This was one of the most mind-boggling books I’ve ever read, due to its capacity to make the reader rationalize and question its approach to daily decisions, which he/she usually undertakes without much ado and thought.
This book is also very accessible to someone like me, who doesn’t have a mathematical background. This is so because the book reviews the history of knowledge on probabilities, decision-making, uncertainty, and risk without much analytical or graphical resources, focusing instead on examples and case studies.
It’s also quite entertaining, since it contains many references to petit histoires from the great intelectual characters: Archimedes, Aristotle, Arrow, Bayes, Bentham, the Bernoullis, de Méré, Diderot, Fermat (a lawyer), Gauss, Kahneman, Keynes, Knight, Morgenstern, Nash, Quetelet, Smith, Tversky, or von Neumann are a small part of the larger array of brilliant minds whose work Professor Bernstein quotes to assemble this magnificent history of risk.
In fact, and as it can be seen from the quoted listed, the book covers 450 years on the subject of risk from a wide perspective: it is not restricted to risk management or insurance, but it also includes thoughtful reflections on investment, decision-making, game theory, covariances, biases, regression to the mean, etc.
Another impressive feature of this book is its practical reach: for example, the theory surrounding loss-aversion clearly provides an interesting framework to read the recent Portuguese government’s measure to protect mortgage borrowers, thus avoiding the fire sales that would result from borrowers stress-selling their homes. This protection is provided in sacrifice of first-time buyers, who would benefit from prices falling. However, it’s (politically and behaviorally) rational for the government to prefer avoiding current-owners “loosing” their homes than youngsters not being able to buy their first house. Loss-aversion is powerful.
Finally, the chapter on options (“The fantastic system of side bets”) is also a very scholarly but crystal clear lesson on how derivatives work, are priced and what can they be used for. This chapter alone could well make this book a noteworthy study.
A must-read, for sure.
