Juho:

In your explanation of "minimizing violated pinions", you described
your own interpretation of proportionality.

If you're interested in proportionality, the matter of optimally equal
representation per voter, I've told you where to read about it.

If you're interested in minimizing violated opinions, then PR is not for you.

If I were doing PR, I'd be glad to instruct you in proportionality.
And, if so, I'd be glad to walk you through the subject and and
explain to you your specific errors. But, as I said, I no longer do
PR.

As it is, I can only refer you to the sources that I cited. Read them
conscientiously, and don't cling to your assumptions.

It's arrogant to believe that you're more qualified in a subject, when
you don't want to take the time to study it.

Don't cheat yourself in that way.

That's my best advice for you.

Now, forgive me if I say a few things that I've already said. I'm
saying it with other things that I haven't said.

For allocating seats to parties:

I used to prefer Sainte-Lague (as recently as earlier in this
discussion), because I felt that if you want PR at all, then you might
as well get the best pure proportionality.

Also, I guess I was influenced by others, who believed that the Repubs
& Dems would remain the big 2, and wanted the small parties to get
their fair share. I bought into that feeling.

But I have more confidence in the voters than that. That's why I
prefer single-seat districts, or at least the use of a good
single-winner method instead of PR. I believe that if some of the
small parties are better, then they won't remain small for long, when
Approval is in use. But, as I said, I have nothing against PR--I just
don't consider it necessary at all. But of course PR would be a lot
better than Plurality or Runoff. I'm convinced that if the voters can
support what they really like, then there will be all the improvement
we could ask for.

As I said, PR isn't viable here anyway, because it's a drastically
different notion of representation and govt--whereas a better
single-winner method is nothing other than a better way of doing what
we already do--electing candidates to single-member districts.

Because I don't consider PR necessary anyway, For allocating seats to
parties, I now prefer d'Hondt, with its balance between
proportionality and majoritarianism. (and, for STV, the Droop quota,
for the same reason). Someone who doesn't consider PR necessary at all
has no reason to insist on the purest all-out un-compromised Plurality
of Sainte-Lague.

But it just depends on what you want. I have no criticism of
Sainte-Lague, or for the goal of optimally equal representation per
person that requires  Sainte-Lague.

In fact, as I said, any of the PR systems and methods would be fine.

Allocating seats to districts:

That's a whole other ballgame. For that application, there's really no
room for debate. Living in a some particular district is very
different from preferring an unpopular party. If the party that you
like best is unpopular, then that's the way it goes. But, regardless
of which district you reside in, you have an obvious right to equal
representation. To the greatest extent possible, you have a right to
as much representation as anyone else. That's why Sainte-Lague is the
way to allocate seats to districts.

When allocating seats to districts, the question is: Do you or do you
not want as much representation as the other people? If so, then the
answer is Sainte-Lague. But, if you're happy with avoidably less
representation than other people have, that's your business, and it
isn't for me to tell you what you should want.

Yes. Voter freedom is limited to candidate given (theme) rankings. There are no 
voter specified rankings that could "jump between different branches".

Probably parties will decide which candidates they will take on their lists (in 
all methods). Even if that is the case, candidates could be allowed to freely 
position themselves in the tree within the party specific branch. Any group of 
(already qualified) candidates could in this approach establish a new 
"theme"/subgroup under the already existing ones.

Alternatively parties would have full control of allocation of candidates in 
the tree wihin the party branch. In this case parties could plan the optimal 
tree structure for them. Candidates could be forced to groups that the party 
considers to be strategically best. Also in VPR parties could try to force 
their candidates to give certain kind of rankings (e.g. rank own party 
candidates first, or rank party favourites first).

Maybe one should ban or discourage branches that have no political meaning 
(e.g. branches "A" and "B" that contain candidates with similar political 
opinions). Only clear political messages would be allowed, e.g. "green", "pro 
nuclear power". Whatever the rules are, the system should not be allowed to 
degrade to a mechanism where the party tries to dictate which candidates will 
be elected and which ones not. The approaches might be different in different 
societies. One robust approach would be to allow some officials/court decide 
which branches are proper political branches and which ones are not, and must 
therefore be flattened/combined.

One could also have rules that encourage parties to use a good tree stratcture 
(e.g. rules that allow more candidates in "good" trees).

Ground up? Does that refer to candidate driven decisions instead of party

Trees show promise for eliminating voting paradoxes by limiting voter
freedom. However, you'd have to actually develop a system for building the
trees. Just assuming that they exist doesn't cut it; that hides hairy
strategy and coordination problems for the candidates, factions, and
parties.

Also, the way trees work is by privileging certain dimensions of a
candidate over others. One set of dimensions which is almost sure to get
short shrift is quality – that is, intelligence, honesty, hard work, you
name it.

