First Find Out Why No Theory Seems to Fit
Do not confuse “I have not found a theory” with “no theory exists”
This distinction is fundamental.
A researcher may search for the exact terminology used in the research question and conclude that the phenomenon has no theoretical foundation. Yet another discipline may study the same underlying process using different language.
A researcher investigating reluctance to use generative AI, for example, might search only for “generative AI resistance theory.” Relevant explanations may instead appear in literatures concerning technology adoption, innovation resistance, trust, risk, professional identity, organizational change, self-efficacy, or institutional practice.
Theory searching therefore requires conceptual searching, not merely keyword matching.
Before declaring a theoretical gap, identify the underlying phenomenon, mechanism, actors, level of analysis, and outcome you are trying to explain. Search those concepts across neighboring literatures and disciplines.
Start with the phenomenon, not the fashionable theory
Researchers sometimes reverse the process. They identify a theory that is widely used in their field and then attempt to translate every research problem into its constructs.
A better starting point is the explanatory need.
What exactly remains unexplained? Is the problem about individual decision-making, learning, identity, social interaction, institutional constraint, organizational change, diffusion, motivation, power, or another process?
Once you can articulate what requires explanation, you can evaluate candidate theories according to whether they address that mechanism or process.
This is central to choosing a theory without forcing one to fit.
There are several different kinds of theoretical mismatch
Saying that a theory “doesn't fit” is too vague to guide a methodological decision. Identify the nature of the mismatch.
| Type of mismatch |
What it might mean |
Possible response |
| Phenomenon mismatch |
The theory explains something substantially different from your research problem. |
Search for another theoretical tradition rather than stretching the theory. |
| Construct mismatch |
The theory addresses the phenomenon but omits a concept central to your question. |
Consider whether extension or a broader conceptual framework is justified. |
| Context mismatch |
The theory may explain the phenomenon, but its assumptions or prior applications do not transfer straightforwardly to your context. |
Apply it cautiously, investigate boundary conditions, or consider modification. |
| Level-of-analysis mismatch |
The theory explains individuals while your problem concerns groups, organizations, institutions, or interactions across levels. |
Seek a theory at the appropriate level or consider complementary perspectives. |
| Purpose mismatch |
The theory answers a different kind of question from the one your study asks. |
Reconsider whether theory is needed in that role at all. |
| Epistemological or methodological mismatch |
The assumptions embedded in the theory conflict with how your study conceptualizes knowledge or explanation. |
Consider another theoretical perspective or explain carefully how theory will be used. |
These problems require different responses. Adding another citation cannot solve a mismatch you have not identified.
An imperfect fit does not automatically make a theory unusable
Theories are abstractions. They rarely reproduce every detail of a particular empirical setting.
A theory may still be useful if its central mechanism or propositions apply to the research problem even though some contextual factors fall outside its scope. In that case, the researcher can acknowledge the boundaries rather than claiming perfect coverage.
This distinction matters because expecting a theory to contain every variable relevant to a phenomenon misunderstands what theory does. A useful theory provides explanatory structure; it does not need to function as an encyclopedia of possible influences.
The question is whether what the theory omits is peripheral to your research question or central to it.
A conceptual framework may be more honest than a poorly fitting theory
Sometimes no single established theory adequately organizes the problem, but the literature still provides strong evidence about relevant concepts and relationships.
In such cases, a researcher-developed conceptual framework may be appropriate.
The framework might synthesize concepts from prior empirical findings, established theories, methodological literature, and other defensible sources without pretending that the resulting structure is itself an established theory.
This option is particularly useful when the research problem is interdisciplinary, emerging, or organized around several concepts that have not previously been unified theoretically.
However, “conceptual framework” should not become a convenient label for unsupported intuition. Every important component and proposed relationship still requires justification.
Understanding the difference between theoretical and conceptual frameworks helps prevent that substitution from becoming merely semantic.
You may need more than one existing theory
No single theory may fit because the phenomenon spans mechanisms or levels that different theories address separately.
An individual-level theory might explain motivation while an organizational theory explains institutional constraints. Neither alone is sufficient because the research question concerns the interaction between individual and institutional conditions.
Using more than one theory may then be defensible.
