[EM] CR with AERLO gets rid of the co-operation/defection dilemma

```One more thing: As the subject line says, the co-operation/defection dilemma
that James posed no longer is ia problem when CR with AERLO is used.

To repeat the dilemma, say a majority are roughly equally divided between A
& B, and that that majority much prefer both A & B to the despised C.

Say you're an A-preferrer. Say you responsibly vote for A & B, to make sure
that C is defeated. The B voters could take advantage of your responsible
voting by voting only for B, B wins because B voters are more untrustworthy.

Yes that's a problem in Approval when it happens. No, it isn't a serious
problem, for a number of reasons that I gave when this was discussed. For
one thing, it doesn't make a majority rule violation. For another thing
there are several reasons why it isn't likely or could be avoided. I won't

Anyway, say the method is CR with AERLO. If you're an A-preferrer, draw your
AERLO line beneath A & B, and give maximuim points to A, and give minimum
points to B.

In fact you could do the equivalent same thing with AERLO Condorcet(wv). I'd
previously pointed out that ATLO avoids that problem with Condorcet. But
AERLO avoids it too.

You know, Approval is much less familiar to people than CR is. Everyone's
heard of rating by numbers. Practically no one has heard of Approval. That's
why Approval always comes up against the fallacious "one-person-one-vote"
objection. CR receives no such objection, because it doesn't get mistaken
for illegal Plurality.

Of course, if you're going to propose Approval, offer it as a point system.
The 0,1 point system in which you can give to anyone either 1 point or 0
points. Maybe mention other CR versions first, such as 0-10, 0-100, -10 t0
10, etc.

But, better yet, why not just propose CR instead, because it's what people
are familiar with.

For pure merit, without regard to winnabilitly, if AERLO weren't available,
I'd say that Approval is my favorite CR version. But, for one thing, we have
to consider public winnability instead of just pure merit. Besides, with
AERLO, CR surpasses Approval  in the ways that I've described in these two
postings.
