Behavioual economics case study
on 5 December 2012
Moneyball is ostensibly a book about Baseball, superfIcially a book about the Oakland A's (equivalent of Bolton Wanderers under Sam Allardyce) and their General Manager (equivalent of a 'Director of football') Billy Beane in the late 90's/early Noughties and how a club with scarce financial resources consistently out-performed its more wealthy rivals and it is! But it is so much more than that, this book has more layers than an onion.
On one level this is a book about Baseball and a maverick who subverted the consensus view on how the game should be played and understood but on a deeper level this is a case study of an idea. It is behavioural economics as applied to sport.
The book demonstrates how Billy Beane used the insights of a Baseball statistician named Bill James (a cipher for Nobel winning behavioural economist Daniel Kahneman, author of 'Thinking, Fast and Slow'?) and the practical mathematical genius of Paul Podesta (a Harvard graduate with no Baseball experience) to outsmart his competitors.
'Reason, even science, was what Billy Beane was intent on bringing to Baseball...... Paul wanted to look at stats because the stats offered offered him new ways of understanding.....That was James's most general point: the naked eye was an inadequate tool for learning what you needed to know to evaluate baseball players and baseball games.'
On one level level this is an old-fashioned David vs Goliath story but on a deeper level it is a book about two competing views of human nature. The view being triumphed in this book is that of 'behavioural economics.' In short, that human beings are inherently irrational. Trusting one's gut, or intuition, is inherently flawed and is subject to systematic biases/limitations/flaws/illusions which can only be rooted out by a sophisticated analysis of relevant statistical data.
The author Michael Lewis is really an economics writer and what he has managed to do is something that many writers (including Daniel Kahneman, whose writings in my opinion tend to be turgid in the extreme) seem unable to do, and that is:- make seemingly complex ideas come alive by embedding them in real-life situations with real people. Moneyball is a great sports book but it is also popular social science writing at its finest too.
