Epistemic Modesty and the Art of Hedging
This session focuses on calibrating how certain your claims sound. You will learn to deploy modal verbs, tentative verbs, probability adverbs, and author-distancing frames, and to avoid the twin pitfalls of under-hedging and over-hedging.
By the end of this session, you will be able to:
- Explain the concept of epistemic modesty and why scholarly writers avoid expressing absolute certainty.
- Differentiate between unhedged categorical assertions and proportionate, evidence-grounded claims.
- Identify and deploy four key hedging devices: modal verbs, tentative verbs, probability adverbs and quantifiers, and author-distancing frames.
- Apply discipline-appropriate hedging, recognising when to hedge and when to state facts directly.
Understanding Epistemic Modesty and Hedging
Defining epistemic modesty
In academic discourse, writers take care not to appear certain where doubt exists, and they systematically avoid broad over-generalisations where exceptions might occur. This caution is not a weakness — it is a discipline.
What is hedging?
Hedging devices are linguistic mechanisms that mitigate or lessen the epistemological strength — the strength of knowledge — of a statement or claim. They allow a writer to signal exactly how confident the evidence justifies being, rather than defaulting to either full certainty or vague uncertainty.
Why hedge at all?
Softening the tone of assertions enables writers to make claims that are strictly proportionate to the scope and quality of the available evidence. Far from signalling weakness, epistemic hedging demonstrates academic rigour, respects the limits of the data, and leaves room for future inquiry or counter-evidence. A claim that is hedged appropriately is more defensible, not less persuasive.
| Overconfident claim | Epistemically modest claim |
|---|---|
| “This proves the theory is correct.” | “This finding supports the theory.” |
| “All participants improved after training.” | “Most participants showed improvement after training.” |
| “The policy failed because of poor design.” | “The policy’s limited success may be attributable to design factors.” |
Linguistic Mechanics of Hedging
There are four primary categories of hedging device. Strong academic writers move between all four rather than relying on just one.
1. Tentative and attitudinal verbs
Replace absolute verbs with verbs that denote possibility or probability: suggests, appears to, seems, tends to, indicates.
Unhedged: “Drinking alcohol causes breast cancer in women.”
Hedged: “Some studies suggest that drinking alcohol increases the risk of breast cancer.”
2. Low modal verbs
Use may, might, or could to bound possibilities rather than state them as fact.
“This inconsistency may be due to sample limitations.”
“Extreme weather could be a result of climate change.”
3. Probability adverbs and quantifiers
Soften generalisations using adverbs (generally, likely, possibly, conceivably) and bounded quantifiers (most, several, a number of).
“It is likely that these conditions are less common in urban populations.”
4. Author-distancing frames
Use passive or impersonal constructions that distance the author from an unverified proposition: It is widely believed that…, Recent research has suggested that…, There is some evidence to indicate that….
| Hedging device | Examples |
|---|---|
| Tentative verbs | suggests, appears to, seems, tends to, indicates |
| Low modal verbs | may, might, could |
| Probability adverbs / quantifiers | generally, likely, possibly, conceivably, most, several |
| Author-distancing frames | it is widely believed that, recent research has suggested that |
“Sample size limitations explain the inconsistent results.”
“The intervention improves long-term patient outcomes.”
“Students prefer digital feedback to written comments.”
“I think that early intervention improves language outcomes.”
Discipline-Specific Contexts and Placement
Where hedging concentrates
Discussion and conclusion sections of research articles are particularly rich in hedging devices, especially when authors offer explanations for findings or suggest broader implications. Methods and results sections, by contrast, tend to state what was measured directly.
Disciplinary variations
| Field | Typical hedging pattern |
|---|---|
| Social sciences and humanities | Hedging used frequently, reflecting complex, multi-causal phenomena and open-ended interpretation. |
| Natural sciences | Hedging used more sparingly, reserved mainly for interpreting unexpected findings or unproven hypotheses; verified empirical data are stated directly. |
Common Pitfalls: Under-Hedging vs Over-Hedging
Under-hedging
Making sweeping, categorical statements — for example, “The new policy definitely fixes urban housing issues” — leaves the author vulnerable to immediate refutation. A single counterexample can undermine the entire claim.
Over-hedging
Compounding too many hedging devices in a single sentence — for example, “It might possibly seem that the data could perhaps suggest…” — dilutes the argument until it loses all communicative value. One well-chosen hedge is stronger than four stacked together.
| Problem | Example | Better version |
|---|---|---|
| Under-hedged | “The new policy definitely fixes urban housing issues.” | “The new policy appears to improve some urban housing outcomes.” |
| Over-hedged | “It might possibly seem that the data could perhaps suggest a link.” | “The data suggest a possible link.” |
Claim Calibration Workshop
Calibrate each overconfident or absolute claim using appropriate hedging devices. Aim for one well-chosen hedge per sentence rather than stacking several.
The Hedging Audit and Calibration Exercise
Rewrite the discussion-section draft below by introducing modal verbs, tentative verbs, and probability adverbs to align every claim with proper epistemic modesty. Aim for balance — avoid leaving claims unhedged, but also avoid stacking multiple hedges in a single sentence.
