RT Journal Article SR Electronic T1 The readability of scientific texts is decreasing over time JF bioRxiv FD Cold Spring Harbor Laboratory SP 119370 DO 10.1101/119370 A1 Pontus Plavén-Sigray A1 Granville James Matheson A1 Björn Christian Schiffler A1 William Hedley Thompson YR 2017 UL http://biorxiv.org/content/early/2017/03/28/119370.abstract AB Clarity and accuracy of reporting are fundamental to the scientific process. The understandability of written language can be estimated using readability formulae. Here, in a corpus consisting of 707 452 scientific abstracts published between 1881 and 2015 from 122 influential biomedical journals, we show that the readability of science is steadily decreasing. Further, we demonstrate that this trend is indicative of a growing usage of general scientific jargon. These results are concerning for scientists and for the wider public, as they impact both the reproducibility and accessibility of research findings.
