“Post-truth”, a social trend that has emerged since the beginning of the 21st century, is against scientific evidence-based policy-making. Scientific literacy is a way of thinking that puts emphasis on not only the understanding of science and technology but also the capacity to utilize science and technology. It should be acquired by the general public to take the outcome of science and technology into our society properly. At the same time, it is an extremely important concept to deal with post-truth. The objective of this research is to clarify the roles of relevant stakeholders in order to promote scientific evidence-based policy-making. In this regard, the role of parliamentary technology assessment institutions and academia is focused to reveal the point concerning the policy decision and scientific literacy in Japan.
