Reading time: 5 minutes

Every Sunday I go running. But the Sunday after Christmas I could not get myself to get off the couch, whereas on other Sundays it is not that difficult. I had a busy morning tidying the house and cleaning up the kitchen and the refrigerator from the Christmas meals I made. My wife and I also had some discussions about the activities and meals in the days to come. On top of that it had been raining all morning, which is not very motivating for a run outside. I just could not get myself to spring into action.

Decision fatigue

When I took a minute to reflect, this seemed like a classic example of decision fatigue. This refers to people’s diminished capacity to regulate their thoughts, feelings, and actions, because people have a finite amount of willpower that becomes depleted as they use it. When I cleaned up the kitchen and the house that Sunday morning, I had to make many decisions. Clean the wine glasses first or take out the trash first? What to keep in the refrigerator: are we still going to eat this cream cheese in the near future and do I really see this happening? What do we eat for breakfast today, what about this evening or the rest of the week? These decisions may seem benign, but they reduced my capacity to regulate my action towards running, because all these decisions had depleted my willpower.

Willpower and self-control

A classic study investigating willpower was done by Stanford professor Walter Mischel in 1972, which has become known as the Stanford marshmallow experiment. He invited 50 children between the age of three and five to his laboratory. They were placed in a room without any distractions and were told they could either eat the one marshmallow sitting in front of them immediately or eat two later. The children had to use their willpower to control themselves from eating the marshmallow in order to receive a larger reward later. You can see children struggling with this task in the video below.

As you can see, many children are struggling to control themselves. Presumably, this is caused by the many decisions these children are making by constantly asking themselves whether to eat the marshmallow right now or wait so they can get another one. These many decisions deplete their willpower, so that many of these children experience decision fatigue and eat the marshmallow after some passage of time.

Using willpower and self-control is often connected to better outcomes later in life. When Mischel followed up on these children later in their lives, he found a strong correlation between their results on the marshmallow test and their success in life. The children that showed more self-control on the marshmallow test, turned out to be more cognitively and socially competent, achieved higher performance in school and were coping better with frustration and stress.

Parole decisions

Now that you know about decision fatigue, try guessing which two men were denied parole and had to remain in prison. These are four real-life cases taken from parole boards that serve four major prisons in Israel.

  • Case 1 (heard at 8:50): An Arab-Israeli male serving a 30-month sentence for fraud.
  • Case 2 (heard at 13:27): A Jewish-Israeli male serving a 16-month sentence for assault.
  • Case 3 (heard at 15:10): A Jewish-Israeli male serving a 16-month sentence for assault.
  • Case 4 (heard at 13:27): An Arab-Israeli male serving a 30-month sentence for fraud.

Requests for parole were heard by a board in daylong sessions. You probably have guessed that prisoners appearing early in the day were more likely to receive parole then prisoners appeared late in the day. Therefore case 1 received parole, whereas case 4 was denied. Thus, making many decisions during the day lead to decision fatigue among the judges and influenced their decisions about prisoners later in the day.

Furthermore, the researchers Danziger, Levav, and Avnaim-Pesso, also found that prisoners appearing after breakfast, coffee-breaks, and lunch were more likely to receive parole than prisoners appearing just before these breaks. This lead to case 2 receiving parole, whereas case 3 was denied. Thus, taking breaks apparently diminished decision fatigue.

Decision fatigue and habits

The marshmallow experiment suggests that willpower and self-control are innate, and that it may prove difficult for you to control decision fatigue. However, results from a study by psychologists Hofmann, Baumeister, Förster, and Vohs show that controlling decision fatigue may be in the reach of everyone. Their study investigated willpower and self-control the participants were experiencing. They filled out questionnaires about self-control with statements such as “I am good at resisting temptations”. Furthermore, they received messages on their mobile phones at random moments asking them questions about the desires, temptations, and self-control at that particular moment.

The results showed that the people who were the best at self-control reported fewer temptations. Thus, people who said they were good at self-control were hardly using it at all. It turned out that people who are good at self-control are structuring their lives to avoid having to use willpower and self-control. People who do the same activity at the same time each day do not have to use their willpower, but they use the routine to make the activity easier to do. So these people make a habit out of their desired activity.

This is what was happening to me on this Sunday afternoon when I could not get myself to get off the couch. I have made running on Sunday a habit, but this did not appear to me as a regular Sunday and thus my routine was interrupted and my willpower waned and decision fatigue set in.

Support for your good intentions for the New Year

Here are three tricks that you can use to combat decision fatigue and built solid habits.

  1. First, define clear and attainable goals. In my case, on Sundays I go running.
  2. Second, draw bright lines. A bright-line rule refers to a clearly defined rule or standard. It is a rule with clear interpretation and very little wiggle room. It establishes a bright line for what the rule is saying and what it is not saying.

    In my case, I can go running anytime on Sunday, but I have to do it anytime between getting up on Sunday morning and going to bed Sunday night. Because I am aware that decision fatigue can always get the best of me, I plan to do it as early in the morning as I can. If I foresee that Sunday will not be possible, then I plan to do it on an earlier day. For me this creates a clear guideline with very little wiggle room.
  3. Third, request social support. Ask people to support and encourage the desired behavior. This is especially important in the early stages of forming a new habit, before it becomes a routine. In my case, I ask for support from my family and publish my intentions in blogs.

So, I would really appreciate if you encourage me in the comments to go running next Sunday. I would really appreciate your support! I promise I will support your good intentions for the New Year as well.
