The election methods trade-off paradox/impossibility theorems paradox.

The election methods trade-off paradox/impossibility theorems paradox.

For the sake of argument, suppose a trade-off theory of elections that
there is no consistently democratic electoral system: the impossibility
supposition.

That supposition implies some conception (albeit non-existent) of a
consistently derived right election result.

If there is no such measure, then there is no standard even to judge
that there is a trade-off between electoral systems.

Suppose there is a consistent theory of choice, setting a standard by
which electoral systems can be judged for their democratic consistency.

It follows that the election result will only be as consistent as the
electoral system, and there is no pre-conceivably right election result,
because that presupposes a perfection not given to science as a
progressive pursuit.

I kinda don't accept this paradox. Just to compare the form of a election
method paradox statement: Arrow's theorem was that given a set of desired
properties and the constraint of rankings ballots, those set of desirable
properties could not all be simultaneously fulfilled. One can almost
trivially step outside of that paradox by eliminating the constraint of the
rankings ballot.

My model of understanding people and elections is a utilitarian one. A
person derives some amount of utility from the outcome of an election and
everyone is apportioned the same share of utility which we might count as
0..1 or -1..1 . These model persons can be summed up and and a global
social utility calculated. The ideal election method perfectly knows every
person and elects the true global social utility maximizing candidate. This
sounds an awful lot like score voting. But then we have to start to
complicate the model with imperfect knowledge of a voter's utility, the
imperfect expression of that on a ballot, strategic ballot casting rather
than honest, messy computation and practical administration issues of
running an election in the real world, and so on. So we might wind up with
a best practical method that isn't just simple score voting.

But I still believe there is a pragmatic 'best' method, we have techniques
for evaluating that, and we should do this and put something up in the real
world. Personally I'll take a rankings ballot that's Condorcet counted with
any cycle resolution method as 'good enough' and practically applicable;
and tinkering around the edges for a slightly better method is fun
mathematical curiosity but I'd also like to get some laws passed.

What do you think of my model statement?
Is there a more formal statement of limitations you were heading towards?

Brian Olson,

Where we differ is that I do not see ranked choice as a constraint.
Single order choice, the x-vote is the constraint on ranked voting as a
multiple-order choice.
The problem with election methods, practical and theoretical is that
they impose constraints on the voters freedom of choice, in one way or
another, and so are that much less true election methods.
(A minor example, the classic objections to cumulative voting seem to
apply to some apprently modern versions or variations.)

When Condorcet and Borda, disagreed on the best way to conduct a count
of preference voting, Laplace decided in favor of Borda. (I grant you
that Condorcet has information value, when weighted. But I am not well
informed on this approach and know of no convincing reason why it should
be adopted or how you would persuade the public of that.) JFS Ross
explained that Laplace favored Method Borda because higher preferences
were more important and should count more. The Gregory method removes
the objection to Borda of "later harm." This is the direction I have
followed (weighted count of ranked choice), following on from where Meek
method STV leaves off.

Compared to a rankings ballot, a ratings ballot contains more information
about a voter's preference or utility for the available choices.
I can say
A > B > C > D
or I can say with more detail
A = 1.0; B = 0.9; C = 0.1; D = 0.0

If there is more information available, it is possible for an election
algorithm to use that information and more accurately represent the voters
and find the greater global utility winner.

If we had a specially insightful rational bayesian voting populace we might
ask them for their confidence interval of how sure they are are about each
choice and get more information still.
A = 1.0 (e=.3); B = 0.9 (e=.1), C = 0.1 (e=0.5), D = 0.0 (e=0.1)

And then we'd work out an election algorithm to maximize the expected value
of the global utility over the known voter utility distributions.

Compared to a rankings ballot, a ratings ballot contains more information

about a voter's preference or utility for the available choices.

