Then the outcome would not be the same. It's an interesting distinction, and it might help in answering a question I have about how people respond to this information (more on that below). But here I think you're looking at the effect of knowing (if indeed it is true) that a vote has no effect, whereas I'm looking at the effect of that vote itself. Maybe the easiest way to understand it is in retrospect, by looking at past votes that you cast. I make a statement concerning each of those votes and its actual effect in the objective world. Juho Laatu wrote: > I think it is incorrect or at least misleading to say that > individual votes do not have any influence. They do, as a group. If it had no bearing on the argument, then I might agree it's misleading to say it. But it's actually the premise of the argument. Yesterday I wrote to another correspondent: A more direct answer [how is it possible?] is in the rounding procedure that translates a fine-grained sum into a coarse-grained outcome (who gets into office). In that rounding, the effect of the fine grain is lost. ... Or, we might stand on empirical grounds and state: the measureable effect of an individual vote on the outcome is zero. Which raises another question, "Why are people surprised to learn this?" James's observation that "no-one would ever vote" if they accepted the truth of it might figure into the answer. But I think the fact itself is indisputable, a matter of empirical science. A simple thought experiment will demonstrate this: 1. Take the last election in which you voted, and look at its outcome (P). 2. Subtract your vote from that election. 3. Recalculate the outcome without your vote (Q). 4. Look at the difference between P and Q. 5. Repeat for all the elections you ever participated in. Your vote never made a difference. Most people feel uncomfortable or perplexed in this knowledge, and I think the feeling indicates that something's wrong.

I say that electors are physically separated from their ballots, and I explain why this procedure is necessarily a design flaw. I trace other flaws, faults and failures back to this (including the meaningless vote). But I say nothing about how to deal with the situation. I think we lack an understanding of the overall problem, so I'm just trying to figure it out. > If I am offered options that affect my life, options that I've had > no voice in defining, the ability to choose one of them is neither > free nor democratic.

Yet, I believe this too can be traced to the design flaw in the electoral system. It's surprising a single flaw could propagate so many failures, in such different forms, but it appears to be the case. This draft section (design flaw) dealt only with the flaw itself, and how it renders the results of the election technically invalid. Other sections (not yet drafted) will attempt to uncover the paths by which the design flaw propagates through society at large. -- Michael Allan Toronto, +1 416-699-9528 http://zelea.com/ James Gilmour wrote: > Michael Allan > Sent: Monday, October 03, 2011 9:31 AM > > ABSTRACT > > > > An individual vote has no effect on the formal outcome of the > > election; whether the vote is cast or not, the outcome is the > > same regardless. > > These statements worry me - surely they contain a logical flaw?

Re: [EM] Enhanced DMC
After some private email exchanges with Forest and Chris, I'm proposing a simple way of implementing Enhanced DMC, plus a new name, Strong Approval Round Robin Voting (SARR Voting). Ballot: Ranked Voting, all explicitly ranked candidates considered approved. Equal ranking allowed. I'm basing this on recommendation from Chris Benham. I'm open to alternatives, but it seems to be the easiest way to do it for now, and the most resistant to burying strategies. Tallying: Form the pairwise matrix, using the standard Condorcet procedure. In the diagonal entries, save total Approval votes. For N candidates, the list of candidates in order from highest to lowest approval is X_0, X_1, ..., X_k, X_{k+1}, ..., X_{N-1} Initialize the Strong set to the empty set Initialize the Weak set to the empty set. For k = 0 to N-1, If X_k is already in the Weak set, continue iterating. (X_k is defeated by a higher approved candidate. This is called being "strongly defeated".) If X_k loses to a member of the Weak set, continue iterating. (X_k may defeat all higher approved candidates, but is "weakly defeated" by at least one of them.) If we're still here in the loop, X_k defeats all candidates in the Strong Set and all candidates in the Weak set. (X_k "covers" all previously added members of the Strong set.) Add X_k to the Strong set and add all of X_k's defeats to the Weak set. Set the provisional winner to X_k. The last provisional winner (the last candidate added to the Strong set) is the winner of the election. Note: The first member of the Strong Set will be X_0. It is easiest to do this by hand if you first permute the pairwise array so that it follows the same X_0, ..., X_{N-1} ordering. As an example election, consider the one on this page: http://wiki.electorama.com/wiki/Marginal_Ranked_Approval_Voting Iterating through E, A, C, B, D, we find E: Strong and Weak Sets are empty, so E has no losses to either. Strong set = {E}; Weak set = {C, D} Provisional winner set to E. A: A defeats Strong set {E} and Weak set {C, D}. => Strong set = {E, A}; Weak set = {C, D} Provisional winner set to A. C: in Weak set, not added to Strong set. B: Defeats A, but is defeated by D from Weak set (and is therefore "weakly defeated" by A). D: in Weak set, not added to Strong set. A is the last candidate added to the Strong set, so A wins.

