“I’ve read the theory” and “I’ve chosen my theoretical framework” sound like the same stage of a dissertation. They’re not — and the gap between them is one of the most common reasons markers send a chapter back with some version of: “why this theory, and not another?”
Where This Goes Wrong
It’s entirely possible to have read Role Theory, Institutional Theory, and two or three other well-established frameworks relevant to your topic, and still not have answered the question a theoretical framework chapter actually requires: why is this particular lens the right one for this particular research question, in this particular context — and not one of the other plausible candidates sitting on your desk?
Reading widely gets you a shortlist. On its own, it doesn’t get you a justified choice. And a shortlist, presented as if it were a decision, is exactly what triggers the “why this one” comment from examiners — because from where they’re sitting, no decision has actually been shown, only a summary of options.
What a Justified Choice Actually Requires
A defensible theoretical framework justification does three specific things that a literature summary doesn’t:
First, it names what your chosen theory illuminates about your specific research question that an adjacent theory wouldn’t — not what the theory says in general, but what it does for your particular study.
Second, it’s honest about what your chosen theory is known to miss or handle poorly, and states why that limitation doesn’t undermine your particular use of it. Every theory has known critiques; ignoring them looks like you haven’t engaged with the debate, while naming and addressing them looks like you’ve made a considered choice.
Third, it explicitly rules out at least one serious alternative, briefly, in the same terms — not as an afterthought, but as part of the argument. “I considered Institutional Theory, which is strong on explaining organisational-level conformity, but my research question is about individual role conflict, which Role Theory addresses more directly” is a justification. A paragraph that describes Role Theory alone, however well-written, is not.
A Worked Example
Take a study on what drives purchase intention toward fast fashion among consumers who describe themselves as sustainability-conscious. The Theory of Planned Behaviour and Social Identity Theory are both genuinely plausible candidates — the gap between stated environmental attitudes and actual buying behaviour could be explained through the lens of perceived behavioural control and subjective norms, or through the lens of group belonging and identity-driven consumption overriding personal attitudes.
The justification isn’t “the Theory of Planned Behaviour is widely used in consumer research” — that’s true of both candidates and settles nothing. It’s: “This study is concerned with why stated sustainability attitudes fail to predict actual purchasing, which is precisely the attitude-behaviour gap the Theory of Planned Behaviour’s constructs of subjective norms and perceived control are built to explain. Social Identity Theory would better explain why consumers align their purchases with a peer group’s consumption patterns regardless of personal attitude, which is a related but distinct question from the one this study asks.” That’s a choice, argued and defensible, not a summary.
Why Markers Look For This Specifically
Examiners aren’t testing whether you’ve read theory — most candidates at MBA and DBA level clearly have. They’re testing whether you can reason your way to a specific, defensible decision under alternatives, which is a core research skill quite separate from reading comprehension. A theory section that only describes is demonstrating the wrong skill.
FAQ
How many alternative theories should I discuss? Usually one or two genuine, serious alternatives are enough. Listing five just to seem thorough tends to dilute the argument rather than strengthen it.
Can I use more than one theoretical framework? Yes, in some designs — but the same justification logic applies: you need to explain specifically what each theory contributes and how they combine, not simply present both.
What if I’m still not sure which theory actually fits? That’s a specific, answerable question, distinct from needing to read more theory generally — and it’s exactly what my Theory Matcher tool was built to help with.
