Modality in Academic and Formal Writing

In academic and formal professional writing, modality is the grammar of careful claims. A scientist who writes X causes Y is making a much stronger statement than one who writes X may contribute to Y. A policy analyst who writes the government must intervene is making a different argument than one who writes the government should consider intervening. The choice of modal verb encodes the epistemic stance (how confident is the writer?) and the deontic stance (what should be done?) — and skilled academic prose uses these consistently to signal both.

At C1, the goal is to write with modal precision — knowing exactly how strong each claim is, hedging when appropriate, asserting when the evidence supports it, and stacking modals when the position is genuinely tentative. This lesson covers epistemic vs deontic modality, the standard academic hedging system, modal stacking in formal prose, and the AmE conventions that distinguish American academic writing from BrE.

Epistemic vs deontic modality

Every modal verb does double duty. The same word means different things in different syntactic frames.

Epistemic modality: the speaker’s confidence about whether a proposition is true.

• The Earth must be older than four billion years. (epistemic: I’m confident based on evidence)
• He may be in the office. (epistemic: I’m uncertain)
• They should have received the package by now. (epistemic: my expectation)

Deontic modality: obligation, permission, recommendation.

• You must submit the form by Friday. (deontic: it’s required)
• You may leave when finished. (deontic: it’s permitted)
• We should revisit the proposal. (deontic: it’s recommended)

In academic writing, both kinds of modality appear constantly. Reading a paper requires sorting them in real time.

The data suggest that interest rates may rise. (epistemic — the writer is hedging a claim) Future studies should address this limitation. (deontic — recommendation to other researchers)

Russian speakers often blur these because Russian collapses several into similar surface forms. English keeps them distinguishable through syntactic context.

The hedging system

Academic writers hedge — they soften claims to leave room for uncertainty. Hedging is not weakness; it’s intellectual honesty. The C1 hedging toolkit:

Modal verbs as hedges

• X may influence Y. (weak epistemic claim)
• X might explain the variance. (weaker)
• X could account for the discrepancy. (tentative)
• X would seem to support this view. (very tentative)

Strength order: will > should > may > might / could > would. The closer to the bottom, the more hedged.

Modal adverbs as hedges

• X possibly influences Y.
• X arguably plays a role.
• X presumably accounts for the effect.
• X conceivably contributes.

These stack with modal verbs: X may possibly influence Y — the strongest form of hedging.

Reporting verbs as stance markers

• The data suggest that X. (cautious)
• The data indicate that X. (somewhat stronger)
• The data demonstrate that X. (strong)
• The data prove that X. (strongest — rare in good academic writing)

A skilled writer matches the reporting verb to the evidence strength. Prove is reserved for mathematical demonstration; suggest is the workhorse of empirical research.

”It is + adjective + that” constructions

• It is possible that X. (hedged)
• It is likely that X. (more confident)
• It is probable that X. (similar to likely)
• It is arguable that X. (formal AmE: usually a case CAN be made for X — a mild endorsement, not “open to dispute”; for “open to dispute” use debatable or contestable)
• It is clear that X. (assertive)
• It is evident that X. (assertive)

These shift the assertion onto an impersonal frame, distancing the writer from direct claim-making.

Modal stacking

In formal academic prose, modals can stack with hedging verbs and adverbs to produce richly hedged claims. Common patterns:

“It may be argued that…”

A double hedge: the modal may + the passive reporting verb be argued. Translates roughly to “one could make this argument; I’m not committing fully.”

• It may be argued that climate policy has been excessively focused on supply-side measures.
• It could be claimed that the methodology has limitations.
• It might be suggested that further research is warranted.

”It would seem that…”

The most hedged epistemic frame in English.

• It would seem that the experimental design accounted for confounding variables.
• It would appear that the policy has had mixed results.

”There appears to be…” / “There seems to be…”

Lexical hedges that displace assertion onto perception verbs.

• There appears to be a correlation between X and Y.
• There seems to be insufficient evidence for this conclusion.

”Studies have shown that X may…”

A cascading hedge — the reporting verb is in the perfect (already established), but the modal hedges the content.

• Studies have shown that exposure may increase risk.
• Researchers have argued that the model may be incomplete.

Modality by section in academic papers

Different parts of a paper use different modal patterns. Recognizing this is part of C1 academic reading.

Introduction

Hedged claims about importance and gap-identification:

• Climate change is widely regarded as one of the defining challenges of the century.
• Existing research has yet to address the question of long-term effects.
• This study aims to contribute to the ongoing debate.

Methods

Often passive, neutral, factual:

• Participants were randomly assigned to three conditions.
• Data were collected over a six-month period.
• The instrument was validated through factor analysis.

Modals are rare here; the writer reports what was done.

Results

Strongly epistemic — direct claims supported by data:

• Results indicated a statistically significant correlation.
• Participants in the treatment group showed marked improvement.
• The model explained 67% of the variance.

Hedging would undercut the data. Be assertive here.

Discussion

Heavy hedging — connecting results to broader claims:

• These findings suggest that X may play a role in Y.
• One possible interpretation is that…
• The data could be read as supporting an alternative view, namely that…

Conclusion / future work

Mostly deontic — recommending further research:

• Future studies should address the limitations identified above.
• Researchers might consider longitudinal designs.
• Further work is needed to establish causation.

Deontic modality in policy and business writing

In policy briefs, business reports, and corporate communication, deontic modality is the language of recommendation. The strength of the modal signals the strength of the recommendation.

Smart business writers tune the modal to the audience and political situation. Recommending too strongly to a senior audience can backfire; recommending too weakly can fail to move them.

