Small May Be Ugly, It Is Certainly Less Fragile
Taleb proposes evaluating smallness through fragility, concavity, and response to randomness, rather than relying on the appeal of the phrase small is beautiful.
THE IDEA
SMALL MAY BE UGLY, IT IS CERTAINLY LESS FRAGILE
We often hear the expression “small is beautiful.” It is potent and appealing; many ideas have been offered in its support—almost all of them anecdotal, romantic, or existential. Let us present it within our approach of fragility equals concavity equals dislike of randomness and see how we can measure such an effect.
When to use it
Assessing the resilience of startup companies compared to established firms.
Evaluating the robustness of simple versus complex supply chains.
Comparing how losses change with the size of an investment exposure.
Designing organizational structures that minimize unintended fragilities from scale.
FROM THEORY TO EVERYDAY LIFE
In practice
Small startup vs. large corporation
A startup may have fewer dependencies than a large corporation, yet fewer resources to absorb a loss. To compare fragility, examine how each responds to variation; size alone does not establish the shape of its payoff.
Minimalist investment portfolio
A portfolio with fewer positions is not necessarily less fragile. Compare how its losses change under adverse conditions, including the effects of correlated exposures, rather than using the number of holdings as a measure of robustness.
A MOMENT TO REFLECT
Put it to work.
How does measuring fragility as concavity change the way you evaluate small versus large systems?
Can you identify a situation where a 'small is beautiful' intuition actually hides greater fragility?
What are the practical implications of equating fragility with a dislike of randomness in decision-making?
