Open, but to what end? Early disclosure and public dissemination of scientific preprints

Preprints allow researchers to disclose completed manuscripts before journal-organised peer review has been completed. Their benefits include rapid communication, accessibility, a dated record of disclosure, and independence from editorial decisions about publication. A separate feature of contemporary preprinting receives less attention: the same manuscripts generally become available through the same public information channels to specialists and non-specialists alike. This essay asks whether the benefits of early scholarly disclosure necessarily require such frictionless public dissemination. A recent palaeontological preprint proposing a keratinised perioral structure in Camarasaurus provides the starting point for this discussion. The anatomical inference remains open to further testing, whereas its visually persuasive reconstruction can circulate more readily than the qualifications underlying it. Research on public understanding of preprints shows that manuscript status is not always understood, although explanatory interventions can help under some conditions. Rather than arguing against preprints or for restricting them to professional researchers, I suggest that early disclosure and wider public dissemination should be treated as analytically separable functions. Preprint systems should more systematically test ways of keeping review status visible as manuscripts and their component parts move through the wider information environment.
