When Not Knowing Is the Hardest Part: Your Brain, Uncertainty and the AI Shift
Your brain is built to predict what comes next, so a future that keeps changing shape is genuinely tiring. That tiredness can push you toward avoidance, which feels safer but usually makes anxiety stronger. Small, deliberate steps into the unknown, paired with curiosity instead of dread, help your brain learn that you can handle more than you expect.
Why uncertainty feels so heavy right now
Many of the people I sit with in Franklin aren't facing one clear problem; they're facing a cloud of maybes. Will my job still exist in three years? Should I retrain, or wait? Is my industry about to change overnight? When the answer to every question is "nobody knows yet," the mind keeps running in the background, and it wears you down.
A recent Scientific American article by journalist Maia Szalavitz, "How uncertainty breaks the brain," helps explain why. I came across it when Owen Gregorian shared the full piece on X, and it put words to something I see in my office every week. The article notes that for many people, the world feels less predictable than at any other point in their lives, and it names artificial intelligence as one of the forces adding to that disruption.
Your brain is a prediction machine
According to the article, many neuroscientists now think of the brain as a "prediction engine." It constantly guesses what will happen next, compares those guesses with what actually happens, and adjusts. Neuroscientist Karl Friston of University College London, who developed one of the leading theories behind this idea, puts it this way: "I think uncertainty is at the heart of how we make sense of the world."
When reality matches our predictions, life feels manageable. When the gap between what we expect and what happens grows large, the brain treats it as an alarm. The article explains that these big surprises can trigger stress hormones such as cortisol to prepare the body to respond. That system works well for short bursts. It works poorly when the uncertainty never seems to end.
Psychologist Lisa Feldman Barrett of Northeastern University describes why ongoing uncertainty is so draining: "In uncertainty, your brain has to assemble many plans and maintain those plans over a period of time." In other words, your mind is quietly preparing for several futures at once.
The "dark room" trap
One of the most useful ideas in the article is what researchers call the "dark room" problem. If your brain wants to avoid surprises, the easiest solution would seem to be hiding in the most predictable place possible and staying there.
In real life, the dark room looks familiar. You stop reading the news about your field because it upsets you. You put off updating your résumé. You avoid the conversation with your boss about where the company is headed. You scroll instead of sleeping. These choices bring short-term relief, but the article explains that when you finally step back out, the world feels even more unpredictable, because you have not been gathering new information.
Psychologist Philip Kendall of Temple University describes how avoidance feeds anxiety: "The more you avoid, the more you think your prediction was accurate." Avoiding a feared situation means you never learn that you could have handled it, so the fear grows.
I also see this pattern show up as irritability. When people feel stuck in uncertainty, they often become short-tempered with the people closest to them. Anger can feel more powerful than worry, so it rushes in to fill the space. Recognizing that the snapping is really stress about the unknown is often the first step toward calming it.
What helps: building tolerance, one step at a time
The encouraging news is that the ability to handle uncertainty can grow. In the article, neuroscientist Laura Harrison compares it to building a muscle: you start with small challenges and gradually take on larger ones. Kendall's research points the same way. In a 2019 study, the more treatment reduced young people's intolerance of uncertainty, the more their anxiety fell and their daily functioning improved.
Here are practical ways to put this into practice, drawn from mindfulness-based CBT and acceptance and commitment therapy (ACT).
1. Notice when your brain is running scenarios. When you catch yourself rehearsing five possible futures, pause and name it: "My mind is planning for every outcome again." Naming the process gives you a little distance from it, and that distance makes choices possible.
2. Separate the knowable from the unknowable. Write down what you actually know this week and what you can't know yet. You may not know whether AI will reshape your role, but you do know your current responsibilities, your skills, and the people you can talk to. Put your energy into the first list.
3. Take one small step out of the dark room. Choose a single action you have been avoiding and make it smaller than feels necessary. Read one article about your industry. Spend twenty minutes trying a new tool. Ask one colleague how they are thinking about the changes. Each step teaches your brain that the unknown is survivable.
4. Reframe your body's signals. The article describes how a racing heart before a challenge can be read as fear or as readiness. When your body revs up, try telling yourself, "My body is getting ready to meet this," rather than "Something is wrong."
5. Practice curiosity on purpose. Harrison offers a helpful line: "If you expect to be surprised, you can come back more quickly." Try approaching change as something to investigate rather than something to defend against. Curiosity and fear use similar energy, but curiosity points you forward.
6. Lean on people. The article notes that resilient people tend to reach out for social support during hard stretches. Talk honestly with a spouse, a friend, or a coworker about what feels uncertain. Shared uncertainty is lighter than uncertainty carried alone.
How counseling can help
Sometimes the cloud of maybes becomes too thick to manage alone. Counseling offers a structured place to sort through it. Together we can identify the predictions your mind keeps making, test how accurate they are, and plan small, realistic steps toward the situations you have been avoiding. If stress is coming out as anger or tension at home, we can work on calming your body and communicating more clearly with the people you love.
This is the heart of my Navigate the Shift service, which focuses on adults whose work and sense of self are being shaken by AI and other technology change. It uses the same mindfulness-based CBT approach I rely on for anxiety, anger, and stress. You can learn more at navigatelifecounseling.com/shift.
Moving forward without all the answers
You don't need certainty to live well. You need enough steadiness to take the next reasonable step, and enough curiosity to keep learning as things change. Your brain can adapt to a shifting world, especially when you give it small chances to practice.

Frequently asked questions
Why does uncertainty make me so tired?
Research described in Scientific American suggests that when the future is unclear, your brain prepares several plans at once and keeps them active. That extra work, along with stress hormones, can leave you feeling drained even on days when nothing obvious happens.
Is avoiding stressful news a healthy way to cope?
Taking breaks is healthy. Long-term avoidance usually isn't, because it keeps your fears untested and can make the unknown feel even bigger. The goal is balance: limited, intentional exposure combined with rest.
Can you really get better at handling uncertainty?
Yes. Research on anxiety treatment shows that tolerance for uncertainty can improve, and when it does, anxiety tends to drop. Small, repeated steps toward what you've been avoiding are a key part of that process.
Do I need to be dealing with a layoff to use Navigate the Shift?
No. It's for anyone whose work or sense of self feels shaken by technology change, whether you've lost a role, fear you might, or are simply worn down by not knowing.
