Verification and balance in science news: How the New Zealand mass media report scientific claims

摘要

Accuracy and balance are fundamental principles of journalism worldwide. The main way that journalists ensure accuracy is by verifying the information in their stories against an independent account. Most journalists who report science must rely on scientific experts to verify the validity of claims they report. However, previous studies have found that science stories commonly contain only one source. Journalists typically maintain balance by fairly presenting opposing views. Previousstudies show that when journalists present conflicting claims, they tend to balance thedifferent opinions equally, regardless of the empirical evidence on which those claimsare based.This thesis investigated verification and balance in New Zealand mass media sciencenews, using a national survey and in-depth interviews with New Zealand journalists,and a content analysis of newspaper, radio and television coverage. The content analysisshowed that verification was uncommon in New Zealand science news, and only 32%of science claim stories cited more than one source. Furthermore, 23% of stories werefive sentences or shorter, and the majority of stories (65%) were drawn from overseasnews organisations and wire services. When opposing views were presented, journaliststended to use a balancing strategy without any interpretation of which view wassupported by the weight of evidence.The interviews indicated that these practices are partly influenced by time constraints.New Zealand almost completely lacks specialised science reporters, and only five of thesurveyed journalists had a dedicated science round. Most surveyed journalists spent lessthan 20 hours per month reporting science, and few had formal training in science.However, journalists also said that the normative dimensions of being a journalist wereimportant. In particular, journalists tended to value balance and fairness over ensuringthe validity of claims they report. Exploratory focus groups suggested that audiencesmay also strongly value a balanced and unbiased approach to science reporting.
