychology. Thereafter, I compare his foreboding concerns with modern issues facing the validity of psychology and posit Rozeboom prophesized the failings of the discipline years ahead of his time.
