I recently had a session with a client who came in to work on her fear of flying. We started taking the fear apart, and within half an hour it was clear that flying was barely in it.
What she was actually dreading was everything around the flight: the alarm at four in the morning, the ride to the airport, the line to check in, the line for security, the line to board, the not knowing how long any of those lines would take. By the time she was in her seat, she had already spent hours in a state she had no name for, and she had been attributing all of it to the airplane itself. Investigating her fear helped us conclude that the original problem wasn’t fear of flying but her lack of tolerance for the whole process.
Her fear improved faster than I expected once we separated those things, and that speed is what sent me back to the word tolerance itself.
I enjoy taking apart the terms we use all the time. This time it was tolerance—and what I found is that we use the same term for at least two different processes, two processes that aren’t simply variations on the same thing. They run on different machinery, and they cost the system different amounts of energy.
As an example, let’s take traffic, since most of us have sat through it at some point.
Picture one driver who is grinding his teeth in rush hour traffic that is going to make him late for work. He’s put a good song on, telling himself the music is helping. But it isn’t really. If we could measure what’s happening, we might see his heart rate up, his attention narrowed, his capacity to think a few steps ahead offline. Yet he would describe the drive afterward as fine.
Now picture, in the next car over, a woman who is also going to be late, with her child crying in the backseat. From the outside she is doing what he is doing, sitting still in a car.
But underneath, her system is doing something entirely different with it. She is working out whether to call ahead or accept the late arrival and deal with it, which means she is not avoiding the feeling of being trapped on that road. She is facing the situation and generating options, deciding what she actually needs to tolerate.
The Brain Guesses Before It Feels
Your brain does not wait for events and then respond to them. It predicts, using everything similar it has stored, and the prediction arrives before the experience does. A rude comment, a delay, a long week come already loaded with the information your brain has stored about what they are and what to do with them.
Going back to our first driver—everything his brain has stored about rush hour tells him this will be long, unpleasant, and completely outside his control. He is working to convince himself he can tolerate it, and the song is the crutch he is using to get through it. Yet what he does not notice is what the effort is costing him.
For the second driver, the stored information may be different in one specific way: Being late has happened before and she survived it. There were things she did about it that worked. Her prediction arrives with options attached. She can decide what is best, and if waiting calmly turns out to be the best of them, her tolerance is a real resource.
Notice what separates them. Both of their brains estimated how unpleasant sitting in traffic would be, and both got roughly the same answer. Where they diverged is on the second estimate: whether anything could be done.
The first driver is not really tolerating anything. He is ignoring the signals and letting the feeling go quiet, and calling that tolerance. It gets kept out of view while everything underneath keeps running, which is expensive, and the expense does not appear on any receipt he can read.
This is what I want to call passive tolerance, and it is not a form of strength. It is avoidance that has learned to present itself as strength, which makes it much harder to catch.
Where Passive Tolerance Shows Up
I see passive tolerance show up most often in three places.
Someone tolerates a partner’s dismissiveness because raising it feels more dangerous than swallowing it. They call this picking their battles. What is actually happening is that they have priced the conversation as unwinnable and are paying to avoid it.
Someone tolerates a job that is eating them because refusing anything feels like a threat to their standing. They call this professionalism. They have handed the assessment of their own worth to someone whose interests are not theirs.
And then there is the friendship that drains you, where ending it looks harder than continuing it. That one is loyalty, supposedly. It is really one difficult conversation, broken into small payments, forever.
The problem in all three is that nothing underneath gets examined, so the arrangement does not change, and the body keeps carrying it. Chronic stress of this kind is associated with memory effects and with a nervous system that grows reactive to smaller and smaller things over time.
What Active Tolerance Requires
I do not want anyone’s effort dismissed. Adopting a coping mechanism, like the first driver likely intends to do, is widely accepted as one of the best ways to handle difficult situations, and most of the time it is doing something useful.
What I want to propose is a way of practicing tolerance that does not cost you what you cannot see. Active tolerance is about knowing which mechanism you are using: a crutch, or a decision.
You stay with something on purpose, for reasons you could say out loud, instead of muting yourself so you do not have to look at it. The question is whether you know that it is unpleasant, and whether you have assessed the cost and accepted it rather than hiding it from yourself.
Which gives you the check I ask clients to run: Can you say why you are staying? A decision has reasons attached. Passive tolerance does not, because there is not a decision made. If you cannot name yours, you’re probably avoiding something rather than accepting it.
Strength is not the ability to stop feeling things. It is the capacity to feel them and stay anyway, when staying is genuinely your choice.
