What is a research paradigm?

A research paradigm is the basic set of beliefs — ontology, epistemology and methodology — that guides a researcher’s inquiry, shaping what they study and how they study it.

The step most authors miss

Doing CRediT right? Don’t stop at the statement.

A CRediT statement credits you inside one paper. The recognition CRediT was built for happens when those roles are tied to you, persistently. Sign in with your ORCID — free — and claim your CRediT contributions on casrai.org, the home of the standard. They become a verified, portable part of your identity, not a line that disappears into one PDF.

Free: claim your contributions, then export a journal-ready CRediT statement, schema.org structured data, JATS XML, CSV or BibTeX — and preview your public profile. A membership publishes that profile publicly and verifies the journals you serve.

What a paradigm includes

A research paradigm bundles three linked assumptions. Ontology states the nature of reality (one objective world, or many constructed ones). Epistemology states how that reality can be known and what counts as valid evidence. Methodology states the logic of inquiry that follows — the broad strategy linking questions to methods. Some accounts add axiology, the role of values. Because these elements are interdependent, a paradigm is more than a method label: it is a coherent worldview that justifies why a study is designed the way it is.

Common paradigms

Four paradigms recur in methods textbooks. Positivism assumes an objective reality knowable through measurement, favouring quantitative, hypothesis-testing designs. Interpretivism or constructivism assumes socially constructed realities best understood through participants’ meanings, favouring qualitative work. Pragmatism rejects the either/or, choosing methods by what best answers the research question and underpinning much mixed-methods research. Critical or transformative paradigms foreground power, inequality and change. Each carries its own standards for judging quality and rigour.

Why declare your paradigm

Naming a paradigm early gives a study a defensible spine. It signals to examiners and reviewers that your ontology, epistemology and methods cohere, and it tells readers which criteria — validity and reliability, or credibility and transferability — should be used to judge your work. A clear paradigm also prevents the common error of borrowing a method without the assumptions that make it meaningful, which weakens both the analysis and the trustworthiness of the conclusions.

Key facts

At a glance

Definition: a basic belief set guiding inquiry (ontology + epistemology + methodology)
Origin: popularised by Thomas Kuhn; adapted for social-science methods
Components: ontology, epistemology, methodology (sometimes axiology)
Examples: positivism, interpretivism/constructivism, pragmatism, critical
Determines: research questions, accepted evidence and chosen methods
Quality test: alignment of beliefs, design and analysis across the study

Common misconceptions

What people often get wrong

Often heard: A research paradigm is just another name for a research method.

Actually: A paradigm is the belief system — ontology, epistemology and methodology — that justifies a method. The method is a tool chosen within the paradigm, not the paradigm itself.

Often heard: Quantitative research belongs to one paradigm and qualitative research to another, with no overlap.

Actually: While positivism leans quantitative and interpretivism qualitative, pragmatism deliberately combines both, and paradigm choice is driven by assumptions and questions, not method type alone.

Often heard: Researchers can mix paradigms freely without it affecting rigour.

Actually: Paradigms carry their own quality criteria. Combining assumptions carelessly undermines coherence; mixed-methods work succeeds by adopting a guiding paradigm such as pragmatism that integrates them deliberately.
