Lijphart 1971 - Comparative Politics and the Comparative Method

The Methodological Awareness Gap in Comparative Politics

The article "Comparative Politics and the Comparative Method" by Arend Lijphart discusses the lack of methodological awareness among students of comparative politics and emphasizes the need for conscious thinking in the field. The article aims to analyze the strengths and potentialities of the comparative method in political inquiry, while also addressing its weaknesses and limitations.

Comparative Politics: Unveiling the True Significance of the Comparative Method

The text discusses the various meanings attached to the terms "comparison" and "comparative method" in the literature of comparative politics. It distinguishes the comparative method as one of the basic methods, not just a vague term symbolizing research interests, and not the scientific method. The text highlights the importance of establishing general empirical propositions through comparison, and distinguishes the comparative method from the scientific approach.

"The Comparative Method in Political Science: Uncovering Empirical Relationships and Contrasting with Experimental and Statistical Approaches"

The comparative method in political science has been discussed by various scholars, including Almond, Lasswell, and Eisenstadt. It is considered a broad-gauge, general method rather than a specialized technique, and is used to discover empirical relationships among variables. The method is distinct from measurement techniques, and understanding its nature involves comparing and contrasting it with other methods like experimental and statistical approaches.

"The Significance of the Comparative Method in Anthropology"

The text discusses the comparative method in anthropology, contrasting it with experimental and statistical methods. It emphasizes the importance of establishing general empirical relationships among variables and controlling for other variables, asserting that the two elements are inseparable. The experimental method is considered the most ideal for scientific explanation, as it uses two equivalent groups to compare and attribute differences to a specific stimulus.

Research Methods in Political Science: Evaluating Experimental, Statistical, and Case Study Approaches

The text discusses various research methods, including experimental, statistical, and case study methods, commonly used in political science. It highlights that the experimental method is considered the strongest due to its ability to establish controlled relationships among variables, while the statistical method is an approximation of the experimental method. The case study method is mentioned briefly but discussed below.

The Limitations of Control in Research Methods

The text discusses the limitations of control in various research methods, including experimental, statistical, and comparative methods. It highlights that even the experimental method cannot guarantee complete control due to uncertainties about group characteristics. The comparative method is more similar to statistical methods, but with a smaller number of cases, it may not allow for systematic control by means of partial correlations. The difference between statistical and comparative methods depends solely on the number of cases available.

The Limitations and Importance of the Comparative Method in Social Sciences

The text discusses the limitations of the comparative method in social sciences, emphasizing that it is not an adequate substitute for the experimental method. It highlights the importance of controlling for "forcing variables" and controlling the time variable in establishing causal relationships. The panel method is mentioned as a means of approximating this control in statistical design. The comparative method is considered as a distinct method, particularly when dealing with a small number of cases, and it is suggested that a combination of statistical and comparative methods is appropriate for situations with an intermediate number of cases.

The Challenges and Possibilities of the Comparative Method in Social Science Research

The comparative method in social science research faces challenges such as many variables and a limited number of cases. The limitations of this method should be recognized, but its possibilities should also be taken advantage of. The method can be used to give general propositions, account for facts, and provide insight into large-scale statistical comparison. However, it is often beneficial for researchers to use statistical or experimental methods rather than comparative methods when possible.

The Importance of Thorough Comparative Analysis in Research

Comparative analysis serves as a first stage in research, generating hypotheses that are later tested through statistical analysis. Cross-national research can be either macro-hypothesis or micro-replication-focused, with the former often relying on the comparative method and the latter potentially using both comparative and statistical methods. Both stages of research should be thorough and avoid the fallacy of giving too much importance to negative findings.

The Importance of Probabilistic Generalizations in Scientific Search: Minimizing the Impact of Deviant Cases

Probabilistic generalizations should be the aim in scientific search, with the understanding that deviant cases can weaken, but not necessarily invalidate, a hypothesis. Comparative analysis of a small number of cases can be problematic due to the significance of a single deviant case, whereas statistical analysis of many cases can tolerate one or two deviations. Ensuring a larger sample size can help minimize the issue of "many variables, small N" in comparative studies.

Unraveling the Challenges of Comparative Politics: A Confrontation with Empirical Data

Modern comparative politics has progressed by creating universally applicable vocabularies of basic politically relevant concepts, such as Parsonian theory and Almond's functional approach. This restatement of variables in comparable terms makes many previously inaccessible cases available for analysis and extends the analysis geographically and historically. However, the test of the hypothesis through confrontation with empirical or historical data remains inconclusive.

