Dear Greg,

I will give a new step-by-step exposition of FAWRB in a new thread 
during this day.



Most people say the majority criterion is a good one. I, for one,
doubt its importance. I was merely saying that a counter-criterion
inconsistent with the majority criterion hasn't really been offered.


That counter-criterion has been offered: "Every voter should have full 
control over the same amount of winning probability." Methods complying 
with this then should try to increase the efficiency by providing some 
means for anonymous cooperation.



umm... in any electoral method some subset will have absolute power...


What makes you think so? The simplest counter-example to your claim is 
Random Ballot.



Also, in ANY electoral method you can get useless votes.


Again: The simplest counter-example to this claim is Random Ballot.


For example, if I have 999 people supporting me under some
non-majoritarian method, 1 person voting against it won't make a hell
of a lot of difference. The 999 have complete power!


The question is not whether it makes "a hell of a lot of difference" but 
whether it makes a difference at all. In FAWRB, you would have incentive 
to provide that 1 person with some small amount of compensation in order 
to get her vote, too.



This is a gripe with democracy not with majoritarianism.


Nope. See above. It's all about *establishing* democracy!


Thinking outside the box, they could secede.


Yes, and that's a threat to society which could ultimately lead to anarchy.


Athenian democracy doesn't work. Sorry. Using a non-determinstic
method incurs massive flaws in real life.


Give examples, please. Athenian democracy worked well for the Athenians 
for two centuries.



Applying the same logic to majoritarian methods, every opinion has a
given probability of being a majority.


That probability being zero when the opinion is the minority opinion.


Yay we agree OMOV is trivial. Why do you keep bringing up violations
of OMOV then? 


I did never talk about OMOV, it was you who brought it up. Probably you 
misunderstood me.


Denying voters influence is an OMOV flaw. 


No it's not. Most majoritarian methods comply with OMOV and still deny 
the minority any influence. I'm asking myself how often I will have to 
repeat this obvious fact.



If there are a group of int(.5*voters)+1 people who vote X > non-X and
X is one and only one candidate, how does the minority express its
opinion w/o violating OMOV.


Er? You ask how they express their opinion? Well, on the ballot, of course?


They ARE better, just not intrinsically so. Specific violation of a
given property does not a perfect voting system make.


Nobody is claiming that since it would be ridiculous.


Is there ever an incentive not to secret contract? If so, is it significant?


To avoid this is exactly the task of the method designer. The method 
should be designed so that there are positive incentives to cooperate 
when the compromise is good enough.



I see... is this FAWRB?

Candidates have three statuses on a ballot: Favorite, Approved, Disapproved

I pick two ballots at random.

If there is a candidate that is favorite on both ballots, pick it.

If there is a candidate that is favorite on the first and approved on
the second, pick it.

If there is a candidate that is approved on the first and favorite on
the second, pick it.

If there is a candidate that is approved on both the first and second, pick it.

Otherwise pick the favorite on the first.


That's more or less what we call D2MAC, which is similar in spirit to 
FAWRB and achieves the task of electing a good compromise, too. The main 
difference is that with D2MAC compromise options which are only good but 
not *very* good have fewer chances than with FAWRB.



Ok now the actual criticism. I know that FAWRB is nondeterministic.
Here is why that is bad.

Factions (both unwilling to compromise):

A 55%
B 45%

you view A as gaining a "55% chance of victory".

This reasoning is flawed. Instead of viewing A as getting .55 victory
units, think of it as a random choice between two possible worlds:

A-world and B-world

A-world is 10% more likely to occur, however they share remarkable similarities.

In both worlds >=45% of the people had no say whatsoever.


They had a "say" in that they had a fair chance. In reality, chance 
occurs everywhere anyway. Picking an option is always a risky thing. 
When economists talk of utility and analyse preferences they almost 
always mean *expected* utility because the actual utility is the result 
of a random process.


Anyway, the point is that in your example people (if they use the right 
decision method) will have an incentive to find a compromise C which 
everyone likes a lot better that the 55%/45% lottery. So they will 
usually reduce the randomness by cooperation.



Now, you're reasoning apppears to stem from a simple observation...

The trick with his method is that neither A-world or B-world is likely
to actually occur.  It creates an incentive to find a compromise,
called say, AB-world.

If all voters vote reasonably, then the result is a high probability
that the AB option will be picked.

The utlities might be
. A-AB-B
55: 100-70-0
45: 0-70-100

In effect, each A supporter agrees to switch his probability to AB in
exchange for a B supporter switching to AB.

So, the initial probabilities would be

A: 55%
AB: 0%
B: 45%

Expected utility
55: 55
45: 45
Total: 100

However, after the negotiation stage, the results might be

A: 10%
AB: 90%
B: 0%

Expected utility

55: 10% of 100 and 90% of 70 = 73
45: 90% of 70 = 63
Total: 136

I don't 100% remember the method (and it could do with a web
description :p ), but that is what it is attempting to do.

The idea is not that it is random.  The idea is that it says "OK, if
you can't all agree on a compromise, then we will pick a winner at
random".

The threat that a random winner will be picked is what allows the
negotiation.  If a majority can just impose its will, then there is no
point in compromising.