I can say

A > B > C > D

or I can say with more detail

A = 1.0; B = 0.9; C = 0.1; D = 0.0

If there is more information available, it is possible for an election

algorithm to use that information and more accurately represent the voters

and find the greater global utility winner.

but voters can skew that information quantitatively and, if they want to be tactical, insincerely.
how does the voter know that by rating Candidate B with 0.9 and not lower, that he is not helping this candidate beat his favorite, Candidate A? �maybe it should be 0.8. �or
0.5.
while Score voting requires too much information from the voters (making them act as a trained expert and consider quantitatively how candidates should be rated as if they are an Olympic ice skating judge) and while Approval doesn't get enough information from voters (does not
differentiate preference between two "approved" candidates), there has always been the problem of either Score voting or Approval voting facing the voter about what to do with their second choice (Candidate B). �how much juice should the voter give to Candidate B if they want B to
beat C but do not want B to beat A? �(and for Approval, the question is, having the same concern, shall the voter "approve" B or not?)

Score and Approval cannot answer that question in any simple manner. �but with Ranked-Choice the answer is clear.
and the other problem with Score is the "One-Person-One-Vote" standard. �if i really, really, really like Candidate A over Candidate B and you only sorta like B
over A by just a little bit, it should not matter to what disparate degree we like our candidates. �your vote for B should weigh just as much as my vote for A, even if my excitement for A exceeds your excitement for B. �that's what "one-person-one-vote" means.
i still just
do not get why Score and Approval (in application to governmental elections) have the following they do have.
bestest,
r b-j

If we had a specially insightful rational bayesian voting populace we might

ask them for their confidence interval of how sure they are are about each

choice and get more information still.

A = 1.0 (e=.3); B = 0.9 (e=.1), C = 0.1 (e=0.5), D = 0.0 (e=0.1)

And then we'd work out an election algorithm to maximize the expected value

of the global utility over the known voter utility distributions.

Brian Olson,

Where we differ is that I do not see ranked choice as a constraint. Single

order choice, the x-vote is the constraint on ranked voting as a

multiple-order choice.

The problem with election methods, practical and theoretical is that they

impose constraints on the voters freedom of choice, in one way or another,

and so are that much less true election methods.

(A minor example, the classic objections to cumulative voting seem to

apply to some apprently modern versions or variations.)

When Condorcet and Borda, disagreed on the best way to conduct a count of

preference voting, Laplace decided in favor of Borda. (I grant you that

Condorcet has information value, when weighted. But I am not well informed

on this approach and know of no convincing reason why it should be adopted

or how you would persuade the public of that.) JFS Ross explained that

Laplace favored Method Borda because higher preferences were more important

and should count more. The Gregory method removes the objection to Borda of

"later harm." This is the direction I have followed (weighted count of

ranked choice), following on from where Meek method STV leaves off.

running an election in the real world, and so on. So we might wind up with

a best practical method that isn't just simple score voting.

But I still believe there is a pragmatic 'best' method, we have techniques

for evaluating that, and we should do this and put something up in the real

world. Personally I'll take a rankings ballot that's Condorcet counted with

any cycle resolution method as 'good enough' and practically applicable;

and tinkering around the edges for a slightly better method is fun

mathematical curiosity but I'd also like to get some laws passed.

What do you think of my model statement?

Is there a more formal statement of limitations you were heading towards?

For the sake of argument, suppose a trade-off theory of elections that

That supposition implies some conception (albeit non-existent) of a

consistently derived right election result.

If there is no such measure, then there is no standard even to judge that

there is a trade-off between electoral systems.

Suppose there is a consistent theory of choice, setting a standard by

which electoral systems can be judged for their democratic consistency.

It follows that the election result will only be as consistent as the

because that presupposes a perfection not given to science as a progressive

Ah yes, the old criticism against cumulative voting (made for instance
by Enid Lakeman) is relevant here. Cumulative votes count against each
other.
I suppose the basic objection is that voters cannot be also their own
counters, because that is a function of peoples combined votes, not of
individual voters.

BTW I didn't answer your previous question about a formal basis for my
election method. It is based on work by SS Stevens on the scales of
measurement, published in "Science" in the 1940s. Long ago, when  I was
a young man, Unesco gave me a copyright for this.

I was speaking only of ballots, and and in the abstract that some election
algorithm could take that information and make a good outcome of it.

