Does Every Researcher Need to Identify a Research Paradigm?

Do You Really Have to Name a Research Paradigm?

You understand that research involves assumptions about reality, knowledge, evidence, and inquiry. But does that mean every researcher must choose a label such as postpositivist, constructivist, interpretivist, pragmatic, critical realist, or transformative and declare it in the methodology?

This question becomes especially confusing when published studies in your field rarely mention paradigms at all, yet a research-methods textbook or thesis template appears to expect one.

The distinction that helps is between having philosophical assumptions and explicitly naming a research paradigm. All research operates with assumptions about what can be investigated, what constitutes evidence, and what conclusions the evidence can support. Those assumptions may be implicit or explicit. Whether they need to be organized under a named paradigm and reported as such depends on the methodology, discipline, research purpose, genre, and institutional or publication expectations.

A paradigm should clarify your research logic. It should not become a compulsory label added merely because research appears more sophisticated with an "-ism" attached to it.

No, Not Every Study Needs an Explicit Paradigm Declaration

When Identifying a Research Paradigm Actually Matters

Every Study Has Assumptions, Even When No Paradigm Is Named

A researcher does not become philosophically neutral by omitting the word "paradigm."

Consider a study testing whether a teaching intervention improves examination performance. The researcher must still make assumptions about what achievement means, whether it can be represented adequately through the selected outcome, what counts as evidence of an intervention effect, how uncertainty should be handled, and what conclusions the design can support.

An ethnographic study has assumptions too. So does a randomized experiment, a phenomenological study, a regression analysis, a critical discourse analysis, and a mixed-methods evaluation.

Research paradigms make such assumptions more explicit by organizing ideas about reality, knowledge, inquiry, and sometimes values. The important distinction is that philosophical assumptions can be present even when the researcher does not formally classify the study under a named paradigm.

Explicit Paradigm Identification and Philosophical Awareness Are Not the Same Thing

It is useful to separate two questions:

This distinction prevents an unnecessary leap from "philosophy matters" to "every manuscript requires a paradigm section."

Sometimes philosophical commitments are central enough that readers need them stated explicitly. In other cases, methodological assumptions are communicated adequately through the research question, design, procedures, analytical logic, and limitations.

When Is an Explicit Research Paradigm Particularly Useful?

A paradigm becomes especially useful when readers need it to understand why the research has been designed or interpreted in a particular way.

For example, an interpretive study may rely on assumptions about contextual meaning, researcher-participant interaction, and the situated character of knowledge. A critical realist study may distinguish observable events from underlying mechanisms and structures. A transformative study may explicitly organize inquiry around power, marginalization, participation, and social change.

In such cases, the philosophical position is not decorative. It helps explain the methodology and the claims the researcher intends to make.

Pretorius argues that understanding research paradigms contributes to coherent and philosophically grounded research designs, particularly within humanities and social science research. Paradigms can clarify assumptions concerning ontology, epistemology, and axiology and their methodological implications.

Some Methodologies Carry Strong Philosophical Commitments

Certain methodological traditions are difficult to explain adequately without discussing their philosophical foundations.

If you conduct research explicitly grounded in constructivism, critical realism, critical theory, transformative inquiry, or another philosophically developed tradition, readers may reasonably need to know what those commitments mean for your study.

The same principle applies when your methodology depends on a particular conception of knowledge. If interpretation, co-construction of meaning, causal mechanisms, emancipation, or practical consequences is fundamental to the inquiry, identifying the philosophical framework may substantially improve methodological transparency.

In these circumstances, omitting the paradigm can make the study harder rather than easier to understand.

Other Studies May Not Need a Separate Paradigm Discussion

Now consider a conventional empirical article in a field where researchers routinely report hypotheses, sampling, instruments, statistical models, assumptions, uncertainty, and limitations without providing a separate philosophy-of-science section.

The absence of a heading called "Research Paradigm" does not make the study paradigm-free. It may simply mean that the philosophical assumptions are conventional within that research community and are not treated as information requiring separate exposition in every article.

Space also matters. A doctoral dissertation can devote several pages to methodological foundations. A journal article operating under a strict word limit may communicate its research logic more efficiently through the design and methods.

This is why reporting expectations should not be inferred from one generic methodology template.

What About Quantitative Research?

Quantitative research is often associated with positivism or postpositivism, but researchers should not automatically write "this study uses a positivist paradigm" simply because their dataset contains numbers.

Park, Konge, and Artino describe positivism as a research paradigm with particular ontological, epistemological, axiological, methodological, and rigor assumptions. They associate it strongly with hypothetico-deductive inquiry, operationalization, experimentation, explanation, prediction, replication, and controlled investigation. Importantly, they also note that positivist inquiry does not invariably require quantitative methods.

