In academic writing, claims are often couched in cautious or tentative language. This is known as ‘hedging’. Compare these two sentences:
The first sentence indicates a high level of certainty; indeed, the claim, or assertion, is presented as a fact. The second sentence, on the other hand, is more tentative, suggesting that conflict will occur in certain circumstances or under certain conditions, but not necessarily in every case.
As the example above illustrates, the use of hedging enables the writer to make claims that are proportionate to the evidence available at the time of writing. In other words, hedging language helps to make statements as accurate and fair as possible. Since there is a wide range of hedging words and phrases, it is important to choose one that reflects the strength of the supporting evidence. The use of the word ‘probably’ in the sentence below indicates that the evidence is fairly strong. In the second sentence, the more tentative word ‘could’ was selected, indicating that the evidence is weak.
Paying due attention to accuracy and fairness helps to avoid, or at least reduce, criticism of your work. Viewed from this perspective, hedging has a persuasive function.
Hedging is also used to mitigate criticism of other authors’ work, as in the examples below:
A wide range of words and phrases can be used in hedging:
