Why We Need Knowledge-based Journalism in Politicized Science Debates

Largely overlooked by researchers studying the science of science communication are the specific journalistic practices and media structures that might enable more constructive public debate in politicized science controversies. In this commentary, we discuss the role that journalists can play as influential knowledge professionals, drawing on insights from the studies in this section of the special issue. In doing so, we outline three complementary approaches to what Thomas Patterson calls ?knowledge-based journalism.? By way of these approaches, journalists and their news organizations can contextualize and critically evaluate expert knowledge; facilitate discussion that bridges entrenched ideological divisions; and promote consideration of a broader menu of policy options and technologies. We conclude by discussing the implications for journalism education.
