In Scientific American, Louise Lief discusses the problem of rising public distrust of science:
We live in a moment when preventable infectious diseases like measles are spreading because parents distrust vaccines, and scientists at government agencies are being told not to use terms like “evidence-based.” The president dismisses the findings of a National Climate Assessment by more than 300 scientists and 13 federal agencies that warns of massive economic and environmental damage totaling hundreds of billions of dollars, crop failures, disrupted supply chains and multiple threats to human health, saying, “I don’t believe it.”
But when I argued in favor of the proposition (Resolved: “Science writers are responsible for building public trust in science”) during a debate at the National Association of Science Writers’ 2018 annual conference last fall, the majority of science writers and science journalists present voted that building public trust in science was not the responsibility of science writers.

Kathleen Hall Jamieson, director of the Annenberg Public Policy Center at the University of Pennsylvania’s Annenberg School for Communication also tackled the science trust question at the NASW conference, and researchers at Cardiff University have traced credibility and accuracy problems to press releases from scientists’ own academic institutions.
If a problem is discovered or a study is retracted, said Jamieson, the scientist or scientific journal needs to explain to journalists and the public how the error was discovered, what the problem is, and what steps are being taken to ensure it doesn’t happen again.
Scientists often make it hard for journalists to cover these three interrelated issues, she says. Scholarly journal publication protocols may cause scientists to write one article on the problem they’re investigating, and a second or third article on processes and solutions, resulting in coverage that emphasizes problems and shortchanges corrective action.
For their part, researchers at Cardiff University found that press releases from scientists’ own academic institutions about their work were a significant source of exaggerated claims and spin, even though most scientists can approve their wording.
Their study of press releases from 20 leading British universities on health-related science news found that when the press releases exaggerated, it was likely the news stories would too.
An analysis of 41 news articles on randomized controlled trials based on 70 press releases showed only four articles that contained exaggerated claims not included in the press release or journal abstract. Interestingly, they also found the hype and spin intended to tempt the media did not result in more news coverage.