In other words, I'd be interested in reading about a system built from the

speculate that VPR would be even more perfect if we just sprinkled magic
tree dust on it.

It is easy to fill the ballot in VPR. It is one step more difficult to check 
the preferences of the candidates and decide whom to vote. If one goes one step 
further in this simplification path, one might end at tree voting. We could 
have a candidate that belongs to the free rifle group of the green group of the 
socialist party. That's close to open lists but allows voters to clearly 
position themselves to the level of a full binary tree, provides 
proportionality also within the parties, allows voters to see easily what each 
candidate intends to stand for, and is quite strategy free. Voters may vote a 
green socialist or a socialist green, depending on which criterion is more 
important to them. One can say that trees are policy oriented (candidates rank 
themes) while VPR is person oriented (candidates rank candidates).

This is very similar to SODA. It is simpler to explain (though not as much
as you might think, because you still have to explain the underlying ranked
system used), but I think worse in several regards. Still, I'd agree that
it is a very good method overall.

SODA effectively allows withdrawal in its default form.

Pretty soon, you'd have all permutations available, and it becomes just
equivalent to the underlying method. Perhaps a bit simpler for a trusting
voter, a bit more complicated for a non-trusting voter.

Ouch. Suddenly the ballot design is a nightmare. Don't like this one at all.

No, SODA is simpler for voters. You can unintentionally spoil your ballot
in VPR, but not in SODA.

Assuming the candidates are honest, yes. However, I think I see ways that
rational candidate strategy could still give pathological results, in
situations that SODA handles well.

Similar to SODA in this regard, and yes, this is an important strength.

As with SODA in this sense, though SODA has a failsafe so that if this kind
of thing leads to a total "surprise" winner, perhaps because of dishonest
strategy, at least one other candidate will be able to back out, letting
their stronger opponent win instead of the dark horse they'd said they
preferred (perhaps without proper vetting).

Again, I think this is a very good method; I just think that SODA is better.

[EM] Declaration's policy on single-mark ballots (was Re: Do any of you have any thoughts about California's top-two primary?)

2012-06-10 Thread Steve Eppley
It's a bad idea for the Declaration to 
denounce all single-mark ballot methods, 
because one of them--Vote for a Published 
Ranking (VPR)--has desirable properties that 
distinguish it from the others. (One can also 
make an argument that VPR is better than many 
voting methods that require more complicated 
ballots.)


 VPR:
 Two weeks before election day, each 
candidate publishes a top-to-bottom ordering
 of all the candidates. (Any candidate 
who fails to meet the deadline will be treated
 as if s/he'd ranked him/herself on top 
and all others tied for bottom.)


 On election day, each voter simply 
selects one candidate.


 Then each vote is treated as if it were 
the ordering published by its selected
 candidate.  These orderings are tallied 
by a good preference order algorithm

 to determine the winner.

Some interesting variations:
1. Give each candidate the opportunity to 
withdraw after the vote totals are published; 
withdrawn candidates will be dropped to the 
bottom of each ordering before the orderings 
are tallied.  With this option, tallying 
algorithms such as plurality rule & instant 
runoff would become nearly as good as 
condorcet algorithms because withdrawal would 
mitigate their vote-splitting problem. (Borda 
would still be terrible due to its clones 
problem.)  Also, withdrawal would be useful 
in presidential elections--with VPR and other 
voting methods--to help candidates avoid 
fragmenting the Electoral College.
2. Technology permitting, allow each voter to 
select an ordering published by a candidate 
or by a non-government organization (NGO).  
Some example NGOs: the New York Times, the 
Sierra Club, the National Rifle Association...
3. Technology permitting, let each voter 
modify the ordering published by her selected 
candidate, before submitting it as her vote.


Obviously, being a "single-mark" method, VPR 
maximizes simplicity.  Yet it can be expected 
to handle the vote-splitting problem well.  
It ought to typically allow each voter to 
vote for her sincere favorite, assuming her 
favorite publishes an ordering the voter 
considers reasonable. (Or strategically 
reasonable.  If an election has a strategy 
problem, the voter's favorite can handle it 
by publishing a strategic ordering, or by 
withdrawing if necessary, if withdrawal is an 
option.)


Also, VPR would make it easier for good 
candidates to win without spending a lot of 
money, since they can win by persuading other 
candidates to rank them over worse 
candidates.  For example, Centrist might 
persuade Left to rank Centrist over Right, 
and Right to rank Centrist over Left.  
Furthermore, an honest centrist might 
persuade Left & Right to rank her over 
corrupt centrists, and when she can't due to 
Left & Right also being corrupt, the corrupt 
orderings they publish would presumably 
attract negative attention during the two 
weeks preceding the election, reducing their 
votes.
