Western-Style Voting 'A Loser'

sethawoolley writes "In light of the upcoming elections in the US, author William Poundstone was interviewed about voting systems by Mother Jones. In it he advocates the benefits of Range Voting as a solution to Arrow's Impossibility Theorem. Approval, Borda, Instant Runoff, and Condorcet Voting, which are often solutions advocated by the Greens and Libertarians (in the US), are discussed, as well, in light of Warren Smith's recent empirical research using Bayesian Regret. My local party (of which I'm the Parliamentarian) uses Single Transferable voting, but we're considering using Range Voting in the future. One thing is for certain: any system is better than the West's out-dated plurality voting system."

  1. PR-STV in Ireland by zoney_ie · · Score: 5, Interesting

    Here in Ireland we use Proportional Representation with Single Transferable Vote (PR-STV) which is pretty nifty (and apart from anything else, makes election counts a whole lot of fun and a spectator sport that can last for a week).

    The problem however is that no matter what system, we are voting for politicians. Our past election saw the Greens (a small minority party) get into government coalition with the main party here. They've already shown themselves to be well able to play the political game; and I don't mean that as praise.

    The US "two-horse" election style only works (i.e. doesn't lead to social breakdown) because both sides' supporters are reasonably sure that, on average, the supporters of the opposition are not bent on their destruction. In Kenya (or, if you think about it, many countries to which democracy has been exported), citizens do not have this luxury and large-scale elections can have a more polarising effect simply because citizens have more riding on the outcome, I think...

    Correct, there cannot be any perfect system, except in the very limited case of exactly 0, 1, or 2 candidates/parties running. That's sort of the point of the Arrow Impossibility Theorem -- you can game any multi-candidate voting system.

    Preferential voting, range voting, whatever. There will be artifacts that will allow "dishonest" voters to game the system. Even the wikipedia page on Range Voting shows how it could be done with the Kentucky Capitol election example -- Memphis Voters artificially score Nashville low so they they are guaranteed to win the election.

    Our current system is a two-party system, with the system set up with a massive inertia to essentially discourage any 3rd party from running unless they can get a massive momentum from the start, like let's say by being a former president in the case of TR. This is bad. However, two-candidate elections also can't be gamed like preference voting can.

    Note that the primaries, which are not two-candidate elections can be gamed. For example, if I was a Libertarian living in California (a state with no chance of a Republican carrying the state, let alone a Libertarian), I might very well vote for a Democrat in a close primary election, if I think one Democrat (let's say Hillary) would be a disaster, whereas another candidate (Obama) would be less of a disaster (from the point of view of my hypothetical Libertarian sensibilities (which I'm not)).

    But once we're down to two candidates, you can no longer game the system by voting in a specific way.

    Therefore, I think that ranking or preference systems would be fine for *primaries*, but that maintaining a final election between two people is probably a good thing (for this and for the more important reason that we get to focus on the candidates more during the final cycle).

    No it isn't, unless you're being tautological and defining "perfect system" as "one that meets the Arrow Impossibility Theorem criteria". Just reading through the definition of Arrow, IIA didn't seem obviously necessary or correct for a fair/perfect system to me. I then looked at the Wikipedia article and it seems that in fact, altering IIA makes designing a fair voting system possible and that that is what many proposed systems do.

    Essentially, it looks like the point of the Arrow Impossibility Theorem is that "this set of criteria is too simple to accurately model what real-world voting systems are trying to do". It does _not_ say that any sufficiently non-trivial system cannot be fair; it says they cannot meet an arbitrary set of criteria.

    (The whole thing is busted, and strikes me as akin to Econ 101 arguments about people being non-rational; classes often start off talking about utility functions, then switch to dollars for simplification of math, then go on to point out that people aren't rational because they won't bet their $1,000,000 life savings on a 100-to-1 shot at $100,000,001--without recognizing all the lectures they've just gone through about how the marginal value of someone's first dollar is greater than the next and that utility is not actually equal to dollars. No, people don't always behave economically rationally. But them not agreeing with your bogus definitions isn't an example of that)

    My position is that until there is no improvement regarding political ethics you will end up with the same quality of political discussion/decision making that you have today. In short, you have to create a proper set of choices first.

    I really doubt you'd ever get the political parties fixed before you would the voting system. I'd argue that the key benefits of a proportional parliamentary system is that it limits the damage caused by one party over another.

    The problem with Western (I'm assuming American) Winner takes all is that you have 51% of the people literally telling the other 49% what to do without recourse. This gets exorbitantly bad when the same party controls both the Presidency and Congress. In fact, I'll argue that the quality of what the government does (or the fact it isn't doing as much) is when either the congress and presidency is in opposition.

    The only real good solution is to set up the system so that there is always an opposition or some sort of road block and consolation of the people who did not win the election.

    If you have ever studied US history, you will know that during the beginning the Vice President was not appointed or chosen by the winning President but rather was the person who lost but had the most votes. He didn't have veto power, but over all I think it provided some obstacles for a President who wanted to railroad the opposition.

    If we were to really reform in the United States, I would argue that the Vice Presidency go to the looser in the election and he would get veto power. Not an overriding veto though. If the President's party owns the congress and he wants to sign the legislation but the Vice President does not like it, the VP can of course veto it just like the president and congress has to get 2/3rds just like the regular President. However, if the President Vetoes a bill the VP can't unveto it and congress has to do the old 2/3rds method.

    Also, the President and VP can choose their Deputy President and and Deputy VP in case one of them dies or is hospitalized so that the Presidency or Vice Presidency stays within the same party until the next election.

    I suppose the biggest argument against this is that government won't get anything done, and I say that is a good thing because when you setup a situation in which every party must compromise with the other then usually the 49% of the losers aren't going to get railroaded with things they are vehemently against.

    As far as addressing proportional representations, I would argue that we would have to do away with the house of representatives as we know it and do a popular election. If there are a total of 500 seats then you would divide that into 300,000,000 you would get around 600,000 votes per seat. So you could run for a seat in the House and as long as you got 600,000 votes you would be guaranteed a seat. If you got more than that, it wouldn't count. Now of course since all 300 million people don't usually vote, you are going to get plenty of people who didn't get the 600,000 votes to get a seat so you just allow those runner up in the order of highest nation wide votes until you run out of 500 seats.

    That way candidates can run across states so have a more populist view.

    BUT in order to retain the power of the states, I would argue the Senate revert back to its old method of having the senators being elected directly by the state governments or a sort of electoral college for each of the states districts. Now this might seem a step backwards, but in order to balance things out and retain some sort of local constituency of the Senators, they need to be elected by the state or appointed by the State legislators.

    However, there might be better ways to reform the US government, but currently I think its quite broke that we let winners take all do whatever they want while the 49% who voted against the party have little or not say.

    That's why then, in USA you're -allowed- to grow your own marijuana and smoke it all you like -- aslong as you don't, for example, drive while intoxicated. (which would endanger others)

    You're also allowed to drink beer at 18 (again, provided you do it in a way that won't endanger others), walk nude trough town, sell your left kidney, marry your sister provided you get sterilised or are infertile, live in polygamy (or polyandri), or, for that matter, paint your house bright pink.

    Which USA is this again ? Certainly not the one over in North-America, there people regularily get punished for all of these, and a million other crimes which hurt nobody other than possibly themselves. (unless you adopt an extremely silly definition of "hurt")

    All governments aer "nannies" to larger or smaller degree. Overall I'm not convinced the US one is all that much less nannyistic than say the Australian or many European ones.
