Archive: voting systems

Here it is: that post I’ve been sitting on for upwards of a year. Before I start, I am going to make a few introductory notes about what I do and don’t mean when I call democracy disturbing. I find that all too often debates about this subject are clouded by dogma, which leads to poor thinking and boilerplate arguments.

Before some cheesy person wheels out that Churchill quote about democracy being the worst system apart from all the other systems, yes of course I have heard it. And it is true. I am a democrat because I believe it brings about favourable conditions. For instance, there is the correlation between democratisation and higher GDP per capita. (Whether democracy is cause or effect does not matter. If the value of the higher GDP per capita is greater than the cost of democracy per head — as it almost certainly is — then democracy is a price worth paying.)

Furthermore, I should define more closely what I mean by democracy. Most of the flaws I will point out are actually problems with elections rather than democracy as a whole. Aspects of democracy such as civil liberties, human rights, freedom of speech, the rule of law, due process, and so on and so forth, are of course things that I am deeply supportive of. This will become clear in my first point.

I tackle the issue not from an anti-democratic perspective. Far from it. My problem is with the approach which sees democracy almost like a religion which ought not be questioned — what Bryan Caplan in his book The Myth of the Rational Voter called “democratic fundamentalists”:

Its purest expression is the cliché, attributed to failed 1928 presidential candidate Al Smith, that “All the ills of democracy can be cured by more democracy.” In other words, no matter what happens, the case for democracy remains untouched.

No case should remain untouched. That is why, for me, there is not enough scrutiny placed on democracy. There is a fear of investigating it, because the benefits of democracy are perceived to be so self-evident that anyone who stops to ask what the disadvantages are is instantly regarded as a fool. That must be dangerous. If we agree that the system is imperfect, the only way to improve the situation is to investigate it and have an awareness of what the problems are.

Just as a final point, much of my thinking in this area came about as a result of the research I did for my dissertation, which was about the “paradox of voting“. In case you want to read more about voting behaviour, I have uploaded my dissertation here.

Having got all of the caveats and explanations out of the way, it is time to move on to my five points.

1. Democracy is not guaranteed to uphold freedoms

This is more or less a rehash of The Devil’s Kitchen’s post which I referred to yesterday. Above I said that “aspects such as civil liberties, human rights, freedom of speech, the rule of law, due process” are important. Arguably, these have all taken a battering by recent democratically elected governments.

Wave goodbye to your right to peacefully protest, have a fair trial and take photographs in public. Say hello to ID cards, the database state, endless reams of CCTV footage, mass DNA collection, control orders, detention without charge and extraordinary rendition. Thanks, democracy!

2. Tyranny of the minority

Most people are familiar with the concept of the tyranny of the majority. Thanks to the system of democracy adopted in this country, it doesn’t even take a majority to construct a tyranny. In the 2005 General Election, 9,562,122 people voted for Labour candidates. Assuming a population of 60 million, this translates to around 16% of the population.

The votes of this small percentage of the UK’s citizens has given the Labour Party 55% of the seats in the House of Commons, a majority of 67 seats. What gives the government the right to rule the country with such dominance? Not the people, that’s for sure. Only 16% of the people expressed a preference for the current government. In fact it is the way the system is constructed, and nothing else, which gives Labour its “legitimacy”.

That brings me neatly on to…

3. The system can’t be fixed

Arrow’s Impossibility Theorem states that there can be no voting system which will be able to fulfil a number of desirable criteria:

  • The Pareto principle — if everyone prefers x to y then y should not be elected
  • Anonymity — every voter should be treated equally
  • Neutrality — every candidate should be treated equally
  • Independence of irrelevant alternatives — the ability of x and y to win an election should not be affected by the entrance of a candidate z
  • Transitivity — if x is preferred to y and y is preferred to z then x should be preferred to z

Independence of irrelevant alternatives is the one that riles up proponents of electoral reform the most. Just think of Ralph Nader, or the farcical events of the 2002 French Presidential election. In this case, the voting system is far more important than the voters themselves. The fifth item on the list refers to Condorcet’s paradox, whereby attempts to find a winner of the election leads you on an endless circle.

We can argue among ourselves about which voting system should be adopted. But (and I’m not saying this will necessarily come as a surprise to anyone), you will never find a system that will please everyone. It will be a matter of choosing the least worst option, as every system has a fatal flaw of some kind. For what it’s worth, my preference is Single Transferable Vote — but that’s a matter for a different post in the future.

