I'm interested in how I could assess prominence of specific scholars outside the STEM (science, tech, engineering, math) fields. As a scholar in the humanities or social sciences, how do you gauge the prominence of another scholar you previously never heard of?
Note: This question is a genuine curiosity of mine, and comes with no intention of denouncing or belittling another research field.
In math, engineering, computer science and physics (I'm an applied math PhD student), a lot of papers are are available for free (as a preprint) on Arxiv and a lot of researchers are thoroughly catalogued on Google Scholar. So if I encounter a new academic "Ms. A", I can look up her work on Google Scholar to quickly skim her h-index, total citations, and read her most popular research works. This gives me some (but not all!) understanding of how reputed she is in her field. Skimming her works on Arxiv allows me to understand some subtleties of her work that aren't normally articulated on the news media. I was surprised to find out when a fellow PhD student in the humanities told me that she doesn't know[Edit: I initially wrote here that apparently Google Scholar isn't extensively used in non-STEM fields. But I did some searches and it seems to be popular there as well.] I'm curious of what an analogous digital catalogue to quickly skim the works of other scholars"usual" process would be in non-STEM fields.
My motivation to find out about this comes from the self-proclaimed experts appearing on media. Reputed public intellectuals aren't necessarily great academics, so I'm interested in finding out how I would go about and assess prominence of scholars in a non-STEM field.
Update: After some search, I found out that recent scholars in the humanities and social science seem to be using Google Scholar quite extensively too. However, I'm still curious of how other people would approach the original question.
