Hedging and boosting
Balance hedging and boosting: when to sound cautious and when to sound certain — clearly, undoubtedly, it is evident — and how to calibrate claims to evidence.
In this lesson you will
- Use boosters appropriately
- Balance boosters and hedges in one text
- Calibrate claim strength to evidence
Learn
Boosters increase certainty: clearly, undoubtedly, certainly, it is evident that, demonstrates, conclusively, invariably, of course. Hedges reduce it: may, appears, suggests, to some extent, arguably.
Calibration: strong, replicated evidence → boost (The link between smoking and cancer is firmly established). New or limited evidence → hedge (These preliminary findings suggest…).
Strategic mix: skilled writers boost their main claim and hedge secondary or speculative ones: The data clearly show a decline; the reasons, however, remain less certain.
Over-boosting sounds arrogant or unscientific (This undeniably proves beyond doubt…); over-hedging sounds evasive. Aim for the strength the evidence justifies.
Examples
- The effect is well documented and has been replicated in numerous studies.
- Clearly, demand has fallen; why it has fallen is less clear.
- These preliminary results may indicate a trend.
- Over-boosted (avoid): This undeniably and conclusively proves everything.
