Using Preprint Sources in Science News: Do Transparent Disclosures Enhance Credibility?

This study tested whether the transparent use of preprint sources affects the perceived credibility of science news and scientists. In an experiment, U.S. adults read a news report describing COVID-19 research as a “preprint” (with varying levels of detail) or as simply a “study.” There were no main effects of disclosing preprint status, but indirect effects emerged. For those who noticed the disclosure, both brief and fuller depictions of a study’s preprint status enhanced the credibility of the reporting and the scientists behind the research. However, perceiving the science to be uncertain negatively mediated the effects of preprint disclosure on credibility appraisals among Republicans.
