Open science is an academic movement to transform scientific research into a more open endeavor. For the purposes of this paper, we define open science as the infrastructure of a “statistical revolution,” which indicates the transformation of fundamental ideas in psychometrics. The four basic components of open science are: (1) open access, (2) open data, (3) data-centric science, and (4) civil science. With regard to open data and open access, we surveyed the present situation of psychological research and considered how it is associated with the statistical revolution internationally and domestically in Japan. To date, the introduction of open science to academic psychology circles has arrived relatively late in Japan. The future prospects of psychology in open science are discussed, especially with regard to what to do and how to do open science as a researcher.
