Intolerance for Uncertainty and Anxiety
Research shows that intolerance of uncertainty is a key character trait of people who struggle with anxiety.
What Is Intolerance for Uncertainty and Anxiety?
Intolerance of uncertainty (IU) is the tendency to react negatively—emotionally, cognitively, or behaviorally—to situations that are unclear or unpredictable. People who are high in IU often experience a strong urge to know, control, or prevent future outcomes. When certainty isn’t available (which, in life, is almost always the case), this can lead to chronic anxiety and an ongoing struggle to feel at ease.
IU doesn’t just mean disliking surprises or preferring to plan ahead. It can show up as a deep, persistent discomfort with ambiguity. It often has roots in past experiences—situations where the unexpected felt overwhelming, unsafe, or out of control. Over time, the mind can begin to equate uncertainty with danger, even when there’s no real threat.
How It Shows Up in Everyday Life
- Replaying decisions long after you’ve made them, wondering if you chose “right”
- Putting things off because you’re waiting to feel more sure
- Asking others for reassurance again and again
- Struggling to enjoy the present because you’re stuck worrying about what might go wrong
- Feeling physically tense, wired, or restless for no obvious reason
This persistent discomfort can be exhausting. And the efforts to avoid uncertainty often create more stress than the original issue.
Treating Intolerance for Uncertainty
Awareness and Behavioral Shifts to Tolerate Uncertainty
Step 1. Having awareness is already a big step in better relating to uncertainty. Various situations provoke anxiety in us with their uncertainty and we may not be fully aware of why we are feeling anxious. Bring attention to the anxiety and the urge to eliminate uncertainty.
Step 2. The next step is to bring awareness to the subtle and unhealthy behaviors we do to provide assurance from the uncertainty. We may search online, ask others for reassurance, mentally review every possible outcome, or repeatedly check for signs that everything will be okay. While these behaviors often provide temporary relief, they also teach the brain that uncertainty is dangerous and must be eliminated before we can feel safe.
Step 3. Refrain from those actions meant to provide certainty. This is the hardest part, because we are resisting an urge. Try practicing a different response. The next time you notice yourself wanting certainty, pause and simply acknowledge the urge. You might say to yourself, “I’m feeling uncertain right now, and I notice that I want an answer.” Allow the feeling to be present. Over time, as you repeatedly experience uncertainty without trying to eliminate it, your brain learns an important lesson: uncertainty may be uncomfortable, but it is not dangerous, and I am capable of handling it.
With practice, the brain gradually learns the new message, leading to greater tolerance of uncertainty, in turn leading to less anxiety and feeling more calm and at peace.
