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?

Yet again, the comments to a previous post have gone on an interesting tangent. Once again Jeff was behind it. He’s not afraid to get stuck into a debate and he always has some interesting points to share, even though I don’t always agree with him! I thought the discussion was quite good so I want to share some of it in a new post and also expand on my thinking behind abstention and why it is not a bad thing.

Before I start I should point out that I have never abstained in an election that was at local government level or above. In fact, in the local government elections last year I listed a whopping four preferences. Not bad for a cynic! (Having said that, it was admittedly for negative reasons — I wanted to vote for everyone except Labour).

Nonetheless, I struggle nowadays to understand why abstainers are so vilified, as though they are sub-human. I think sometimes people conflate abstention with apathy. In reality it is perfectly consistent to be interested in politics and yet not vote when the election comes round.

In his first comment Jeff said:

I find it incredible that someone can maintain such a thoughtful and intelligent political blog with all these numerous opinions and then, when an election comes around, he may not take part.

Compare and contrast with James O’Malley’s comment:

I think your experiences of becoming more apathetic with age – essentially more apathetic as you became better informed – are pretty similar for a lot of people. I’ve just finished a degree in International Relations, and as a consequence of learning what a horrible bleak mess the world is, I think we all became cynical about almost anything political.

I have gone through a similar process. Being interested in elections and voting behaviour, whenever there was an opportunity to study them at university I took it. I wrote my dissertation on what motivates people to vote. The whole learning experience has led me to become less likely to vote and more sympathetic towards abstainers.

(As an aside, if anyone’s interested, I have decided to upload my dissertation here since it got the best mark of anything I ever did at university so I feel quite good about it! So if you’re interested and you have a bit of spare time, have a read and you might get a bit more insight into my current thinking about voting.)

In short, Jeff asked why someone like me would not vote despite knowing so much about politics. What slipped his mind was the possibility that someone like me would not vote because they know so much about politics.

For a few months now I have been meaning to outline a few problems with elections and democracy as we know it (this post isn’t it by the way, it’s still coming). This is not because I am not a democrat, because I am. However, I am disappointed in the poor standard of analysis of democracy. Discussions about it frequently descend into a list of clichés and slogans. It leads me to think that most people are democrats because of blind faith rather than because they have actually thought about it.

That’s a dangerous situation to be in because it breeds complacency. The flaws of democracy are constantly swept under the carpet. But the only way to improve things is to put the flaws on a pedestal and debate them properly. Simply pulling out that hoary old Churchill quote doesn’t bring us any further forward.

That was the case in the comments to the post about student apathy. All I said was that I understood why some people would not vote. Before I knew it, commenters made out that I was advocating something resembling anarchy, I had no right to complain if I didn’t vote, I was doing an injustice to the people of Zimbabwe, and, yes, that bloody Churchill quote was wheeled out. A who’s who of clichéd arguments that get us no further forward.

Bellgrove Belle began proceedings by advocating compulsory voting — albeit with a ‘none of the above’ option (how gracious of you!!). I let that slip by at the time, but only because I didn’t want to go down that tangent. However, now that I have started a separate post I will outline why compulsory voting is the most outrageous idea.

Firstly — and this should hardly need pointing out — people are not the servants of politicians. Yet. Politicians are the servants of the people. Having a government frogmarching everyone to the polling station is not my idea of freedom. The point about the right to vote is that it is a right. That means that you can choose to use it or not. If you are forced to vote, it is no longer a right — it is an oppression.

A vital principle of our liberal way of life is that people know for themselves what is best in almost all instances unless their actions cause harm to others. If people do not vote, it is not because they are wrong (which is a view typically only found among political elites). It is because, for the abstainers, it is costly to go out and vote. And if it is costly for an individual, in turn it is costly to society.

Beyond the cost of sending everyone out to vote, what is wrong with just leaving people be? People should be perfectly entitled to abstain if they want. Forcing people to do things they do not want to do will only breed even more cynicism and apathy.

Having a ‘none of the above’ option is the ridiculous fig leaf to all of these criticisms. There is already a none of the above option. People know very well that they can spoil their paper when they get to the polling station. If people were screaming out for a none of the above option, we would know it by now.

I have only ever heard compulsory voting being advocated by two groups of people: politicians and aspiring politicians. It is funny that these people should select the one ‘solution’ to apathy that is almost guaranteed to give them more votes. What a coincidence! Moreover, it is the lazy option for them to choose. It implies that it is the voters who have done wrong, which is a very undemocratic stance to take in actual fact. For politicians, the idea that it is they themselves who have caused apathy — and that it is their job to fix it — is too difficult for them to comprehend, so it seems.

Jeff was next up, suggesting that the logical conclusion of my defending abstention for an individual is advocating mass abstention. Nothing could be further from the truth. Indeed, it is the very fact that others vote in their millions that makes abstention as an individual a reasonable option.

If no-one else voted then I would find the voting decision very easy — I would cast the deciding vote, probably for myself. We don’t live in that world, and my stance is a pragmatic recognition of that fact.

