Self-Control Problems of the Dual Self

In the previous chapter, I explained hyperbolic discounting, a source of behavioral bias which people exhibit when making intertemporal choices. Taking into account 10 years into the future while discounting tomorrow is an act that reflects humans’ dual nature. Under hyperbolic discounting, when the benefit (or the cost) of a choice is near at hand, people become motivated to prioritize the immediate benefit and revise the original plan, because the subjective discount rate suddenly increases, making them impatient. Of course, people do not always give in to such temptation and choose the “easy” option. In this chapter, I would like to refer to some data, theoretically consider what decision-making problems arise under hyperbolic discounting, and examine how we take actions to deal with these problems.
