I called MMPO the best method for current-conditions electorates in this
country, if they want or need ranking.
That might call for a better answer to some of the objections to MMPO.
"Current conditions" refers to dishonest, intentionally disinformational,
agenda-driven mass media, and a public who believe them.
I'm only talking about voting here, & I make no claims about what voters
elsewhere need.
Referring to Kevin's MMPO bad-example, I asked who is wronged in that
example.
Chris gave the best answer. He said that, because the winner should be A or
B (& I agree that would make more sense),...
...then the A voters are wronged, because they have a right for A to win
with 50% probability.
For now, let's assume that's so.
The word "outrage" or "outrageous" was used. How outrageously are they
wronged?
Well, all of the A voters said that C is at least as good as the other
candidate whom they'd like to win with 50% probability.
That doesn't make it very outrageous if C wins.
Yes, C might be a write-in, and might be Donald Duck, or someone widely
disliked, like Hillary Clinton.
But, if write-in are allowed, then the A voters, by not voting a 2nd
choice, are saying that any write-in would be as good as A.
Astonishingly irresponsible voting? Sure.
The method's fault? No.
Another thing:
Surely the badness of a bad-example depends on its plausibility. This
bad-example is highly implausible.
Yes, MMPO can fail to elect a CW.
But, if there is no indifference, a CWv (voted CW) will win.
If the CWv loses because of large-scale indifference, well that just
doesn't sound very complainable.
When MMPO avoids chicken dilemma, it does so by electing A. Some complain
that that violates the Plurality Criterion.
But A is the most favorite candidate who doesn't have majority pairwise
opposition.
C has about twice the pairwise opposition.
As I said, if Plurality says A shouldn't win, then Plurality is mistaken.
Yes, examples can be contrived in which MMPO does terribly by the
positional standard, of the pairwise defeats standard.
But how surprising is it if a method that doesn't use a standard does
pooorly by that standard in an example contrived to achieve that?
It's because MMPO doesn't use those standards that it has its remarkable
combination of properties.
FBC, Weak CD, MAM-like strategy.
I suggest that a voting-system proposal should offer a list of methods.
...ordered by how much you recommend them.
The public &/or the initiative proposal committee could then make their own
choice.
Of course, if you include Plain MMPO in the list, then you must include
pages to tell & answer the objections that have been expressed against it.
That could greatly multiply the length of your proposal.
But, if feasible, I suggest that Plain MMPO be included because of its
properties.
