The Politics of Expertise in Congress and the News Media

Objective. Experts are increasingly active in U.S. policymaking, but what accounts for their varied visibility is unclear. The agenda‐setting and media studies literature suggest that experts are generally neutral, distant actors in policymaking whose products are made visible by Congress and the news media when helpful. This study examines how and when the intentional efforts of experts can also affect their relative visibility and whether a proliferation of expert organizations, as has occurred in American policymaking in recent decades, is correctly viewed as creating conditions for more rational, thoughtful decisionmaking, as some existing scholarship might suggest. Methods. I consider the conveyance of expertise among a sample of 66 public policy think tanks in congressional testimony and three national newspapers between 1991 and 1995. In a multivariate analysis, I evaluate what accounts for the quantity of congressional and media visibility. I then use a content analysis to examine differences in the nature of visibility received by think tanks. Results. Washington‐based think tanks and think tanks of no identifiable ideology have some advantage in gaining congressional and media visibility overall. Think tanks deemed credible receive more, and more substantive, visibility than those that are ideological and marketing‐oriented. Conclusions. Cumulatively, my findings suggest that more credible, staid, not identifiably ideological expert organizations are slightly favored by congressional staff members and journalists to provide guidance on issues and news stories. More ideological and marketing‐oriented sources of expertise, by contrast, are more relied upon to build support for ideas, either in staged congressional hearings or on the editorial pages of newspapers. Expert organizations can affect their relative visibility; the evidence is mixed on whether their proliferation makes policymaking and decisionmaking better informed or more rational or thoughtful.