Umm ok... But it should not be designed to protect rights less that

Majoritarianism only supports itself so far as majority support will take it.

A majority for instance cannot vote to disenfranchise the other 49%.

There are potential free rider issues with trying to please everyone.
In the case of a system that requires total consensus, it is generally
called the hold out problem.

It can be in everyone's interests (including the hold outs) that
decisions are made with less than total agreement.

Basically, fast decisions are a public good, but obtaining decisions
biased in your favour is a private good.

It depends on how the contracts work.

For example, if candidates could make binding campaign promises, then
you would have a contract, but not vote buying.

Another option is with a PR method and a "program for government".

Once the election has happened, a coalition can be formed from parties
that have more than 50% of the vote.  Because they discuss the
policies of the government as a whole, it allows trading of support
for one policy in exchange for support in another.

You could think of rights as the general public protecting themselves
from their government.  They specify the limits of what their
representatives can do.

Perhaps, with direct democracy, they wouldn't be needed, but some
mechanism for allowing the constitution to be changed slowly is
reasonable.  For example, if someone doesn't vote, they are assumed to
no support an instant change.

That is pretty short term thinking.  I think voting themselves the
money would cause people to leave the country, and or, cause massive
civil disobedience.  Also, since you have to payoff more than 50% of
the society, the amount 'looted' will be pretty small per person.

Right. Democracies assumes a given series of weights for all people's
decisions (usually 0 (children/felons/non-citizens) or 1 (people
eligible to vote)). And proceed to crunch the numbers.
They do this in a way distinct from absolute consensus.

democracy is distinct from consensus? Of course it is! I can win under
any reasonable voting method by pleasing less-than-everyone. In some
methods this need only be a majority, in others it may not be a fixed
amount of support. There is no definitive number of people I must
please to win a Borda election, for instance, the actual number
depends on a wide range of other factors.

by removing belligerence of the majority. I attempted to explain in

This is mostly true for majoritarian methods, the majority being the

At the end of that article, some ways out of the "paradox" are

the underlying prisoners' dilemma. In the voting context where secrecy 
is required, binding contracts can only be reached if they are somehow 
brokered by the method. This is effectively done in FAWRB by giving 
voters the possibility to assert their willingness to cooperate by 
marking compromise options as "approved", and by using these marks in a 
way which removes incentives to cheat.



Majority rule and individual rights are inconsistent.


This is the most important lesson! Unfortunately, "majority rule" seems 
to be almost synonymous for "democracy" for most people (or at least 
most westerners). This makes it very hard for them to see that in fact 
majority rule makes democratic decisions impossible!

Good Morning, Greg

There were several points in your message that caught my attention but, 
to avoid opening too many topics, I will only address one:


re: "This all comes down to the very nature of voting and
 democracy.

 As I have attempted to explain, voting is the exact opposite
 of individual rights ..."

I have not seen that sentiment expressed before.  It is worthy of 
further comment:


The reason voting is the opposite of individual rights is that our 
ability to participate in the political process is limited to approving 
or disapproving choices made by others.  Nothing in our present practice 
allows us to influence the selection of the people or issues for which 
we vote.  That right is reserved to subsets of our society and denied to 
the rest of us.  Thus, our political system is oligarchical, rather than 
democratic, in nature.


Voting under such circumstances violates our natural right to govern 
ourselves.

It's more damaging. A precondition for this sort of behavior is
verifiability. If a politician knew who voted for him and could reward
them, then you would see more policies like that. It happens in real
life. Congressional voting records are public. If it weren't so,
lobbyists wouldn't try.

You are also correct. Individually I do not have to give up much in
order to get money. With everyone thinking this way, the policy would

[EM] Buying Votes

2008-10-21 Thread Greg Nisbet
As I mentioned a thread ago, commodification of voting is dangerous.

In the coming message, I will explain the negative externalities
associated with this.

This all comes down to the very nature of voting and democracy.

As I have attempted to explain, voting is the exact opposite of
individual rights and concensus.

All of you know what democracy does, but let me put it in the context
of commodification.

In every reasonable voting method (remember democracy is distinct from
concensus), it is possible for me to gain power by pleasing some
subset of society (so long as that subset is sufficiently large).

The people whom I must convince to support my decision can be
different than the ones who will bear its cost.

I'll call this the Separation of Recipients. Elections divorce benefit
and cost. Normally, I cannot buy something and defer the cost to
someone else without their consent.

This is always present in any democratic society.

Majority rule and individual rights are inconsistent.

Let me explain why commodification of votes is particularly damning.

The entire system of democracy comes crashing down if some majority
votes itself into autocracy. Thankfully, people are bad at
cooperating. Unless votes are verifiable. Think about it, lobbying
exists because lobbyists can see how Congresspeople vote. Such blatant
absues do not occur at voter-level.

Vote verifiability and hence commodification make it possible for me
to trade someone else's well-being for my own. If I act selfishly, I
vote for whichever action brings me the slightest increase in my
well-being whatever the cost to some external party so long as I can
be compensated for the difficulty of voting and loss of the old
winner. I will vote my pocketbook.

This is not to say that democracy is bad.

It is unstable and inefficient, but also peaceful, prosperous,
utilitarian, and the champion of human rights. It will continue to
work so long as voters can cheat their solicitors.