But multiple theories should not become a rescue strategy for an unfocused study. Each additional perspective should solve an identifiable explanatory problem.
You may be looking at an opportunity to extend an existing theory
Suppose an established theory explains most of the phenomenon well, but your research problem reveals a missing construct, relationship, contextual condition, or sequence.
That does not necessarily mean the theory should be discarded.
The gap may create an opportunity for theory elaboration or extension. Methodological scholarship describes theory elaboration as developing new theoretical insight from preexisting conceptual ideas by specifying, contrasting, or restructuring constructs and relationships in response to empirical observations.
For example, researchers might identify a previously unspecified moderator that explains when a theoretical relationship becomes stronger or weaker. They might distinguish two constructs previously treated as one, specify a missing sequence, or clarify how a relationship changes across contexts.
This is more demanding than simply adding a variable to an existing model. If you intend to modify or extend an existing theory, the proposed change should solve a theoretical problem and preserve clarity about what belongs to the original theory and what you are proposing.
You may genuinely have an undertheorized phenomenon
Some phenomena are insufficiently explained by existing theory. This may occur when technologies, practices, social conditions, or empirical patterns emerge faster than theoretical development, or when established literatures have overlooked particular populations and contexts.
Research on an undertheorized phenomenon can be valuable precisely because existing explanations are incomplete.
Methodological debates about theoretical contribution have warned against assuming that every empirical study must begin with a mature theory. Empirical findings for which existing theories provide inadequate explanations can themselves motivate theoretical development.
But claiming that a phenomenon is undertheorized requires literature work. You need to demonstrate what theories have been considered, what they explain, and where their explanatory limitations lie.
No existing theory may mean theory building is appropriate
If existing explanations genuinely fail, one possible research contribution is to develop theoretical explanation from empirical evidence.
Theory building is not simply drawing a framework after collecting data. It involves developing concepts and specifying meaningful relationships, mechanisms, conditions, or propositions that explain observed phenomena.
Qualitative approaches are often associated with theory development because they can reveal processes and meanings not adequately captured by existing structures. But theory building is not restricted to qualitative research, and not every qualitative study is designed to generate theory.
The intended contribution should therefore be explicit. Are you describing a poorly understood phenomenon? Generating concepts? Developing propositions? Elaborating an existing theory? Constructing a new explanation?
Those are related but not interchangeable objectives.
Novel context alone does not prove that existing theory is inadequate
A common theoretical argument is: “This theory has never been applied to our university, country, profession, technology, or population; therefore, a new framework is needed.”
That conclusion does not necessarily follow.
A new context may provide a useful opportunity to examine the scope or boundary conditions of an existing theory. But geographical or technological novelty alone does not establish theoretical novelty.
You need to explain why the new context should alter the theoretical mechanism, assumptions, constructs, or expected relationships.
If the theory's mechanism should operate similarly, applying it in a new setting may be worthwhile replication or generalization research rather than evidence that the theory does not fit.
A theory that fails may itself become the research opportunity
Sometimes the theoretically interesting question is not “What other theory should I use?” but “Why does this theory fail here?”
If an established theory predicts a relationship that repeatedly does not appear under particular conditions, those conditions may expose its boundaries. If participants behave in ways the theory cannot explain, the discrepancy may reveal an omitted mechanism or assumption.
Rather than hiding such mismatch, researchers can potentially challenge the theory with evidence.
Theoretical progress does not require every study to make the chosen theory look correct.
Watch Out
Do not declare that “no theory exists” merely because familiar theories in your immediate discipline do not fit. Search adjacent literatures, examine alternative terminology, consult foundational and review literature, and distinguish a genuine theoretical gap from a search gap.
Your institution may still require a framework
A thesis template or program may require a theoretical or conceptual framework even when the study concerns an undertheorized phenomenon.
That reporting requirement should be respected, but it does not require pretending that an established theory provides a perfect explanation.
You might instead present the closest relevant theoretical perspectives, explain their limitations, and develop a literature-grounded conceptual framework appropriate to the research question, if your institutional conventions permit that approach.
The broader issue is whether the study actually needs a theoretical or conceptual framework and what form that framework should take.
