Unknown result when the job motivates people. This is the conclusion reached by scientists from the University of Hong Kong and the University of Chicago. They invited the volunteers to drink large amounts of water. As a reward one group received two dollars, the award of the second group was determined by a coin (one to two dollars). Volunteers from the second group coped with the task better, writes Psych Central.
In the second experiment assumptions scientists have confirmed. In an impromptu auction played out a box of chocolates. One group of volunteers knew that it is 4 candy, the other received abstract information. Rate of the second group was higher. Scientists call the phenomenon described motivating effect of uncertainty.
The unknown before the pushes on risky behavior and motivates to action. On the same principle operate slot machines and many other systems, artificially guides man in the right industry direction.
