There is a psychological study, where two group of people are asked to do some task for pay. Afterward they have to rate how engaging was the task they have to do. The group who are paid well reported that the work was boring. While the group who are paid little reported that the task was fun and challenging. The task was the same for both groups, but the first one justifies it by having compensation. While the second one by making the task fun or more cynically by deluding themselves that it has some kind of value.
