Voice + cohesion by the numbers
- 21% of total content in published research articles consists of hedging language (Hyland, Metadiscourse, 2019).
- 5 to 8 transitions per page is the typical density in distinction-grade dissertations (Bennett, 2024).
- 30 to 40% mark-improvement potential between weakest and strongest 10% of UK undergraduate writing on examiner clarity scales (UKCGE, 2024).
- 3 to 5 cohesion devices per paragraph in published academic prose (lexical repetition, pronouns, conjunctions, transitions).
- 87% of UK examiners report that “argument flow” is more important than “factual accuracy” in distinguishing 70+ from 60–69 work.
Hedging — calibrating claim strength to evidence
Hedging means using language that matches the certainty of your evidence. Over-claiming damages credibility; under-claiming wastes findings.
| Strength | Verbs | Modal verbs | Adverbs |
|---|---|---|---|
| Strong | demonstrates, establishes, confirms | will, must | clearly, conclusively |
| Moderate | indicates, supports, suggests strongly | should, would | consistently, generally |
| Tentative | suggests, implies, may indicate | may, might, could | possibly, perhaps, tentatively |
| Speculative | might be, could imply | might, could | it is possible that… |
Worked examples — same finding, different hedge levels:
- Strong: “The data establish that nurse-led clinics produce better blood-pressure outcomes.”
- Moderate: “The data indicate that nurse-led clinics likely produce better outcomes.”
- Tentative: “The data suggest nurse-led clinics may produce better outcomes.”
- Speculative: “The data could imply nurse-led clinics produce better outcomes.”
Match the strength to your evidence: a single small-sample qualitative study warrants tentative; a multi-site RCT warrants moderate-to-strong.
Transition phrases by function
| Function | Phrases |

| Contrasting | however, by contrast, nevertheless, conversely, on the other hand |
| Causing | therefore, consequently, as a result, thus, hence |
| Sequencing | first, second, in turn, subsequently, finally |
| Exemplifying | for instance, for example, to illustrate, specifically |
| Concluding | in summary, overall, to conclude, in short |
| Conceding | although, while, despite, granted that |

Cohesion — making sentences and paragraphs link
Cohesion is what makes one paragraph follow naturally from the previous. Six devices:
- Lexical repetition — repeat key terms (“authenticity”) rather than over-using pronouns.
- Synonym chains — vary repeated terms with synonyms (“authenticity → genuineness → credibility”).
- Pronouns + reference — “this finding”, “these results”, “that argument”.
- Substitution — “those” referring to a previously listed set.
- Conjunctions — and, but, or, so at sentence level.
- Transitions — at paragraph level (table above).
Paragraph-level worked example
Weak (no cohesion): “Bloom et al. (2015) found a 13% productivity gain in remote workers. Yang et al. (2022) found no productivity gain. Choudhury et al. (2021) found a 4.4% gain. Microsoft (2022) found mixed results. The literature shows conflicting evidence.”
Strong (cohesive): “Field experiments with objective output measures consistently report productivity gains: Bloom et al. (2015) found 13% in a Ctrip RCT, while Choudhury et al. (2021) found 4.4% at the US Patent Office. By contrast, large observational studies of pandemic-era remote-work transitions reach more cautious conclusions. For instance, Yang et al. (2022) found no productivity decline in 61,182 Microsoft employees but documented significant cross-team collaboration loss. Taken together, these findings suggest that whether remote work is productive depends on how productivity itself is measured — a methodological tension this dissertation seeks to resolve.”
Same five sources, same finding — but the second paragraph clusters by methodology, uses transitions, and ends with a forward bridge.
Register — formality without stiffness
| Avoid (informal) | Use (academic) |
|---|---|
| a lot of, lots of | numerous, considerable, extensive |
| get | obtain, acquire, receive |
| show | demonstrate, indicate, illustrate |
| look at | examine, investigate, analyse |
| find out | determine, ascertain |
| good / bad | positive/negative; favourable/unfavourable |
| things | factors, elements, components |
| also (overuse) | furthermore, in addition, equally |
