Relations between science and publics are tricky affairs. While public participation in science is expanding, it regularly falls short of emancipatory hopes. Claudia Gbel analyzes these tensions as an important feature of contemporary society. She develops an extended model of inclusion in science by bringing science and technology studies, sociology of science and science communication studies into conversation. Popular science audiences and amateur researchers are conceptualized as integral to science, showing how these precarious roles complement professional scientists. The model offers a versatile framework for empirical research and new comparative perspectives on the multiple publics of science and their intricate relations.
