I believe this is very significant, so I would like to see this
discussion.  I'll go digging in the archives, unless someone has some
references or summary pages.

If it is agreed by most people that Approval Voting will home in quickly on
the median voter and then stay there, and if we also agree that this is a
good long-term goal, then I believe we should be able to skip most of the
rest of the arguments.

Is there any other voting system that does this?   Or any that does it so
simply and verifiably, with ease and stability?

Why should homing in on the voter median be considered a good goal?
 Simply because the median is the most fair way to represent most of the
people.

Alternatives that result in representing the views of barely half of the
voters at best (with two dominant parties) can be no better than half as
good, and often far worse because of flip-flopping from one election to the
next (so maybe they are all good, but only half the time) with deadlocking
between uncooperative polarizing parties all the rest of the time.  But two
dominating parties are even worse when they both polarize around the
middle, while squeezing out the middle and thus rarely if ever settling on
the middle.   Such a system would seem to be designed around actively
discouraging cooperation.

Alternatives that result in many smaller parties might result in workable
coalitions between multiple parties, but still with substantial
flip-flopping instability and/or deadlocking.   To the extent that the
coalitions work, they will more likely be representative of the median.

Alternatives, such as the above, that discourage extreme positions from
having much voice or representation at all should be concerned about an
accumulation of corruption that comes from repeated applications of
lesser-evil voting.  But homing in on the voter median can also have this
problem, as discussed below.


Here are a couple potential problems with representing the median that I
can think of:

* For some policies, it may not make much sense to compromise on a median
solution, and so a representative of the median might be an indecisive
do-nothing, unable to move one way or another.  But most issues have a
range of solutions and many reasonable ways to compromise.

* Extreme positions held by a small percentage of voters will tend to be
ignored.  This might be considered a good thing, but sometimes, the
extremes are where we need to go.  E.g. 100% renewable energy and 100%
recycling is rather extreme, but I claim it is exactly where we need to be
going as fast as possible.  However, we should find ways to encourage
voters with more convincing extreme positions to express their views and
thus have some impact on the rest of the voters and representatives by
shifting opinions gradually in the direction of those extremes.  Also
possible is that the opposite extremes may have a neutralizing effect,
resulting in almost no motion away from the median.  But is our current
flip-flopping really better than this?

* As a consequence of ignoring extremes over a long time, a government
dominated by the median will tend toward tyranny of the overwhelmingly
"vast majority", if it is not kept in check.  This could potentially
devolve into a mediocracy instead of a meritocracy if we are not careful.
I believe we shouldn't consider the problem as being with the "vast
majority" but with the tyranny that could set in.

I have a plan for avoiding these problems, which in short, involves a House
of Delegates selected in exact proportional representation of the voters,
in addition to the House of Representatives elected by Approval Voting.
More in another message.


In contrast to the potential problems, the advantages of representing the
median are huge:

* A Congress composed of members who each represent the median of the
congressional districts, for Representatives, and whole states, for the
at-large Senators, will still cover a range of positions reflective of each
geographic region.

* It will be much easier to find agreement among members of Congress who
are all closer to the median.  No deadlocking.  No flip-flopping.  And a
President who represents the median of the entire country would be able to
work very effectively which such a Congress.

* Gerrymandering would be quickly obsoleted.  No matter where boundaries
are drawn between congressional districts, and no matter where state
boundaries happen to have been laid permanently, all the voters in a region
will be effectively factored into this median calculation.  There would be
no benefit in arranging that slightly more than half the voters will likely
vote for one party in an attempt to exclude as many of the non-supporters
of that party as possible.  This is because the more likely winner would be
a candidate who is approved of by more people regardless of party
affiliation.  Black and white mixed populations would tend to elect
representatives who are sensitive to the needs of both blacks and whites.

* Parties would tend to be weakened to the point of obsolescence.   This is
mostly because the winning candidates will almost always be close to the
median regardless of party, so everyone would be a member of the one median
party if there were such a thing.  But there are other ways that parties
can be encouraged, and it is important to acknowledge they will tend to
arise even if actively discouraged because we want and need to gather with
like-minded people.   It is not the parties I object to so much as the
disproportionate power they tend to accumulate.  And so I believe we should
always be on guard to strongly discourage any disproportionate
concentration of power under the control of part of the population that is
exclusive of everyone else.

Are people who oppose Approval Voting in disagreement about any of these
advantages of homing in on the median voter?  Or do you disagree that these
are advantages, or that Approval Voting will home in on the median voter?

