If you know that your effort is making a difference, do you put in an extra shift?
In her Bachelor thesis, Lisa Falkenreck examines whether people who are asked to engage in a certain task are more willing to put in effort if they know that the task is helpful to others. Lisa carried out a field experiment, to find the answer to her question. She asked subjects to pack sweets, either informing them or not informing them about the purpose for which these packs are created. She finds that they pack more, if they know for what purpose these packed sweets will be used.
