『Hidden Potential』要約

In Hidden Potential, organizational psychologist Adam Grant argues that our greatest opportunities for growth lie not in raw talent but in the skills we develop to absorb and apply what we learn. Drawing on research and real-world stories, Grant distinguishes between potential—what people can become—and achievement, contending that character skills such as persistence, prosocial behavior, and the willingness to seek help matter more than innate ability. A central framework is Grant's "scaffolding of skills," illustrated through cases like the world's best bridge players, who rise not by winning early tournaments but by losing often enough to refine their judgment. He contrasts the "tyranny of high expectations" with the value of "imperfectionism," showing how legendary basketball coach John Wooden used detailed, individualized feedback rather than motivational speeches. Grant introduces the concept of "psychological safety" paired with "accountability," and explores how character can be cultivated through what he calls the "family of four"—praising effort, asking questions, encouraging help-seeking, and modeling growth. Using stories like a young chess prodigy from a disadvantaged background and a Spanish-language learner who became a Scrabble champion, Grant makes a practical case that systems—schools, teams, and workplaces—should judge potential, not just past performance. He also argues that leaders should become "givers" who spot hidden potential in others, and that individuals benefit from "borrowing" confidence, rethinking goals, and turning obstacles into advantages. The book closes by suggesting that we should stop asking what someone can do today and start asking what they can become tomorrow, offering a clear argument for how character, not talent, drives long-term success.
