Compare the uncalibrated and calibrated claims:

Academic register shifts responsibility from persons to propositions:

  • Anticipatory :

  • Past tense for politeness:

  • Progressive softening:

  • Negative interrogatives inviting agreement:

  • Understatement (litotes):

  • Softened disagreement:

Exercises

Calibrate the claims Rewrite each overclaim as a properly hedged academic sentence.

  1. Remote work makes employees more productive.

  2. The new drug cures the disease.

  3. Video games cause violence.

  4. Our model predicts elections.

De-hedge Each sentence is over-hedged; reduce it to a single, well-chosen hedge.

  1. It might possibly be the case that the sample could perhaps be biased.

  2. It could arguably be suggested that there is maybe a tendency for prices to somewhat rise.

Shift the register Rewrite formally (1–3) or informally (4).

  1. We found out that lots of users put off updating their software.

  2. They looked into the problem but couldn’t figure out what set it off.

  3. The plan fell through because the backers pulled out.

  4. It is regrettable that the anticipated improvement in performance did not materialize. (email to a friendly colleague)
