Old and new direction in psychological science

Abstract

In this commentary paper, I discuss the significance of building an evidence evaluation system to evaluate the strength of evidence and the consistency between phenomena and theories in psychological science. I also discuss the usefulness of introducing the concept of “evidence level,” which is popular in evidence-based medicine. We should review the evidence-level further by referring to various external factors involving the theoretical predictability. In addition, transparency in the review process and sharing the evaluation criteria would be important.
