Lancet‘s impact factor increased from 79.3 in last year’s report to 202.7. NEJM’s impact factor nearly doubled as well, from 91.2 to 176.1. Five other journals also had impact factors greater than 100 for the first time, and also published a lot of COVID-19 research: the Journal of the American Medical Association, Lancet Respiratory Medicine, Nature Reviews Drug Discovery, Nature Reviews Immunology, and Nature Reviews Molecular Cell Biology.
Irrelevant numbers at all – even when used with 3 decimal points precision as in an email that I received this week
COVID-19 has clearly shown the craziness of our scientific rating system.
