the culture code -- leaderbox
Excerpt from Daniel Coyle’s The Culture Code (LeaderBox PDF). Presents experiments and anecdotes showing that team culture — especially interpersonal safety — drives superior group performance more than individual skill. Highlights a kindergarten experiment where cooperative behaviors (risk-taking, quick help, shared problem spotting) produce better outcomes; an anecdote where one member (Jonathan) neutralizes a disruptive person and creates psychological safety; and a cited Harvard finding that strong culture increased net income by 756% over eleven years across ~200+ companies. Emphasizes: culture is enacted through small behaviors, safety is the foundational skill for strong cultures.
