Why this book
Kohn's target is one of the most unquestioned assumptions in parenting, teaching, and management: that dangling a reward in front of someone is the reliable way to get better behavior or better work out of them. He marshals a large body of experimental research to argue the opposite is usually true — when people are rewarded for doing something, they tend to lose interest in the activity itself once the reward is removed, and the quality of their work while chasing the reward is often measurably worse than the work of people given no reward at all, especially on tasks requiring any creativity or genuine problem-solving. His explanation is that a reward reframes the task: instead of doing something because it's interesting or worthwhile, the person starts doing it for the reward, and once that shift happens, the reward becomes the whole point, at the cost of the deeper engagement that produced quality in the first place.
Kohn extends this argument across three domains where reward systems are treated as obviously sensible — classrooms (grades, gold stars, praise contingent on performance), workplaces (bonuses, merit pay, employee-of-the-month plaques), and homes (allowances tied to chores, treats for good behavior) — and argues the same mechanism undermines all three, because rewards and punishments are, at bottom, the same tool: both are forms of control exercised by someone with power over someone without it, and control of that kind reliably produces short-term compliance at the cost of long-term interest, creativity, and even ethical judgment. His alternative isn't the absence of any structure, but what he calls the three C's — content that's genuinely worth learning or doing, meaningful choice over how it's pursued, and collaboration with others rather than isolated competition for a scarce prize — conditions he argues actually sustain motivation because they don't require constant external management to keep working.
Who should read it
Teachers questioning the point of grades and gold stars, managers skeptical of bonus-driven incentive plans, and parents wondering whether paying for chores or grades is quietly backfiring will find a rigorously argued case here, not just a contrarian hunch. It will frustrate readers who want a simple behavioral toolkit to apply tomorrow, since Kohn's proposed alternative demands a genuine redesign of how tasks and relationships are structured, and it will unsettle anyone who has built a management or parenting style around incentive systems they now have to defend against real evidence rather than intuition alone.
About the author
Alfie Kohn is an American author and lecturer on education, parenting, and human behavior, born in 1957 in Miami Beach. He earned a bachelor's degree from Brown University and a master's in social science from the University of Chicago, and has worked as an independent scholar and former teacher rather than through a traditional academic post. He has written fourteen books on education and human behavior, including No Contest: The Case Against Competition and The Homework Myth, and is frequently described in the press as one of the most prominent critics of American education's reliance on grades, standardized testing, and competition.