I don't favor raw Score summation. It's strategy prone. For choices where
my honest vote might be [1.0, 0.8, 0.6, 0.4, 0.2, 0.0] I should probably
vote strategically [1.0, 1.0, 1.0, 0.0, 0.0, 0.0].

And if you don't like that and the varying vote power depending on how you
vote: I have a system for you!
"Instant Runoff Normalized Ratings" (IRNR)
Each ballot is normalized so that all ballots have the same magnitude. The
modified ballots are summed, and the choice with the lowest sumarry rating
is disqualified. Each ballot is then normalized again as if the
disqualified choice was not there, redistributing the vote across the
choices in proportion to the original ballot. The new modified ballots are
summed and the process is repeated until there are two choices remaining
and one choice wins over the other.

I think this works better with an honest ballot in the case where you like
some choice more than another 'just a little bit' or by whatever margin.

Compared to a rankings ballot, a ratings ballot contains more information
about a voter's preference or utility for the available choices.
I can say
A > B > C > D
or I can say with more detail
A = 1.0; B = 0.9; C = 0.1; D = 0.0

If there is more information available, it is possible for an election
algorithm to use that information and more accurately represent the

voters

and find the greater global utility winner.

but voters can skew that information quantitatively and, if they want to
be tactical, insincerely.

how does the voter know that by rating Candidate B with 0.9 and not lower,
that he is not helping this candidate beat his favorite, Candidate A?
maybe it should be 0.8.  or 0.5.

while Score voting requires too much information from the voters (making
them act as a trained expert and consider quantitatively how candidates
should be rated as if they are an Olympic ice skating judge) and while
Approval doesn't get enough information from voters (does not differentiate
preference between two "approved" candidates), there has always been the
problem of either Score voting or Approval voting facing the voter about
what to do with their second choice (Candidate B).  how much juice should
the voter give to Candidate B if they want B to beat C but do not want B to
beat A?  (and for Approval, the question is, having the same concern, shall
the voter "approve" B or not?)

Score and Approval cannot answer that question in any simple manner.  but
with Ranked-Choice the answer is clear.

and the other problem with Score is the "One-Person-One-Vote" standard.
if i really, really, really like Candidate A over Candidate B and you only
sorta like B over A by just a little bit, it should not matter to what
disparate degree we like our candidates.  your vote for B should weigh just
as much as my vote for A, even if my excitement for A exceeds your
excitement for B.  that's what "one-person-one-vote" means.

i still just do not get why Score and Approval (in application to
governmental elections) have the following they do have.

bestest,

r b-j

If we had a specially insightful rational bayesian voting populace we

might

ask them for their confidence interval of how sure they are are about

each

choice and get more information still.
A = 1.0 (e=.3); B = 0.9 (e=.1), C = 0.1 (e=0.5), D = 0.0 (e=0.1)

And then we'd work out an election algorithm to maximize the expected

value

of the global utility over the known voter utility distributions.

and, except for making examples to show how a system breaks (like a Proof
by Contradiction in mathematics), i just cannot see how judging the
comparative value of systems with simulated assumptions is helpful.  there
are not enough simulated cases to be able to consider how any system will
work under all conditions.

Brian Olson,

Where we differ is that I do not see ranked choice as a constraint.

Single

order choice, the x-vote is the constraint on ranked voting as a
multiple-order choice.
The problem with election methods, practical and theoretical is that

they

impose constraints on the voters freedom of choice, in one way or

another,

and so are that much less true election methods.
(A minor example, the classic objections to cumulative voting seem to
apply to some apprently modern versions or variations.)

When Condorcet and Borda, disagreed on the best way to conduct a count

of

preference voting, Laplace decided in favor of Borda. (I grant you that
Condorcet has information value, when weighted. But I am not well

informed

on this approach and know of no convincing reason why it should be

adopted

or how you would persuade the public of that.) JFS Ross explained that
Laplace favored Method Borda because higher preferences were more

important

and should count more. The Gregory method removes the objection to

Borda of

"later harm." This is the direction I have followed (weighted count of
ranked choice), following on from where Meek method STV leaves off.

trivially step outside of that paradox by eliminating the constraint of

My model of understanding people and elections is a utilitarian one. A
person derives some amount of utility from the outcome of an election

and

everyone is apportioned the same share of utility which we might count

as

0..1 or -1..1 . These model persons can be summed up and and a global
social utility calculated. The ideal election method perfectly knows

every

person and elects the true global social utility maximizing candidate.

