No blog ContraFactos & Argumentos encontrei um artigo bem recente e que me parece interessante ler: Online News Credibility: An Examination of the Perceptions of Newspaper Journalists. Como o título sugere, o texto analisa a credibilidade das notícias online na perspectiva dos jornalistas que trabalham em jornais impressos. O paper mostra que o jornal impresso tem mais credibilidade que o online, por muito motivos. Como exemplo, ele cita que o impresso tem regras mais profissionais e mais notabilidade, sendo mais moderado que o da internet. O resumo não me deixou muito empolgado, mas preciso ler antes de comentar. Olhei também a bibliografia, que está um pouco defasada, mas que compensa conferir. Existem alguns textos que podem servir de referência para futuras pesquisas.
Abstract: This study examines print and online daily newspaper journalists’ perceptions of the credibility of Internet news information, as well as the influence of several factors—most notably, professional role conceptions—on those perceptions. Credibility was measured as a multidimensional construct. The results of a survey of U.S. journalists (N=655) show that Internet news information was viewed as moderately credible overall and that online newspaper journalists rated Internet news information as significantly more credible than did print newspaper journalists. Hierarchical regression analyses reveal that Internet reliance was a strong positive predictor of credibility. Two professional role conceptions also emerged as significant predictors. The populist mobilizer role conception was a significant positive predictor of online news credibility, while the adversarial role conception was a significant negative predictor. Demographic characteristics of print and online daily newspaper journalists did not influence their perceptions of online news credibility.
