And today we'll be talking about motivation. Previously, there was a saying " Offer them a reward. Do this and you'll get this. Do this faster, earn more money." So according to you, this saying is really or not? As we know, this way is common at work, at school, even at home with our family. Right? Yah. But when social psychologists test whether incentives work, they get surprising results. Sam Glucksberg, from Princeton University, America, set people a problem to solve and told them he was going to time them to see how long they took. And the result is incentives didn't work. Another study, by Dan Ariely, showed that the bigger the reward, the worse the subjects performed on a complex task. The reward made them focus so hard on the result that they couldn't think creatively any more. And this all matters because more and more simple jobs will become automated. We'll be left with creative, problem-solving jobs that computers will never do. And we need to find a way to motivate people to do those jobs. And finally we know with giving your workers freedom; freedom to work on the things they want to work on, freedom to choose when, where and how they work. This is fine. in fact some of the big tech companies are good examples of this.