Analyzing Similarities and Differences: Challenges and Methods in Comparative Politics

Comparative politics aims to unite diverse political systems by analyzing their similarities and differences. To enhance comparative analysis, methods such as reducing property-space, focusing on comparable cases, and combining variables can be employed. However, challenges include the lack of information about political systems and balancing the risk of sacrificing valuable information.

"The Comparative Method in Political Science: Reducing Variables and Studying Relationships"

The comparative method in political science involves a focus on a limited number of comparable cases, aiming to reduce the number of variables and study their relationships under controlled conditions. This method differs from the "small N" problem and is compatible with other recommendations. It includes the "method of difference," comparing instances with and without a phenomenon, and the "method of concomitant variations," a more sophisticated version of the method of difference, observing more variables.

"Exploring Concomitant Variations and the Potential of the Area Approach"

The text discusses the method of concomitant variations, which is considered a systematic formulation of the modern comparative method. It involves observing and measuring quantitative variations of operative variables and relating them to each other. However, critics argue that it cannot be applied in the social sciences due to the difficulty in finding sufficiently similar cases. The area approach is suggested as a potential solution due to the common characteristics that areas tend to have, which can be used as controls for comparison.

The Value and Challenges of Area Studies in Comparative Politics

Area studies are considered essential for comparative government, offering opportunities for fruitful intra-area comparisons. However, the value of area studies in comparative politics has been challenged, arguing that mere geographic proximity is not the best basis for comparison and that comparability is imposed by the observer's perspective. Some scholars assert that socio-culturally similar groupings of countries can offer better comparisons, while others emphasize the importance of contemporary comparisons.

"Embracing Partial Generalizations: Advantages of the Area Approach in Comparative Politics"

The text discusses the importance of partial generalizations in comparative politics and argues against giving up the area approach. It emphasizes the need for crucial controls and suggests that smaller areas like Scandinavia and Anglo-American countries may offer more advantages. Alternatively, diachronic comparative analysis, comparing a single country at different times, can also be effective in establishing better controls, as demonstrated in Charles E. Frye's study on Germany under the Weimar and Bonn Republics.

"Unleashing the Power of Intra-Unit Comparisons in Comparative Analysis"

This text discusses the importance of utilizing intra-unit comparisons in comparative analysis, as they can take advantage of similar national characteristics as controls. This method can be applied to political systems and offers a more fruitful approach than overall national comparisons. The text suggests that combining intranation and internation comparisons may be particularly promising, as it allows for testing theories about differences between similar sectors of two societies.

The Challenges and Limitations of Comparative Research in Political Science: Overcoming Bias and Emphasizing Theoretical Parsimony

The text discusses the challenges and limitations of comparative research in political science. It highlights the dangers of "whole-nation" bias and suggests focusing on key variables to avoid being overwhelmed by large numbers of variables. The text also argues against "configurative" or "contextual" analysis and emphasizes the importance of theoretical parsimony in comparative analysis.

Comparative Analysis in Political Science: Challenges, Potential, and the Importance of Key Variables

This text discusses the challenges and potential of applying comparative analysis in political science. It highlights the need for simplification and focusing on key variables to manage the vast amount of data and variables involved. It also suggests anthropology as a useful model for comparative studies, and emphasizes that comparative politics is distinct from comparison as a method.

The Comparative Method: A Quantitative Historical Comparison

The text discusses the comparative method in political research, focusing on the method of "quantitative historical comparison." It highlights the testing of hypotheses by comparing two eras with different variables, and emphasizes the method's connection to the case study method. The case study method allows for intensive examination of a single case, but its scientific status is somewhat ambiguous due to its focus on a single case.

The Importance of Case Studies in Political Science and their Diverse Types

The text discusses the importance of case studies in political science and distinguishes six types: atheoretical, interpretative, hypothesis-generating, theory-confirming, theory-infirming, and deviant. It argues that purely descriptive case studies, though lacking direct theoretical value, can contribute indirectly to theory-building through secondary analysis. It also emphasizes that actual case studies likely fit multiple types to some extent.

