This presentation introduces research projects involving ELSI and RRI in the fields of cellular agriculture technology and viral infections research, which have recently attracted attention. New knowledge and technologies often cause controversy due to their unfamiliar nature in existing social systems. Because psychology employs empirical analysis, it has great potential to strike a balance between being close to the development of technology and reflecting and reconsidering its ideal way. The author has led an interdisciplinary research to examine the social impact of cell agriculture technology in collaboration with experts in political science, anthropology, and biology in RInCA. Cellular agriculture technology, represented by 'cultivated meat,' is expected to lead to a new food production system that does not involve the death of animals. We first identified the factors behind the public acceptance of cultivated meat in the Japanese context, including the relational view on nature and concerns about the food crisis. Second, we proposed the whole-part framework for meat from considerations of various social spheres. We investigate the meaning of meat in cultural constructions, wherein the relationship between the whole body and meat as a part of it is important. This insight can speculatively update some of the ELSI of cell agriculture. The project critically reviews the excessive market view of 'cultivated meat' as a mere commodity and calls attention to the broader problems that our society faces. The author is currently involved in a project examining the case of institutionalization of viral infections research, where public distrust of science can cause serious social confusion. Psychology is expected to shed light on communication gaps regarding viral infection research and provide clues for dialogue among stakeholders. Psychology can contribute to balancing the sensitive ELSI/RRI practices, but should be careful not to endorse the idea of merely enlightening the public.
