While there are thousands, millions, maybe billions of answers to that question, a growing body of research, some of it dating back 50 years, shows two things that don’t motivate us very well – the promise of rewards and the threat of punishment.
It seems counter-intuitive, since after all we take it for granted that we need incentives to do work. It’s the basis of our whole economic system, for crying out loud! And yet, the research is abundantly clear: once a reasonable standard of living is achieved, rewards and punishment not only don’t motivate us to do more, better, or faster, they oftendemotivate us.
