Key takeaways
- Use passive voice in theses when procedure standardisation matters more than naming the researcher.
- Avoid passive voice in discussions, claims, and methodological justifications where agency clarifies reasoning.
- Your university style guide and supervisor preferences override general voice advice.
Thesis and dissertation writers receive conflicting advice about passive voice. Supervisors in one department insist on impersonal methods sections; journals in another field expect first-person active reporting. Knowing when passive voice is appropriate—and when it weakens your argument—prevents both overcorrection and lazy defaulting to 'was conducted' constructions. This guide maps specific thesis sections and research scenarios to clear voice recommendations with examples you can apply immediately.
Thesis sections where passive voice is common
Methodology chapters in quantitative and experimental research frequently use passive voice for data collection and analysis steps: 'Questionnaires were administered,' 'Samples were analysed using SPSS,' 'Ethical approval was obtained from the university committee.' These constructions foreground procedures that any qualified researcher could replicate.
Thesis sections where active voice works better
- Introduction: 'This dissertation investigates…'
- Literature review synthesis: 'Three themes emerge from prior work…'
- Methodological justification: 'We chose qualitative interviews because…'
- Discussion: 'We argue that the findings suggest…'
- Limitations: 'We acknowledge that sample size restricted…'
- Conclusion: 'This research contributes by…'
Scenario 1: Standard lab or survey procedures
Passive appropriate: 'Blood samples were centrifuged at 3,000 rpm for ten minutes.' The step is standard; naming the technician adds little. Active alternative if transparency matters: 'Research assistants centrifuged blood samples at 3,000 rpm for ten minutes.'
Scenario 2: Original methodological decisions
Active preferred: 'We developed a novel coding framework based on grounded theory principles.' Passive obscures intellectual contribution: 'A novel coding framework was developed.' Examiners want to know you made the decision and why.
Scenario 3: Ethical and administrative steps
Passive common: 'Informed consent was obtained from all participants.' Active also fine: 'We obtained informed consent from all participants.' Either works; consistency within the chapter matters more.
Scenario 4: Reporting results
Mixed usage: 'Mean scores increased from 3.2 to 4.7' (active/descriptive). 'A significant main effect was found for condition, F(1, 98) = 12.4, p < .001' (passive common in statistical reporting). Both appear in published papers; match your field's recent theses.
Scenario 5: Qualitative research
Qualitative theses increasingly use active first person: 'I conducted 15 interviews' or 'We identified three themes.' Passive—'Interviews were conducted'—can feel evasive in interpretive research where researcher positionality matters. Check qualitative methodology conventions in your discipline.
Scenario 6: Multi-author research papers
Active with 'we' clarifies team actions: 'We designed the experiment, collected data, and performed analysis.' Passive without agent can obscure who did what in collaborative work—important for authorship and accountability.
University and examiner expectations
Some Indian university thesis templates still imply impersonal passive construction in methodology. Others follow APA 7's acceptance of first person. Read your handbook, examine three approved theses from your department, and ask your supervisor explicitly. Examiner preferences vary; departmental convention is your safest guide.
Red flags: passive voice to avoid in theses
- 'It is believed that…' without naming who believes.
- 'Mistakes were made' without accountability.
- Chains of passive clauses exceeding one per sentence.
- Passive in abstract and conclusion where direct claims belong.
- Passive to hide weak methodology or missing details.
Balancing voice across a long dissertation
A 100,000-word dissertation will use both voices. Set a convention per chapter type: passive-leaning for standard methods steps, active-leaning for argument and interpretation. Apply consistently so voice shifts signal section purpose rather than random drafting habits.
Editing support for thesis voice
Professional thesis editing reviews voice section by section—retaining appropriate passive in methods while strengthening active clarity in discussion and contribution claims.
