[EM] Why SFC is better than Condorcet's Criterion
by MIKE OSSIPOFF

I said this before, but it deserves emphasis:

Condorcet's criterion only applies when everyone votes sincerely. SFC
applies if the majority to whom it makes its guarantee vote sincerely. In
other words, it stipulates only that you and a majority that you're in vote
sincerely, while Condorcet's Criterion stipulates that your opponents vote
sincerely too.

It's obvious which is more useful and more believable.

The guarantees made by those criteria are very similar. It could be said
that SFC's guarantee is a little better, since its guarantee that no one you
like less than the CW will win means that if there's a unique winner it will
be either the CW or someone you like better. But in any case, it certainly
isn't less of a guarantee.

Obviously the same comparison can be made between the Smith Criterion and
GSFC.
