Knowledge democracy is an emerging concept that addresses the relationships between knowledge production and dissemination, as well as the functions of the media and democratic institutions. Although democracy has been the most successful concept of governance for societies for the last two centuries, representative democracy, which became the hallmark of advanced nation-states, seems to be in decline. Media politics is an important factor in the downfall of the original meaning of representation, yet more direct forms of democracy have not yet found an institutional embedding. Further, the Internet has also drastically changed the rules of the game, and a better educated public has broad access to information, selects for itself which types to examine, and ignores media filters. Some citizens have even become 'media' themselves. In a time where the political agendas are filled with combatting so-called evils, new designs for the relationships between science, politics and media are needed. This book outlines the challenges entailed in pursuing a vital knowledge democracy.