This

sounds an awful lot like score voting. But then we have to start to
complicate the model with imperfect knowledge of a voter's utility, the
imperfect expression of that on a ballot, strategic ballot casting

rather

than honest, messy computation and practical administration issues of
running an election in the real world, and so on. So we might wind up

with

a best practical method that isn't just simple score voting.

But I still believe there is a pragmatic 'best' method, we have

techniques

for evaluating that, and we should do this and put something up in the

real

world. Personally I'll take a rankings ballot that's Condorcet counted

with

any cycle resolution method as 'good enough' and practically applicable;
and tinkering around the edges for a slightly better method is fun
mathematical curiosity but I'd also like to get some laws passed.

What do you think of my model statement?
Is there a more formal statement of limitations you were heading

towards?

The election methods trade-off paradox/impossibility theorems paradox.

For the sake of argument, suppose a trade-off theory of elections that
there is no consistently democratic electoral system: the impossibility
supposition.

That supposition implies some conception (albeit non-existent) of a
consistently derived right election result.

If there is no such measure, then there is no standard even to judge

that

there is a trade-off between electoral systems.

Suppose there is a consistent theory of choice, setting a standard by
which electoral systems can be judged for their democratic consistency.

It follows that the election result will only be as consistent as the
electoral system, and there is no pre-conceivably right election

result,

because that presupposes a perfection not given to science as a

progressive

pursuit.

I also have found it hard to believe that Score voting and Approval
voting are taken seriously.
There is a tradition of cumulative voting in one of the states, that,
not surprisingly, would not have compared badly with FPTP.
An American political science association uses Approval Voting. I take
that choice in itself to be a form of strategic voting. Neither looking
too bad with FPTP, nor looking too good, in the eyes of (gerrymandering)

I do agree that quantitative counts are better than qualitative counts
of "greater than". How much quantitative measurement extracted from the
voting data (rather than imposed on it) is a simple way to assess a
voting method's efficiency. Sooner or later, tho, the method has to
resort to less precisely based decisions of greater or lesser. This, by
the way, proves or shows that election results are generally
probabilistic rather than deterministic, and therefore cannot be
decisively judged by deductive standards of electoral efficiency (like
social choice theory).
My own election method (Binomial Transferable Vote) does not resort to
elimination of candidates during the count, to avoid a more or less
arbitrary plurality count (greater than) decision.

Compared to a rankings ballot, a ratings ballot contains more

 information

about a voter's preference or utility for the available choices.
I can say
A > B > C > D
or I can say with more detail
A = 1.0; B = 0.9; C = 0.1; D = 0.0

If there is more information available, it is possible for an

 election

algorithm to use that information and more accurately represent

 the voters

and find the greater global utility winner.

 but voters can skew that information quantitatively and, if they
 want to be tactical, insincerely.

 how does the voter know that by rating Candidate B with 0.9 and
 not lower, that he is not helping this candidate beat his
 favorite, Candidate A?  maybe it should be 0.8.  or 0.5.

 while Score voting requires too much information from the voters
 (making them act as a trained expert and consider quantitatively
 how candidates should be rated as if they are an Olympic ice
 skating judge) and while Approval doesn't get enough information
 from voters (does not differentiate preference between two
 "approved" candidates), there has always been the problem of
 either Score voting or Approval voting facing the voter about what
 to do with their second choice (Candidate B).  how much juice
 should the voter give to Candidate B if they want B to beat C but
 do not want B to beat A?  (and for Approval, the question is,
 having the same concern, shall the voter "approve" B or not?)

