Abstract

Generally, public opinion is measured via polls or survey instruments, with a majority of responses in a particular direction taken to indicate the presence of a given ‘public opinion’. However, discursive psychological and related scholarship has shown that the ontological status of both individual opinion and public opinion is highly suspect. In the first part of this article I draw on this body of work to demonstrate that there is currently no meaningful theoretical foundation for the construct of public opinion as it is typically measured in surveys, polls, or focus groups. I then argue that there is a particular sense in which the construct of public opinion does make sense. In deliberative democratic forums participants engage in dialogue with the aim of coming to collective positions on particular issues. Here I draw on examples of deliberative democratic forums conducted on the social and ethical implications of science and technology. Conversation between participants in deliberative democratic forums is ideally characterized by individuals becoming informed about the issues being discussed, respectful interactions between participants, individuals being open to changing their positions, and a convergence towards collective positions in the interest of formulating civic solutions. The end-product of deliberation on a given issue might thus be termed a deliberative public opinion. ‘Deliberative public opinion’ is neither a cognitive nor an aggregate construct, but rather a socio-historical product. Criteria for its legitimacy rely on the inclusiveness of diversity of perspectives and the degree to which collective positions are defensible to a larger society.
