In this interview, Ruth Groff discusses how she came to be a realist, her role as a community organizer, her relationship to critical realism, and various issues arising from her published work over the years. Discussion ranges across the nature of positivism and its legacy, the concept of falsehood, realism about causal powers, mind-independent reality, the history of philosophy, and the underlying interest in ideology-critique that runs through her thinking.

Lack of clarity about underlying philosophical commitments leads to lack of clarity at other levels of analysis. Here I show that the literature on so-called “causal mechanisms” is rife with conceptual problems, stemming from insufficient rigor with respect to the metaphysics of causation.

Is evidential pluralism possible when we move to the social sciences, and if so, to what degree? What are the analytical benefits? The answer put forward in this article is that there is a tradeoff between how serious social science methodologies take the study of mechanisms and the analytical benefits that flow from evidential pluralism. In the social sciences, there are a range of different approaches to studying mechanisms, differentiated by the degree to which the ‘process’ is unpacked theoretically, and (...) whether the approach takes seriously the particular nature of social phenomena and the epistemological consequences that flow from this, as in realist approaches to the study of mechanisms, or whether more neopositivist-based foundational assumptions are adopted. Depending on which approach to study mechanisms is used, evidential pluralism is either: easy but superficial, very productive but challenging, or almost impossible because of the fundamental differences between the types of claims being made and the forms of evidence used.
