Glucksberg's experiment shows that people solve a problem faster when they are not given an incentive. Ariely's experiment shows that people are less creative when they are offered a bigger reward. The same results as Glucksberg's experiment have been found when the experiment is repeated. An incentive works for people when they are doing a simple task. Incentives will no longer work for motivating people at work when they are doing the jobs of the future. The example of the big tech companies shows that people work better when they can make choices about their work.
