Growing knowledge impact of gene-editing technology on public acceptance: a longitudinal analysis in Japan

Genome editing (GE) technology holds significant promise for advancements in crop development and medical applications. However, public acceptance of GE in Japan remains uncertain. This study aimed to examine how knowledge impacts public acceptance of GE technology, focusing on differences across diffusion stages and application purposes. Using ordinary least squares regression on repeated survey data collected from 2018 to 2023 in Japan (n = 6,234), we investigated the influence of knowledge on support for GE in consumer benefits, producer benefits, and medical technology. Our findings revealed that the effect of knowledge on technology acceptance has strengthened over time. Consumers with greater knowledge of GE are increasingly supportive of its advancement, emphasizing the growing importance of information as the technology becomes more widespread. This research highlights the role of transparent policy discussions in fostering public trust and support, thereby promoting the successful integration of new technologies into society.
