In rank methods, we've been calling that offensive truncation.

In Approval, I don't regard it as an offensive strategy at all. In
Approval, the middle CWs doesn't need support from both sides, as s/he does
in general pairwise-count methods.

The larger wing isn't the one that needs the CWs, if you're after the
best particular candidate you can get. But you're talking about a strategy
problem that shouldn't concern voters in Approval.

Mike,

Given my selection of quotes above, I find your negativity on
Smith//Approval  (very similar to Max Covered Approval) a bit inconsistent.

A couple of somewhat relevant questions:

(1)How often is a sincere Condorcet winner who is supported by the
smallest of three factions of voters the Approval winner?

(2) How often is the Approval winner not in the Smith set?

And so what is wrong with Condorcet//Approval?

Jameson:-In Condorcet systems, the CW wins under honesty by definition.
But under SHOS, any CD-compliant method gets the wrong answer.

Mike: No. In wv, a CWs isn't vulnerable to truncation. S/he still wins.
...the right answer in such a method.

But Winning Votes isn't a "CD-compliant method" .

Jameson wrote:

Support Accept Reject Abstain voting works as follows:

- Voters can support, accept, reject, or abstain on each candidate.
Default is abstain.
- Call a candidate "acceptable" if they are rejected by 50% or less
and supported or accepted by over 25%. If any candidates are acceptable,
eliminate all who aren't.
- Give remaining candidates 2 points for each "support", 1 point for
each "accept", and half a point for each "abstain". Highest points wins.

I still hate default being anything other than bottom/"reject", and the
"25%" figure looks arbitrary.

With the default rule as it is, it looks like the method fails
Mono-add-Plump.

Say the winner X has a lower point score than some other candidate Y that
is barely rejected by over 50%. Then adding some ballots that do nothing
but "support" X could raise the 50% threshold enough so that now Y is no
longer eliminated and wins.

So it refers to a special case of the problem of the defensive strategy
needed to protect the CWs's win.

Certainly, in IRV, Benham, & Woodall, the main problem is when a middle
Cws has the smallest faction.

And, in other pairwise-count methods, when I test for truncation or
burial vulnerability, I use such an example, because it seems more
favorable to finding vulnerability.

But a CWs can lose without being smallest, and I don't make a distinction
about that except that it's part of the problem-examples in IRV, Benham,
and Woodall.

Sure. I was saying that with wv strategy, truncation from one side can't
take the win from the CWs. ...& that the CWs's voters can deter burial by
mere plumping.

No need for the non-offensive wing to vote any less than sincerely in
methods with wv strategy.

As you know, that isn't so with other Condorcet versions or general
pairwise-count methods.

Well, it isn't so much the size of the wing factions. It's more a matter
of which wing candidate is preferred by the CWs's voters.

That's why I've been saying that IRV is fine for you if you're
majority-favored.

If the CWs's voters transfer the other way, then you aren't in a
mutual-majority, and then, for you, IRV is then no better than Plurality.

Many of us have been explaining that to Rob Richie for the past 30 years
or so.

-In systems like approval and score, the CW may or may not win under

"honesty" (however defined). Arguably, if they do not, they should not.

(endquote)

Correct. When sincerely-voted Approval chooses differently from
Condorcet, it's choosing socially better.

Sure, not choosing the CWs got IRV repealed in Burlington.

Not electing the CWs results in a majority who'd prefer a different
result.

But I think IRV was repealed for more than that:

Approval let's people protect the CWs, without favorite-burial,  if that
were what they want to do.  ...and I suggest that it isn't, because
electing from your top-set is usually more important than electing the best
particular individual candidate you can.

CWs protection is more for rank methods, which are about choosing among
your top-set, to elect the best particular candidate you can.

(But see my earlier post yesterday, about that.)

If you have a top-set, then, by definition, electing from it is the
important thing.

Approve (only) your top-set.

(More about that in my post yesterday)

But, if it turned out to be really important to avoid having a majority
who'd prefer a different result, then that  could be a reason for voters in
Approval to slightly modify their voting to avoid approving past the
expected CWs (CWse). ...though that would lower your Pt.

When approving your top-set, you'd just stop short of approving past the
CWse.

