Public knowledge, public trust: Understanding the 'knowledge deficit'

This article examines the 'knowledge deficit' model, which still persists in liberal, technological societies. It is based upon the assumption that expert forms of knowledge, both in the sciences and the humanities, provide a sufficient basis for deciding the most important public policy questions. In this view, public perceptions and beliefs that run counter to this expert knowledge provide unacceptable justifications for public policies. Instead, support of expert knowledge needs to be 'built' through education and public relations strategies. This view is challenged on the basis of basic democratic theory, using the debate about genetically modified maize in Mexico as an example. 'Knowledge deficits' also exist on the side of experts.
