I recommend THIS REVIEW
for a description of this book that's better than any review that I might write.
This book describes how the usual measures taken to promote motivation in people can have results opposite of what was intended. These unintended consequences have long been demonstrated by psychologists, but businesses and schools have been slow to make use of this information. All the time I was listening to this book I was thinking about how difficult it is to change social situations to take advantage of the information discussed in this book.
