Embracing variability and complexity and the explanatory reductionism of scientific realism

Abstract

We agree with Arocha’s criticism of psychological science’s reliance on statistical procedures that factor out intraindividual variability and the complex dynamics inherent to behavior, as well as with his call for the adoption of a metatheoretical framework that embraces such variability. However, we disagree that scientific realism provides such a framework, given its reductive privileging of certain forms of explanation over others. We advocate, instead, a process-relational paradigm and the explanatory pluralism that it supports, allowing psychological science to more dynamically, and realistically, model individual human behavior.
