How do you measure "fair"?

OK so we are used to political campaigns, political parties and the media crying foul about one thing or another being “unfair”. You only need to look at the political slogans in this current election to see how important the word “fair” is to campaigning. “A Future Fair for All” cry the Labour Party, “Building a Fairer Britain” echo the Liberal Democrats and from the furthest corner pipes the Green Party with “Fair is Worth Fighting For!”

Now as my regular readers know, I have issues with the idea of fairness – not that I think we should set out to be “unfair” but that life is (as nearly everyone’s mum and dad says at some point) not fair. Some folk seem to be more fortunate, prettier, cleverer, wittier and less prone to saying stupid things when keeping one’s gob shut might be more sensible. But, since ‘fairness’ is so important, I thought I’d ask how we know whether this or that policy is actually making things more fair.

If I play Newmarket with you and clean up all the pennies – is that fair? If we both turn up for an interview and I get the job because the interviewer liked me and not you – is that fair? Is it fair to take something off Fred and give it to Joe because Fred has more of that something? And when Fred’s extra is the result of good fortune (or what we see as good fortune), what then?

Surely (and assuming we can define it) luck is normally distributed? Some people are very, very lucky and some unfortunate folk seem cursed with ill-fortune. Now the latter may be the result of getting on the wrong side of The Gentry but I suspect it more likely just the curse of mathematics – that bastard normal distribution curve again! It seems the only way to make things fairer is to compress the curve – to have fewer fortunates and fewer unfortunates.

Measuring fairness requires us to measure good fortune, to assess luck and to then take action to redress (in part) the negative impact of luck by removing from the lucky that which they have gained as a result of good fortune rather than some other means (hard work, for example). This is plainly nonsense – and perhaps explains why so many advocates of “fairness” reject out of hand any sensible quantitative approach to the assessment of Government policy. That it is seen as “fair” by these advocates is quite enough! We shouldn’t worry whether is really makes for better or happier lives – misery will be fairly distributed!
