“So why is it, then, that when it seems obvious that to understand finance you need to understand human behaviour, Finance World continues to insist that finance is `all about numbers’ and can be fully understood using mathematics? Partly, perhaps, because so many of them are mathematicians to start with and they find it difficult to see things other than within a numerical framework. Partly, perhaps also, because many have Type-A personalities and they find it difficult to deal with uncertainty. Yet surely also because so many are reluctant to admit that they may have been wasting their time all these years basing their work on the Markowitz worldview, just as so many unrepentant socialists found it difficult to admit they had been used as Stalin’s `useful idiots’ when the Soviet Union’ collapsed.”
– Guy Fraser-Sampson, The Pillars of Finance: The Misalignment Theory and Investment Practice, page 187. The book is about how, under the influence of mathematics specialists such as Markowitz, a lot of investment decisions got dangerously out of whack with reality, as we saw in 2008. Despite some pushback, a lot of the investment industry on which our pensions and savings depend are in thrall to risk and market ideas that are seriously mistaken. Throw in the joys of central bank fiat money and the rest, you have a problem. I should add that Fraser-Sampson, who is a professional investment figure as well as academic, is a big fan of the Austrian school (von Mises, etc). Even better, Douglas Adams, the 30 Year’s War and The Goon Show make an appearance. What more can one ask for in a book about finance?
