Framing science - The stem cell controversy in an age of press/politics

Applying the theories of agenda building and frame building and previous work related to the shared negotiations between sources and journalists in constructing news dramas, this article examines the role of the mass media in the evolution of the stem cell controversy. How does a scientific issue gain, maintain, or lose political and media attention? What forces combine to emphasize certain dimensions of an issue over others? Using data from a content analysis of stem cell-related articles appearing between 1975 and 2001 in the New York Times and the Washington Post, the authors analyze patterns of media attention, media framing, and media sourcing across stages of scientific, political, and policy development.