Yesterday, too, I spoke of the possibility of your wing-faction having a
social agreement to that effect.

What you're saying doesn't contract what I've been saying.

Both, if people are trying for the best candidate they can get. Then
obviously the smaller wing should support the CWs, and the CWs's voters
should plump.

But I don't suggest that goal for Approval, for the reasons stated above,
& in earlier posts.

-In Condorcet systems, the CW wins under honesty by definition. But

under SHOS, any CD-compliant method gets the wrong answer.

No. In wv, a CWs isn't vulnerable to truncation. S/he still wins. ...the
right answer in such a method.

With burial, a potentially  successful buial can succeed or fail,
depending on whether the CWs's voters plump. Either way, the CWs doesn't
win.

backfire is a good thing if it discourages the strategy, but a bad thing if
it actually occurs.

Yes, that's what makes Condorcet at least a bit questionable.
...especially with the possibility of the perpetual burial fiasco.

But it can probably be argued that, with rank methods' goal of getting
the best individual candidate you can get, wv strategy improves on Bucklin,
because, even if people misjudge who the CWs is, and so hir voters don't
plump, the mere threat of plumping could be enough to deter burial, because
the would-be buriers don't have better information than the defenders have.

-In most basic Bucklin systems, the CW faction must defensively plump

to counteract SHOS.

Yes, in Bucklin, if you aren't majority-favored, and if you rank
sincerely, and if the CWs's voters don't plump, then that can result in the
election of someone in your bottom-set.

(You wrote):

-In a system like SARA, in most cases, even if the CW does not

defensively plump, the weaker wing can give enough support to the CW to
protect them from SHOS, without having to rate them equal-top. (If the CW
is only barely a CW, the weak wing may have to rate equal-top for a
successful defense in this case. However, I think that very
tightly-balanced situations like this are not a large concern.)

(endquote)

That makes me sit up & take notice, because such an improvement on
Bucklin strategy, while keeping FBC, would be major, & could outweigh the
lack of CD enough to compete with the best methods.

Jameson--

You said that SARA does particularly well by VSE.

But VSE is: (winner's SU)/(average SU among candidates)

...where SU is social utility.

...which is some constant minus BR.

But I've just told why BR is no good as a measure of the rightness or
goodness of an outcome.

Take a dollar from a homeless man and give it to a billionaire? That's a
negative change, because changes in greater disutilities are more important

I've tweaked the wording for SARA again. The only substantive changes in
outcome from this new wording is the change from "50 points or more" to
"more than 50 points".

Here's the latest wording, in 3 steps:

Support Accept Reject Abstain (SARA) works as follows:

1. *Voters can support, accept, reject, or abstain on each candidate.
Default is abstain. Candidates get 2 points for each percent of "support"
and 1 point for each percent of "accept", for a total of 0-200 points.*
   - *"Support" the best candidates (perhaps a quarter of them),
   "reject" the worst (perhaps half of them). "Accept" and "abstain" are for
   the ones in the high middle range. For those, "accept" if you want to help
   them beat somebody worse, and "abstain" if you could live with them but are
   hoping for somebody better.*
2. *Eliminate any candidates rejected by over 50%, unless that leaves
no candidates with over 50 points.*
   - *If possible, the winner shouldn't be somebody opposed by a
   majority. But this shouldn't end up defaulting to a candidate who couldn't
   at least get accepted by over 1/2 or supported by over 1/4 (as in, a
   majority subfaction of a divided majority, such as Nashville voters in the
   example below).*
3. *Highest points wins. In case of a tie, fewest rejections wins.*
   - *This finds the candidate with the widest and deepest support.*

Support Accept Reject Abstain voting works as follows:

- Voters can support, accept, reject, or abstain on each candidate.
Default is abstain.
- Call a candidate "acceptable" if they are rejected by 50% or less
and supported or accepted by over 25%. If any candidates are acceptable,
eliminate all who aren't.
- Give remaining candidates 2 points for each "support", 1 point for
each "accept", and half a point for each "abstain". Highest points wins.

This moves a bit away from the Bucklin roots of MAS, but it further
reduces the instability of cooperation in a CD scenario.

     Mike,

     Given my selection of quotes above, I find your negativity on
     Smith//Approval  (very similar to Max Covered Approval) a bit
     inconsistent.