With a House of Delegates, where each delegate is selected by voters to
best represent their views, we could let the delegates vote on behalf of
the voters, weighted by the number of voters they represent, so there would
be far fewer individual counts to worry about.

A show of hands is a good example of how votes tend to be binary, all or
nothing.  We could show 2 hands, or show a number of fingers for more
fine-grained votes, but I've never seen either done.   A show of hands
could be used for plurality or approval voting since both involve the
simple binary indicators.  Any other voting systems make sense for this?

I can't agree with that.  While a verifiable voting system is essential, it
is not enough, even with the other things.  A verifiable voting system that
essentially helps maintains and rationalize the oligarchy (see, they voted
for us), even with a fair media, etc, is still dominated by the oligarchy,
and is not much of a democracy.  It becomes harder and harder to maintain
the illusion of democracy, but it persists as the minority in power
increases their power.  It may eventually self-correct if it doesn't
self-destruct, but not without huge changes necessary to clean up the
corruption.  That's what we are now up against.

This is a good time to not only ensure we have a verifiable voting system
but one that helps elect fair representatives of the "vast majority" of
people, and other good things.

If parties were only about summarizing their proposals in platforms, that
would be great.  I think that could be a good thing.  But parties have
become much more than that for several reasons.  They will naturally try to
grow as much as they can by including multiple factions with mutually
exclusive disagreements which are then sacrificed for the benefit of the
party.  By defining what a party represents, they are drawing boundaries
around themselves to exclude others, and some positions may not fit in any
dominant party and will be excluded.  So parties can be both over-inclusive
and over-exclusive.  When the voting system strongly encourages very few
parties, such as the two dominant parties of plurality, then the abuses can
grow quickly, concentrating power in those few parties.  They will tend to
impose legal procedures such as primary elections and debate rules that
further exacerbate the problems, becoming self-serving as they suppress all
alternatives.

Forcing all primaries for all parties to be on one ballot per state would
avoid some of the abuses, but not all of them.  Maybe most of the problems
with parties can be addressed in various ways, but I think we need to make
a much bigger leap beyond parties in any usual sense.  We don't need to
think in terms of parties to organize our proposals if we have some better
alternatives.

That sounds good, but it is blurring what is going on among the 99% such
that they might actually acting as one entity, rather than what we have
now, two dominant entities that are set against each other in constant
futile battles over the few scraps thrown at us by the 1%.

How the democracy functions is critical, not just that it appears to be a
democracy, even one that we believe truly represents us.  Even if it really
does start out representing us pretty well, if it grows into a fractured,
divisive, schizophrenic blob ruled by sociopaths, well it didn't work, and
we need to understand why, how it happened, and how we can avoid it.

If the chicken-dilemma only arises in such relatively rare cases, and is
not too severe and is temporary, I am not too worried.  If it means that
non-cooperating older siblings may be usurped by the younger sibling, maybe
that is actually a good thing to shake things up a bit.

I don't seem to care much about the chicken-dilemma, though whether it is a
serious problem probably depends on the voting system.  FBC seems like the
right thing to require, mostly because the consequence of not having FBC is
either two-party dominance, instability, or both.  I don't know enough
about the other voting systems to say for sure, so correct me if that is
over-simplified.

I am asking not about policy goals and how we get there, but the kind of
democracy we want and how we get there.  The extremes I am talking about
here are levels of the hierarchy of government.   At the lowest extreme,
the voting system and how voters make their decisions, and at the highestt
extreme is the resulting characteristics of the representatives of the
people, assuming we have a representative democracy, and how their
decisions reflect the collective will of the people, or whoever they
represent.

Again, I am asking about the nature of the democracy.  Do people want to be
led by a meritocracy, or to be involved in varying degrees with more or
less direct democracy?  Or many other variations.

When we get to how policy decisions are made, rather than how
representatives are elected, we should have the same questions about the
voting system used to make decisions.  This needs to change.

That's the sense of "something wrong" I meant, as opposed to the ideal
voter, like the ideal shopper, who would always vote the "right" way, to
maximize their value. Not only should we recognize that people will
sometimes do the less optimal thing, we should expect it.  And we shouldn't
expect that we can improve things much with sufficient education. Rather,
we should roll with it, and choose a voting system that makes it easier for
the better outcome to best represent the whole of society, assuming that is
the goal.
