Multidisciplinary mental models

From Charlie Munger: “You’ve got to have models in your head. And you’ve got to array your experience—both vicarious and direct—on this latticework of models. You may have noticed students who just try to remember and pound back what is remembered. Well, they fail in school and in life. You’ve got to hang experience on a latticework of models in your head.

I had an early and extreme multidisciplinary cast of mind. I couldn’t stand reaching for a small idea in my own discipline when there was a big idea right over the fence in somebody else’s discipline. So I just grabbed in all directions for the big ideas that would really work.”

That is solid advice and provides a good framework for one’s personal education.

Seth Klarman on anti-fragility

Accepting that we cannot predict the future – i.e., that there will always be unexpected and highly consequential events – is the first step in becoming less fragile and more adaptable. People should be highly skeptical of anyone’s, including their own, ability to predict the future, and instead pursue strategies that can survive whatever may occur. Taleb advises us to be “antifragile”– i.e., to embrace those elements that benefit from volatility, variability, stress, and disorder. This is exactly what we strive to do at Baupost, and Taleb has coined a name for it. The world will always deliver surprises coming from left field, things that have never happened before or, at least, that no one can remember having happened. As Nobel Laureate Daniel Kahneman notes, people tend to underestimate the odds of extreme events that haven’t occurred recently. It’s a tendency known as availability bias. This tendency is crucial to effectively position ourselves to survive and even thrive regardless of an uncertain future. How do we do that? By eschewing portfolio leverage, keeping ample cash balances ready for rapid deployment, pursuing a mostly generalist and flexible approach while avoiding narrow silos, seeking bargain-priced investments where possible adverse developments are already priced in, holding numerous investments with uncorrelated catalysts to drive outcomes irrespective of market levels, maintaining prudent diversification, demanding high intellectual honesty while consistently striving to improve, and having clients whose long-term orientation matches our own.

In the financial markets, there is rarely anything new under the sun, but you can never say you’ve seen it all, and what you thought you would never see can clobber you.

We make no heroic assumptions in our analysis, hoping, instead, that by compounding multiple conservative assumptions, we will create such a substantial margin-of-safety that a lot can go wrong without impairing our capital much or even at all. We never invest just to invest and don’t bet blindly on mean reversion or on historical relationships holding up. Our settings are permanently turned to “risk-off”.

Snowball

Warren Buffett: “The snowball just happens if you’re in the right kind of snow, and that’s what happened with me. I don’t just mean compounding money either. It’s in terms of understanding the world and what kind of friends you accumulate. You get to select over time, and you’ve got to be your own wet snow, in effect. You’d better be picking up snow as you go along, because you’re not going to be getting back up to the top of the hill again. That’s the way life works.

Prelude

Investing requires us to think of the future. But stock markets are a complex adaptive system. This combined with our limited understanding of current and past events makes predicting the future not just hard but plain impossible most times. Thus it is important to understand the limits and limitations of forecasts. But successful investing does not always depend on accurate forecasting particularly when there is an asymmetric return potential versus the capital at risk. This leads to an investment strategy that aims to be anti-fragile – it can survive and do well no matter which future outcome unfolds. It is also important to understand the sources of fragility as we attempt to eliminate them. This is a journal to record my search for asymmetry and anti-fragility through my investment experience.
