When your marker writes "too assertive" or "you need to qualify your claims", they are asking for more hedging language. Hedging is not the same as uncertainty or weakness — it is the way academic writers signal that their claims are proportional to the evidence supporting them.
What hedging actually is
In everyday language, we often make claims with full confidence: "It's going to rain today" or "She's the best candidate." Academic writing does not work this way, because most academic claims are based on limited, partial, or contested evidence.
Hedging is the linguistic toolkit for expressing calibrated confidence:
"Stress appears to impair working memory performance, particularly under conditions of sustained cognitive load."
This is not the same as saying "I'm not sure." It is saying: the evidence supports this claim, but the relationship is not absolute and applies in specific conditions. Both pieces of information are analytically relevant.
The six types of hedging language
1. Modal verbs
Modal verbs are the most common hedging tool. They express degrees of possibility, probability, or necessity.
| Modal | Certainty level | Example |
|---|---|---|
| will | Very high | "This will reduce..." |
| would | High (conditional) | "This would suggest..." |
| should | High (expected) | "The results should reflect..." |
| may | Moderate | "This may indicate..." |
| might | Moderate-low | "The data might suggest..." |
| could | Low-moderate | "This could be explained by..." |
In academic writing, may, might, and could are the most useful hedging modals. Overuse of will reads as overconfident unless you are describing methodology or stating established facts.
2. Epistemic verbs (verbs of thought/knowledge)
These express the writer's stance toward a claim:
- It seems that...
- It appears that...
- The evidence suggests that...
- The data indicates that...
- This implies that...
- This points to the possibility that...
- One might argue that...
- It can be argued that...
The distance between the writer and the claim matters. "The results prove X" is unhedged. "The results suggest X" is hedged. "One interpretation of the results is X" is more hedged.
3. Adverbs of frequency and degree
These qualify the scope of a claim:
Frequency hedges:
- generally, typically, usually, commonly, often, in most cases, in many contexts
Degree hedges:
- relatively, somewhat, to a certain extent, in part, largely, primarily, predominantly
Limitation hedges:
- particularly, especially, under certain conditions, in specific contexts, for some groups
Example:
"Extended retrieval practice generally improves long-term retention, particularly in declarative knowledge domains."
4. Approximators
When precision is not available or would be misleading, approximators signal that figures are indicative:
- approximately, roughly, around, about, nearly, up to, as many as, in the region of
5. Attribution and distancing
Attributing a claim to its source hedges your own commitment to it:
- According to X (2021)...
- As X (2021) argues...
- X (2021) contends that...
- In X's (2021) account...
- X (2021) has proposed that...
The difference between "X argued" (attribution) and "it is the case that" (assertion) is significant. Attribution signals that the claim belongs to a specific scholar whose argument may or may not persuade you.
6. Conditional structures
If-then structures limit the scope of a claim:
- If X holds, then Y follows.
- Provided that the sample is representative, these findings suggest...
- Assuming the methodology is valid...
- Under the conditions described, this approach may be effective.

When NOT to hedge
Hedging poorly-supported claims is appropriate. Hedging well-established facts is a stylistic error that weakens your writing:
| Unnecessary hedging | Better |
|---|---|
| "It could be argued that the Earth appears to orbit the Sun." | "The Earth orbits the Sun." |
| "Reading may possibly involve the eyes." | "Reading involves visual processing." |
| "The French Revolution might have occurred around 1789." | "The French Revolution began in 1789." |
Hedge claims where the evidence is partial, contested, or specific to a context. Do not hedge facts that are not contested in the relevant literature.
Hedging in different sections of an essay
Introduction: Light hedging — the thesis is stated as an arguable claim, which is itself a form of hedging (it is an argument, not a fact). Use "this essay argues that" rather than "this essay proves that."
Body paragraphs: Moderate hedging on evidential claims. Use modal verbs and epistemic verbs when introducing evidence and explanations.
Conclusion: Slightly lighter hedging than the body — the synthesis is drawing on all the evidence already presented, so more confident restatement is appropriate. But do not drop all hedges; synthesis is still argument, not fact.