There is that old guilt trip: “what if everyone else thought like you?” The point is that not everyone does think like me. And it would be rather egotistical of me to think that my actions would be copied en masse by the population as a whole. If it were the case that I was so influential, I would find myself sharing the same bed with six and a half billion others every night. As Stephen Dubner and Steven Levitt point out:

Imagine that you and your 8-year-old daughter are taking a walk through a botanical garden when she suddenly pulls a bright blossom off a tree.

“You shouldn’t do that,” you find yourself saying.

“Why not?” she asks.

“Well,” you reason, “because if everyone picked one, there wouldn’t be any flowers left at all.”

“Yeah, but everybody isn’t picking them,” she says with a look. “Only me.”

Then Jeff pulls out that old one — if you’re so dissatisfied with the candidates, why don’t you stand yourself? The answer, I would have thought, should be obvious. Standing for election would involve immense personal financial and other costs. I would have to give up my job to dedicate enough time to campaigning, meaning a loss of income. Then I would have to somehow fund the campaign itself.

On top of that, I would probably lose my deposit. The political system is heavily biased in favour of the large parties — partly because of the voting system, partly because of the media and whatever else. The fact is that if you want to be successful in an election you almost always need the backing of a big party machine.

Independent candidates are successful from time to time, and small parties do break through. But in reality these are all led by either someone with a lot of money or a celebrity figure like Tommy Sheridan or Martin Bell. The other successful independents are single-issue (often local-issue) candidates, and I am interested in more than one local issue.

The point I am making is that were I to stand for election tomorrow, no matter how good my policies were, I would have almost no chance of making any kind of impact whatsoever. Am I supposed to believe, as Jeff suggests, that this is the extent of my democratic powers? You can’t exactly blame someone for not doing this when the odds are so heavily stacked against them.

Get ready for another cliché now. “If you don’t vote, you don’t have the right to complain.” Aaah, *tick*.

This is one of the oldest ones in the book. Yet even though it’s a catchy slogan, what is always omitted is exactly the reason why you don’t have the right to complain. Is that because there isn’t one?

Democracy is about so much more than elections. For sure, an election is a vital cog in the democratic process, but it is just one cog among many. China has elections, but that doesn’t make it a democracy. Just this week we have witnessed a sham election in Zimbabwe.

I would think that the idea that elections are the only valid form of political participation in a democracy would come as a surprise to the many pressure groups, non-governmental organisations, media outlets, publishers, think tanks, academics, mass demonstrators, lone protesters, letter writers, bloggers even, and others — all of whom play a vital role in a democracy. Is it really more valid to enact change “from within”? Then we are to do away with all of these vital elements of civic society? Are these people all supposed to stand for election as well? Are they harassed about their voting behaviour before being permitted to speak up?

Democracy is so much more than putting an X in a box. It is about speaking out, debating and persuading. If you have next to no power in the ballot box, what is so illegitimate about using a different method of trying to improve the world? I think that suggesting that people don’t have a right to speak out because they recognise that their vote is near worthless is actually an intensely anti-democratic view to take.

Jeff’s position is apparently to say that the only valid way I have to express myself is to vote for someone, even if it is the “least worst” candidate. Am I really supposed to believe that the extent of my democratic rights is to vote Lib Dem instead of Labour?

Even when I do express a preference in the polling booth, that vote is a drop in the ocean. My reasons for voting are lost among those of thousands of other voters (or, in a national election, millions of others), each of whom voted for different reasons. The politician then cherry-picks the reasons that suit his agenda best. So what have I achieved by voting?

I can say that the time I have spent voting is a waste when I could have spent that time engaging in another democratic activity. For instance, I could have spent that time writing here. That way I can articulate my views in an infinitely more nuanced way than I would by voting. This makes my voice louder than it otherwise would have been. I believe that I can make more of a difference by doing this. What would be so illegitimate about that?

This is all without even getting into the instance where you genuinely are undecided. If a voter is guilt-tripped or compelled to haul himself into the polling station, what is he supposed to do? Toss a coin? Close his eyes and see where the pencil lands? Given that your vote is essentially a way of enforcing your views onto other people, I am amazed that anyone thinks that the decision to vote should be taken so lightly.

Finally came the guilt trip from Ideas of Civilisation. He brought up the current situation in Zimbabwe saying, “it’s a reminder of the freedoms, and responsibilities, we have here.”

The thing is, I believe that recent events in Zimbabwe support my view. Morgan Tsvangirai pulled out of the contest because the election was a “violent sham”. Was that illegitimate? Or should he have contested the election because otherwise he doesn’t have the right to criticise? Of course not. His voice is louder outside the contest and he has made the point about the current situation in Zimbabwe very forcefully. It is a perfect example of making one’s voice heard outside of official electoral channels.

Of course, the situation in Zimbabwe is very different to the situation we face in this country and other, freer, more democratic countries. I suspect the point IoC was making about Zimbabwe was that, in such countries whenever there is a free election is usually has a comparatively high turnout.

