Exercising “rational” self-control can be very unpleasant, therefore resulting in disutility.
Example 1: When I come buy an interesting-looking book on Amazon, I can either have it shipped to me in 8 days for free, or 2 days for a few bucks. The naive rational thing to do is to select the free shipping, but you know what? That 10-day wait is more unpleasant than spending a few bucks.
Example 2: When I come home from the grocery store I’m tempted to eat all the tastiest food first. It would be more “emotionally intelligent” to spread it out over the course of the week. But that requires a lot of unpleasant resistance to temptation. Also, the plain food seems more appealing when I’m hungry and it’s the only thing in my fridge.
Of course, exercising restraint probably builds willpower, a good thing in the long run. But in some cases we should admit that our willpower is only so elastic, and that the most rational thing to do is to give in to our impulses.
What are some other seemingly “irrational” things we do that are in fact rational when we factor in the pleasantness of doing them?
