Poor correlation of the Journal Impact Factor with scientific impact: Michael's Domain

Kirstine's bookmarks 2019-04-26


The Impact factor is misused. It was developed to evaluate journals (for librarians to decide whether to subscribe to a journal or not) and has then subsequently been used to evaluate individual articles and even individual researchers. The correlation between the Impact Factor and the actual scientific impact (e.g. measured in terms of citations) has been steadily declining over the last decades (see e.g. this research: https://arxiv.org/abs/1205.4328). From my personal experience, I can confirm that this is true as the correlation between the JIF and the actual number of citation among my own publications is around 0.32. This is pretty bad if your goal is to use the JIF as a proxy to predict scientific impact in terms of future citations.
