Behaviouralism is an approach in political science that emerged primarily in the United States during the 1940s and 1950s. It represents a significant shift in the methodology of studying politics, moving away from traditional, normative, and philosophical approaches towards a more empirical, quantitative, and scientific study of observable political behavior. Traditional political science had largely concentrated on constitutions, legal institutions, political philosophy, historical development, and formal structures of government. Behaviouralists argued that studying these formal structures alone could not adequately explain how politics actually operated in society.Behaviouralism therefore placed the actual behaviour of political actors at the centre of political inquiry. It examined how citizens voted, why individuals participated or remained politically inactive, how political attitudes were formed, how pressure groups influenced governments, and how political leaders made decisions. In this way, behaviouralism broadened the subject matter of political science from formal institutions to the human beings who operated within political systems. The approach also attempted to establish political science as a more systematic and scientifically oriented social science.
At its core, behaviouralism defines political science as the study of observable human behavior in political contexts. It aims to develop generalizations, theories, and potentially predictions about political phenomena by rigorously applying scientific methods, statistical analysis, and empirical verification.
The behavioural approach was therefore concerned not merely with describing political events but with explaining the causes and consequences of political behaviour. It sought relationships between variables and attempted to discover recurring patterns in political life. For example, rather than simply recording election results, a behaviouralist would investigate the social, economic, psychological, and demographic factors that influenced voting behaviour.
Behaviouralism also encouraged political scientists to employ methods such as surveys, interviews, sampling, statistical analysis, content analysis, comparative research, and other techniques borrowed from sociology and psychology. The objective was to make political conclusions more testable, systematic, and replicable.
Instead of studying institutions, laws, or philosophical ideals in isolation, it examines how individuals and groups actually act in political situations (e.g., voting patterns, political participation, decision-making processes of leaders). This shift meant that formal political institutions were studied in relation to the people who operated within them. Behaviouralists were interested in political attitudes, public opinion, political socialization, group behaviour, leadership behaviour, and patterns of participation.
It advocates for the use of systematic research procedures, data collection, measurement, and statistical analysis to uncover regularities and patterns. The political scientist was expected to formulate a research problem, develop hypotheses, collect relevant evidence, analyze the evidence systematically, and draw conclusions on the basis of observable data.
Behaviouralists aimed to separate facts from values, believing that political science should strive for objectivity and avoid making normative judgments about what should be (values) in favor of understanding what is (facts). This principle reflected the behaviouralists' attempt to distinguish empirical political inquiry from moral or philosophical arguments concerning the ideal political order.
All theoretical propositions and generalizations must be testable and verifiable through observable evidence. A political argument could not simply be accepted because it appeared logically persuasive; it needed to be supported or challenged through evidence obtained from political reality.
Behaviouralism arose as a reaction against the perceived shortcomings of traditional political science, which was often seen as overly descriptive, historical, philosophical, or legalistic, lacking empirical rigor and explanatory power. Traditional approaches frequently concentrated on formal constitutions, governmental structures, legal rules, and political thought. Behaviouralists believed that political science should move beyond the study of formal institutions and examine the actual processes through which political behaviour occurred.The emergence of behaviouralism was also associated with broader intellectual developments in the social sciences. Psychology and sociology increasingly relied on empirical research, surveys, statistical methods, and systematic observation. Political scientists consequently began adopting similar methods to investigate political attitudes and behaviour.
The roots can be traced to early 20th-century American political scientists like Charles Merriam and the "Chicago School," who advocated for a more scientific study of politics. Merriam argued for greater attention to empirical investigation and encouraged political scientists to make use of developments in psychology, sociology, and other social sciences. His work provided an important intellectual foundation for the later behavioural movement.
The post-war era saw a boom in scientific methodologies across various social sciences (sociology, psychology, economics). Funding for scientific research increased, and there was a desire to make political science a more "cumulative science" capable of generating testable theories and reliable knowledge. The rapid development of survey research, statistical techniques, computers, and quantitative methods further strengthened the behavioural approach.