The reverse inference is equally problematic: using quantitative methods does not automatically establish positivism. Quantitative studies do not have to be positivist.

If your philosophical orientation matters to the interpretation of the design, identify it. If you have no defensible reason for calling your study positivist beyond "I used statistics," adding the label may create more methodological problems than it solves.

What About Qualitative Research?

Qualitative research often makes philosophical assumptions more explicit because many qualitative methodologies have developed in close conversation with interpretivist, constructivist, critical, phenomenological, and other philosophical traditions.

Still, qualitative does not automatically equal interpretivist.

Different qualitative approaches can rest on different assumptions about reality, knowledge, language, experience, and the researcher's relationship to participants. Consequently, an explicit paradigm can be particularly valuable when it clarifies which version of qualitative inquiry is being undertaken.

Researchers should therefore avoid assuming that qualitative studies must be interpretivist or constructivist merely because those associations are common.

Mixed Methods Can Make the Philosophical Question More Visible

Mixed-methods research historically generated substantial debate about whether quantitative and qualitative approaches associated with different paradigms could legitimately be combined.

This is one reason pragmatism became influential in mixed-methods methodology. Yet pragmatism is not mandatory, and contemporary mixed-methods researchers may work from other philosophical positions or explicitly address relationships among perspectives.

If your study combines forms of inquiry that rest on potentially different assumptions, explaining your philosophical rationale can help readers understand how and why integration is possible.

That does not mean every mixed-methods study needs a lengthy philosophical treatise. It means that paradigmatic compatibility may matter when philosophical assumptions affect the logic of integration.

Theses and Dissertations Often Require More Explicit Justification

A thesis or dissertation has an educational purpose in addition to reporting findings. Candidates may be expected to demonstrate that they understand the methodological foundations of their research.

Consequently, graduate programs and supervisors sometimes require researchers to identify and justify a paradigm even when a journal article derived from the same project might discuss philosophy much more briefly.

This is a reporting convention, not evidence that one version of the research possesses a paradigm while the other does not.

If your institution has explicit requirements, follow them. The more specific question of whether a thesis or dissertation needs a philosophy or paradigm section should therefore be answered in relation to both methodology and institutional expectations.

Do Not Choose a Paradigm Just to Fill a Required Box

A common problem occurs when researchers believe they must select one paradigm before they fully understand what the labels mean.

The result can look like this:

"This research uses surveys and statistical analysis. Therefore, it is positivist."

Or:

"This research uses interviews. Therefore, it is interpretivist."

Or:

"This research uses both. Therefore, it is pragmatic."

Those shortcuts confuse methods with philosophical commitments.

Mackenzie and Knipe specifically discuss the confusion that research terminology and simplistic qualitative-quantitative dichotomies can create for early-career researchers. Methods, methodologies, and paradigms should be related thoughtfully rather than assigned through automatic pairings.

A Named Paradigm Should Explain Something

If you identify a paradigm, ask what explanatory work the label performs.

Suppose you state that your study is constructivist. Can you explain what that means for your conception of knowledge? Does it affect how you understand participants' accounts? Does it shape the role of the researcher? Does it influence how findings are interpreted?

If you identify critical realism, can you explain why distinguishing empirical observations from underlying mechanisms matters to your explanatory strategy?

If you identify pragmatism, can you explain how pragmatic assumptions inform the problem, inquiry, consequences, or integration of evidence?

If the answer is simply "my methodology textbook says researchers need a paradigm," the label is probably doing too little.

You Can Explain Assumptions Without Writing a Philosophy Essay

Explicit philosophical justification does not require a miniature history of Western philosophy.

You usually do not need biographies of Auguste Comte, Karl Popper, Thomas Kuhn, John Dewey, William James, or every scholar associated with your chosen tradition. Include intellectual history only when it helps establish assumptions that matter to your research.

The stronger approach is to explain the philosophical commitments that have methodological consequences and connect them directly to your study.

This keeps the emphasis where it belongs: not on proving that you know philosophical vocabulary, but on showing that you understand the logic of your research.

When Naming a Paradigm Adds Value and When It Adds Little

The difference is not that one study has philosophy and the other does not. Both rest on assumptions. The difference is how much readers need those assumptions articulated explicitly to understand and evaluate the logic of each study.

Common Mistakes When Identifying a Research Paradigm

How to Decide Whether You Should Identify a Paradigm

Do not begin by asking which "-ism" you need. Begin by asking whether readers need an explicit philosophical framework to understand why your research works the way it does.

If you do identify one, justify the research paradigm without turning the study into a philosophy essay. Define only what matters, connect those assumptions to methodological decisions, and show the reader what the paradigm helps explain.

The label is the beginning of the justification, not the justification itself.