Exploring the Spectrum: Understanding Different Approaches to Case Studies in Political Science

The text discusses various types of case studies in political science, including atheoretic, interpretative, hypothesis-generating, theory-confirming, and theory-infirming studies. Interpretative studies apply generalizations to specific cases, while hypothesis-generating studies develop new theories in areas with limited existing theories. The remaining types of case studies focus on either confirming or refuting established generalizations.

"Exploring the Value of Case Studies in Theory Building: Hypothesis Generation and Deviant Cases"

The text discusses the value of different types of case studies in building theory, such as hypothesis-generating and deviant case studies. Deviant case studies, in particular, can refine and sharpen existing hypotheses and contribute to the development of stronger theories. The main functions of case studies are to generate new hypotheses or to refine and strengthen existing ones.

Analyzing Deviant Cases: Refining Generalizations in Comparative Research

Robert M. Marsh's "specification" is a method of refining generalizations through analyzing deviant cases in comparative research. It's crucial to consider the different types of cases and their varying contributions to theory-building. Deviant case analysis, like the comparative method, can increase analytical power when its position within variables and relative to other cases is clearly defined.

Refining Political Analysis: Overcoming Limitations in Comparative and Case Study Methods

The text discusses the limitations of the comparative method and the case study method in political analysis. It critiques Eckstein's analysis of the Norwegian case, finding that the perfect fit of the facts to his congruence theory does not contribute to its refinement. It suggests that the investigator's task is to apply these methods in a way that minimizes their weaknesses and capitalizes on their strengths for effective political inquiry.

Exploring Plausibility: Hypothesis-Strengthening Studies in Britain, Germany, and Norway

The cases of Britain, Germany, and Norway are not conclusive theories but hypothesis-strengthening or "plausibility probe" studies. Eckstein's "A Theory of Stable Democracy" (1961) explores these possibilities.

Comparative Politics and the Comparative Method

•Comparative politics is a field within political science that focuses on the methodological aspects of analysis rather than specific subjects.

•The term "comparative politics" does not specify the content of the analysis.

•Many students of comparative politics lack awareness and understanding of empirical science and rely on quantitative research techniques without applying logical and methodological approaches.

•The comparative method, while basic and simple, is often unconscious in its application due to a lack of a defined methodology.

•The purpose of the paper is to promote conscious thinking in comparative politics and highlight the strengths and limitations of the comparative method.

Comparative Politics and the Comparative Method

•The field of "political behavior" is a relatively new field, with the term behaviorism representing a general approach or set of methods.

•In comparative politics literature, the terms "comparison" and "comparative method" have a variety of meanings.

•The comparative method is defined as one of the basic methods of establishing general empirical propositions, alongside experimental, statistical, and case study methods.

•It is a method, not just a vague symbol of research interests, and not a special set of substantive concerns.

•The comparative method is narrower in scope than the scientific method, which includes a comparative approach.

•Gabriel A. Almond equates the comparative method with the scientific method in the study of politics.

•Arthur L. Kalleberg emphasizes the logic of comparison as a methodological note in the comparative study of political systems.

Comparative Method in Political Science

•The comparative method is a method of discovering empirical relationships among variables in political science.

•It should not be confused with a method of measurement.

•The comparative method involves nonmetrical ordering or ordinal measurement.

•It is important to distinguish between method and technique in the context of the comparative method.

•The comparative method is a broad-gauge, general method and not a narrow, specialized technique.

•It can be considered as a basic research strategy, not just a tactical aid to research.

•The nature of the comparative method can be understood by comparing and contrasting it with the experimental and statistical methods.

The Comparative Method and Other Research Strategies

•The comparative method in anthropology does not have a distinctive methodology but rather focuses on comparisons within the field.

•There are three fundamental strategies of research: the comparative method, the experimental method, and the statistical method.

•All three methods aim at scientific explanation, which involves establishing empirical relationships among variables while controlling for other variables.

•The ceteris paribus condition, or holding all other variables constant, is crucial for empirical generalizations.

•The experimental method uses two equivalent groups, one exposed to a stimulus and the other not, to compare and attribute differences to the stimulus.

•Deliberate randomization can achieve equivalence between the groups.

•The experimental method is considered the most ideal for scientific explanation but has limitations.

•The comparative method can be discussed in relation to other basic methods such as the experimental method.

•Other general discussions of the comparative method can be found in various sources.

Research Methods in Social Science

•The case study method will be discussed below.

•The experimental method is limited in political science due to practical and ethical impediments.

