Hedging and modality in EAP

academic writing

To get an idea of the importance of this area, compare:

  1. It is clear that Guru is right when he states ... and we must act on his proposal by ...
  2. It is probably arguable that Guru may well be right when he states ... and it may be advisable to act on his proposal by ...

Sentence 1. invites the reader try to imagine all the times when Guru is wrong and also to reject the obligation to do anything at all.
Sentence 2., on the other hand, is appropriately hedged with modality, expressing doubt rather than certainty and possibility rather than obligation.  It sounds reasoned and tentative rather than trenchant and intransigent.

Getting this right is not something that comes easily to writers operating in their first languages and in an additional language is even more difficult so the area needs attention.  The failure to modulate assertion appropriately is common especially for inexperienced or non-native writers.

How to hedge

The term hedging is somewhat disparaging, implying wishy-washiness and the inability to be decisive.  Consider this example from the once-popular British TV series, Yes Minister.  It is the response of a civil servant to the Minister's simple question
... are you going to support my view that the Civil Service is over manned and feather-bedded, or not?  Yes or no?  Straight answer.

yes minister

Well Minister, if you asked me for a straight answer, then I shall say that, as far as we can see, looking at it by and large, and taking one time with another, in terms of averages of departments, then, in the final analysis, it is probably true to say that, at the end of the day, in general terms, you would probably find that, not to put too fine a point on it, there probably wasn't very much in it one way or the other, as far as one can see, at this stage.
(Yes, Minister, Series 1 (1980), Episode Five: The Writing on the Wall)

This is, of course, an extreme example, designed for comic effect but it is also clear that a response such as
No, Minister.
would not have been appropriate, given the fuzziness of the data and the speaker's wish to be uncommitted.

Hedging of that sort is not appropriate but hedging in academic writing is very frequent and very frequently not satisfactorily achieved either by inexperienced writers in their first language or those struggling to write in academic style in a second language.

In this guide, the focus is on hedging in the statement of a proposition, but the choice of reporting verb, in the case of comment on another's work is also important.  For more on how the choice of reporting verb affects the communicated attitude of the writer, see the guide to reporting verbs in EAP.

Ways to hedge

There are a number of ways to classify hedging in academic writing (and arrange a teaching programme).  We'll look at two here, one focused on function and one on form, which seem the most useful for our purposes.  For more data on vague language, try the excellent book by Channell (1994).

function

Focus on function

The following is drawn from Jordan (1997) who follows Salager-Meyer (1994).

  1. Shields:
    shield
    These terms express degrees of certainty or possibility and include a range of pure and marginal modal verbs as well as adverbials used to soften the a proposition, i.e., to shield the writer from accusation of too much assertion.  Examples will be enough here but see below under form for more analysis.
    1. Pure modal auxiliary verbs:
          The discrepancy could be the result of ...
          It might be argued that ...
          It does not have to be the case that ...
          It may be argued that ...
          Some would argue that ...
    2. Marginal modal verbs:
          It seems to be the case that ...
          This tends to be the result of ...
          It is likely to be caused by ...
    3. Adverbials:
          This results, quite possibly, in ...
          It seems arguably possible that ...
          Conceivably, ...
          Presumably, ...
  2. Downtoning, approximating and (less frequently) intensifying:
    softeners
    These terms are usually adverbials, often just adverbs.  They generally modify adjectives or other adverbs.  For example:
    1. Downtoners:
          The is slightly different from arguing that ...
          This is marginally different from ...
          This results, to some extent at least, show ...
    2. Approximators:
          This is approximately the same number of ...
          Roughly, the data can be divided into three sections
    3. Intensifiers:
          It is particularly noteworthy that ...
          There are impressively close parallels between ...
  3. Expressions which imply the author's personal viewpoint.
    viewpoint
    For example:
        As far as I am able to discover ...
        We have no direct knowledge of ...
        We are unaware of any contrary findings in the literature.
    A now famous example in the literature is this one concerning the discovery of the structure of DNA:
        It has not escaped our notice that the specific pairing we have postulated immediately suggests a possible copying mechanism for the genetic material.
    (Watson and Crick, 1953, p738)
    They could of course have said, It is obvious that ... and we have won a Nobel Prize but that is not the way it's done.
  4. Compounding the hedges.  It is possible to heighten the hedging effect by combining any of the above.  For example:
        It may, quite arguably, be the case that ...
        It seems, as far as we can discover, to be the result of ...
form

Focus on form

An alternative way to classify how we hedge is to look at which forms we use rather than the (many) functions they perform.

  1. Modal verbs:
    As we saw above, of the pure modal verbs, could, may, might, would are common hedges and, in the negative only, don't/doesn't have to is usable.  The three marginal modal verbs exemplified above also play a role.  The modal would is often used to distance the writer.  Compare, for example:
        We argue that ... vs. We would argue that ...
    Modal verbs not used in this way, or in academic writing generally, include should, must, ought to and, in the negative couldn't and can't (have).  These make the writer seem overly assertive and are avoided.  For example:
        This must / can't / couldn't be be the result of ...
        We should focus on ...
        It ought to be clear that ...
  2. Lexical verbs:
    These are often copular verbs standing in place of the too-assertive, be.  Compare, e.g.:
        This is the result of ... vs. This appears to be the result of ...
        The outcome is that ... vs. The outcome appears to be that ...

    Other verbal processes are also common.  For example:
        This suggests (i.e., I suggest)
        This leads to the conclusion ...
    (i.e., I conclude)
    In general, the present-simple use of the verb be sounds overly assertive in many cases.
  3. Modal adverbials.  See above for other examples.  Here are some more:
        It is apparently the case that ...
        Seemingly, the respondents have taken the view that ...
        Ostensibly, this is a reason for concern
        Outwardly, the materials are ...
    etc.
  4. Modal adjectives, often used predicatively after a complex nominalisation.  For example:
        A probable outcome is ....
        A new and more complex model of the phenomena is possible
        One quite likely outcome is ...
        More serious and longer-lasting consequences are imaginable
        It is conceivable that ...
        The results so far are promising

    etc.
  5. Modal nouns formed from these adjectives are an alternative.  For example:
        One possibility is that ...
        A reasonable assumption might be that ...
        Our hypothesis is that ...
        A postulation we can put forward is that ...
        One proposition is ...
  6. Prepositional phrases, acting often as adverbials, can also be used to soften the assertive nature of a proposition.  For example:
        This is, as far as we can see, ...
        By and large, the process can be described as ...
        If one looks in terms of averages ...
        At this stage, it is difficult to predict ...
        In general terms, ...

Teaching and learning issues in EAP

As with much else in English for Academic Purposes, the situation is complicated and the range of hedging terms is too great to present easily.  A piecemeal approach over a series of lessons using elements of the analysis above is advisable.
You can take a function-to-form approach or a form-to-function approach but:

  1. A function-to-form approach works best if you are focused on getting learners to produce suitably hedged expressions because they know (or should) what exactly it is that they want to express and need you to provide appropriate realisations of the functions.
  2. A form-to-function approach works best if you are focused on enabling learners to unpack the hidden messages in what they read because the forms are easy enough to spot (if you have primed their noticing) and then they can focus on what the author's intention is.
  1. cars obviously can sometimes create what some see as harmful pollution
  2. it is often asserted that cars create harmful pollution
  3. it is often asserted that cars may create harmful pollution
  4. it is often asserted that cars create harmful pollution in most circumstances
  5. it is often asserted that cars create harmful pollution in some circumstances
  6. cars are polluting monsters which should be banned forthwith
