Can the Same Research Method Be Used Under Different Paradigms?

Does a Research Method Come With Its Own Paradigm?

You plan to conduct interviews, so someone tells you the study must be interpretivist. You develop a questionnaire, so another source classifies the research as positivist. You combine interviews and statistical analysis, and suddenly pragmatism appears to be mandatory.

These associations are understandable. Particular methods have developed strong affinities with particular research traditions. Experiments and standardized measurement fit comfortably within positivist and postpositivist inquiry. In-depth interviews and ethnographic observation are closely associated with interpretive and constructivist research.

But affinity is not ownership.

A research method is a procedure for generating or analyzing evidence. A paradigm concerns broader assumptions about reality, knowledge, inquiry, and sometimes values. The same method can therefore be used differently under different paradigms because its philosophical meaning depends on what researchers believe the evidence represents, why they are generating it, how they analyze it, and what conclusions they intend to support.

This does not mean any method fits any paradigm equally well. Philosophical flexibility still requires methodological coherence.

Yes, Methods Can Cross Paradigmatic Boundaries

Why Methods Do Not Belong Exclusively to Paradigms

Method, Methodology, and Paradigm Operate at Different Levels

Much of the confusion disappears once these concepts are separated.

A paradigm provides broad assumptions about inquiry. Methodology concerns the logic or strategy through which a research problem is investigated. Methods are the specific procedures used to generate or analyze evidence.

The levels interact, but they are not interchangeable.

This is why identifying a method does not automatically identify the paradigm. Morgan argues explicitly that although paradigms and methods can have affinities, there is no deterministic link forcing researchers using particular methods to adopt one particular paradigm.

An Interview Is Not Inherently Interpretivist

Interviews provide perhaps the clearest example.

An interpretivist researcher may interview participants because their meanings and interpretations are themselves central to the phenomenon. The interview becomes a context in which researchers seek to understand how participants make sense of experience.

A postpositivist researcher could interview people for a different reason. Participants' accounts might be treated as fallible evidence about barriers, behaviors, events, or processes that exist independently of the interview itself.

A critical realist researcher might use interviews to investigate experiences and processes that provide evidence about possible causal mechanisms, while recognizing that participants' own causal explanations are not necessarily identical to the mechanisms operating.

A transformative researcher might use interviews to center knowledge historically excluded from institutional decision-making and to investigate how power shapes experience.

Same broad method. Different epistemological roles.

A Survey Is Not Inherently Positivist

Surveys are strongly associated with positivist and postpositivist research because standardized questionnaires allow researchers to operationalize constructs, compare observations, estimate population characteristics, and test hypotheses.

But surveys can serve other purposes.

A pragmatic researcher may use a survey because decision-makers need population-level evidence about the scale of a practical problem.

A transformative researcher may use survey data to document structural disparities while critically examining whether existing categories represent marginalized populations appropriately.

A critical realist researcher may use survey associations to identify patterns requiring explanation rather than treating the measured relationship itself as the complete causal mechanism.

Even within one questionnaire, the philosophical interpretation of what a score represents can differ substantially.

Statistical Analysis Does Not Automatically Mean Positivism

A regression coefficient is a mathematical result. It does not announce its ontology when the software produces it.

A postpositivist researcher might interpret a coefficient as a fallible estimate of an empirical relationship, emphasizing uncertainty and competing explanations.

A critical realist might treat the relationship as an observed pattern potentially generated by deeper causal mechanisms.

A transformative researcher might use the same model to document inequity while questioning whether conventional categories conceal important structural processes.

A pragmatic researcher might use the estimate because it contributes information needed to make a consequential decision.

This is why quantitative research does not have to be positivist.

Qualitative Methods Do Not Automatically Mean Interpretivism Either

The reverse shortcut is equally problematic.

Interviews, observations, focus groups, documents, and qualitative coding have powerful affinities with interpretive and constructivist inquiry because they can preserve meaning, experience, language, and context.

Yet qualitative studies do not have to be interpretivist or constructivist. Qualitative evidence can contribute to postpositivist, pragmatic, critical realist, transformative, and other forms of inquiry.

Again, the question is what the evidence is being used to know.

The Method Stays the Same, but Its Epistemological Role Can Change

Suppose five researchers ask participants the same interview question:

"What influenced your decision to continue or leave your university program?"

The audio recording does not change its paradigm when moved from one row to another. What changes is the researcher's account of what the evidence can tell us and how it contributes to knowledge.

Paradigms Still Influence How Methods Are Designed

Saying that methods can cross paradigms does not mean their implementation remains identical.

An interpretivist interview may be deliberately open and responsive because the researcher wants participants' meanings to shape the conversation. A more structured postpositivist interview may emphasize consistency across participants because comparability is important.

