Hi Owen,

Was your example any more complex, or general? In fact it was heavily
tailored for one simplistic answer only wasn't it? The subject line
informs us it was.

You have in the past used the dictum that one counter-example
devastates a poor hypothesis. What you have here is a two degree
answer that fails for the other 358 degrees, where a one word answer
is insufficient.

Reduce this to chance for haphazard line lengths and a spectrum of
loads, then there's a 50% probability of cooling (absurd of course)
and a 50% probability of heating. Reducing that generality to one
word would give us "maybe."

The subject becomes 99.44% uninforming.
