Credibility of Preprints: An interdisciplinary Survey of Researchers

Preprints increase accessibility and can speed scholarly communication if researchers view them as credible enough to read and use. Preprint services, though, do not provide the heuristic cues of a journal’s reputation, selection, and peer review processes that are often used as a guide for deciding what to read. We conducted a survey of 3,759 researchers across a wide range of disciplines to determine the importance of different cues for assessing the credibility of individual preprints and preprint services. We found that cues related to information about open science content and independent verification of author claims were rated as highly important for judging preprint credibility. As of early 2020, very few preprint services display any of these cues. By adding such cues, services may be able to help researchers better assess the credibility of preprints, enabling scholars to more confidently use preprints, thereby accelerating scientific communication and discovery.
