How Boredom Helps Our Brain Do Its Best Thinking

Ever reach for your phone the instant something goes still or you have nothing to do? Or felt the itch of boredom during a commute without a podcast, a meeting that's dragging, or a line at the grocery store and suddenly need to fill the void with something, anything? Filling this gap can seem like harmless “productivity” or an innocent way to patch the discomfort. There's a decent case though, that the reflex to immediately avoid boredom is crowding out something our brain is doing to help us out.

The Discomfort Is Doing Its Job

Boredom definitely earns its bad reputation. It's an unpleasant, restless, slightly itchy feeling, and by all means most of us would rather not sit in it. Despite this, that discomfort isn't a malfunction so much as a nudge. Boredom tends to show up when whatever we're doing has stopped paying off or when the current activity no longer justifies the attention it's asking for, and its whole function seems to be pushing us to look elsewhere. 

Researchers often describe boredom as motivating the pursuit of a new goal once the old one has gone stale, with our body's arousal rising slightly to prepare for that pursuit. Seen through this frame, boredom is a signal telling us that what's happening isn't worth our attention anymore, and it tends to arrive well before we'd consciously admit that to ourselves. That’s not to say that sometimes we just have to continue forward with whatever we’re working on despite the disinterest, but it’s worth paying attention to the feeling nonetheless.

What Happens When Nothing Is Happening

Once we stop directing our attention outward, our brain doesn't just take a break. A collection of regions known as the default mode network, which has its name because it tends to switch on whenever we're not locked onto an external task, becomes more active instead. This is the network behind mind-wandering, mental drifting, and the self-generated thinking that shows up in the shower, on a walk, or staring out a window. It draws on our memories, stitches together associations, and runs quiet simulations of situations we're not currently in.

None of this requires boredom either, but boredom acts as a convenient entry point. Mind-wandering can happen during a repetitive task we're actively performing, like folding laundry or driving a familiar route. Boredom is one of the most reliable ways to get there because it's what happens once we disengage from the task in front of us, if we allow it. The less our environment demands of us, the more room this internal system has to run.

The Case for Letting a Thought Idle

This idling state turns out to be doing real work, not just filling time until our next task arrives. In one set of experiments, people who first completed a tedious task, like copying numbers from a phone book, went on to generate more creative uses for an everyday object than people who skipped the boring task entirely. The boredom itself seemed to be the determining factor because of the daydreaming people could do while copying the numbers.

A broader review across dozens of studies found that setting a problem aside for a while instead of grinding on it continuously measurably improves the odds of solving it. The benefit was more pronounced when the time away from the problem was filled with something undemanding rather than another difficult task. A wandering mind quietly working in the background turns out to be a powerful tool if we learn how to use it. The unfocused stretch is where the pieces get to rearrange themselves without us watching, often into the answer we’ve been searching for.

We’ve all likely felt this when we have an idea or answer appear to us in the shower or on a long drive. We might not have been able to solve the problem grinding away at a desk, but the time spent wrestling with it loaded the problem into our memory. When we let our mind wander, the problem circulates around and our brain often pieces together the answer or at least makes progress.

Why We Keep Interrupting Boredom

Despite all this, boredom probably won’t ever be pleasant, which is exactly why we're so quick to escape it. The trouble is that escaping it may be teaching us to escape it faster every time, preventing the benefits we can reap by just sitting with it. 

It's different for every person, and reaching for a phone or other escape during a dull stretch isn’t inherently a problem. Plenty of boredom is genuinely worth escaping, and nobody needs to suffer through a slow checkout line for the sake of their creativity. When the escape happens automatically though, before the boredom has had a chance to do anything, we may be trading away the very stretch of unstructured attention that would have eventually turned into an idea, a solved problem, or just a clearer sense of what we actually wanted to be doing instead.

Letting the Feeling Run Its Course

Boredom is a tool to utilize when we want rather than avoid altogether. If we can reframe it as something to notice the moment the discomfort arrives, it can give us the chance to ask what it might be nudging us toward before we disregard it. Sometimes that's nothing more than a few minutes where our mind gets to wander undirected and unsupervised, doing the kind of work it apparently can't do any other way. We don't have to like the feeling to trust that it's pointed at something productive.
