About this product

What motivates us as students, employees, and individuals?
If you reward your children for doing their homework, they will usually respond by getting it done. But is this the most effective method of motivation? No, says psychologist Edward L. Deci, who challenges traditional thinking and shows that this method actually works against performance. The best way to motivate people—at school, at work, or at home—is to support their sense of autonomy. Explaining the reasons why a task is important and then allowing as much personal freedom as possible in carrying out the task will stimulate interest and commitment, and is a much more effective approach than the standard system of reward and punishment. We are all inherently interested in the world, argues Deci, so why not nurture that interest in each other? Instead of asking, "How can I motivate people?" we should be asking, "How can I create the conditions within which people will motivate themselves?" "An insightful and provocative meditation on how people can become more genuinely engaged and succesful in pursuing their goals." — Publisher's Weekly Read more

Editor's Take

Amazon reviewers say this book is well-regarded for its clear explanation of intrinsic motivation, autonomy, and self-determination theory, and it appears to have a strong average rating with a moderate number of reviews. Goodreads readers similarly describe it as a thoughtful, influential psychology book, with several noting that it is especially useful for understanding how motivation works in everyday life. A review on Burn The Fat Blog praises the ideas but notes that the book can be less readable than its concepts deserve. Kirkus Reviews describes the central argument as a case for autonomy and internal motivation as key drivers of learning and behavior. The overall sentiment across these sources is that the book is intellectually valuable, practical, and sometimes dense, but highly respected for its ideas.
