Petrovich provides an insightful study on analytic philosophy (AP) with the intention of determining whether this sub-field of philosophy has been operating within what Kuhn calls a normal science framework. Through a citation analysis, Petrovich concludes that AP does not exhibit the sort of pattern that we would expect of a field operating in a normal science phase. I take issue with Petrovich’s way of measuring normal science. I provide some insight into how we might better measure normal science in future studies.
