Out of the laboratory: scientists' discursive practices in their encounters with activists

This article analyses the discursive practices of scientists engaged in controversial science in their narrated accounts of encounters with activists. It explores what happens when scientific credibility and authority are challenged in a public debate on the benefits and risks of such science. The aim is to understand how scientists discursively negotiate and make sense of their encounters with activists, the range of subject positions they claim, and how power is implicated in identification with the public. The article shows how scientists counter emotional appeals, utilizing both scientific and public identities respectively to legitimate the epistemic and moral authority of science and to marginalize opposing activists. It is argued that a unitary view of scientific identity is inadequate. Rather, in times of public challenge and controversy, scientists may utilize a multiplicity of subject positions to achieve identification with public interests. The discursive construct, public interest, is interpreted as a contested discursive space and a discursive resource for influencing public opinion.
