Tacit knowledge is knowledge that cannot be captured by words alone. Cedric Chin, a software developer and career coach, synthesizes research on tacit knowledge over five essays to answer some quintessential career questions — How do I get better at something? How do I master something? Chin criticizes popular discourse around career mentorship and skill acquisition that often manifests in conversations with experts and influencers, but lacks imitation, emulation, apprenticeship, and feedback — or, the actions necessary to learn, understand, and apply new skills meaningfully. Chin (and Plot Twisters) believe that tacit knowledge is missing from modern education.
