A recent study addresses the problem of sensationalism in the communication of science news, an issue we deal with on a regular basis. The study was titled “The association between exaggeration in health related science news and academic press releases: retrospective observational study“. The results show two interesting things – that university press releases frequently overhype the results of studies, and that this has a dramatic effect on overall reporting about the research.
The authors reviewed “Press releases (n=462) on biomedical and health related science issued by 20 leading UK universities in 2011, alongside their associated peer reviewed research papers and news stories (n=668).” They found that 40% of the press releases contained exaggerated health advice, 33% overemphasized the causal connection, and 36% exaggerated the ability to extrapolate animal and cell data to humans.”
When press releases contained such exaggeration, 58%, 81%, and 86% of news stories, respectively, contained similar exaggeration, compared with exaggeration rates of 17%, 18%, and 10% in news when the press releases were not exaggerated.
This study points a finger directly at academic press offices as a significant source of bad science news reporting. This does not let other links in the news chain off the hook, however. (more…)
