I like to encourage you all to watch the following TED talk in which the speaker present some scientific findings showing that incentive worsen the productivity for creative jobs.
At the end of this talk, speaker present some ideas for enhancing productivity for creative jobs, namely, Autonomy, excellence, and purpose. So, the idea is that we should help people excel in their field of interest and then let them to work freely, if we are really looking for increasing productivity.
Noting that the university supposedly should be a house of creativity, these advices mean revolutionizing how the current universities operate. As I mentioned in my earlier post, the current style of university, particularly, graduate studies not only does not improve creativity, it actually diminish creativity, as we can see. The current style of university even fail to help student excel in their field of interest by preoccupying them with some knowledge without providing enough time and resources for students to deepen their understandings.
I would expect from the universities to have a courage to do at least as good as google, in providing 20% of free time to graduate students to work on something that they feel is important and working in the group that they want to.
