I’ll have to buy Mr. Mansharamani a drink or two if I ever meet him at a bar. I’ve considered myself a generalist for nearly a decade, but I’ve at times had difficulty explaining how useful it is to have a broader viewpoint when looking at specific problems.
All Hail the Generalist
…
Approximately 2,700 years ago, the Greek poet Archilochus wrote that “The fox knows many things, but the hedgehog knows one big thing.” Isaiah Berlin’s 1953 essay “The Fox and the Hedgehog” contrasts hedgehogs that “relate everything to a single, central vision” with foxes who “pursue many ends connected…if at all, only in some de facto way.” It’s really a story of specialists vs. generalists.
In the six decades since Berlin’s essay was published, hedgehogs have come to dominate academia, medicine, finance, law, and many other professional domains. Specialists with deep expertise have ruled the roost, climbing to higher and higher positions. To advance in one’s career, it was most efficient to specialize.
For various reasons, though, the specialist era is waning. The future may belong to the generalist. Why’s that? To begin, our highly interconnected and global economy means that seemingly unrelated developments can affect each other. Consider the Miami condo market, which has rebounded quite nicely since 2008 on the back of strong demand from Latin American buyers. But perhaps a slowdown in China, which can take away the “bid” for certain industrial commodities, might adversely affect many of the Latin American extraction-based companies, countries, and economies. How many real estate professionals in Miami are closely watching Chinese economic developments?
Secondly, specialists toil within a singular tradition and apply formulaic solutions to situations that are rarely well-defined. This often results in intellectual acrobatics to justify one’s perspective in the face of conflicting data. Think about Alan Greenspan’s public admission of “finding a flaw” in his worldview. Academics and serious economists were dogmatically dedicated to the efficient market hypothesis — contributing to the inflation of an unprecedented credit bubble between 2001 and 2007.
Finally, there appears to be reasonable and robust data suggesting that generalists are better at navigating uncertainty. Professor Phillip Tetlock conducted a 20+ year study of 284 professional forecasters. He asked them to predict the probability of various occurrences both within and outside of their areas of expertise. Analysis of the 80,000+ forecasts found that experts are less accurate predictors than non-experts in their area of expertise.
Tetlock’s conclusion: when seeking accuracy of predictions, it is better to turn to those like “Berlin’s prototypical fox, those who know many little things, draw from an eclectic array of traditions, and accept ambiguity and contradictions.” Ideological reliance on a single perspective appears detrimental to one’s ability to successfully navigate vague or poorly-defined situations (which are more prevalent today than ever before).