     A couple of somewhat relevant questions:

     (1)How often is a sincere Condorcet winner who is supported by
     the smallest of three factions of voters the Approval winner?

     (2) How often is the Approval winner not in the Smith set?

     And so what is wrong with Condorcet//Approval?
     Jameson:-In Condorcet systems, the CW wins under honesty by
     definition. But under SHOS, any CD-compliant method gets the
     wrong answer.

     Mike: No. In wv, a CWs isn't vulnerable to truncation. S/he
     still wins. ...the right answer in such a method.
      But Winning Votes isn't a "CD-compliant method" .

     I still hate default being anything other than

     With the default rule as it is, it looks like the method fails

     Say the winner X has a lower point score than some other
     candidate Y that is barely rejected by over 50%. Then adding
     some ballots that do nothing

     So it refers to a special case of the problem of the
     defensive strategy needed to protect the CWs's win.

     Certainly, in IRV, Benham, & Woodall, the main problem is
     when a middle Cws has the smallest faction.

     And, in other pairwise-count methods, when I test for
     truncation or burial vulnerability, I use such an example,
     because it seems more favorable to finding vulnerability.

     But a CWs can lose without being smallest, and I don't make a
     distinction about that except that it's part of the
     problem-examples in IRV, Benham, and Woodall.

     Sure. I was saying that with wv strategy, truncation from one

     No need for the non-offensive wing to vote any less than

     Well, it isn't so much the size of the wing factions. It's
     more a matter of which wing candidate is preferred by the
     CWs's voters.

     That's why I've been saying that IRV is fine for you if
     you're majority-favored.

     If the CWs's voters transfer the other way, then you aren't
     in a mutual-majority, and then, for you, IRV is then no
     better than Plurality.

     Many of us have been explaining that to Rob Richie for the
     past 30 years or so.

-In systems like approval and score, the CW may or may not

     win under "honesty" (however defined). Arguably, if they do
     not, they should not.

     (endquote)

     Correct. When sincerely-voted Approval chooses differently
     from Condorcet, it's choosing socially better.

     Sure, not choosing the CWs got IRV repealed in Burlington.

     Not electing the CWs results in a majority who'd prefer a
     different result.

     But I think IRV was repealed for more than that:

     Approval let's people protect the CWs, without
     favorite-burial,  if that were what they want to do.  ...and
     I suggest that it isn't, because electing from your top-set
     is usually more important than electing the best particular
     individual candidate you can.

     CWs protection is more for rank methods, which are about
     choosing _among_ your top-set, to elect the best particular
     candidate you can.

     (But see my earlier post yesterday, about that.)

     If you have a top-set, then, by definition, electing from it
     is the important thing.

     Approve (only) your top-set.

     (More about that in my post yesterday)

     But, if it turned out to be really important to avoid having
     a majority who'd prefer a different result, then that  could
     be a reason for voters in Approval to slightly modify their
     voting to avoid approving past the expected CWs (CWse).
     ...though that would lower your Pt.

     When approving your top-set, you'd just stop short of
     approving past the CWse.

     Yesterday, too, I spoke of the possibility of your
     wing-faction having a social agreement to that effect.

     What you're saying doesn't contract what I've been saying.

     (endquote)

     Both, if people are trying for the best candidate they can
     get. Then obviously the smaller wing should support the CWs,
     and the CWs's voters should plump.

     But I don't suggest that goal for Approval, for the reasons
     stated above, & in earlier posts.

-In Condorcet systems, the CW wins under honesty by

     definition. But under SHOS, any CD-compliant method gets the
     wrong answer.

     No. In wv, a CWs isn't vulnerable to truncation. S/he still
     wins. ...the right answer in such a method.

     With burial, a potentially successful buial can succeed or
     fail, depending on whether the CWs's voters plump. Either
     way, the CWs doesn't win.

     (You wrote):

     ; the strategy is effective if the CW faction plumps, and
     backfires if the CW faction cooperates with the weaker wing.
     Note that even a strategy backfire here is not in my opinion
     a "good" result; because the strategy has some chance of
     winning, it will be sometimes attempted. Strategic backfire
     is a good thing if it discourages the strategy, but a bad
     thing if it actually occurs.

