David Epstein's book, "Range," argue against the prevailing belief that early and intense specialization is the key to success. Epstein uses examples from various fields, including sports, music, science, and business, to demonstrate that breadth of experience and knowledge, along with a willingness to embrace ambiguity and change directions, can often lead to greater success in the long run. The author highlights individuals and groups who defied conventional wisdom by adopting a more generalist approach, which enabled them to make breakthroughs and achieve unexpected outcomes. He criticizes the tendency towards hyper-specialization, arguing that it can lead to cognitive entrenchment, limiting creativity and problem-solving abilities. Instead, Epstein advocates for "range" – the ability to connect knowledge and skills across disciplines and contexts – as a valuable asset in a rapidly changing world.