Re: [EM] advocacy: Approval is premature compromise
Of course Approval voting will never be used for electing U.S. Congressmen or state governors. Yet at the opposite end of the "size" spectrum, Approval voting is clearly useful in small groups. At what point in the continuum between high-stakes elections and small-group decisions does Approval voting become inappropriate? We don't know, and we wouldn't agree, so let's let others make that choice. The "elephant in the room" is that advocates of Range voting need to also endorse Approval voting both because one criticism of Range voting is that it can (might?) produce Approval-like results if every voter votes strategically, and because Score ballots have greater appeal if we also promote Approval ballots. I think our role is to educate citizens about alternatives to single-mark ballots, and then let those newly educated citizens choose which method best fits each specific situation. Although I wouldn't want a U.S. President chosen by Approval voting, I would be happy to use Approval voting in a _primary_ election for U.S. President. I agree we should aim high. I think we are already doing that by aiming for a large number of signatures.

Re: [EM] PR approval voting
My system isn't quota based and doesn't involve any reweighting or redistribution. It looks at every possible result (potentially problematic in itself) and works out a score for each one. Because there is no redistribution, a voter can lose out more than some other systems by voting too high for a candidate that is going to get elected anyway. But I would argue that it gives the best proportional results for honest voting, and could still potentially deliver good overall results unless some candidates' supporters are much better at adopting strategy than others. A bit like with single-winner range where you wouldn't expect one particular faction of voters to vote approval style and "ruin" the whole thing.

Since I wrote that, I have come to believe (but still haven't proved) that Approval-based methods will generally pass participation and IIAC. A range based method will pass participation, at least in single-winner, if it doesn't adjust ratings. In many cases my version of Range Transferable Vote will elect winners without having to raise ratings to meet quota. It only fails participation in those cases where the quota is not met, which most often happens on the last or penultimate seat. Is your PRV method quota-based? If so, does it pass Droop proportionality? If so, how do you deal with elevating preferences if no candidate achieves a quota?

Re: [EM] advocacy: Approval is premature compromise
I certainly sympathize with the desire to avoid premature compromise. Brian gave the example of universal healthcare versus the Obama plan. As someone who phonebanked for Obama in 2008 (from Guatemala) but now thinks he's a decidedly worse-than-average president, I agree with your example. But I don't think that the voting reform situation is comparable. With healthcare, it is clear that Obamacare is a compromise; that the more radical option is single payer; and that going further still would take you to single provider. With voting reform, the next step after approval is not so clear. Is it Condorcet, Majority Judgment, SODA, or Range? Any one of us could answer that question; but we cannot agree on a common answer. Also, approval is clearly a step towards any of those other systems. Obamacare is an unholy Frankenstein of ad-hoc adjustments. I am not suggesting that we all redirect all our energies to passing approval. Obviously we are all free to make our own evaluations of where our reform energy is best-spent. I am simply arguing that ... well, if we were voting on voting systems, correct strategy would be to all put our "approval threshold" just below approval.

Re: [EM] A design flaw in the electoral system
Good Morning, James I, too, am not completely clear on Michael's meaning. When a choice is made by counting votes, your notion that each vote has an effect seems intuitively obvious. However, the effectiveness of each vote is less clear. One expression of the problem was written by Daniel R. Ortiz in The Paradox of Mass Democracy: "Democracy's three necessary conditions increasingly and embarrassingly conflict. For perfectly understandable reasons, the more we broaden and equalize political participation, the more difficult we make individual political choice. In other words, there is some tradeoff between the quantity and quality of individual political engagement." p. 211, Rethinking The Vote, Oxford University Press, 2004 Thus, voting in the real world becomes - as Michael says - meaningless. We must look deeper. The most fundamental element of politics is that issues arise in the body politic. Although individuals and groups can instigate issues, they cannot prevent their inception. That is to say, issues are independent of any individual or group; they are a matter of the people. Current political practice allows groups to 'interpret' public issues and offer options for their resolution. Such a process is inherently flawed because the groups that 'interpret' the issues offer options that favor their interest. The result is perpetual confrontation between groups seeking advantages. We can do better than that. Fred Gohlke Election-Methods mailing list - see http://electorama.com/em for list info
Re: [EM] A design flaw in the electoral system
Good Morning, Michael I am not entirely clear on the flow of logic in your abstract, but I get the sense that you're saying voters should be able to cast their vote and have it, too ... Voters are not pieces of cake. The act of voting does not remove their needs and desires from the political system. They should be able to continue to influence the political process after they've voted. If that understanding of your paper is incorrect, I must improve my understanding before I can comment more intelligently. At the risk of digressing, I'd like to suggest that the 'Design Flaw in the Electoral System' is a step further back. The flaw is in the assumption that the right to vote, by itself, makes a system free and democratic. That assumption is the root of the failure of our political system. If I am offered options that affect my life, options that I've had no voice in defining, the ability to choose one of them is neither free nor democratic. On the contrary, it expresses my status as a subject of those who defined the options. The right to vote in such circumstances is a farce. This is not to say voting is unimportant, it is to say that formation of the options on which we vote is more important.