That is right, although it is a very different situation. When you are given hope in the shape of an inspiring candidate you are bound to grab it with both hands. That is the case even more so if the bandwagon theory (discussed in my dissertation) is true — people want to feel a part of making a big change so will take part in the vote.

You don’t have to live in an unfree country for such a thing to happen, so that doesn’t put this country’s politicians off the hook. Barack Obama is currently doing it in the USA by engaging certain parts of the electorate at levels that have never been achieved before. It’s just that right now there is no such candidate in this country.

Back to the unfree country though. Even in the hypothetical watershed election that brings everyone hope, turnout will not be 100%. It might be higher than the turnouts we see in this country, but it will be nowhere near 100%. In fact, if turnout was anywhere close to 100% accusations of vote rigging will be flying.

This fact demonstrates that abstention is a perfectly natural and legitimate position to take in an election. In fact, it serves a very useful function in a democracy. Any attempts to eradicate it should be viewed with as much suspicion as attempts to eradicate any other political view.

In case you were wondering, this is an even more quiet place than usual just now because I have exams at the moment. Sorry I’ve not been more active at replying to comments in recent weeks. I found the first exam more stressful than I should have, so I decided to take today off to relax. So it’s a good opportunity to stick a lazy post up here.

I’ve been tagged by a meme twice in recent weeks. One of them will be more exciting for you readers, and I have been meaning to write a post like that for about a year anyway. But I will do this one first because the other one will take a bit of preparation. Because I need to preserve all that brain power for the exams.

This is from Angry Steve. I can’t actually see what the common theme that runs through this is. Still, if you have been tagged in a meme and you don’t take part the punishment is fifty lashes in the blogospheric dungeon. So here goes.

1. The rules of the game get posted on the beginning.
2. Each player answers the rules about himself [or indeed herself].
3. At the end of the post, the player tags five people and posts their names, then goes to their blogs and leaves them a comment, letting them know that they’ve been tagged and asking them to read his [or her] blog.

What I was doing ten years ago:

According to my excellent maths skills, I was 12 years old. So I was probably being exceptionally annoying at primary school. I was probably preparing myself mentally for arriving at the big school with all the big bullies.

Five things on my To-Do list today:

Well, I am posting this last thing on Saturday. So here is my to-do list for Sunday.

  1. Watch the GP2 race
  2. Go for a walk round the park
  3. Watch the Spanish Grand Prix
  4. Begin revising for my next exam
  5. Uh, go to bed

Things I would do if I were a billionaire:

Given that I would be financially secure, I would ditch all of my formal commitments and get round to all of those leisure activities that have been building up. The pile of CDs that I bought way back in October and still haven’t had the time to listen to. The DVDs. The books I bought for my summer reading in 2006 and the books that have been added to that pile since. The issues of The Economist which I unwisely purchased a three year subscription to before realising that I didn’t have the time to read a single bloody issue.

Three of my bad habits:

  1. Weighing up the possibilities for so long that the opportunity completely passes by
  2. Eating too quickly
  3. Fingernail biting

Five places I’ve lived:

  1. Glenrothes
  2. Kirkcaldy

Uhh… and that’s it.

Five jobs I’ve had:

  1. Lifting furniture about for an antiques shop run by a family friend
  2. Sales assistant at Woolworths

Uhh… and that’s it.

Five books I’ve recently read:

Hmm difficult one. I don’t often get a chance to read a full book (I think my pace is about two per year). But I have read most of a few books at university so I’ll put the details here.

  1. The Economic Development of Modern Scotland, 1950-1980, Richard Saville (ed.) — Skim-read many chapters for my exam on the Scottish Economy. It’s not very “modern” any more though — it was published in 1985 (no modern perspective on oil, little if anything about electronics, poll tax what poll tax?). Good chapters on the Highlands and Islands Development Agency and the Scottish Development Agency though. Shame they never came up in the exam!
  2. The Myth of the Rational Voter, Bryan Caplan — Food for thought for proponents of “more democracy”. I thought it would be really useful for my dissertation. It was kind of, but I enjoyed the read more for the bits that weren’t much to do with my dissertation.
  3. A Logic of Expressive Choice, Alexander A. Schuessler — A theory on voting behaviour and things like that (cases which should be collective action problems but aren’t). It gets a bit technical towards the end, but the early chapters are fascinating to read. If you want to know why the US President is just like a can of Dr Pepper, this is the book for you!
  4. Freakonomics, Steven D. Levitt & Stephen J. Dubner — Finally something I read in my spare time. Quite fun to read.
  5. The Worldly Philosophers, Robert L. Heilbroner — I found this book very boring; it took me over a year to read. It’s okay when it’s talking about people you’ve heard of. But in the chapters about people I’ve never heard of, it was a real struggle to read.

Five people or communities I’m going to tag:

Well first of all, bollocks to leaving a comment as per rule 3 at the top. It’s bad enough tagging someone as it is. I will tag five people here and if they notice it they can carry on the meme if they wish.

  1. Colin
  2. Jeff
  3. Mat
  4. Rhys
  5. Sarah