Prominent figures associated with the rise of behaviouralism include David Easton, Robert Dahl, Gabriel Almond, and Seymour Martin Lipset. They pushed for the adoption of research methods from psychology and sociology, such as survey research, statistical analysis, and experimental design. Their work helped establish political behaviour, political culture, political participation, public opinion, and comparative political analysis as important areas of political science.
David Easton, a leading behaviouralist, famously outlined the "intellectual foundation stones" of behaviouralism, which serve as its defining characteristics. These characteristics represented an attempt to establish a systematic methodology for studying politics. Together, they emphasized that political science should be empirical, theory-oriented, methodologically rigorous, interdisciplinary, and capable of producing testable knowledge.
The belief that there are discoverable uniformities in political behavior that can be expressed as generalizations or theories with explanatory and predictive power. Behaviouralists rejected the idea that every political event was completely unique and argued that recurring patterns could be identified through systematic research. For instance, similar social and economic conditions might produce similar patterns of political participation in different settings.
All knowledge claims must be testable through observable empirical data. Claims that cannot be empirically verified are considered outside the domain of political science. Verification therefore became an important criterion for distinguishing scientific political inquiry from purely speculative or philosophical discussion.
Emphasis on the conscious use of sophisticated, precise, and rigorous research tools and procedures to collect and analyze data. This included surveys, interviews, content analysis, and statistical methods. The development of such techniques allowed researchers to study large populations and compare political behaviour across different groups, regions, and political systems.
1A strong preference for measuring and quantifying data whenever possible to enable more precise analysis and the use of statistical tools. Quantification allowed political scientists to convert political attitudes and behaviour into measurable variables. For example, political participation could be examined through voting rates, membership in political organizations, frequency of political activity, or responses to survey questions.
The attempt to separate ethical or normative questions (values) from empirical observation and analysis (facts). The goal was to conduct value-free research. Behaviouralists maintained that the researcher should attempt to minimize personal political preferences while collecting and interpreting empirical evidence. This principle later became one of the major targets of post-behaviouralist criticism.
Research should be systematic and theory-oriented. Data collection should be guided by a theoretical framework, and the findings should contribute to building broader theories. Behaviouralists therefore wanted political research to move beyond isolated observations and develop cumulative knowledge in which new studies could confirm, modify, or challenge existing explanations.
A commitment to the development of fundamental scientific knowledge about politics, even if it does not have immediate practical applications. The belief that applied science follows from pure science. Behaviouralists considered the development of reliable knowledge to be an important objective in itself, arguing that practical applications could subsequently emerge from improved understanding.
The primary goals of the behaviouralist movement were to:
By adopting methods and principles similar to those in the natural sciences, aiming for objective, verifiable knowledge. Behaviouralists sought to establish clear research procedures through which political claims could be tested against empirical evidence.
To move beyond isolated case studies and descriptive accounts towards generalizable theories that could build upon each other. Each new investigation was expected to contribute to the wider theoretical understanding of political behaviour.
To identify patterns that could allow for forecasting political outcomes. Prediction was considered an important indication that political science had discovered meaningful regularities in political behaviour, although the ability of behaviouralism to achieve reliable prediction later became a subject of criticism.
To introduce more analytical precision and methodological stringency into political inquiry. Behaviouralists emphasized clear concepts, measurable variables, systematic evidence, and careful research procedures in order to reduce vague or purely speculative political analysis.In addition, behaviouralism aimed to make political science more comparative and explanatory. Instead of studying political institutions separately, researchers could compare political behaviour across countries, social groups, and political systems. This comparative orientation contributed significantly to the development of modern comparative politics and empirical political research.
Despite its transformative impact, behaviouralism faced significant criticism, particularly from the late 1960s onwards, leading to the "post-behavioural revolution". Critics did not necessarily reject empirical research itself; rather, they challenged the claim that empirical and quantitative methods alone could provide a complete understanding of political life.
The insistence on strict value neutrality was criticized for making political science irrelevant to pressing social and political problems (e.g., civil rights, Vietnam War). Critics argued that research choices inherently involve values, and ignoring them could lead to implicit support for the status quo. They maintained that political science should not merely explain political behaviour but should also address major problems confronting society.
