Every person is isolated from the others, to avoid any influence.
There is a clock in the setting, thus the volunteers can check the time.
The assigned tasks is a general culture questionnaire, which can be completed in 15 minutes.
The first control group do not receive any time indication.
The second group receive a deadline, corresponding to the average time needed to complete the task, doubled (approx. 30 minutes).
The same duration is given to the third group, but as a simple estimation.
The first and the third group do not have any time restriction to complete the task.
After returning the worksheet, the volunteers of group two and three are asked to evaluate if the time given/indicated were fair, and how much time would it take to conduct another similar task.