•An alternative method is the statistical method, which involves manipulating observed data to discover controlled relationships among variables.

•Partial correlations are used to handle the problem of control in the statistical method.

•Cross-tabulation is a basic research procedure that is automatically applied in empirical research to consider the role of further variables.

•The statistical method is an approximation of the experimental method and has essential logical functions but is not as strong due to its inability to handle certain problems.

Control in Research Methods

•Control in research methods refers to the ability to manage and account for variables that may influence the outcome of a study.

•Partial correlations are a method of control that can account for known or suspected key variables, but cannot control for all other variables.

•Control by means of partial correlations does not consider measurement error or unique factor components.

•Partial correlations also do not resolve the issue of the codiffusion of characteristics, known as "Galton's problem."

•The experimental method is not a perfect solution for control, as it is difficult to ensure that groups being compared are truly alike in every respect.

•The experimental method is considered the closest approximation to the ideal of control.

•The statistical method is an approximation of the experimental method, but not an equivalent.

•The comparative method shares similarities with the statistical and experimental methods but deals with a smaller number of cases.

•The comparative method lacks the ability for systematic control through partial correlations due to the limited number of cases.

•The decision to use the comparative method is based on the feasibility of establishing credible controls with the available number of cases.

•The line between the statistical and comparative methods depends on the number of cases being analyzed.

•Randomization can be used in the experimental method to ensure equivalent groups.

Comparative Method in Social Science Research

•The use of the comparative method is discussed as a distinct method, although it can be argued that it is an aspect of a single method.

•The comparative method is often used in research situations with an intermediate number of cases, where a combination of statistical and comparative methods is appropriate.

•In the field of comparative politics, where national political systems are studied, the number of cases is restricted, necessitating the use of the comparative method.

•The comparative method is not equivalent to the experimental method but serves as an imperfect substitute.

•Limitations of the comparative method exist, but they can be overcome with awareness and understanding.

The Comparative Method: Weaknesses and Strengths

•The principal problems facing the comparative method are many variables and a small number of cases.

•These two problems are closely interrelated.

•Many variables is a common issue in social science research, regardless of the method used.

•A small number of cases is unique to the comparative method and makes handling many variables more difficult.

•It is generally recommended to use the statistical or experimental method instead of the comparative method, if possible.

•However, due to limited time, energy, and financial resources, intensive comparative analysis of a few cases may be necessary.

Comparative Analysis in Cross-National Research

•The comparative analysis is considered more promising than a superficial statistical analysis of many cases.

•Comparative analysis should be regarded as the first stage of research, where hypotheses are formulated.

•Statistical analysis is the second stage, where hypotheses are tested in a large sample size.

•In cross-national research, there are two aims: testing "macro hypotheses" on the interrelations of structural elements and "micro replications" to validate propositions in different settings.

•The comparative method is commonly used in cross-national research with limited cases, while the statistical method can be used when focusing on individuals as units of analysis.

•The use of "paired comparisons" is recommended in cross-national research.

•Negative findings should not be given excessive significance in the comparative method to avoid the fallacy of disregarding hypotheses based on one deviant case.

Challenges of Comparative Analysis

•When conducting a scientific search, it is important to select cases systematically and aim for probabilistic generalizations rather than universal ones.

•Rejecting a hypothesis based on a single deviant case is uncommon when using statistical methods with a large sample. However, in comparative analysis of a small number of cases, even one deviant case can have a significant impact.

•The presence of one or two deviant cases is less problematic in a statistical analysis of many cases compared to a comparative study of a few cases.

•It is a mistake to reject a hypothesis simply because one can think of a contrary case. Deviant cases weaken a probabilistic hypothesis but can only invalidate it if they occur in sufficient numbers to eliminate the hypothesized relationship completely.

•Increasing the number of cases is one way to minimize the "many variables, small N" problem in comparative analysis. Even a small enlargement of the sample improves the chances of conducting a successful analysis.

Comparative Politics and the Comparative Method

•Modern comparative politics has made progress in creating universally applicable vocabularies of basic politically relevant concepts.

•Restating variables in comparable terms allows for the analysis of previously inaccessible cases.

•Geographic extension of analysis should be considered, as well as the inclusion of historical cases for longitudinal extension.

•The promise of discovering universal laws through global and longitudinal comparisons led to the enthusiasm for the comparative method.

•Investigating all available cases is necessary to ensure the representativeness of a limited sample.

