To ‘hedge’:
· To use an intentionally noncommittal or ambiguous statement
· To use evasive or deliberately vague language
· To avoid fulfilling or answering a question completely
· To be confidently uncertain
· To use verbal and adverbial expressions such as can, perhaps, may, suggest, which deal with degrees of probability
In order to distinguish between facts and claims, writers often use tentative language such as it seems likely that... or arguably.... This technique is called hedging or vague language. Hedging is crucial in academic discourse, and hedge words account for approximately 1 word in every 100 in scientific articles.
Example: “Our results seem to suggest that in less industrialised countries the extensive use of land to grow exportation products tends to impoverish these countries' populations even more”.
It is often believed that academic writing, particularly scientific writing, is factual. However an important feature of academic writing is the concept of cautious language, or "hedging". It is necessary to make decisions about your stance on a particular subject, or the strength of the claims you are making. The appropriate use of hedging strategies for academic argumentation is a significant resource for student writers and plays an important part in demonstrating competence in a specialist register.
Four reasons to hedge
1- By hedging, authors tone down their statements in order to reduce the risk of opposition. This position associates hedges with scientific imprecision and defines them as linguistic cues of bias which avoid personal accountability for statements.
2- Writers want their readers to know that they do not claim to have the final word on the subject.
Expressing a lack of certainty does not necessarily show confusion or vagueness. One could consider hedges as ways of being more precise in reporting results. Hedging may present the true state of the writers' understanding and may be used to negotiate an accurate representation of the state of the knowledge under discussion. In fact, academic writers may well wish to reduce the strength of claims simply because stronger statements would not be justified by the data or evidence presented.
3- Hedges may be understood as positive or negative politeness strategies in which the writer tries to appear humble rather than arrogant or all-knowing. Hedging is a rational interpersonal strategy which supports the writer's position, builds writer-reader (speaker/listener) relationships and guarantees a certain level of acceptability in a community. Once a claim becomes widely accepted, it is then possible to present it without a hedge.
4- A certain degree of hedging has become conventionalized; hedging now functions to conform to an established writing style in English.
