Metrics: Reflections on the 2020s impact factors

As soon as the new impact factors (IF) are released, we start receiving dozens of emails from the journals celebrating the rise in their specific IF. However, this year's global rise in IF is particularly surprising. In the 2020 edition, the average IF of the journals in the Science Edition of...

However, this year's global rise in IF is particularly surprising. In the 2020 edition, the average IF of the journals in the Science Edition of JCR has increased 25.1% as compared to 2019 (Figure 1), representing more than four times the average increase in the three previous years (6.2%). Noteworthy, the IF of the 25 top journals in the list has risen 34%. Since the number of journals has only increased 1.3% (slightly lower than precedent years) and the number of citable items remains more or less constant, it might be speculated that this is due to an increase in citations (equating 25.7%, similar to the average increase in the IF).