•General concepts not tied to particular cultures are necessary for comparative politics.

•Critiques of recent attempts at terminological innovation in comparative politics are available.

•Comparative analysis was recognized as a significant achievement in the field of comparative politics a century ago.

Comparative Politics and the Comparative Method

•Comparative politics is a field that explores connections and relationships between different political systems.

•Edward A. Freeman emphasized the importance of comparative politics in understanding the global political landscape and the interdependence of different nations.

•Despite its potential, the field of comparative politics has not fully achieved its goals.

•Extending comparative analyses geographically and historically can provide valuable insights.

•However, there is often a lack of information about political systems, especially historical cases.

•To overcome limitations in sample size, it is possible to combine variables with similar underlying characteristics, reducing the "property-space" of the analysis.

•Factor analysis is a useful technique for achieving this objective.

•Reducing the number of categories or classes in variables can also increase the number of cases per cell.

•However, this sacrifices some information at the investigator's disposal and should be used with caution.

•In comparative analysis, "comparable" cases refer to those that are similar in many important characteristics but differ in the variables being studied.

•Such cases offer excellent opportunities for the application of the comparative method.

Strengthening the Comparative Method

•The movement from hypothesis to theory is contingent upon analysis of the total range of political systems.

•It is often more practical to prioritize the focus on a limited number of comparable cases and the discovery of partial generalizations.

•The focus on comparable cases aims to reduce the number of operative variables and study their relationships under controlled conditions.

•This approach addresses the problem of "many variables" and differs from the first recommendation that focuses on "small N."

•The use of comparable cases usually decreases the number of cases subject to analysis.

•The method of difference involves comparing instances where a phenomenon does occur with instances where it does not, with other similarities.

•The method of concomitant variations is a more sophisticated version of the method of difference.

•The method of concomitant variations observes the presence or absence of a phenomenon alongside other variables.

Mill's Method of Concomitant Variations and the Utility of the Area Approach

•Mill's Method of Concomitant Variations is a systematic formulation of the modern comparative method.

•The method requires keeping all other factors constant and observing and measuring quantitative variations of the operative variables.

•Concomitance of variations must be proven by the Method of Difference to infer causation.

•Mill believed that the method could not be applied in the social sciences due to the difficulty in finding sufficiently similar cases.

•Durkheim agreed with Mill's negative judgment and stated that the absolute elimination of adventitious elements is unattainable.

•Objections to the method are based on a too exacting scientific standard.

•The area approach is well-suited for applying the comparative method as areas tend to have common characteristics that can be used as controls.

•Opinions on the utility of the area approach vary.

•The era approach may be preferable to longitudinal analysis when maximizing comparability is a priority.

The Value and Obsolescence of Area Studies in Comparative Government

•Gunnar Heckscher argues that area studies are essential in comparative government and that reducing the number of variables can lead to more meaningful comparisons.

•Roy C. Macridis and Richard Cox suggest that if areas have both political and non-political similarities, the area concept can be valuable for comparing political processes within the area.

•Dankwart A. Rustow disagrees and claims that area studies are almost obsolete, as geographic proximity does not necessarily provide the best basis for comparison, and comparability depends on the observer's perspective.

•There are socio-culturally similar groupings of countries that correspond closely to areas or regions of the world, as discovered by Bruce M. Russett through factor analysis.

•C. E. Black states that comparing contemporary events and institutions is more valuable than comparing societies from different time periods, especially when the societies have reasonably similar problems.

•Dell G. Hitchner and Carol Levine criticize area studies for their method of delimitation.

Comparative Politics and the Comparative Method

•The text discusses the need for partial generalizations as a first step in comparative politics.

•The area approach in comparative politics should be an aid to the comparative method, not an end in itself.

•The area approach should be used selectively, where it offers the possibility of establishing crucial controls.

•The comparative analysis of a single country diachronically can maximize comparability.

•Charles E. Frye's study of the empirical relationships among the party system, the interest group system, and political stability in Germany under the Weimar and Bonn Republics is an example of diachronic comparative analysis.

Comparative Analysis in Social and Political Studies

•In order to enhance comparability in cross-national studies, it is important to focus on intranation analysis instead of international comparisons, as similar national characteristics can serve as controls.

•Intration comparison allows for inter-unit differences to be held constant, providing a clearer understanding of operative factors within a specific context.

