The counterargument to early specialization — and a useful corrective to the practice literature.
Epstein assembles the case that in domains where the rules are stable and feedback is immediate — chess, golf — early narrow practice pays, while in most professional work, where problems are ill-defined, breadth and late specialization do better. The chapter on analogical thinking is the one that stays with practitioners.
It is a work of synthesis rather than original research, and it argues a side. Read it alongside Ericsson rather than instead of him; the honest position is probably that the answer depends on the domain.
The Times Take: The best antidote to development plans that narrow someone too early — and to your own assumption that the specialist is always the safer bet.
