Lets say that you are facing a choice between A: Doomscrolling this morning (3 utils at time 0), B: playing ultimate frisbee with your friends this afternoon (4 utils at time 1), and C: watching a movie with some friends this evening (7 utils at time 2). Unfortunately, if you doomscroll, you make yourself too depressed to hang out with anyone for the rest of the day, and if you play frisbee you deplete all you energy for social engagements. Thus the three alternatives are mutually exclusive.

a) If you are an exponential discounter, with = 12 , what do you chose?

b) If you are a naive hyperbolic discounter, with = 12 and = 1, what do you chose?

c) If you are a sophisticated hyperbolic discounter, with = 12 and = 1, what do you choise?

d) As a sophisticated hyperbolic discounter, are you procrastinating or preproperating (doing something earlier than you should have)?