 Score and Approval cannot answer that question in any simple
 manner.  but with Ranked-Choice the answer is clear.

 and the other problem with Score is the "One-Person-One-Vote"
 standard.  if i really, really, really like Candidate A over
 Candidate B and you only sorta like B over A by just a little bit,
 it should not matter to what disparate degree we like our
 candidates.  your vote for B should weigh just as much as my vote
 for A, even if my excitement for A exceeds your excitement for B.
  that's what "one-person-one-vote" means.

 i still just do not get why Score and Approval (in application to
 governmental elections) have the following they do have.

 bestest,

 r b-j

If we had a specially insightful rational bayesian voting

 populace we might

ask them for their confidence interval of how sure they are are

choice and get more information still.
A = 1.0 (e=.3); B = 0.9 (e=.1), C = 0.1 (e=0.5), D = 0.0 (e=0.1)

And then we'd work out an election algorithm to maximize the

 expected value

of the global utility over the known voter utility distributions.

 and, except for making examples to show how a system breaks (like
 a Proof by Contradiction in mathematics), i just cannot see how
 judging the comparative value of systems with simulated
 assumptions is helpful.  there are not enough simulated cases to
 be able to consider how any system will work under all conditions.

Brian Olson,

The problem with election methods, practical and theoretical is

 that they

impose constraints on the voters freedom of choice, in one way

 or another,

and so are that much less true election methods.
(A minor example, the classic objections to cumulative voting

 seem to

apply to some apprently modern versions or variations.)

When Condorcet and Borda, disagreed on the best way to conduct

 a count of

preference voting, Laplace decided in favor of Borda. (I grant

 you that

Condorcet has information value, when weighted. But I am not

 well informed

on this approach and know of no convincing reason why it should

 be adopted

or how you would persuade the public of that.) JFS Ross

 explained that

Laplace favored Method Borda because higher preferences were

 more important

and should count more. The Gregory method removes the objection

 to Borda of

"later harm." This is the direction I have followed (weighted

 count of

ranked choice), following on from where Meek method STV leaves off.

My model of understanding people and elections is a utilitarian

 one. A

person derives some amount of utility from the outcome of an

 election and

everyone is apportioned the same share of utility which we

 might count as

0..1 or -1..1 . These model persons can be summed up and and a

 global

social utility calculated. The ideal election method perfectly

 knows every

person and elects the true global social utility maximizing

 candidate. This

sounds an awful lot like score voting. But then we have to start to
complicate the model with imperfect knowledge of a voter's

 utility, the

imperfect expression of that on a ballot, strategic ballot

 casting rather

than honest, messy computation and practical administration

 issues of

running an election in the real world, and so on. So we might

 wind up with

a best practical method that isn't just simple score voting.

But I still believe there is a pragmatic 'best' method, we have

 techniques

for evaluating that, and we should do this and put something up

 in the real

world. Personally I'll take a rankings ballot that's Condorcet

 counted with

any cycle resolution method as 'good enough' and practically

 applicable;

and tinkering around the edges for a slightly better method is fun
mathematical curiosity but I'd also like to get some laws passed.

What do you think of my model statement?
Is there a more formal statement of limitations you were

 heading towards?

The election methods trade-off paradox/impossibility theorems

 paradox.

For the sake of argument, suppose a trade-off theory of

 elections that

there is no consistently democratic electoral system: the

 impossibility

supposition.

That supposition implies some conception (albeit non-existent)

 of a

consistently derived right election result.

If there is no such measure, then there is no standard even to

 judge that

there is a trade-off between electoral systems.

Suppose there is a consistent theory of choice, setting a

 standard by

which electoral systems can be judged for their democratic

 consistency.

It follows that the election result will only be as consistent

 as the

electoral system, and there is no pre-conceivably right

 election result,

because that presupposes a perfection not given to science as

 a progressive

pursuit.

I do agree that quantitative counts are better than qualitative counts of "greater than". How much quantitative measurement extracted from the voting data (rather than imposed on it) is a simple way to assess a voting method's efficiency. Sooner or later, tho, the method has to resort to less precisely based decisions of greater or lesser. This, by the way, proves or shows that election results are generally probabilistic rather than deterministic, and therefore cannot be decisively judged by deductive standards of electoral efficiency (like social choice theory). My own election method (Binomial Transferable Vote) does not resort to elimination of candidates during the count, to avoid a more or less arbitrary plurality count (greater than) decision.
