Punished by Rewards: The Trouble with Gold Stars, Incentive Plans, A's, Praise and Other Bribes

The basic strategy we use for raising children, teaching students, and managing workers can be summarised in six words: "Do this and you'll get that." We dangle goodies (from candy bars to sales commissions) in front of people in much the same way we train the family pet. Drawing on a wealth of psychological research, Alfie Kohn points the way to a more successful strategy based on working with people instead of doing things to them.
'Do rewards motivate people?' asks Kohn. 'Yes. They motivate people to get rewards.'
Seasoned with humour and familiar examples, 'Punished By Rewards' presents an argument unsettling to hear but impossible to dismiss.