For more along these lines, read this post about a talk I attended a couple of years ago. It was given by economist Eric Maskin en route to collecting his Nobel Memorial Prize in Economics. He had some very interesting views on electoral reform.

4. An individual vote is almost worthless

If you are concerned with affecting the course of history by having your say on major political issues, going to cast your vote in an election is more or less a complete waste of your time and energy. It is said that you are more likely to be killed on your way to the polling station than to actually cast the deciding vote.

The probability the the outcome of an election will hinge on your vote is minuscule. Even under the fanciful assumption that in a two candidate US Presidential election each other person is likely vote for either candidate with a probability of 0.5, the probability that your vote will be the deciding vote is 0.00006.

Yet the costs of voting are actually rather large. You have to spend time and possibly money learning about each of the candidates and their policies. The time and money spent travelling to the polling booth is not exactly negligible in the context of the minuscule probability of your vote actually meaning a damn thing.

Of course, this doesn’t mean that voting is wrong. People don’t vote because they believe it will affect the outcome. They vote because it makes them feel good. But the fact that you need to resort to non-instrumental incentives in order to justify the act of voting leaves wide open the possibility that people with bad motives (or motives with bad effects) are more likely to vote…

5. Many who do vote base their decision on prejudices

In his very interesting book The Myth of the Rational Voter, Bryan Caplan said that the fact that people vote can be explained by the fact that they like to hold certain political beliefs. Let’s call our voter a sheep. He may hold suboptimal opinions and support policies that would actually make him worse off. This might be due to social pressures, a sense of self-image or whatever. It is, after all, all too common to meet someone who votes Labour just because their dad did.

It is precisely because a person’s vote is so worthless that sheep are encouraged to vote. They like to go and vote because it makes them feel good, reaffirms to themselves their ideological loyalty and so on. But sheep never stop to think if the policies they support would make them worse off. They don’t have to because their vote doesn’t matter anyway. The cost of ideological loyalty is low. Indeed, the benefits of it are enough to outweigh the costs of voting.

Those who hold no strong ideological loyalties, and who may therefore be expected to enter the polling booth ready to judge fairly based on all of the information they have gathered, are actually far less likely to vote. This is because they feel no warm glow from the act of voting for their favoured party.

As such, the traits of voters are the sort of traits you would normally expect to find on a football terrace. They will trudge along to express their tribal feelings, and will keep on doing so even in the driving rain, even if their football team is rubbish and the game is low-quality.

One might say that the political party you support is rubbish and the state of politics just now is low-quality. Who wants to buy a season ticket? Is it not better to leave that sort of behaviour on the football terraces?

Well, I say “final thoughts”, but really I mean “first and only thoughts” because this is the first time I’ve actually managed to find the time and motivation to write about tomorrow’s Glasgow East by-election.

It’s difficult to know what I am hoping for. The party I am most sympathetic towards — the Lib Dems — has a pretty low chance of achieving anything meaningful. And let us face it, the only reason Glasgow East has interested people is because Labour have a chance of losing a safe seat to the SNP.

Watching the SNP and Labour battling for votes in Glasgow East is like watching the two biggest bullies at school trying to win a popularity contest. You don’t want either of them to win, but deep down inside you really like it when one messes it up, even if it gives the other guy an advantage.

It’s been quite fun to see, therefore, both parties messing it up a bit. Labour’s woes have been pretty well documented. The former MP, David Marshall, is involved in a slimy corruption scandal. He pocketed half a mill in office expenses when his office was his house and his office staff was his family — while representing the poorest constituency in the country. Yes, that sort of brass neck would make me feel ill as well!

Then the candidate Labour were going to put up for the by-election turned out also to be very possibly a corrupt bastard as well. And the two people who “stood against” him magically disappeared — presumably because they were never intended to have a chance of actually being Labour’s candidate.

So Margaret Curran was parachuted in. She is actually quite good, though the “fourth choice” jibes are pretty damaging. This also leaves “the Labour Party in the Scottish Parliament” in a bit of a pickle because she was going to be their leader. But that’s a worry for another day.

I said Margaret Curran is quite good. I meant that she comes across well on the telly. But of course since she is a Labour politician she is actually a honking liar. She said she’s lived in the east of Glasgow all her life, when in fact she has lived for years in a fancy house on the south side. And she mistook a 67-year-old Labour Party activist for a 93-year-old World War II hero “who looks not a day past 70, by the way”.

