Theory, Meet Practice
And The Moneyball Method
Because all good systems begin at the beginning, Part I of The Moneyball Method deals with economic philosophy. In particular, the virtues of money, prices, markets and earned profit. To break that down into digestible pieces, the book sets up five choices that seem to conflict but are in fact compatible and complementary.
Known as false dichotomies, they are theory vs. practice, reason vs. emotion, faith vs. force, moral vs. practical, and fact vs. value. This brief essay will highlight theory vs. practice.
Theory
“Sounds good in theory” is a commonly used phrase, but like most bromides, it needs to be examined. If a proposition “sounds good” but has not worked in practice, then something is wrong with the theory or something is flawed in the knowledge of the audience. In economics, “sounds good in theory” is usually assigned to collectivist schemes like socialism and communism. But you never hear “sounds good in theory” applied to capitalism or fascism.
Therein lies the rub: fascism is a collectivist scheme. And like its cousins, socialism and communism, it forces a duty upon the individual to contribute their talent and energy to “the common good.”
Yet, in the social context of Western culture today, fascism has been assigned to the same category as capitalism – right wing oppression. Why? In order to condemn capitalism without any knowledge or understanding of it. Why? Because capitalism is individualistic – as in the preface to America’s Declaration of Independence.
Practice
To understand how collectivist philosophy has inserted itself into the world of investment management, one place to start is behavioral finance. According to the Mason School of Business at the College of William and Mary, “It's an economic theory that explains often irrational financial behavior, such as overspending on credit cards or panic selling during a market downturn.”
As a byproduct of “behaviorism” in psychology, it presumes that people make decisions according to emotions that are pre-determined by their biology and culture.
To remedy the situation, the investment industry created risk tolerance questionnaires to assist clients with strategy decisions to avoid irrational behavior during extreme markets. The problem is, there is no such thing as “risk tolerance” in isolated circumstances. Without the context of financial assets, cash flow, personal obligations, aspirational goals, age and health – or risk capacity, then “sounds good in theory” propositions are nothing but false premises.
Moneyball
Other theories are inefficient markets, maximum diversification, reversion to the mean and externalities. Those lead to economic analysis, custom portfolios, tactical rebalancing and stakeholder capitalism. Sounds good, right?
In contrast, The Moneyball Method is grounded in solid principles that are proven by the achievement of each investor’s rationally chosen values. And to further prove this theory, the next essay will address the reason vs. emotion dichotomy.

I use this colloquial phrase “sounds good in theory” because often we don’t have all the facts. We either can’t measure them or the thing that we’re measuring varies over time, often (not always) in a Gaussian distribution. So we need systems that are robust against all the tolerances (variances in values) working out against you and making Gertie gallop. Setting aside the moral issue of central planners using force to tell people what to produce, maybe central planning could work if the planners had access to all the information. This is a moot point because there is no substitute for free people producing what works for them.
Regarding irrational market behavior, I know it’s real. I don’t understand how people use its existence as an argument for central planning. Central planners are subject to irrationality and other human foibles just as market participants are.
My saying “sounds good in theory” makes other Ayn Rand fans howl, but my reading of Rand is 180 degrees opposite from that of her most vocal fans.
