Range

by David Epstein

Tiger or Roger?

Tiger Woods was swinging a golf club as a toddler and barely did anything else. Roger Federer tried skiing, wrestling, basketball, football and more, and settled on tennis later than most. David Epstein asks which path suits most people, and argues that it's Roger's.

The key ideas in Range

Kind and wicked worlds

The psychologist Robin Hogarth split learning environments in two. In kind ones, like golf and chess, the rules stay fixed and feedback is quick and accurate. In wicked ones, the rules shift and feedback is slow or misleading. Most of life, and most work, is wicked.

Match quality

Economists call the fit between a person and their work match quality. Ofer Malamud compared students in England and Wales, who picked a subject early, with Scots, who chose later. The early choosers were more likely to switch to unrelated careers afterwards. Sampling first led to better fits.

Drop your tools

Firefighters caught by fast-moving wildfires have died still carrying heavy tools that slowed them down. Letting go felt like giving up who they were. The organisational psychologist Karl Weick saw experts do the same, clinging to familiar methods long after they'd stopped working.

Lines worth underlining

  1. Sampling

    Roger Federer played lots of sports before tennis. Most top athletes sample widely before they specialise.

  2. Kind and wicked

    Narrow practice works in kind worlds like chess. Most of life is wicked, with unclear rules and slow feedback.

  3. Hard learning

    Learning that feels slow and hard, like testing yourself, sticks better than easy review.

  4. Far analogies

    Ideas from distant fields often crack problems that the experts inside a field are stuck on.

  5. Match quality

    Switching paths can be smart. Trying things is how you find work that fits, which Epstein calls match quality.

A story from the book

The Game Boy

Gunpei Yokoi was not a star engineer. At Nintendo he combined cheap, old, well-understood parts in new ways, which he called lateral thinking with withered technology. His Game Boy had a basic monochrome screen and outsold flashier colour rivals.

Hot take · true or myth?

In chess, starting young and drilling hard really does pay off.

See the book's answer

True. Chess is what Epstein calls a kind learning environment, where patterns repeat and feedback is instant. László Polgár trained his three daughters from early childhood, and all became strong players.

One thing to try

Run a small experiment

Pick one field you keep wondering about and try it for a month, with an evening course, a volunteer shift or a small side project. Epstein, borrowing from Herminia Ibarra, says we learn who we are by trying things. Treat it as a test you can walk away from.
