Regular readers of my blog will know that I occasionally like to discuss important constitutional issues. Therefore, today I am going to write about Nikki's
eviction from Big Brother on Friday night.
Many people were surprised that Nikki lost the vote. She had survived a couple of previous public votes and it seemed as though she was going to last until the final week. They have begun to wonder what she had done wrong in her last few days, in order to turn the nation against her. However, I think that this is not the right question to ask. In my opinion, the key to her eviction was the change of voting system. Instead of being up against a single fellow housemate, they had all been put up for eviction, except Jayne, as a punishment for her breaching the Big Brother rules, by discussing the outside world.
To understand why, it is necessary to think about how the housemates are likely to be perceived by the viewing public. Nikki seems to be regarded as irredeemably annoying by a minority, perhaps 20%, but as entertainingly endearing by the rest, say 80%. Now consider Imogen. Of those who have noticed her at all, perhaps 5% think that she at least provides some cute Welsh eye candy while 5% may be frustrated that she is incredibly boring and does nothing at all. The other 90% probably find her so uninteresting that they are completely indifferent to her fate. Indeed, apart from Nikki, and maybe also Pete, I would suggest that this is the profile of most of the housemates, neither loved nor loathed, but in some tedious place in between.
Now, let us put Nikki in a head-to-head eviction battle with any of her rivals. It is plain to see that Nikki would win easily as her fans would flock to vote for her opponent. But put her up against all of them and something odd happens. Now, the minority who dislike her vote her out while the vote of everyone else is split between the eleven others. It is possible that an election candidate who is preferred to every individual rival can be defeated when up against them all. Similarly, if viewers had been asked to vote for their most liked housemate, then I am also highly doubtful that she would have been evicted this week.
Mathematicians have used examples like this to argue that a pure form of democracy is impossible, because the person chosen depends, often quite heavily, upon the electoral system used, and arbitrary factors, such as the number of candidates also affect the outcome. I agree up to a point but I also think that some of the results produced by their models are preferable to others. For example, if you are a television producer, you surely do not want Nikki to be evicted if she is the most watchable person in the house. From Endemol's point of view, the voting system that they introduced was a big mistake.
In real elections, of course, the electorate vote for their favourite rather than their least favourite candidate. Therefore, if a 'first past the post' system is used, with multiple candidates, the result is the opposite of the Big Brother example. In other words, a person who is strongly disliked by a majority, but supported by even quite a small minority, can be elected. Many political theorists have commented on the 'tyranny of the majority' as a possible negative consequence of democracy. However, with a 'first past the post' system in place, a 'tyranny of the minority' becomes perfectly possible.
I find it difficult to regard any system in which a minority can come to power, with a desire to control and oppress the majority, by whom they are hated and feared, as democratic, and this, for me, is the fundamental flaw of the 'first past the post' system. Nor do I regard proportional representation to be the solution. PR can allow often quite unpleasant fringe parties to hold the balance of power, and hence wield disproportionate influence, a fact used by the Nazis to their benefit, and to the world's great cost, in 1930s Germany.
My preferred alternative is some sort of transferable vote system, of which the simplest is the Single Transferable Vote, in which voters are asked to indicate a second choice on their ballot papers. If their preferred candidate is eliminated, their vote passes to this reserve option, with the consequence that the victor must at least not be despised by the majority of the population. A similar system is used in the French presidential election, except that, rather than chooing a second choice, electors vote again in a run-off contest, between the two candidates who poll the most votes in the first election. The advantage of this method was strikingly demonstrated in 2002, when Jean-Marie Le Pen caused a shock by coming second in the initial vote and was then soundly
thrashed by Chirac in the deciding contest.
So there you go. From reality television to mathematics to political theory. I can only hope that, in future parliamentary debates about electoral reform, the benefits of STV will receive more appreciation. Then Nikki will not have been lost to Big Brother in vain.
