Prolific non-research authors in high impact scientific journals: meta-research study

Journalistic papers published in high impact scientific journals can be very influential, especially in hot fields. This meta-research analysis aimed to evaluate the publication profiles, impact, and disclosures of conflicts of interest of non-research authors who had published > 200 Scopus-indexed papers in Nature, Science, PNAS, Cell, BMJ, Lancet, JAMA or New England Journal of Medicine. 154 prolific authors were identified, 148 of whom had published 67,825 papers in their main affiliated journal in a non-researcher capacity. Nature, Science, and BMJ have the lion's share of such authors. Scopus characterized 35% of the journalistic publications as full articles and another 11% as short surveys. 264 papers had received more than 100 citations. 40/41 most-cited papers in 2020-2022 were on hot COVID-19 topics. Of 25 massively prolific authors with > 700 publications in one of these journals, many were highly-cited (median citations 2273), almost all had published little or nothing in the Scopus-indexed literature other than in their main affiliated journal, and their influential writing covered diverse hot topics over the years. Of the 25, only 3 had a PhD degree in any subject matter, and 7 had a Master's degree in journalism. Only the BMJ offered conflicts of interest disclosures for prolific science writers in its website, but even then only 2 of the 25 massively prolific authors disclosed potential conflicts with some specificity. The practice of assigning so much power to non-researchers in shaping scientific discourse should be further debated and disclosures of potential conflicts of interest should be emphasized.
