Hedging

Wikipedia

'Hedging in arguments means sheltering behind ambiguous meanings so that the sense can be changed later.' (120).

To paraphrase the author's example:

We stated we did not want a full-fledged war in the Middle East; that is still the position, we entered into limited war. (120).

This type of argumentation allows for a 'definitional retreat.' (120).

'Hedging is fallacious because it puts two or more different statements under the guise of one'. (120).

It is a semantic game in parsing the difference between a 'limited war' and a 'full-fledged' war. Is any war 'full-fledged' without nuclear weapons?

Hedging hopes that the reviewer of argumentation, will not know better (120); the information presented becomes useless because it is not presented accurately. (120).

To avoid hedging one could state:

'We are entering into war; we are committed.'

Or:

'We are not entering into war, because the risks are too great.'

Hedging again...

We stated we did not want to colonize Mars, that is still the position, but we have several Mars space missions planned.

Interestingly, Pirie indicates that Nostradamus used hedging to make obscure predictions. (121). The author reasons that observers look for what they want to see as far as what has already occurred and apply what Nostradamus predicted. This does not assist in making accurate predictions. (121).

Hedging uses dishonesty and ambiguity. (121).

Hedging can be used in biblical studies to read into Scripture meanings that can be possibly changed at a later date. There are cultic movements that use prophecy to predict the Apocalypse, more than once.
