there’s no such thing as a fair election 2: Australia’s systems, and the real value of democracy
Canto: So let’s talk about varieties of representative democracy, because I’ve never been clear about them. Looking at the Australian experience, this government website has a summary which starts thus:
The Australian electorate has experienced three types of voting system First Past the Post, Preferential Voting and Proportional Representation (Single Transferable Vote).
The first-past-the-post system hasn’t been used in Australia since the 19th century. All our elections now use forms of preferential and proportional representation voting. Australia, incidentally is one of only three countries in the world that uses preferential voting in major elections. Under full (as opposed to optional) preferential voting, each candidate on the ballot must be given a preference, from first to last. This tends to favour major parties, whose candidates are recognisable, but it can also lead to a local election being won by a candidate with fewer votes than her major opponent.
Jacinta: Yes, this can occur when no candidate gets a majority on the first count. A second count is then held and the candidate with the least votes is excluded. That candidate’s second preferences are distributed amongst the remaining candidates. This may give the second most voted-for candidate the lead, with over 50% of the vote. Or it may put the most-voted-for candidate over the 50% line. Or neither, in which case a third count occurs, until one candidate scores over 50%.
Canto: Yes, as this shows, minor party candidates need to score highly in the first count to have much chance, as second preferences are more often than not directed (by how-to-vote cards, which they may not choose to follow) to the more high-profile major party candidates. This is why minor parties almost never win a seat in the House of Representatives, which, unlike the Senate, uses the preferential voting system. And overall, there can be a problem with this type of voting in single-member electorates, in that one party may win a few seats by large margins, while another wins many seats by a small margin, and so wins more seats while losing the popular vote. That’s of course why governments often engage in pork-barrelling to swing marginal seats.
Jacinta: Some of the concerns raised by full preferential voting can be alleviated somewhat by an optional preferential system, but that brings its own problems which we won’t go into here. Let’s look now at proportional representation, which in the Australian context is described thus on our government website:
Proportional Representation is not a single method of election, for there are a number of variations in use, including the Single Transferable Vote, two variants of which are used in Australia. One is used in Senate elections, and the Hare-Clark version….. is used for elections to the Tasmanian House of Assembly and the ACT Legislative Assembly.
The Senate model for elections is described thus:
Each state and territory acts as a single, multi-member electorate in Senate elections. In half-Senate elections six senators are elected from each state, and two from each territory. In full Senate elections, which follow a dissolution of both houses of the Parliament, 12 senators are elected from each state and two from each territory.
To be elected, a candidate must achieve a quota of votes. Without going into detail, the system provides a greater likelihood of minor parties gaining a Senate seat, and so a greater diversity of voices tends to be heard in that chamber. This also helps the Senate’s function as a ‘house of review’ as the governing party has difficulty in gaining a majority there.
Canto: In ‘Choices’, a chapter of David Deutsch’s book The beginning of infinity, proportional representation is described even more negatively than other options, as it tends to result in watered-down, compromise solutions which end up pleasing nobody and, more importantly, don’t actually solve the problem at hand. But the real issue is broader. We can try to invoke mathematics and social-choice theory to make political systems more representative, but even if this was ‘successful’, which various no-go mathematical theorems show can’t be done, the question arises as to whether the most ‘truly’ representative system will be the fairest and best. As Deutsch points out, all this argy-bargying about voting and representational systems is about input to the system rather than output in the form of good decision-making – the institution of good policy and the removal of bad policy. The creation of pathways to good policy.
Jacinta: Yes, it’s worth quoting what Deutsch, partially channelling Karl Popper, is aiming for here:
The essence of democratic decision-making is not the choice made by the system at elections, but the ideas created between elections. And elections are merely one of the many institutions whose function is to allow such ideas to be created, tested, modified and rejected. The voters are not a fount of wisdom from which the right policies can be empirically ‘derived’. They are attempting, fallibly, to explain the world and thereby to improve it.
Canto: Interesting that Deutsch is careful not to say anything negative about democracy here, but he’s actually underplaying the role of democracy in decision-making, because we all know, I think, that new and important and worthwhile ideas aren’t created by democratic process, but by intellectual elites of one kind or another. These ideas are often carried forward by elected officials who have either helped to create them or have been persuaded by them. It may be that they don’t work or ‘their time hasn’t come’, but if there is a kernel of truth or real benefit to them, as for example with renewable energy and electric vehicles, they will, with modifications and adaptations, succeed in the end.
Jacinta: Yes, and what this sort of progress has to do with democracy is that there really is no political system that nurtures innovation and improvement in the way that democracy does, even if it does so with what sometimes seems frustrating slowness, and with the blockages by vested interests that so often infect politics, democratic or otherwise. Patience, I suppose, is a virtue.
Canto: Yes, democracy is in some ways a politics of persuasion, an invitation to try and discuss and dispute over new ideas, with accepted rules of engagement, trial and error, modification, exchange and respect, grudging or otherwise. And of course, with ongoing elections, it’s also a politics of renewal and revision, and that’s the fairest way of going about things as far as I can see it.