     Yes, that's what makes Condorcet at least a bit questionable.
     ...especially with the possibility of the perpetual burial
     fiasco.

     But it can probably be argued that, with rank methods' goal
     of getting the best individual candidate you can get, wv
     strategy improves on Bucklin, because, even if people
     misjudge who the CWs is, and so hir voters don't plump, the
     mere threat of plumping could be enough to deter burial,
     because the would-be buriers don't have better information
     than the defenders have.

-In most basic Bucklin systems, the CW faction must

     defensively plump to counteract SHOS.

     Yes, in Bucklin, if you aren't majority-favored, and if you
     rank sincerely, and if the CWs's voters don't plump, then
     that can result in the election of someone in your bottom-set.

     (You wrote):

-In a system like SARA, in most cases, even if the CW does

     not defensively plump, the weaker wing can give enough
     support to the CW to protect them from SHOS, without having
     to rate them equal-top. (If the CW is only barely a CW, the
     weak wing may have to rate equal-top for a successful defense
     in this case. However, I think that very tightly-balanced
     situations like this are not a large concern.)

     (endquote)

     That makes me sit up & take notice, because such an
     improvement on Bucklin strategy, while keeping FBC, would be
     major, & could outweigh the lack of CD enough to compete with
     the best methods.

Michael, you're arguing that certain kinds of utility or disutility are
more important than others. As a human being with my own judgment and
morals, I'd agree with you. But it's not just impossible, but actively
counterproductive, to try to build that kind of judgment and morals into a
voting system. If a voting system weights certain kinds of ballots more,
sophisticated voters will strategically cast that kind of ballots, and
unsophisticated voters will be ignored.

VSE (aka BR) is, in fact, the right target to aim at. It does not include
any judgment or morals, but, by an argument similar to the Condorcet Jury
Theorem, in the long run it's got the best chance of agreeing with a system
with did. To take your specific example: there are a lot more homeless
people than billionaires, so in general a democratic election system will
(correctly) weight the preferences of homeless people above those of
billionaires. (And if the billionaires can successfully trick all the
homeless people into thinking they prefer a candidate who will actually
serve the billionaires, there's nothing the voting system per se can do
about that.)

Jameson--

You said that SARA does particularly well by VSE.

But VSE is: (winner's SU)/(average SU among candidates)

...where SU is social utility.

...which is some constant minus BR.

But I've just told why BR is no good as a measure of the rightness or
goodness of an outcome.

Take a dollar from a homeless man and give it to a billionaire? That's a
negative change, because changes in greater disutilities are more important

Also, a given amount of money is worth more in utility to a poor person than a rich person, so Michael's analogy of taking a dollar from a homeless person and giving it to a billionaire doesn't work. I know he gave a previous example where the billionaire gets a yacht or something and it does get more debatable at that point.
But I don't think the maximum minimum utility is necessarily even the best principle to use anyway. There are good arguments for maximising average utility. If I am given 100 dollars, then there is an amount of money that I would gamble that for on a coin flip, or where I'd call them equivalent. Let's say I decide that I'd gamble it for anything more than 300 dollars. That's the same as me saying that for me the difference in utility between 0 and 100 dollars is the same as the difference between 100 and 300 dollars. It is also equivalent to saying that if there are two people with the same utility ratings as me, it's as good to give one of them 300 dollars as it is to give each of them 100 dollars. (Obviously you can argue about loss of utility through envy and perceived unfairness, but that's a separate issue - you don't need to tell the loser what happened.)
I have the same intuitions about rich/poor people, but you need a logically consistent framework as well as intuitions.

A change in a large disutility is more important than the same change in a
small disutility.

As a human being with my own judgment and morals, I'd agree with you. But
it's not just impossible, but actively counterproductive, to try to build
that kind of judgment and morals into a voting system. If a voting system
weights certain kinds of ballots more, sophisticated voters will

Of course. That's why I'd only suggest D2, D3, Dexp or Dhyp for a
completely honest and altruistic ideal utopian electorate. .

I like Score-Voting, and I completely agree with CES's advocacy of it,
along with Approval. But minimizing BR definitely isn't what justifies
Score.

