In addressing the discrepancy of scientists’attitudes and behaviors regarding their participation in science popularization，existing studies have explored the social dimension that influences scientists’intentions. However，they have inadequately addressed the epistemic dimension. This paper focuses on three types of practices：AI + science games developed by scientists，“AI + science”summer lab，and the integration of scientific instrumentation and data for science popularization. These examples illustrate scientists’participation in the age of AI for science. These new patterns of science popularization enable the public to engage directly in scientific epistemic practices. Consequently，scientists actively address the diverse epistemic demands of the public. Such interactions benefit scientific research，collaborative engagement of scientists and the public in scientific practice，and provide opportunities for collaboration among scientists from different fields in science popularization. Furthermore，these practices facilitate the transfer of skills and enhance the public’s understanding of the complexities of science. Ultimately，these initiatives yield mutual epistemic and social benefits for both scientists and the public. This paper proposes it as an effective strategy for integrating epistemic and social approaches to enhance scientists’motivation to participate in science popularization，thereby fostering synergy between science popularization and technological innovation.
