[net.politics] seat belts and hidden premises

ark@alice.UucP (Andrew Koenig) (12/24/85)

The current seat belt debate is a good example of a kind of flawed
reasoning that, for want of a better term, I will call a "hidden premise."

Consider what it really means for someone to say

	A, therefore B.

Either that person implicitly believes

	whenever A, then B

or something is missing from the argument.

If A is an explicitly stated premise, and B is the conclusion,
we can look at "whenever A, then B" as a hidden premise.

Now let's apply this to the seat belt argument.  People are saying:

	Seat belts save lives,
		therefore
	people should be required to use seat belts.

The hidden premise here is:

	Whenever an activity saves lives,
	people should be required to perform it.

Now, when the hidden premise is put this baldly, most people would
disagree with it.  Thus, the argument is actually hiding something.

What could it be?  I have my own ideas but would prefer to hear
others' thoughts before I reveal them.

I would reply that

	If drivers and passengers wear seatbelts there will
	be fewer accidents and less personal injury in those
	accidents that do occur.

	This will save me money as a taxpayer and insurance
	purchaser.

	You may also avoid having an accident involving me.

The hidden premise, such as it is, is pure old American self-interest.

Actually, the hidden premise is probably more like:

        Whenever an activity saves many lives at trivial cost,
        people should be required to perform it.

Which has the advantage of being eminently plausible.

Triviality is in the eye of the beholder! In this case the so called 'trivial'
cost is government poking its very long nose into our private lives. The
slow accumulation of such trivial things will lead to less and less freedom
for the individual and more and more power for the government. I agree that
the cost of buckling up is trivial. However, government's REQUIREMENT that
we do so carries a far heavier cost.

... and has the disadvantage of leading us down the garden path
to utter totalitarianism.  The question is: who is to decide what
costs are trivial?  The lawmakers?  They will call anything trivial
if it is in their interest to do so.  That's why we're in the mess
we're in today.