Modal-like expressions in academic writing

The expressions from lesson 6 reappear heavily in formal prose:

• The intervention is likely to reduce recidivism.
• Patients are prone to misreporting symptoms in self-administered surveys.
• The model is bound to require refinement as new data emerge.
• The new regulation is due to take effect in January.
• Replication is supposed to be the gold standard, yet it remains rare in practice.

In academic writing, these expressions often substitute for modal verbs to vary syntax and avoid repetition.

Combining hedges: the multi-layer construction

Skilled academic writers combine multiple hedges in a single sentence. The result is a sentence with multiple layers of caution:

• Some evidence may suggest that the intervention could potentially be effective in certain populations. (six hedges in one sentence)
• It would seem that the model may be incomplete, in some respects, to some extent. (four hedges)
• Studies have tentatively argued that the effect may possibly be somewhat attenuated by socioeconomic factors. (four hedges)

This isn’t bad writing; it’s the genre. Over-asserting in academic prose signals naivety and invites peer-review rejection. C1 academic readers expect a baseline of hedging.

That said, excessive hedging is also a fault. The skill is calibrating: assert what your data support; hedge what extends beyond your data.

The vocabulary of stance markers — beyond modals

In academic writing, modality combines with stance vocabulary to position the writer’s relationship to the claim.

Each marker stacks with modals to layer stance: The fund reportedly may have lost over a billion dollars.

Modal voice in scholarly disagreement

Academic disagreement is performed through modal calibration. Strong disagreement uses strong modals; polite disagreement uses hedged modals.

• Strong: This claim cannot be supported by the available evidence.
• Moderate: This claim may require further substantiation.
• Soft: It could be argued that the evidence is more ambiguous than the authors suggest.
• Maximally diplomatic: One might reasonably ask whether the methodology fully addresses the question.

The fourth form — one might reasonably ask whether — is the standard academic move for raising a concern without attacking the author. C1 writers learn to deploy these calibrated modals as part of joining a scholarly conversation.

AmE notes

AmE academic prose hedges less than BrE on average. American journals and reviewers tend to reward direct claims supported by evidence; British academic style tolerates (and sometimes expects) more layered hedging. The data demonstrate that X is more AmE-friendly than It may be argued that the data could be read as suggesting X. Calibrate to the journal.

“Suggest” + bare subjunctive is mandative, not hedging. The committee suggested that the policy be revised — this is the deontic mandative subjunctive (covered in lesson 20 of this module). Don’t confuse with The data suggest that the policy may need revision — which is epistemic hedging.

“Will likely” is AmE-standard. The intervention will likely reduce costs sounds natural to AmE readers; BrE editors often “correct” it to is likely to or will probably. Both are valid; will likely is a clean AmE construction.

“May” vs “might” in AmE academic writing. May is more common in formal scholarly writing than in conversation; might appears in slightly less formal academic contexts. Both are acceptable; consistency within a piece matters more than choice.

AmE deontic should is the workhorse. Researchers should examine this further is the standard AmE recommendation. BrE academic writing more often uses researchers might wish to examine — a softer construction.

Pronunciation notes

In academic prose, modality is primarily a written-register phenomenon. When reading academic prose aloud (lectures, conference papers, podcast academic interviews):

• Modal verbs are typically unstressed, allowing the reader to emphasize the main verb: The data MAY suggest… (no — stress on suggest: The data may SUGGEST…).
• It may be argued that… runs as a single prosodic unit with stress on argued.
• Lecturers often pause after a hedge: Some studies have argued… [pause] …that X may play a role.
• In TED-style academic talks, speakers strip hedges aggressively for impact — X causes Y sounds bolder than X may potentially contribute to Y. The genre rewards assertion.

Common Russian-speaker mistakes

1. Under-hedging — sounding too assertive: Russian academic style allows direct claims that read as over-confident in AmE academic prose. The data prove that X causes Y → The data suggest that X may contribute to Y — match modal strength to evidence.
2. Over-using prove: prove is for mathematical proof. For empirical research, use show, demonstrate, indicate, or suggest. Russian “доказывать” maps to all of these — pick the right one.
3. Confusing epistemic and deontic should: The committee should be aware of this issue is ambiguous in Russian translation. Epistemic should = “I expect they are aware”; deontic should = “they ought to be aware.” English context disambiguates; translation can’t.
4. Calquing Russian impersonal constructions: It is necessary to consider… → We need to consider… / One should consider… AmE academic prose prefers active voice and specific agents more than Russian academic style.
5. Excessive hedging in business / policy contexts: business audiences expect actionable claims. It may possibly be argued that we might consider perhaps revisiting the strategy in some respects — too many hedges for a business memo. Calibrate to genre.
6. Missing modal stacking patterns: failing to recognize it may be argued that as a single hedging construction; parsing may be argued as a passive of argumentation rather than as a stance-marking frame.
7. Misusing can: in academic writing, can often expresses possibility, not ability: Climate models can produce divergent forecasts = “it is possible for them to produce” (not “they have the ability to”). This is generic can — a key feature of scholarly prose.

Summary

• Two modality systems: epistemic (confidence) and deontic (obligation/recommendation). Same words, different jobs.
• Academic hedging toolkit: modal verbs, modal adverbs, reporting verbs, “it is ___ that” frames, modal-like expressions.
• Modal stacking: may be argued that, would seem that, may possibly suggest that — multi-layered caution.
• Match modal strength to evidence strength: over-claim and reviewers reject; over-hedge and readers disengage.
• AmE academic prose hedges less than BrE; AmE rewards direct evidence-supported claims.
• Different paper sections use different modal patterns: methods are factual, results are assertive, discussion is hedged, future work is deontic.