As soon as you speak of the social rightness of BR minimization, then
you're already entering the realm of ideal morality & ethics. In that
realm, BR definititely isn't it, because, obviously, changes to a large
disutility are more important than changes to a small disutility.

Approval has a social optimization when people approve only their top-set.
Not utopian, but attainable with any electorate.

In Utopia, for specific action decisions, or maybe for some policy-choices,
we could do better with D2, D3, Dexp or Dhyp. Approval would be fine for
electing a candidate or party.

But, because Utopia isn't here (and legitimate elections aren't here
either), then of course it isn't an essential thing to reach agreement on
now.

, but, by an argument similar to the Condorcet Jury Theorem, in the long
run it's got the best chance of agreeing with a system with did.

Could you reword that?

To take your specific example: there are a lot more homeless people than
billionaires, so in general a democratic election system will (correctly)
weight the preferences of homeless people above those of billionaires.

Yes, so democracy, if we had it, would give a good result, even without
utopian altruism.

(And if the billionaires can successfully trick all the homeless people
into thinking they prefer a candidate who will actually serve the
billionaires, there's nothing the voting system per se can do about that.)

There's a lot that honest, open media can do about that. Billionaires'
media can & do convince people that Hillary, her corruption, her bad
policies, is the best they can get, but, that position wouldn't hold up at
all in a society in which the media are honest, open, participatory, &
agenda-free.

Anyway, when the elections are illegitimate due to unverifiable
vote-counting, there's no particular reason to believe that the voters and
how they vote have any role in public policy..

My overall point is that, while VSE does not directly and precisely measure
the true "goodness" of the election outcome, if done carefully and if
assumptions are varied, it gives us the best and least-biased measure we
have of that goodness. If you want to criticize it, propose an alternative
framework for evaluating voting systems.

Michael, you're arguing that certain kinds of utility or disutility are

As a human being with my own judgment and morals, I'd agree with you. But
it's not just impossible, but actively counterproductive, to try to build
that kind of judgment and morals into a voting system. If a voting system
weights certain kinds of ballots more, sophisticated voters will
strategically cast that kind of ballots, and unsophisticated voters will be

Of course. That's why I'd only suggest D2, D3, Dexp or Dhyp for a
completely honest and altruistic ideal utopian electorate. .

would be fine for electing a candidate or party.

But, because Utopia isn't here (and legitimate elections aren't here

run it's got the best chance of agreeing with a system with did.

Could you reword that?

To take your specific example: there are a lot more homeless people than
billionaires, so in general a democratic election system will (correctly)
weight the preferences of homeless people above those of billionaires.

Yes, so democracy, if we had it, would give a good result, even without
utopian altruism.

(And if the billionaires can successfully trick all the homeless people
into thinking they prefer a candidate who will actually serve the
billionaires, there's nothing the voting system per se can do about that.)

There's a lot that honest, open media can do about that. Billionaires'
media can & do convince people that Hillary, her corruption, her bad
policies, is the best they can get, but, that position wouldn't hold up at

example shows.

Yes, D2, D3, Dexp & Dhyp are arbitrary.

Well, maybe D2 isn't so arbitrary, when it says that the importance of
changing a disutility is proportional to the magnitude of the disutility.

But D2, D3, Dexp & Dhyp all resemble what we know to be right. ...what we
intuitively and subjectively know to be right.  And the basis of
ethics/morality is intuitive and subjective.

If you want to criticize it, propose an alternative framework for
evaluating voting systems.

That's what I've been doing.

For one thing, I used D1, D2, D3, Dexp & Dhyp to evaluate the
election-result in Forest's example. They all choose candidate D in the
example., suggesting that D is the right choice by the best ethical/moral
standards.

Of course I claim that D1 isn't the good measure that the others are. If
the others agreed with eachother but not with D1, then I'd say that their
conclusion is the one that is right.

I've also been saying that voting systems should be evaluated according to
how little a voter needs insincere strategy to make hir best effort to
achieve what s/he wants to achieve.

I suggest that, if you have a top-set, then electing from that top-set is,
by the definition of a top-set, the most important voting-goal for you.

Though it does't match the "sincerity" definition that I use with criteria,
I suggest that top-voting one's top-set is sincere in a meaningful sense.