Not that the SNP’s candidate, John Mason, seems to be much better. In fact, he seems like the sort of person your mother warned you about. When asked about his views on an independence referendum, his answer was somewhat creepy.

When you ask someone to marry you, sometimes you have to persist.

Lovely.

John Mason also has a history of anti-English behaviour, demanding that a school remove England flags from a World Cup display. Given that the SNP is supposed to be trying to do away with the perceived anti-English element of the party — and does a good job of it, by and large — I am surprised that the SNP should give someone with these views a platform in an important by-election.

I don’t believe the SNP is an anti-English party per se (though undoubtedly many of its supporters are anti-English). But if they do not put a lid on this element more effectively might it become their Clause IV?

This is becoming a running theme of this blog, but I’ll say it again — you can’t blame people for not wanting to vote. And it looks like turnout will be very low in Glasgow East.

That is not just because the two front-running parties keep on fouling up. It is because of the decades of Labour neglect that have been inflicted on the area. Glasgow East is a part of the world that has been held by Labour since 1922. Yet it is in an utterly terrible shape.

The statistic about life expectancy in Glasgow East being roughly equal to that of the Gaza Strip is untrue. Life expectancy in Gaza is 71.01 years. In one part of the constituency, Calton, life expectancy is as low as 53.9 years. You can expect to live longer in Pyongyang than in Glasgow.

(Update: Bellgrove Belle pointed out in the comments that Calton is actually in the Glasgow Central constituency, not Glasgow East.)

It is staggering that this kind of poverty exists in the UK. And this is a seat that Labour have held for eight and a half decades straight. Labour is the party of the poor? If by that you mean they like there to be lots of poor people, then you are bang on.

You can blame the Conservatives all you want, but the fact is that in the 86 years Labour have represented the area, Labour have been in government for around 40 of them. And of course 11 of those have been the last 11 years. Given that it is such a poor area, you would have thought Labour would be eager to help them out. Given that Glasgow East is such a safe seat, where Labour have one of their most convincing mandates, you would think Labour would be eager and willing to repay their voters.

But no. As Fraser Nelson has shown, Glasgow East is the ultimate example of the utter failure of Labour and its policies.

Of course, it is also a shining example of the problems created by Labour’s best pal, the First Past the Post voting system. It was the very safeness of the seat that enabled Labour in the west of Scotland to become the arrogant, corrupt cesspit it became.

That is why David Marshall has absolutely no data on the voters of Glasgow East. He just didn’t care. It is the voters’ very loyalty that has meant that the Labour government has continued to ignore the area. “Not a marginal seat? Not a swing voter? Not interested.”

Given that these very voters are constantly lied to by the media and various other people that Labour is the only party that can act in the interests of the poor, it is no wonder that apathy is so widespread in Glasgow East. If I thought Labour — the party that’s been in charge since 1922 — was the best hope for change, I’d be pretty glum about it too.

The really depressing thing is that Labour will almost certainly win this election. That is partly because of the lies I’ve described in the above paragraph. Is it a cliché to say that a monkey in a red rosette would win in Glasgow East? That is the only conclusion you can come to when, time and time again, the voters keep on re-electing this bunch of failures that have done absolutely nothing for them. It is accurate to describe these kinds of seats in the west of Scotland as the modern equivalent of rotten boroughs.

As for the idea that Glasgow East’s voters will be confused between Margaret Curran and the SSP’s Frances Curran, thereby losing Labour some votes, I don’t buy that. The voters won’t be looking for the name ‘Curran’ on the ballot slip. They’ll be looking for the word ‘Labour’.

I was quite surprised therefore when at the start of the campaign political pundits based in London were confidently predicting an SNP win. I think they couldn’t imagine Labour winning any election in the kind of climate the Westminster Government finds itself in at the moment. But they didn’t count on the trusty voters of west central Scotland, who continue to vote Labour like a dirty old man who likes a good hard spanking.

It shows how out of touch the political pundits in London are with the rest of the UK. Since then, things have stabilised and received wisdom seems to point towards a Labour win, albeit with a hugely reduced majority.

Even though the SNP seem confident, I don’t see Labour losing. I think the SNP are making a big mistake by confidently predicting an “earthquake“. This will allow Labour to present a narrow majority (the most likely outcome) as a victory for them when it is anything but.

