Sets, Net Effects, Causal Mechanisms, Subpopulations, and Understanding: A Comment on Mahoney

This comment discusses the suggestions made in Mahoney’s “Constructivist Set-Theoretic Analysis: An Alternative to Essentialist Social Science” (2023). Mahoney presents an approach to cases of intersectionality or confounding which produce causal results unlike those that result from traditional net effects causal modeling. He presents it as an alternative to “essentialism,” which he describes as a cognitive error. These alternatives have the same problems as those he attributes to net effects analysis, with one exception: the method does allow for the identification of subpopulations with different causal mechanisms producing different outcomes for this subpopulation.
