Who engages whom?—Deficit communication in participatory science governance as democratic deficit

Abstract This article builds on the evolving relationship between science and society, focusing on the increasing emphasis on public participation in science decision-making processes. Public participation in science is often regarded as an embodiment of democratic principles that grant citizens the opportunity to engage with and influence scientific and technological developments. However, deficit models of science communication in participatory governance may be turning into democratic deficits. This article critically examines the deficit model of science communication, highlighting its potential democratic deficit. Drawing on empirical evidence from two case studies in a rural, socio-economically underdeveloped region in Portugal, the authors analyse the dynamics between agency and structure in hierarchical decision-making structures and power relations. We recommend policy implications to enhance the democratic quality of participatory science governance processes, based on convergence of initiatives, transparency, and new prospects for science communication.