Accused of reducing complex political phenomena (like power, justice, or ideology) to merely observable behaviors, thereby losing deeper meaning, historical context, and the normative dimensions of politics. Concepts such as justice, freedom, legitimacy, and power cannot always be fully understood through numerical indicators alone. Critics therefore argued for a broader conception of political inquiry.
Its focus on contemporary, quantifiable data often led to a neglect of historical context, institutional development, and the long-term evolution of political systems. Political institutions and behaviours are frequently shaped by historical experiences, traditions, conflicts, and patterns of development. Ignoring these factors could produce incomplete explanations.
Critics argued that the emphasis on easily quantifiable data led scholars to study trivial or less significant aspects of politics, while ignoring more profound but harder-to-measure phenomena. Excessive concentration on measurement could encourage researchers to choose questions simply because they were easy to quantify rather than because they were politically important.
The methods and theories developed in the context of stable Western democracies might not be universally applicable or appropriate for understanding politics in diverse cultural and political settings. Political behaviour varies according to historical, cultural, institutional, and socio-economic circumstances. Therefore, theories developed in one political context could not automatically be generalized to all societies.
Despite its strong emphasis on prediction, behaviouralism often struggled to accurately predict major political events or social changes. Political behaviour is influenced by numerous interacting factors, and unexpected events can alter political outcomes. This demonstrated the difficulty of treating political behaviour as completely predictable.
1. Some argued that by focusing on observable behavior within existing systems, it implicitly accepted and reinforced the status quo, failing to challenge power structures or advocate for transformative change. By concentrating primarily on how political systems functioned rather than how they ought to function, behaviouralism was accused of limiting the critical role of political science.
While the extreme form of behaviouralism as a dominant paradigm began to wane by the late 1960s (partly due to self-criticism from within, notably by David Easton himself, who called for a "post-behavioural revolution"), its impact on political science is undeniable and enduring. The decline of behaviouralism did not mean a return to the complete dominance of traditional political theory. Instead, political science gradually moved towards a broader methodological pluralism in which empirical, institutional, historical, comparative, and normative approaches could coexist.
Behaviouralism irrevocably raised the standards for methodological sophistication and empirical analysis in political science. Researchers became more disciplined in data collection, measurement, and statistical inference. Concepts such as research design, sampling, operationalization, hypothesis testing, and systematic comparison became increasingly important in political research.
It led to a greater emphasis on gathering and analyzing empirical data, transforming political science into a more evidence-based discipline. Contemporary political scientists routinely use surveys, election data, statistical models, experiments, interviews, and other forms of empirical evidence to investigate political questions.
It fostered closer ties with other social sciences, enriching theoretical perspectives and methodological toolkits. Psychology contributed to the study of political attitudes and decision-making, sociology contributed to the study of social groups and political participation, while economics contributed analytical models for understanding political choices and institutions.
The criticisms against behaviouralism led to **post-behaviouralism**, which sought to retain the methodological rigor of behaviouralism while re-emphasizing the importance of values, context, relevance, and normative concerns. Post-behaviouralism aimed for a synthesis, acknowledging that "behavioral science ought to be and can be more relevant to the needs of society." It therefore attempted to combine scientific research with a greater concern for political relevance and social problems.
Mainstream political science today is largely a product of this evolution. While few identify as "pure behaviouralists," the commitment to empirical verification, systematic research design, and data analysis derived from the behavioural revolution remains central to most contemporary political science research, alongside a renewed appreciation for historical context, institutional analysis, and normative theory.
The behavioural revolution also contributed to the professionalization of political science research. Political scientists increasingly developed specialized research methods and used systematic evidence to evaluate competing explanations. Political behaviour, public opinion, elections, political participation, political communication, and comparative political analysis subsequently became established areas of research.
In essence, behaviouralism transformed political science by pushing it towards a more scientific and empirical footing. While its initial extremes were later tempered, its core contributions to methodological rigor continue to shape how political phenomena are studied and understood. Its greatest contribution was not the complete replacement of traditional political science but the expansion of the discipline's methodological possibilities. Contemporary political science consequently combines behavioural insights with institutional, historical, comparative, and normative approaches, creating a broader and more pluralistic discipline.
