David Crotty writes: “The value of open science (increased transparency, open data, open access to research results) has become increasingly obvious during the current global health crisis. Both the positives (rapid reporting and sharing of information) and the negatives (the glut of bad science being issued as preprints and promoted via mainstream media without proper curation) are now evident, with the good generally outweighing the bad. Despite the daily evidence of the importance of shifting to an open science environment for research, the economic fallout from the pandemic is going to make necessary progress difficult and slow.”
