Under our current voting system, voting for the candidate who represents the party you wan in government is not necessarily a smart way to vote. In some cases, choosing the party you want in government is throwing you vote away on a party that is very unlikely to win in your constituency. For instance in the constituency that I live in – Portsmouth South – anyone who votes Labour is pretty much throwing their vote away. The effective choices are between Liberal, or Conservative candidates.

With a transferable vote system (which of course we do not have), a Labour supporter (which isn’t me!) may well vote Labour as their first choice, and Liberal as their second choice to reduce the possibility that the Conservative candidate would win. Similarly, a Tory supporter in Scotland may choose Liberal as their second choice to reduce the chance of a Labour candidate winning.

Under our current system, it is probably better to choose between the two (or rarely three) leading candidates, picking the one that you least dislike the least. Whilst it may go against the grain to vote for somebody other than your preferred candidate, it does mean that your vote against the candidate you dislike the least is more effective.

Smart tactical voting is more complex than this of course – it involves checking the details of your constituency (you may also want to check the Voting Power details for your constituency, and the relevant Wikipedia article), and working out from the previous election results which two (or three if the third is within about 5% of the second placed candidate) and working out which one you would least dislike.

The Tories are warning that a vote for the Liberal party is voting to keep Gordon Brown in power – which is effectively saying that smart voting can accomplish something, but obviously slanted towards favouring voting Tory wherever you are. Whilst no party will encourage tactical voting, it can be for the benefit of whatever party you would prefer.

Vote tactically – it’s the smart thing to do!

Gordon Brown has announced plans to reform the electoral system in the UK after the election – if Labour is elected, and they do not change their minds. Of course they look likely to give us one choice of reform – choose Labour’s preferred option or no reform. What kind of choice is that ?

We should be telling Parliament what kind of electoral reform we want and not just calmly expect what suits the government of the day. If you look at what Gordon Brown is proposing, it probably represents the minimum possible change to our present system. The Alternative Vote (what GB is suggesting) consists of people voting by listing their preferred candidates in order of preference; if there is no overall majority, the candidate with the fewest votes is excluded and the votes of those who voted for him or her are shared out amongst the other candidates according to their second preference.

The idea is that no MP is elected without representing the majority view of his or her constituency. Ok, sounds better than the current system, but is it as good as one of the following :-

Or even the zillions of other possibilities out there – Wikipedia has a good selection.

There are certain advantages to Gordon Brown’s preferred system – it is a relatively small change and does make things a bit fairer. I would myself prefer a more radical change, but I am quite willing to let the people decide and not have our choice restricted to a simple yes or no to choose some politician’s choice. After all, how sure are we that this is actually best for us and not best for the Labour party ?

Of course as you might expect, the Tories are against any form of electoral reform, and the Liberals are in favour (although this isn’t their preferred system).

What I would like to see is a referendum giving us a proper choice amongst a range of options. That would be complicated to difficult to do properly and would be more complex for us people to decide – we would have to spend some time thinking about what we want. We would need a neutral group reviewing possible systems and keeping the list of options down to sensible numbers. We would also need a neutral group coming up with a list of advantages and disadvantages for each, and ideally stop the politicians from making recommendations (asking a politician to keep quiet is wildly unrealistic I know).

The key thing is that we should be making the choice and not the politicians.

It always good to see statisticians give a good hard kick to those who put the word “lies” into the saying “lies, damm lies, and statistics” … the politicians. In this particular case the Conservative Shadow Home Secretary Chris Grayling has been making comparisons between violent crime statistics from the 1990s and the year 2008/9 using the police recorded crimes statistics. The UK Statistics Authority has said (unfortunately it is a PDF document) something more or less along the lines of “you can’t do that” (in an astonished and shocked tone of voice).

According to the UK Statistics Authority, the method for recording crime statistics in police stations was standardised in 2002/3 leading to a marked increase in recorded crime that year due to the change. Indeed they point out that all published statistics on police recorded crime clearly emphasise the fact that the figures cannot be naively compared with values before 2002/3. The statisticians claim that crime figures should be obtained from the British Crime Survey.

The UK Statistics Authority is worried about politicians using statistics to mislead the public and discredit official statistics.

How does Chris respond ? Basically by saying that he doesn’t believe the BCS and that the increase in reported crimes are too big to be explained away by changes in the recording method.

Who would I rather believe ? Who would you rather believe ? A politician ? Or a statistician ? No contest really; statisticians may not have the best reputation, but at least they do not inspire the same level of disgust as a paedophile like politicians do.

The interesting thing is that people believe that violent crime has gotten worse over the last decade. As to why they believe this I don’t know, because from personal experience I can tell you that violent crime has decreased dramatically over the last decade. Back in the day, I used to be off down town most Saturday nights (and often Fridays too), and almost every night out there would be some sort of fracas varying from a bit of a scuffle in a pub, to an all out street brawl with police helmets flying. These days ? I tend to stay home a great deal more, and there is almost no violence that I can see around.

The whole reason for statistical surveys is to go beyond personal experience and belief, to get much closer to the truth. And when you have that statistical survey you do not throw it away because you do not like the results. You have to change your beliefs. Ordinary people can be forgiven for not doing so, but a politician in the position of Shadow Home Secretary has a responsibility to do his or her best for the country.

Let us examine the “lie” accusation a little closer. Using statistical data in an inappropriate manner such as comparing reported crime figures whose recording methodology was different, is just as much a lie as a school child yelling out “You smell”. It also helps to discredit statistics as a whole, because the public is given the impression that one set of statistics says one thing and another says another – which is not the case at all.

Hard for a Tory whose lies are told in the undoubtedly unselfish goal of removing the present Labour government.

So an interim report on the expenses scandal is out and it is suggested that many MPs will have to pay back some of the expenses they have claimed over the last 5 years. And of course we have MPs claiming that it is not fair that they have to pay back expenses that were legitimately claimed under the rules that were set at the time.

No it isn’t fair.

It isn’t fair that MPs had such a lax expenses system that they could claim such ridiculous amounts on ridiculous items.

Complaining about paying back some of the excess is foolish in the extreme – whilst it may not be fair, everyone other than an MP is going to see this as just typical corrupt politician behaviour. Still it should make the next election interesting – we may not have a majority of Labour or Conservative MPs. There will be too many independents 🙂
