‘Thinking Fast and Slow’ – A must read for investors, as well as anyone who has to make decisions

By Edward Strafaci

A colleague suggested that I read Daniel Kahneman’s Thinking, Fast and Slow as a way to explore the wiring of our minds regarding decision making. I was not disappointed. Kahneman is a former Nobel Laureate in Economics. His work is the progeny of other pieces, such as “Freakonomics,” which studies the human psyche and how it makes choices. Kahneman’s current best-selling book centers on the two systems that regulate our thought functions and the way we evaluate our life alternatives.
System one is mainly structured around our intuition. It is reactionary, and an amalgam of our own collective experiences, as well as what is naturally wired in us as human beings. Think of it as the brain’s RAM adjusted for “fight or flight” and modern social convention. System two is a more careful, analytical engine that allows us to give greater thought to our everyday selections. It is described as the system that basically “looks, before it leaps.” It is an arrangement of gray matter that serves as our arbiter, giving finality and concentration to our beliefs. While this may not be the first time an economist or a psychologist has written about such competing methods,Thinking, Fast and Slow serves as a tour de force that delves into the innumerable ways that we choose.
This book is essential reading for anyone, though it is especially salient for the money manager. One of the keys when making financial decisions is to eventually review one’s investments post mortem, so to speak. A work like this explores the different avenues that affect our predilections. For example, Kahneman suggests that we tend to frame our risk set based on factors such as loss aversion, more recent experiences and stereotypes or biases. In one instance, he writes about investors who tend to flock to stocks that have been in the news. He also addresses our insistence on selling “winners” while hanging on to losing investments in the hope of recouping our losses and damaged egos. Ultimately, what Kahneman advocates is a cold, hard look at our own body of work. How much of our success is due to true insight and hard work and how much is luck? After all, as we have already suggested in past articles, an approach that favors securities with real value, or arbitrage possibilities, consistently works in the long run. This discipline requires a certain degree of focused analytics and not the good fortune that trends or momentum rewards. Granted the old saw, “it is better to be lucky than smart” or “you can marry more money in an hour than you can make in a generation,” still apply. Nevertheless, it is still important to rely on a cerebral algorithm that tests assumptions, without prejudice, and adjusts for noise due to presumption.
More fascinating still, is Kahneman’s view that we set many of our choices around our own narrative. A storyline that is based on a plot we continually write for ourselves. In this way, we lend a halo effect to those options that resonate with who we want to be, or what we aspire to. We tend to overweight candidates that are attractive to us, rather than ones that are fundamentally sound. In fact, it clearly reminded me of the central premise behind Michael Lewis’ much acclaimed Moneyball. In Moneyball,baseball’s general managers and scouts preferred ballplayers that had a “pro body,” Players who compiled statistics that qualified them, yet with the additional benefit of looking like Mickey Mantle. Lewis’ protagonist, Oakland A’s general manager Billy Beane, upends this technique by using statistical analysis to choose players when drafting. His legacy is a team that saw relative triumph on a meager payroll while competing with payroll giants like the Yankees. To Kahneman’s credit, he concedes that talent and good looks should never be ignored; however, we must stick to the numbers. I apply this to the latest fascination with certain “black box” theory which has proved time and again to eventually run its course. It seems the Warren Buffets of the world win, where others do not, by considering all aspects of a trade using a strong dose of reality. In essence, that is whatThinking, Fast and Slow endorses, and I find it hard to argue with that line of reasoning.
Kahneman allows for the intangible and non-analytical, and that is what makes him special. He gives discourse on the great benefit of optimism which runs contrary to his thesis. Optimists tend to get over failure much quicker than most and is what makes them valuable entrepreneurs and creators. Optimists sometimes ignore the obvious risks. For instance, it was Edison’s insistence on trial and error that brought us the light bulb. In Thinking, Fast and Slow, we see that reality takes care of the constant concerns while optimism and originality inspire greatness.
It would be too exhaustive to explore all of the circumstances that this tome uses to describe our inner workings. Suffice to say it has been selected for many “must read” lists and justifiably so.
The journey one makes with Kahneman is that of reflection, and a contemplation of our brain’s flow chart. It definitely belongs on every serious investor’s book shelf. It should be read and re-read, and applied to our judgments, both in the financial arena and beyond. Having said that, it is also an entertaining and thought provoking read—and you may learn something, despite your inner tendencies.
