What Would Make You Fail a Dissertation?
Common Reasons for Dissertation Failure
What Would Make You Fail a Dissertation? Poor research design, unclear writing, missed deadlines, weak literature review, ethics violations, and flawed data analysis are common causes of dissertation failure. Most committees reject dissertations that lack rigor, clarity, or scholarly contribution.
A dissertation represents the culmination of years of academic work; therefore, understanding the common pitfalls can help you avoid failure.
Poor Research Design
A solid methodological framework forms the basis of research. Poor research design is the foundation of many failed dissertations.
- Poorly defined research questions create an unstable foundation. Questions that are too broad (“How does social media affect society?”) or too narrow (“How does Instagram usage affect left-handed engineering students at one specific university?”) make research unfocused or ungeneralizable.
- Weak methodology that fails to align with research goals undermines validity. For example, utilizing only quantitative techniques for a subject matter requiring a deep qualitative understanding will produce shallow results.
- Sampling errors are a significant issue. You would fail a dissertation when you use a sample of only 12 participants to make claims about national teaching practices.
- Control issues frequently lead to rejection in different degree programs. A good idea was rejected for major revisions when the committee identified confounding variables not accounted for in the experimental design.
Writing and Structure Issues
Clear, organized writing is essential for conveying complex ideas in a dissertation project. Even with a good idea, poor communication can result in dissertation failure.
- Poor organization makes arguments challenging to follow. A higher ed dissertation quickly fails when the chapters do not connect logically, creating a disjointed reading experience for the committee.
- Unclear prose with jargon, run-on sentences, and vague claims frustrates readers. Even supplemental essays fail when reviewers can’t decipher the author’s dense theoretical framework.
- Grammar and spelling errors suggest carelessness and lack of attention to detail. While minor mistakes are expected, excessive errors indicate a lack of professionalism.
- Improper citation is academically dangerous. Academic institutions take plagiarism seriously. You will likely fail when reviewers discover inconsistent citation formats and missing references, raising questions about academic integrity. A dissertation needs proper citation of related work and authoritative sources.

Missing Deadlines and Requirements
Administrative issues would make you fail even methodologically sound dissertations.
- Late submissions without approved extensions often result in automatic failure at many academic institutions.
- Incorrect formatting that doesn’t meet institutional guidelines signals that a candidate hasn’t read the requirements carefully.
- Incomplete sections or missing required elements cause immediate concerns. A candidate failed when they omitted the required limitations section, suggesting they weren’t critical of their work.
- Ethics violations are severe. A medical dissertation was rejected when the committee discovered that the researcher had not obtained proper informed consent from all participants.
The Critical Role of the Results Chapter
While the entire dissertation must meet high standards, the results chapter deserves special attention as it presents your original contribution to the field.
Why the Results Chapter Matters
- It showcases the outcomes that emerged from your carefully designed research
- It provides the evidence that will support or challenge your hypotheses
- It demonstrates the validity and reliability of your methodology
- It contributes new knowledge to your field through empirical findings
- It creates the foundation for meaningful discussion and conclusions
Seven Critical Mistakes in the Results Chapter
1. Presenting Incomplete or Inaccurate Results
Results that are partial, incorrect, or misrepresented undermine your entire dissertation.
- Omitting contradictory findings: You would fail a dissertation when you exclude survey responses that do not support your research hypothesis.
- Calculation errors: You would fail a finance dissertation when you fail to correct mathematical errors in the statistical analysis that invalidate the conclusions.
- Cherry-picking data: One psychology candidate faced rejection when they selectively reported only positive outcomes from a mixed-methods study.
- Data fabrication: The most serious offence—making up results—leads to dissertation failure, potential expulsion, and permanent academic damage.
2. Failing to Interpret the Results
Raw data without proper explanation leaves readers confused about the significance of your findings.
- Missing analysis of patterns: An economics dissertation presented extensive market data without identifying the meaningful trends within it.
- Disconnection from research questions: You would fail an education dissertation when you fail to explain how your findings answered the original research questions.
- Overloading with numbers: One engineering dissertation included 47 tables of numerical data with minimal explanation, making it impossible for readers to determine what was necessary.
3. Distorting Result Importance
Misrepresenting the significance of your findings damages credibility and scholarly integrity.
- Claiming significance where none exists: You would fail a psychology dissertation when you describe p-values of 0.08 as “approaching significance” without acknowledging they could not meet standard thresholds.
- Using misleading visuals: You would fail a marketing dissertation when you use graphs with truncated axes to make minor differences appear dramatic.
- Ignoring effect sizes: A medical study was returned for revisions because it emphasized statistical significance without addressing the findings’ small clinical impact.
4. Lacking Detail or Context
Results presented without proper context lack meaning and prevent readers from fully understanding your work.
- Missing methodological details: A chemistry dissertation failed to describe specific laboratory conditions that could have affected outcomes.
- Undefined variables: One education study presented learning outcomes without clarifying how these outcomes were measured.
- Insufficient comparison data: A business dissertation showed company performance metrics without industry benchmarks, making it impossible to interpret the results meaningfully.
5. Ignoring Negative or Unexpected Results
Addressing contradictory findings demonstrates scientific integrity and deepens analysis.
- Dismissing contradictions: A psychology dissertation was rejected when the author ignored results that contradicted their theoretical framework without explanation.
- Failing to explore anomalies: One biology dissertation missed an opportunity when unusual results were noted but not investigated.
- Overlooking null findings: A sociology study that found no significant relationships between variables was strengthened when the author thoroughly examined why expected correlations didn’t materialize.
6. Using Inappropriate Statistical Methods
The wrong analysis techniques can invalidate otherwise promising research.
- Mismatched tests: A public health dissertation applied parametric tests to non-normally distributed data, invalidating the findings.
- Ignoring assumptions: One economics study failed to check for multicollinearity in regression analysis, producing unreliable results.
- Overcomplicated analysis: A psychology dissertation used advanced statistical methods unnecessarily, obscuring rather than clarifying the findings.
- Underpowered studies: A medical dissertation was rejected when reviewers determined the sample size was too small to detect the effects the author claimed to find.
7. Mixing Results with Discussion
Blending objective findings with subjective interpretation confuses readers and weakens both sections.
- Premature interpretation: A sociology dissertation included extensive theoretical analysis in the results section, making it difficult to distinguish data from opinion.
- Literature citation in results: One education dissertation incorrectly included comparisons to previous studies within the results chapter rather than in the discussion.
- Making recommendations too early: A business dissertation included implementation suggestions alongside the presentation of findings, violating the expected dissertation structure.
