From my academic experience of research design in a clinical study conducted in the interdisciplinary area of health psychology, social psychology and clinical medicine, I discuss the reproducibility and the “ideals” of research design in Japanese psychology research. To realize the “ideals” of research design in psychological research to reveal the universal nature of psychological phenomenon as complex and probable, it will be necessary to establish a robust theory through considerable theoretical studies, critical discussions, and experiments and surveys based on small hypotheses, and to conduct an empirical study using experimental design after registration in a psychological research registry, in which researchers should disclose their research design including estimated effect-size and calculated sample-size in advance.
