One of the most important books for left liberals in recent years has been the “The Spirit Level: Why More Equal Societies Almost Always Do Better“. It’s important for number of reasons, however the main one is that it appears to provide an empirical basis to justify policies that redistribute income for no purpose other than redistribution.
In some Liberal Democrat and Labour circles it has been treated with a sense of uncritical reverence usually reserved for religious tracts.
This is not entirely without reason, it is a good read, and the weight of statistical evidence, both comparisons between countries and between US states, across multiple social trends do seem to point to unarguable case that more equal societies are, on the whole, nicer places to live.
Those then claiming to seek “evidence-based politics” should be pleased by the detailed rebuttal issued by Policy Exchange today - Beware of False Prophets.
The 125 page white paper is also a cracking read and debunks the Spirit Level correlation arguments almost entirely, bar in the one instance of infant mortality, often using their own evidence. A table at the end summarises the problems


The rest of the paper goes through each of the claims in detail and provides comparative analysis, showing what happens when extreme cases are removed (for example the US heavily distorts murder rate correlations, Japan life expectancy).
Clusters of nations that do not explain inequality relationships elsewhere, but might reflect the result of cultural history (Remove Scandinavia and most inequality relationships collapse between the rest).
Highlighting selective use of evidence, such as country choice, and which social statistics they regard as important (they ignore all trends where more equal societies have it worse for example suicide rates, HIV, boozing and divorce).
That socialism encourages suicide does not surprise me, who aspires to be an arbitrary average? But I remain respectful of people’s right to choose the miserable philosophy for themselves. The Spirit Level also ignores rapid improvements in life expectancy in countries where inequality has also been rising.
The Spirit Level does not look a correlations that better explain social trends than income inequality. In their US data for example the uncomfortable conclusion of the counter-analysis is that “the proportion of African-Americans in a state is often a much stronger predictor of social outcomes than the level of income inequality”. True or not, it is a stark warning against using isolated social trend correlations to drive prescriptive policies.
On a smaller note within the same theme, when I had the opportunity to put a question to the author of the Spirit Level at a meeting last year, I asked him whether if his or similarly modelled data showed ‘rich’ countries with less freedom had better social outcomes than those with more freedom, he would advocate policies that reduce freedom. His prickly non-response did not suggest the kind of critical open mind that separates genuinely curious researchers from political activists.
An approach evident in his Equality Trust response to the Policy Exchange paper today, which does little more than reiterate previous points, rather than answer the challenges raised.
Prior to this publication I had thought the main problem with the Spirit Level was that it confuses correlation with causation, and suffers the delusion that very different states can simply be planned into better shape by state action if only we knew the right lever to pull. But this powerful rebuttal also makes clear that the correlations used are highly suspect, selective, and in many cases simply wrong.
As the report notes “Despite the enthusiastic reception this book has received from social commentators, its claims are unsupported. The ethical debate over inequality remains unresolved.”
This is not an argument that inequality doesn’t matter, or conversely that it’s a good thing. It is an argument against the distributionalist position that it is the only thing that matters or automatically more important than other social goods.
It is against the notion that by throwing money at redistribution all other things improve. General social trends it would seem are bad at improving your health for you, you may need to make some effort yourself.
To believe the Spirit Level has ended the left/right distribution/aspiration debate in politics, let alone within liberalism, is a delusion.
