Social participation in Anvisa's regulations: hybrid, colloquial, and scientific evidence for democratic decision-making.

Anvisa's public consultation (PC) is the most widely used social participation mechanism in current health regulations, which was based on antagonistic movements: the democratization of decision-making and State counter-reformation. Starting from the concept of social participation, defined as various actions from society related to public decision-making, which values diversity and the exercise of citizenship, the present article discusses the possibility of PCs configuring a democratic regulation process by considering popular beliefs and colloquial evidence, and promoting the creation of hybrid evidence in an evidence-moderated model. Despite the different interests, the PCs open the door to opportunities for democratic deliberation by society in the search of understanding, where it is expected that the State will make the best decision and justify it. In this sense, the role of evidence in clarifying complex issues is defined as a space where dissent, believed to democratize society, is important in revealing the limits of scientific evidence in an environment of information asymmetry. Finally, this article aims to refute technocracy as an instrument of power in health regulations, thereby achieving the greatest democratic potential of Anvisa's regulations.
