David Epstein

Author of Range, the book arguing that breadth and analogical reasoning across domains beats early hyperspecialization. Across Kyle’s notes, Epstein’s central thesis is that experience breeds skill only in “kind” learning environments, while in “wicked” domains — where patterns don’t repeat and feedback is delayed — generalists who sample broadly and transfer across fields outperform narrow specialists. The book draws on Daniel Kahneman’s heuristics-and-biases view of expert judgment, Tetlock’s foxes-vs-hedgehogs Forecasting work, and figures like Charles Darwin as models of actively open-minded thinking (see Expertise, Multidisciplinary Thinking, Polymath).

Context: David Epstein is an American science writer and former Sports Illustrated journalist, author of The Sports Gene (2013) and Range (2019).