The fact that Labour’s victory is even in doubt is the real sign that Labour have failed. It shows that just now there is not really such a thing as a safe Labour seat. But the SNP have given them the perfect opportunity to bounce back.

What do I want to happen? Like I say, the choice between the SNP and Labour is a choice between shit and shite. I want neither party to win. I certainly want neither party to convincingly win.

As such, I want the result to be an extremely narrow Labour victory (1,000–500 votes or less). This would maximise the pain to both parties — Labour barely clinging on to what was one of their safest seats, while the SNP lose an election they predicted they would win. Fingers crossed!

A few weeks ago I attended a talk by Eric Maskin, who this year was awarded the Nobel Memorial Prize in Economics for having laid the foundations of mechanism design theory.

Eric Maskin seems to be quite an interesting person. He lives in a house that was once occupied by Albert Einstein. I imagine that would make a great pub quiz question. Perhaps even more startlingly, Eric Maskin dresses up as Albert Einstein at Halloween.

Professor Maskin came to Edinburgh en route to Sweden to talk about voting systems, a topic related to mechanism design.

Arrow’s impossibility theorem implies that no voting system is perfect at satisfying a number of desired criteria. These criteria are:

  • The Pareto principle — if everyone prefers x to y then y should not be elected
  • Anonymity — every voter should be treated equally
  • Neutrality — every candidate should be treated equally
  • Independence of irrelevant alternatives — the ability of x and y to win an election should not be affected by the entrance of a candidate z
  • Transitivity — if x is preferred to y and y is preferred to z then x should be preferred to z

That fourth one is probably the one that grates with most proponents of electoral reform. We can reel off instances where independence of irrelevant alternatives has been violated. For instance, had Ralph Nader not run in 2001 then Al Gore would almost certainly have become President of the USA. A fragmented left in France allowed Jean Marie Le Pen to enter the final run-off with Jacques Chirac in 2002, when there was every chance that Lionel Jospin would have won such a face-off.

Interestingly, Eric Maskin thinks that if the SDP / Liberal alliance hadn’t run in 1983, Michael Foot’s Labour party would have won the general election. What a thought!

Just thinking about this sent me under a dark cloud. The design of institutions clearly has a disturbingly massive effect. The voting system is much more important than the voters themselves, particularly when you couple this thought with the paradox of voting.

The system that Eric Maskin concentrated on is Simple Majority Rule. This method has voters submitting rankings of candidates, just as in Single Transferable Vote. Then you take these rankings and use them to compare candidates in a head-to-head scenario, two candidates at a time. By comparing just two candidates at a time, you get rid of the problem with independence of irrelevant alternatives. If one candidate is preferred over another by >50% of the voters, he wins the election.

Well, almost. Unfortunately, this system is susceptible to Condorcet’s paradox. For instance, >50% of voters may prefer Labour to the Conservatives, >50% of voters may prefer the Conservatives to the Liberal Democrats and >50% of voters may prefer the Lib Dems to Labour. In other words, simple majority rule violates the transitivity principle.

The view of Eric Maskin is that to worry about transitivity is too pessimistic. For him, the Condorcet paradox is possible, but highly unlikely. This is because candidates can be lined up on a spectrum from left to right, and voters tend to vote in accordance with these positions.

As such, he suggests that simple majority rule is good as a least-worst voting system as it meets all of the desired criteria apart from transitivity which is unlikely to be violated. No other voting system works this well as often.

Of course, because the possibility of the Condorcet cycle even exists, there must be a tie-breaker. This is probably cause for a whole new debate in itself!

The talk provided some food for thought. For several years now I have been convinced that there needs to be a move away from the First Past the Post system. For the past few years I have been strongly in favour of Single Transferable Vote.

During the talk, one person in the audience specifically asked Eric Maskin about Single Transferable Vote. He said that STV can still violate independence of irrelevant alternatives, and pointed out that a similar system to STV was used in the 2002 French election.

I’m not entirely convinced that STV is all that similar to the run-off system used in French Presidential elections. The main problem with the French Presidential election (and the other examples that have been highlighted), as Proferssor Maskin pointed out, was the fact that voters were unable to rank candidates. Well, voters can rank candidates in STV.

Nevertheless, Condorcet cycle aside, I find the simple majority rule approach quite appealing. Yet we hear very little about it. If you are interested in electoral reform, I would say it is worth looking into a bit.
