A study explored the question of whether there is an adversary press, by examining the recent trends in adversarial attitudes among newspaper journalists in the United States. Using a differentiation model for delineating the nature and boundaries of American adversarial journalism, the study re-analyzed the data from two national surveys. The first (by Weaver and Wilhoit) involved telephone interviews of 1,001 print and broad-cast journalists. The other (by Stinnett et al.) involved questionnaires mailed to 1,211 journalists at U.S. daily newspapers. Results of the re-analysis revealed: (1) that while young and old journalists take a moderate position on the usefulness of an adversary press, the middle-aged cohort has increased adversarial sentiment over the last 5 years; and (2) that these intra-cohort trends may be explained by three factors: age, cohort, and period. (Five figures, nine tables of data, and 20 notes are included.) (SR)
