Archive: paradox of voting

There is something about the way that economists think that makes them different. Sometimes this makes them downright brilliant. Other times it makes them complete outcasts.

I often enthuse about the paradox of voting — the phenomenon whereby economists struggle to explain why people vote. But when I talk about it to anyone else, the idea is normally met with a combination of confusion and mirth.

I escaped early though. Realising early on that I didn’t really have a talent for economics, I switched tracks soon after completing my degree. I still retain an interest in the subject though, and it definitely still affects the way I think.

The core problem that economics is concerned with is the allocation of scarce resources. Poor John Stuart Mill was traumatised by the problem. When trying to take his mind off the dismal issue, he turned to music. But he only found himself worrying about the scarcity of different musical notes. This insight in turn led him to conclude that, one day in the future, every possible combination of notes will be exhausted and there will be no new melodies.

He needn’t have worried. As we all know in these vuvuzela-aware times, millions will happily make do with one solitary hooting B♭.

A thought about scarcity suddenly struck me today. It is widely thought that this generation will be vilified, but most assume that it will be because we’ve used up all the oil or something.

But what about those all-important usernames on that we depend upon as our identities on the internet? Everyone who has tried to sign up for a half-decent email address knows that it can be a complete pain finding a unique username that isn’t idiotic.

That is how I ended up with an idiotic moniker like ‘doctorvee’. Even this mad username was already taken up on YouTube and Skype when I tried to sign up to those sites. Moreover, some other chappie has decided to call himself ‘Mr DeeJay Doctor V€€’, thereby putting paid to my chance of buying doctorvee.com, should I ever have felt the urge to do so.

The problem is bad enough today. Maybe we can keep on signing up to Twitter with vaguely comprehensible usernames for a few years more. But what about 10, 50, 100 years in the future? Surely by then everything will be used up.

Or perhaps, like Mill and his music, it is just the paranoia that comes with the territory when you think like an economist.

If, like me, you have a reputation among your friends for being particularly knowledgeable about politics, you probably find that when election time comes they turn to you for advice on how to vote. But while I may have more interest and knowledge in politics than some of my friends, I am not really the sort of person to tell people how they should vote.

Although I make it known that my sympathies lie with the Liberal Democrats (as the latest addition to the sidebar indicates), I don’t push it far. At the end of the day it’s a personal decision that should not be made for someone else.

As such, my friends possibly did not get as much guidance as they were expecting. But they were probably more surprised that I sometimes suggested that they perhaps shouldn’t vote.

I may well offer that sort of advice no matter what seat I was speaking in, but it is particularly well-suited to my constituency of Kirkcaldy and Cowdenbeath. The incumbent here is Gordon Brown. In the 2005 election, he got 58% of the votes, and you would imagine even in the worst case scenario for Labour it is about as safe as seats get. According to the Voter Power Index, the average voter in Kirkcaldy and Cowdenbeath has “the equivalent of 0.009 votes”.

That is one of the reasons why I am actively involved in the Liberal Democrat campaign in neighbouring Dunfermline and West Fife, where the contest is much closer. I have a much greater chance of affecting the outcome there than by casting my vote here.

The statistic that I love to tell my friends is that you are more likely to be killed on your way to the polling station than you are to cast the deciding vote. Bringing up the idea of abstaining is certainly a good excuse to wheel out my dissertation, and I have recommended to some of my friends that they should read it! For one thing, by reading it you can find out the morbid statistic, find out the meaning of ‘rational irrationality’ and more.

I am still madly proud of my dissertation — partly because I find the subject so fascinating. Why do people vote when it is apparently against their interests to do so? If you happen to fancy a read of it, it’s available to download — although I should warn you that it’s all in economics-speak!

I have previously written about the notion that abstaining might be the good option, contrary to received wisdom. The idea has not always been welcomed!

A meetup of bloggers is planned for next week in Edinburgh.

Having looked at the initial round of feedback, I have decided that two dates in particular stand out as the most suitable: 25 or 27 August. Alternative possibilities are 26 or 28 August. Personally, I am erring towards 25 August, but if more people can come on one of the other dates we can go with that.

So that I can get a sense of everyone’s availability, I have set up a poll so that people who are thinking of attending can let us know which dates suit best. We will probably go with the date that has the most votes.

I know, I know. Voting is often a pointless activity. But may I remind you that it is your civic duty to vote. Plus, with the relatively small numbers that will be attending I can assure you that your p will be relatively large.

We are also thinking about going to see a show at the Fringe as part of the meetup. This may not be to everyone’s taste — some might prefer to chat and do meetup-type stuff.

Jeff has suggested NewsRevue, which starts at 6pm at the Pleasance Courtyard. Stephen has suggested About the Scots which is at 8pm at the Beehive Inn on the Grassmarket.

Personally, I am erring towards NewsRevue because it might end up being cheaper (Jeff says he might be able to get half price tickets). Also, the earlier start time means that people can avoid it more easily if they wish by just popping along a bit later, and it leaves more time for chat after the show has finished.

If you would rather not go to see a show though, I have included that as an option on the poll too.

Of course, the choice of show almost makes our choice of venue for us, so I will wait until we have settled on an answer before we finalise those plans.

I will take the poll results as they stand at noon on Friday which gives you about two days to vote, while giving people plenty of time to plan ahead for the meetup if they need to.

Thanks!

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?

I wrote my dissertation about the paradox of voting, which is the problem that rational choice theorists have in explaining why people vote. You are more likely to be killed on the way to the polling station than affect the result once you’re inside it — so why vote? The puzzle interested me as soon as I heard of it and I still often think about it.

The answer is that people take into account not just the instrumental benefits of voting. They also take into account a variety of factors that can be loosely gathered under the umbrella term of “civic duty”. The benefits that people get from performing their civic duty outweigh the costs of voting.

But what about people who clearly go way beyond the call of civic duty? This guy travelled 600 miles just to vote in the US Presidential election (via Bernard Salmon).

That is a puzzle to me. But it is clear that this election is enthusing people to an extent that may never have been seen before. Barack Obama in particular is said to have engaged young people and black people in the US political process like never before. Early voting numbers are reported to be high. And now a person whose family has voted Republican for three generations has driven 600 miles to vote for Barack Obama.

It’s worth remembering that it’s not just Obama that is creating this extra interest. I heard a woman on the radio a few days ago saying that she will be voting for the first time in her life — for John McCain. She doesn’t trust Obama because of his inexperience.

It looks like the USA sees itself as being at an important cross-roads, for a whole host of reasons. They want to get this decision right.
