From the moment we wake up each day, we're faced with a continuous stream of choices. Many are minor (which route to take to work), others are major (whether to accept a new job) and they all add up. When there are too many options, we tend to feel overwhelmed, anxious, stressed or otherwise out of sorts. This is decision fatigue, a state of mental overload that can impede our ability to make additional decisions.
Even if you've never heard of decision fatigue, you have probably experienced it, especially during the pandemic, which has added a new layer of complexity to the everyday choices we face. "There's no aspect of the pandemic that has not thrown decisions at us that we haven't had to make before," says psychologist Barry Schwartz, a visiting professor at the Haas School of Business at the University of California, Berkeley and author of "The Paradox of Choice." "Things that used to require no thought or effort now require a lot of planning. In the COVID world so much is uncertain - we haven't had practice making decisions under these circumstances."
Indeed, on a regular basis, many of us now wonder: Is it safe to go to an athletic event or eat indoors at a restaurant? Should we get together with friends or have people over? Is it OK to travel or go to the gym or ____ [fill in the blank]?
Furthermore, "The information we need to make decisions keeps changing," says Lynn Bufka, a practicing psychologist in Maryland and senior director for practice transformation and quality at the American Psychological Association. "And with the pandemic, some decisions are fraught with some level of risk, which can lead to anxiety, which can impair our ability to take in information and make decisions."
Decision-making is challenging under any circumstances, because there are a lot of moving pieces to the process. "People have to consider their preferences and how they're linked to their goals and values, they commit themselves to a course of action, and there are evaluative steps including cost-benefit calculations," explains consumer psychologist Kathleen Vohs, a professor of marketing at the Carlson School of Management at the University of Minnesota. "In combination, this makes it a very taxing psychological experience."
And some things make it more taxing: "The more complicated a decision is, the more it wears you out," Schwartz says.
When decision fatigue kicks in, you may feel like you just don't have the mental bandwidth to deal with more decisions. This can lead to decisional paralysis or depleted self-control, causing you to avoid making certain choices entirely, to go with the default option or to make ones that aren't in line with your goals or values, experts say.
Decision fatigue is more than just a feeling; it stems in part from changes in brain function. Research using functional magnetic resonance imaging has shown that there's a sweet spot for brain function when it comes to making choices: When people were asked to choose from sets of six, 12 or 24 items, activity was highest in the striatum and the anterior cingulate cortex - both of which coordinate various aspects of cognition, including decision-making and impulse control - when the people faced 12 choices, which was perceived as "the right amount."