A lot of people want to vote among their top-set too. I've been arguing
that, in general, doing so lowers their Pt (probability of electing from
their top-set), and is therefore suboptimal.

But I recognize that people might want rankings, or need them for reasons
that I've described in previous posts. In a method that strictly or
effectively meets MMC, a majority-favored (MF) voter can safely rank
sincerely, choosing among hir top-set, if the other members of hir
mutual-majority (MM) do so too.

But, for one thing, you can't always be sure if you're MF, and guessing
that you are must result in a suboptimal ballot.

For another thing, not everyone will be MF, and so that takes some of the
importance away from MMC.

These considerations take away the advantages of rank methods over Approval.

...except that there remains the fact that MMPO meets Weak CD, in addition
to FBC, and its Strong CD failure is mitigated by its deterrence of burial.

If you aren't MF, then ranking is suboptimal, so, in Bucklin or MMPO it
would be better to approval-vote, to equal-top-rank your top-set.

That's why I claim that FBC, so that top-voting one candidate won't undo
the benefit of top-voting another candidate, is necessary, based on the
above standards for evaluating voting-systems.

But, if some people will want to rank anyway, then it becomes desirable to
minimize the insincere strategy that they need, to elect from their
top-set, or just to elect the best individual candidate they can (which is
why they want to rank).

The CWs is the best individual candidate that they one can get. Also, the
CWs is maybe most likely (but certainly not necessarily) the candidate who
is in the most people's top-set. So, if you aren't MF, then at least it's
in your interest to elect the CWs.

So I've been evaluating methods according to how much insincere strategy is
needed to protect the CWs's win.

So yes, I've been proposing an alternative framework for evaluating
voting-systems.

I've tweaked the wording for SARA again. The only substantive changes
in outcome from this new wording is the change from "50 points or more" to
"more than 50 points".

Here's the latest wording, in 3 steps:

Support Accept Reject Abstain (SARA) works as follows:

1. *Voters can support, accept, reject, or abstain on each
candidate. Default is abstain. Candidates get 2 points for each percent of
"support" and 1 point for each percent of "accept", for a total of 0-200
points.*
   - *"Support" the best candidates (perhaps a quarter of them),
   "reject" the worst (perhaps half of them). "Accept" and "abstain" are for
   the ones in the high middle range. For those, "accept" if you want to help
   them beat somebody worse, and "abstain" if you could live with them but are
   hoping for somebody better.*
2. *Eliminate any candidates rejected by over 50%, unless that
leaves no candidates with over 50 points.*
   - *If possible, the winner shouldn't be somebody opposed by a
   majority. But this shouldn't end up defaulting to a candidate who couldn't
   at least get accepted by over 1/2 or supported by over 1/4 (as in, a
   majority subfaction of a divided majority, such as Nashville voters in the
   example below).*
3. *Highest points wins. In case of a tie, fewest rejections wins.*
   - *This finds the candidate with the widest and deepest
   support.*

Support Accept Reject Abstain voting works as follows:

- Voters can support, accept, reject, or abstain on each
candidate. Default is abstain.
- Call a candidate "acceptable" if they are rejected by 50% or
less and supported or accepted by over 25%. If any candidates are
acceptable, eliminate all who aren't.
- Give remaining candidates 2 points for each "support", 1 point
for each "accept", and half a point for each "abstain". Highest points wins.

This moves a bit away from the Bucklin roots of MAS, but it further
reduces the instability of cooperation in a CD scenario.

