Suppose in a college class, your professor offers you the following options for deadlines, based on Ariely's experiment, which would he suggest you choose with the hopes of getting higher grades:

The professor sets half the deadlines, and you set the other half.

You get to assign all your own deadlines, without any late penalties

The professor assigns all the deadlines

You set the deadlines, but you are penalized heavily for lateness

No deadlines get set at all.