•Combining intranation and internation comparisons can be a promising approach, comparing sectors of two societies that have a greater number of characteristics in common while differing on crucial ones.

•This approach can be particularly fruitful in political studies, such as comparing the cabinet and parliament systems in different countries.

•The postwar division of Germany offers the opportunity to analyze the effects of democratic versus totalitarian development against a similar cultural and historical background.

Comparative Political Analysis

•The text references a journal article titled "Revolution, Re-construction," Encounter, which was published in April 1964.

•Sylvia L. Thrupp's article "Diachronic Methods in Comparative Politics" is mentioned as a source in the book The Methodology of Comparative Research edited by Holt and Turner.

•Heckscher's work is cited on page 69, and Heinz Eulau's article "Comparative Political Analysis: A Methodological Note" in the Midwest Journal of Political Science is referenced.

•Rokkan warns against the "whole-nation" bias in comparative research.

•Smelser's work is cited on page 115.

•Juan J. Linz and Amando de Miguel suggest focusing on comparing similar entities in the context of presidential systems of government, using the examples of Manitoba and North Dakota as more suitable for comparison than Great Britain and the United States.

•The comparative analysis should prioritize key variables and avoid being overwhelmed by too many variables.

•The nature of the comparative method and its limitations argue against "configurative" or "contextual" analysis that considers factors from the whole social order.

•Lasswell calls for exploring more variables and continually scanning the entire context in comparative analysis.

•Comparative politics should strive for parsimony, avoiding the trap of including all variables and adopting a realistic approach.

Comparative and International Politics

•"Con- figurative" analysis is different from the traditional single-country approach.

•Joseph LaPalombara's "segmented approach" focuses on middle-range propositions concerning partial systems.

•Eckstein calls for greater manageability of the field, emphasizing simplification.

•The comparative method is most fruitful in anthropological research due to the lesser number of variables in primitive societies.

•Political science can approximate the quasi-experimental approach of anthropology by focusing on key variables in comparative studies.

•Comparative politics as a field is not limited to the comparative method.

•James N. Rosenau's study examines the influence of individual and role variables on the behavior of U.S. senators in two distinct eras.

•The study argues that the international environment and the behaviors of the secretaries of state were similar in the two eras.

•The comparative method can be applied in other fields and disciplines.

•Robert A. Dahl's book, "Political Oppositions in Western Democracies," is referenced as an example of macrotheories and micro applications in comparative politics.

Comparative Method and Case Study Method in Political Science

•The author discusses a method called "quantitative historical comparison" that involves comparing two eras or cases that are essentially comparable in all respects except for the variables being examined. The variables are operationally defined in quantitative terms, and the method is considered a special form of the comparative method.

•The author emphasizes that the comparative method is not complete without considering the case study method. While the comparative method can be applied to relatively few cases, the case study method focuses on a single case and allows for intensive examination, even with limited resources.

•The case study method is somewhat ambiguous in terms of its scientific status because science is a generalizing activity. A single case cannot be the basis for a valid generalization or the ground for disproving an established generalization.

•However, case studies can indirectly contribute to the comparative method by providing additional evidence or insights when the findings are not clear enough to confirm or negate hypotheses. This may involve comparing a third or more comparable periods.

Types of Case Studies and Their Importance in Theory-Building

•There are six types of case studies that can be distinguished: ideal types, atheoretical case studies, interpretative case studies, hypothesis-generating case studies, theory-confirming case studies, theory-infirming case studies, and deviant case studies.

•Atheoretical case studies are entirely descriptive and do not move in a theoretical vacuum. They are neither guided by established or hypothesized generalizations nor motivated by a desire to formulate general hypotheses.

•The first two types of cases belong to the category of being selected for analysis because of an interest in the case per se.

•Theoretical case studies are the traditional single-country or single-case analyses and are purely descriptive. They do not have direct theoretical value but contribute indirectly to theory-building by providing basic data.

•The development of comparative politics is hindered by a lack of information about the world's political systems, thus descriptive case studies have great utility as data-gathering operations.

•The atheoretical case study and other types of case studies are ideal types, but actual case studies often fit multiple types to some extent.

•The cumulative effect of atheoretical case studies can lead to fruitful generalization if followed by a theoretically oriented secondary analysis of the collected data.

Types of Case Studies in Political Science

•Interpretative case studies are selected for analysis based on interest in the specific case rather than the formulation of general theory. These studies make use of established theoretical propositions and aim to shed light on the case, rather than improve generalizations.

