Seven key insights from critical realism and their implications for ecological thinking and action in community psychology.

This article explores some of the possible links between community psychology and critical realism, a relatively new approach to the philosophy of science that has received little attention from community psychologists. Critical realism is presented in relation to seven key insights that can be linked to fundamental tenets of the ecological approach in community psychology. These insights are: (1) A complex reality exists independently of our ideas about it, and this reality is knowable, although imperfectly. (2) Reality is composed of a complex and stratified hierarchy of open systems. (3) Causality is best understood in terms of causal processes that may or may not be directly observable or generalizable; these processes involve complex interactions among generative mechanisms and contextual conditions. (4) Theory and theorizing about causal processes are central to both scientific explanation and practical action. (5) Theory exists at multiple levels of abstraction, ranging from models to metatheory. (6) A diversity of methods can provide evidence in the search for causal processes operating in context. (7) As social scientists, we have an obligation to use social science knowledge to promote human flourishing. Although these insights may be familiar to many community psychologists who adopt an ecological approach to their work, we suggest that clearly articulating these principles can provide more solid foundations for inquiry in the field. We conclude the article by highlighting how critical realism may help to bridge the research-practice gap in community psychology and similar social sciences.
