An h-index of 4 for a “top” researcher is neither automatically embarrassing nor automatically acceptable. It is a starting point for investigation. If the researcher is a mathematician or a humanist, it may be entirely appropriate. If they are a biomedical principal investigator with two decades of funding, it is a serious red flag demanding explanation. The wise evaluator will abandon the lazy reflex of praising high h-indices and condemning low ones. Instead, they will use the h-index as a blunt instrument—one that, at very low values like 4, merely signals: Look closer. The truth is in the details.
An means a researcher has published at least four papers that have each been cited at least four times. This metric is widely used to balance a scholar's productivity (number of papers) with their impact (number of citations). Significance and Context hindex of 4 top

Here is an example of what a researcher's profile looks like with an h-index of 4, followed by a fictional example paper that would contribute to such a score.