A transformative interview process may give community members substantial influence over which questions are asked and how findings are interpreted. A critical realist interview may use theoretically informed follow-up questions to examine possible mechanisms and competing explanations.

Thus, the same method can cross paradigms while being adapted to the epistemological and methodological purposes of each.

Methods Are Not Completely Philosophically Neutral

There is an important qualification.

Rejecting fixed method-paradigm ownership does not require claiming that every method is philosophically neutral.

Methods embody assumptions and affordances. A standardized questionnaire constrains participants to predetermined categories. An open interview allows meanings to emerge in ways the researcher may not anticipate. An experiment deliberately creates control over conditions. Participant observation places the researcher inside a social setting.

Those characteristics make some methods more compatible with particular questions and philosophical purposes than others.

What Morgan rejects is a deterministic connection, not the existence of affinities.

Some Method-Paradigm Combinations Require More Justification

Suppose an interpretivist study seeks to understand how participants construct highly contextual meanings but relies entirely on a closed questionnaire containing predetermined response categories.

The combination is not automatically impossible. Perhaps the questionnaire has a specific role within a larger design.

But the researcher should explain how a method that restricts participants to predetermined categories can generate the contextual knowledge the interpretive question requires.

Likewise, a positivist researcher conducting entirely unstructured interviews should explain how the resulting interpretive evidence supports the objective, replicable knowledge claims being pursued.

The more tension exists between what a method affords and what a paradigm requires, the more methodological justification becomes necessary.

The Same Method Can Support Different Kinds of Causal Reasoning

Even causal methods illustrate the distinction.

A randomized experiment may be used within postpositivist research to estimate whether an intervention causes an average difference in an outcome under specified conditions.

A pragmatic researcher may use the same experiment because decision-makers need credible evidence about whether implementing the intervention improves outcomes.

A transformative researcher could use randomization to test whether an intervention reduces an inequity affecting a marginalized population.

A critical realist researcher might use experimental evidence as one component of a broader explanation concerning which mechanisms produce the effect and why effects vary across contexts.

The experimental design imposes important inferential constraints. It still does not settle every philosophical question surrounding what the causal effect means.

Methodological Rigor Also Changes With the Knowledge Claim

The standards used to judge a method should correspond to what researchers expect it to accomplish.

If interviews are intended to estimate the prevalence of an attitude in a national population, a small purposive sample will generally not support that inference.

If interviews are intended to develop contextual understanding of how people interpret an experience, statistical representativeness may not be the relevant criterion.

If interviews contribute evidence about a proposed critical realist mechanism, researchers need to explain how the accounts support that explanatory inference.

Methods therefore cannot be evaluated independently of the claims attached to them.

Software Does Not Determine Paradigm Either

NVivo does not make research constructivist. SPSS does not make it positivist. R does not have an epistemology. Neither does a spreadsheet, despite what a particularly philosophical pivot table might suggest.

Software performs analytical operations specified by researchers.

The paradigm is found in the assumptions governing why those operations are performed, what the resulting evidence represents, and how researchers move from analysis to knowledge claims.

Mixed Methods Makes This Issue Especially Visible

Mixed-methods research combines forms of inquiry historically associated with different paradigms, which made the method-paradigm relationship a major philosophical issue.

Mixed-methods scholarship now recognizes multiple philosophical stances for integration, including pragmatism, transformative approaches, dialectical pluralism, critical realism, and others.

This diversity would make little sense if quantitative and qualitative methods were permanently owned by incompatible paradigms.

Instead, researchers must explain how methods and philosophical assumptions relate within the particular study.

Methodological Flexibility Does Not Eliminate Alignment

If methods can cross paradigms, does paradigm-methodology alignment no longer matter?

It still matters.

Alignment should not be understood as a lookup table in which each paradigm permits only certain methods. It means that your assumptions about knowledge, methodological strategy, evidence, analytical procedures, and intended claims should form a defensible relationship.

The question is not "Is this method allowed under my paradigm?"

The better question is "Can this method generate the kind of evidence my research logic requires, and can I justify how I interpret that evidence?"

One Interview Method, Three Different Paradigmatic Uses

This is why describing your data-collection technique is not sufficient philosophical justification. The method tells readers what you did. The paradigm and methodology help explain what you believe doing it allows you to know.

Common Mistakes When Connecting Methods With Paradigms

Choose Methods for What They Can Contribute, Then Justify Their Philosophical Role

Do not ask only which methods are traditionally associated with your paradigm. Ask what evidence your research question requires.

The practical principle is straightforward: methods should be selected because they can generate evidence relevant to the question, then situated within a coherent account of what that evidence means and what conclusions it can support.
