New research published recently in the New York Times provides a fascinating look at how our brains work when required to make important decisions. The findings could have serious implications for people trying to avoid debt, rebuild after bankruptcy, or stick to a budget.
What Is Decision Fatigue?
Decision fatigue is exactly what it sounds like: a phenomenon that occurs when a person has made too many choices. Intriguingly:
- Each decision a person makes requires energy.
- We all have limits to our mental energy, but we may not realize we’re approaching those limits.
- As we make decisions throughout the day, our mental energy is depleted. It can be restored with rest and food.
- Poor people are reportedly more susceptible to decision fatigue than rich people because those with less money generally have to put more energy into each purchasing decision they make. Having fewer resources means that every spending choice has higher stakes.
- Decision fatigue can lead to impulse buying, overextending yourself on credit and otherwise making the sort of purchases you wouldn’t if you had your full mental reserves available.
We’re wired to deal with decision fatigue in two ways: by acting impulsively or by making no decision at all. Clearly, either of those options can have serious side effects, especially if debt is on the line.
How Can I Fight Decision Fatigue?
We have to make so many decisions each day, we may not realize we’re making them: what to wear, what to eat for breakfast, what to pack for lunch, which lane to drive in, where to park – and that’s before getting to work.
Researchers have found that there are some key ways to fight decision fatigue and maximize your effectiveness throughout the day:
- Plan ahead: Set out your clothes, pack your lunch and decide on breakfast before bed. In the morning, you can breeze through without stressing about minor things.
- Schedule major decisions: If you know you have to make important decisions (e.g. buy a car or lead a big meeting at work), plan ahead. Make sure to get enough rest beforehand and to approach the decision with a full stomach.
- Space major decisions: While it may seem productive to schedule major decisions or projects close together, you’ll probably serve yourself better by giving your brain a break between them.
- Have a snack on hand: One encouraging finding of the decision fatigue research was that there is a simple way to fight back: eat something. The rush of glucose to the blood and brain we get from eating can help rejuvenate our energy and make decisions a little less overwhelming.