For one thing, I used D1, D2, D3, Dexp & Dhyp to evaluate the election-result in Forest's example. They all choose candidate D in the example., suggesting that D is the right choice by the best ethical/moral standards. Of course I claim that D1 isn't the good measure that the others are. If the others agreed with eachother but not with D1, then I'd say that their conclusion is the one that is right. I've also been saying that voting systems should be evaluated according to how little a voter needs insincere strategy to make hir best effort to achieve what s/he wants to achieve. I suggest that, if you have a top-set, then electing from that top-set is, by the definition of a top-set, the most important voting-goal for you. Though it does't match the "sincerity" definition that I use with criteria, I suggest that top-voting one's top-set is sincere in a meaningful sense. A lot of people want to vote _among_ their top-set too. I've been arguing that, in general, doing so lowers their Pt (probability of electing from their top-set), and is therefore suboptimal. But I recognize that people might want rankings, or need them for reasons that I've described in previous posts. In a method that strictly or effectively meets MMC, a majority-favored (MF) voter can safely rank sincerely, choosing among hir top-set, if the other members of hir mutual-majority (MM) do so too. But, for one thing, you can't always be sure if you're MF, and guessing that you are must result in a suboptimal ballot. For another thing, not everyone will be MF, and so that takes some of the importance away from MMC. These considerations take away the advantages of rank methods over Approval. ...except that there remains the fact that MMPO meets Weak CD, in addition to FBC, and its Strong CD failure is mitigated by its deterrence of burial. If you aren't MF, then ranking is suboptimal, so, in Bucklin or MMPO it would be better to approval-vote, to equal-top-rank your top-set. That's why I claim that FBC, so that top-voting one candidate won't undo the benefit of top-voting another candidate, is necessary, based on the above standards for evaluating voting-systems. But, if some people will want to rank anyway, then it becomes desirable to minimize the insincere strategy that they need, to elect from their top-set, or just to elect the best individual candidate they can (which is why they want to rank). The CWs is the best individual candidate that they one can get. Also, the CWs is maybe most likely (but certainly not necessarily) the candidate who is in the most people's top-set. So, if you aren't MF, then at least it's in your interest to elect the CWs. So I've been evaluating methods according to how much insincere strategy is needed to protect the CWs's win. So yes, I've been proposing an alternative framework for evaluating voting-systems.

Yes, I added that chance for that reason.

But I don't think the maximum minimum utility is necessarily even the best
principle to use anyway. There are good arguments for maximising average
utility.

I haven't heard one. The argument below doesn't successfully show that.

If I am given 100 dollars, then there is an amount of money that I would
gamble that for on a coin flip, or where I'd call them equivalent. Let's
say I decide that I'd gamble it for anything more than 300 dollars. That's
the same as me saying that for me the difference in utility between 0 and
100 dollars is the same as the difference between 100 and 300 dollars. It
is also equivalent to saying that if there are two people with the same
utility ratings as me, it's as good to give one of them 300 dollars as it
is to give each of them 100 dollars.

It results in the same total utility. To say that that means its just as
good, circularly assumes what you seek to show.

You haven't shown that giving one person $300 and giving the other person
nothing is as good as giving $100 to each. ...you've shown only that the
total utility is the same.

You can't justify taking a dollar away from a homeless man who badly needs
it, and giving another yacht to a billionaire.

I have the same intuitions about rich/poor people, but you need a
logically consistent framework as well as intuitions.

I don't deny that logic can't apply to some ethical/moral questions. But
logic has nothing to do with the basis of ethical and moral choices.

The basis of ethics & morality is intuitive & subjective, not logical.

Michael, you're arguing that certain kinds of utility or disutility are
more important than others. As a human being with my own judgment and
morals, I'd agree with you. But it's not just impossible, but actively
counterproductive, to try to build that kind of judgment and morals into a
voting system. If a voting system weights certain kinds of ballots more,
sophisticated voters will strategically cast that kind of ballots, and
unsophisticated voters will be ignored.

VSE (aka BR) is, in fact, the right target to aim at. It does not include
any judgment or morals, but, by an argument similar to the Condorcet Jury
Theorem, in the long run it's got the best chance of agreeing with a system
with did. To take your specific example: there are a lot more homeless
people than billionaires, so in general a democratic election system will
(correctly) weight the preferences of homeless people above those of
billionaires. (And if the billionaires can successfully trick all the
homeless people into thinking they prefer a candidate who will actually
serve the billionaires, there's nothing the voting system per se can do
about that.)

2016-10-25 18:41 GMT-04:00 Michael Ossipoff email9648742@gmail.com:

Jameson--

You said that SARA does particularly well by VSE.

But VSE is: (winner's SU)/(average SU among candidates)

...where SU is social utility.

...which is some constant minus BR.

But I've just told why BR is no good as a measure of the rightness or
goodness of an outcome.

Take a dollar from a homeless man and give it to a billionaire? That's a
negative change, because changes in greater disutilities are more important
