90% of Your Team Thinks They're Elite. The Data Says They're Average. | "Contagious Success" — Stagnation Assassin Book Review

Send us Fan MailOnly ten percent of knowledge workers belong to genuinely high-performing teams. The other ninety percent told researchers they were elite. The data said otherwise. That's not a performance gap — that's a performance delusion, and it's the most expensive lie in corporate America.In this episode, Todd Hagopian breaks down "Contagious Success" by Susan Lucia Annunzio — a research-backed argument built on a global study of over 3,000 workers across 10 countries. Annunzio's central thesis: stop pouring consulting dollars into fixing your worst teams. Instead, find your best-performing workgroups, study what makes them win, and replicate that formula across the organization.Todd gives the book credit for its powerful central insight and serious research base, then delivers the Murder Board: obvious principles, a flawed replication model, and no tactical playbook for the operator who has to make it happen in a messy, political organization.STAGNATION VERDICT: 3 Kills out of 5 — Good ideas.