•Empirical theory aims to make interpretative case studies possible, but such studies are rare due to limited theoretical development in political science.

•Example of an interpretative case study: Michael C. Hudson's case study of Lebanon, which examines the country's socioeconomic and political development in the context of existing development theories.

•Hypothesis-generating case studies aim to formulate definite hypotheses to be tested among a larger number of cases. They are valuable for developing theoretical generalizations in areas where no theory exists yet.

•Theory-confirming and theory-infirming case studies analyze single cases within the framework of established generalizations. These studies test existing theories against specific cases and may reveal exceptions or demonstrate the validity of the generalization.

Types of Case Studies in Comparative Analysis

•A case study is a test of a proposition in comparative analysis, which can either confirm or infirm the proposition.

•Case studies can either strengthen or weaken generalizations, depending on whether they support or contradict the proposition.

•Theory-confirming case studies strengthen the proposition, but only to a certain extent if it is already supported by a large number of cases.

•Theory-infirming case studies only marginally weaken generalizations.

•Case studies that are extreme on one of the variables are referred to as "crucial experiments" or crucial tests of the propositions.

•Deviant case analyses focus on single cases that deviate from established generalizations.

•Deviant case studies aim to uncover additional variables or refine the definitions of variables.

•Deviant case studies weaken the original proposition but may suggest a modified and stronger proposition.

•The validity of the modified proposition must be established through further comparative analysis.

•The hypothesis-generating case study generates new hypotheses.

•The deviant case study refines and sharpens existing hypotheses.

Deviant Case Analysis and the Comparative Method

•Deviant case analysis is a process of refining generalizations.

•Robert M. Marsh refers to this process as "specification."

•"Specification" is discussed in Marsh's article "The Bearing of Comparative Analysis on Sociological Theory."

•Conrad Phillip Kottak argues against regarding specification as "the garbage bin" of comparative research.

•Milton M. Gordon also explores the relationship between sociological law and the deviant case.

•Andre J. F. Kobben discusses the logic of cross-cultural analysis and why exceptions are important.

•Deviant case analysis can be seen as similar to an "experimental group" in comparison with a "control group."

•The closer deviant case analysis aligns with statistical and experimental methods, the more analytical power it has.

•The case study method also gains analytical power when it incorporates deviant case analysis.

•Clear definition of the deviant case's position on variables and its relation to other cases is necessary for successful case analysis.

•Different types of cases have unequal potential contributions to theory-building.

•Selection and analysis of a single case should take into account the different types of cases.

•Eckstein's case study of Norway illustrates shortcomings in analyzing a single case.

•Eckstein argues that Norway deviates from Truman's proposition on "overlapping memberships."

•However, Eckstein's study fails to compare Norway's divisions with cleavages in other countries, weakening the analysis.

•Deviant findings can be used to refine existing propositions.

The Norwegian Case Study and the Limitations of Comparative Methods

•The Norwegian case study analyzed by Eckstein is not considered a deviant case study, but rather a theory-infirming one.

•Eckstein's analysis focuses on the congruence theory, which states that governments tend to be stable if there is considerable resemblance between governmental and social authority patterns.

•In the Norwegian case, both governmental and social patterns of authority are strongly democratic and highly congruent, which perfectly fits the congruence theory.

•However, the perfect fit of the Norwegian case does not contribute to the refinement of the theory, as complete congruence is not required for stable democracy.

•Eckstein acknowledges the need for further research on the questions of how much disparity can be tolerated and how degrees of congruence and disparity can be measured.

•Eckstein's selection of the Norwegian case is considered unlucky for the development of his congruence theory.

•The case study method could have been used to analyze the Norwegian case in terms of Truman's theory of overlapping memberships, but this opportunity was missed.

•The comparative method and the case study method have limitations, but when applied effectively, they can be useful instruments in scientific political inquiry.

Hypothesis vs Theory in Case Studies

•In the context of two cases (Britain and Germany), the discussion revolves around a hypothesis rather than an established theory.

•The case study of Norway is not a hypothesis-generating study either.

•Suggestions are made for alternative labels, such as calling it a "hypothesis-strengthening" case study or a "plausibility probe" according to Eckstein.

•Eckstein's work, titled "A Theory of Stable Democracy," is referenced as a research monograph from 1961.
