The Post-Behavioural Approach in Political Science: Reconciling Empiricism and Normativity in the Study of Politics
Introduction
The evolution of political science as a discipline has been deeply shaped by methodological debates concerning the nature of political inquiry. One of the most significant developments in the 20th century was the rise of the behavioural revolution during the 1950s and 1960s, which sought to establish political science as a rigorous, value-neutral, and empirically grounded social science. However, by the late 1960s, criticisms of the behavioural approach’s perceived scientific positivism, detachment from pressing political issues, and neglect of normative questions gave rise to the post-behavioural movement. This new orientation, spearheaded by scholars such as David Easton, marked a critical departure from behaviouralism by reasserting the importance of ethical and normative dimensions in political inquiry while retaining the strengths of empirical methodology.
This essay explores the post-behavioural approach in political science as a theoretical and methodological response to the limitations of behaviouralism. It examines how post-behaviouralism seeks to reconcile the empirical rigor of behavioural science with the normative concerns of classical political philosophy, and how this synthesis has reshaped the epistemological foundations and practical relevance of the discipline.
The Behavioural Revolution: Context and Critique
To understand the post-behavioural turn, it is essential to situate it within the context of the behavioural revolution. Behaviouralism emerged as an effort to transform political science into a value-free, empirical discipline akin to the natural sciences. It emphasized the collection of quantifiable data, the testing of hypotheses, and the search for generalizations based on observable behaviour. Inspired by developments in psychology, sociology, and economics, behaviouralists such as Gabriel Almond, Robert Dahl, and David Truman focused on individual and group political behaviour rather than abstract institutions or normative ideals.
Despite its contributions to methodological sophistication, behaviouralism soon faced mounting criticism. Critics argued that the behavioural approach, in its pursuit of scientific objectivity, had become detached from the ethical and philosophical foundations of political inquiry. It privileged the “is” over the “ought,” marginalizing questions of justice, power, freedom, and the moral purpose of political life. Moreover, during the turbulent socio-political climate of the 1960s—marked by civil rights struggles, anti-war movements, and global decolonization—behaviouralism’s perceived indifference to real-world political injustices was increasingly viewed as a form of intellectual escapism.
The Emergence of the Post-Behavioural Approach
In response to these criticisms, the post-behavioural approach emerged as a corrective paradigm. It was formally articulated by David Easton, who had been a central figure in the behavioural revolution but later became one of its leading critics. In his influential 1969 presidential address to the American Political Science Association (APSA), Easton declared that political science must become “relevant” to the urgent political problems of the time and move beyond sterile empiricism.
Post-behaviouralism did not reject the empirical and scientific aspirations of behaviouralism entirely. Instead, it sought to synthesize empiricism with normative analysis. It emphasized that political science must be both analytical and purposive, attending to how things are while also engaging with how they ought to be. This shift did not entail a return to purely philosophical speculation but called for a reintegration of normative inquiry within empirically grounded research.
Core Tenets of the Post-Behavioural Approach
Several key features characterize the post-behavioural approach:
- Relevance over Methodological Purism: Post-behaviouralism insists that political science must address real-world problems—poverty, war, inequality, oppression—rather than pursue methodological refinement for its own sake. It prioritizes substantive relevance over methodological exclusivism.
- Value Commitment and Normative Engagement: Unlike the behaviouralists who emphasized value-neutrality, post-behavioural scholars accept that political inquiry is inherently value-laden. The goal is not to eliminate values but to make them explicit, examine them critically, and integrate them with empirical analysis.
- Action-Oriented Research: Post-behaviouralism encourages political scientists to be not merely observers of political phenomena but agents of change. Research should inform and contribute to the improvement of political institutions and democratic life.
- Eclectic Methodology: Post-behaviouralism embraces methodological pluralism. It does not privilege quantitative methods over qualitative ones but encourages the use of diverse approaches—historical, interpretive, ethnographic—provided they are intellectually rigorous and substantively meaningful.
- Bridging the Gap Between Theory and Practice: Post-behaviouralism aspires to connect academic research with policymaking, public discourse, and social activism. It recognizes that political theory must have practical implications for governance, citizenship, and justice.
Reconciling Empirical Analysis with Normative Concerns
The defining feature of post-behaviouralism is its insistence on the interdependence of facts and values in political inquiry. While behaviouralists sought to emulate the natural sciences by isolating variables and establishing causal relationships, post-behaviouralists argue that political science cannot be divorced from moral judgment. Political phenomena—unlike chemical reactions or biological processes—are shaped by human intentions, ethical dilemmas, and contestable interpretations.
By integrating normative concerns with empirical analysis, post-behaviouralism revives classical questions about the good life, justice, liberty, and power while grounding them in the realities of contemporary political systems. For example, rather than merely analyzing voting patterns or institutional behaviour, a post-behavioural study might also ask whether electoral systems promote democratic participation or reinforce structural inequalities.
This normative turn reorients political science toward a critical rather than merely descriptive role. It encourages scholars to examine not only how institutions function but whether they are just, equitable, and responsive to human needs. In doing so, post-behaviouralism revives the ethical vocation of political science without abandoning empirical rigor.
Impact on the Discipline and Contemporary Relevance
The post-behavioural approach has had a profound and enduring influence on the development of political science. It paved the way for the emergence of critical theory, feminist political thought, post-colonial theory, and constructivist approaches, all of which reject value-neutrality and emphasize the normative dimensions of power, identity, and discourse.
Moreover, contemporary global challenges—climate change, authoritarian resurgence, democratic backsliding, and social injustice—underscore the continued relevance of post-behavioural principles. Political science cannot afford to remain methodologically sophisticated but substantively indifferent. In an era marked by epistemic crises and normative uncertainty, post-behaviouralism’s call for engaged scholarship serves as both a methodological guide and an ethical imperative.
Conclusion
The post-behavioural approach in political science represents a critical reconciliation between empirical analysis and normative concern. It emerged out of dissatisfaction with the behavioural revolution’s technocratic detachment and offered a vision of political inquiry that is both scientifically credible and morally engaged. By insisting on the relevance, responsibility, and ethical commitment of political science, post-behaviouralism restored the discipline’s connection to the broader humanistic questions that animate political life.
In this sense, post-behaviouralism is not merely a methodological stance but a philosophical orientation—one that affirms the dual responsibilities of the political scientist as both analyst and citizen. It revitalizes political science by making it not only a tool for understanding power but also a force for realizing justice.
