Do Registered Reports Make Scientific Findings More Believable to the Public?

Registered reports are an important initiative to improve the methodological rigor and transparency of scientific studies. One possible benefit of registered reports is that they may increase public acceptance of controversial research findings. We test this question by providing participants in a large US-based sample (n = 1,500) with descriptions of the key features of registered reports and the standard peer-review process, and then eliciting credibility judgments for various scientific results. We do not find evidence that participants view findings from registered reports as more credible than findings conducted under a standard (non-registered) report. This was true for both plausible and implausible study findings. Our results help clarify public attitudes and beliefs about scientific findings in light of recent methodological developments.
