When someone stays composed while everything around them isn’t, the usual explanation is that they simply feel less than the rest of us. Their internal alarm is quieter, so there’s less for them to manage. It’s an intuitive theory, and it’s mostly wrong.

People who score high on measures of equanimity tend to notice their own irritation and anxiety sooner than average, not later. The initial reaction is fully intact. What’s different is what happens in the moments right after it, and that difference turns out to be a habit rather than a temperament .

The Habit Of Never Acting On Your First Reaction

Psychologists measure something called non-reactivity to inner experience, one of five components tracked in standard assessments of mindfulness. It describes a narrow skill: noticing that a thought or feeling has arrived and allowing it to be there without immediately trying to do something about it.

Most people do the opposite without ever deciding to. Anxiety shows up before a difficult conversation, and the response is an internal argument about whether it should be there and how to get rid of it before the conversation starts. The original discomfort is now competing for attention with the effort to eliminate it, and the effort usually outlasts what it was meant to fix.

What deeply calm people skip is that second layer. The anxiety still arrives on time. It just doesn’t get taken up as a problem that has to be solved before anything else can happen.

What This Habit Really Fixes

There’s a well-established finding behind this. A 2020 meta-analysis published in Perspectives on Psychological Science confirms that deliberately pushing an unwanted thought out of awareness reliably makes it resurge later rather than fade, because staying alert for the thing you’re trying not to have keeps it in view. Telling someone not to think about something is a fairly reliable method of ensuring they do.

Research on emotion regulation lands in a similar place. A now-classic 1999 study published in Personality and Social Psychology Bulletin found that suppressing an emotional expression reliably impaired memory for whatever was happening during the suppression, and raised cardiovascular activation on top of it.

Suppression is the costly strategy. It reduces what other people see while leaving the internal experience roughly where it was, and the monitoring it requires draws on mental resources that would otherwise be available for whatever is actually happening.

This is why the person visibly working at being serene often ends up more depleted than the person who looks unbothered. The second person may be doing considerably less, having never entered the struggle at all .

Why This Habit Isn't The Same As Not Caring

Non-reactivity is easy to mistake for detachment, or for a determined refusal to acknowledge anything unpleasant. It usually involves more contact with difficult feeling than average rather than less, since nothing is being held at arm’s length.

That’s the premise of acceptance and commitment therapy , where the aim isn’t a better mood but psychological flexibility, meaning the capacity to carry an uncomfortable internal state and still do what matters.

A 2024 meta-analysis published in Behavior Therapy , pooling 151 studies, found this link between flexibility and well-being to be one of the more consistent findings in the field. The measure of the skill isn’t how someone feels. It’s whether the feeling ends up deciding what they do.

In practice this makes genuinely equanimous people fairly direct. They’ll raise the awkward subject and sit through the silence that follows, because the discomfort of doing so doesn’t set off a second alarm that has to be handled first.

How To Get Better At Using This Habit

The habit is trainable, though the training is duller than the result makes it look. It mostly consists of putting a small gap between something landing and responding to it, then using that gap to register what you’re actually feeling.

Naming the feeling privately helps more than it sounds like it would. A 2025 scoping review published in Journal of Psychiatric Research synthesized this literature and found that people who describe their emotions in specific terms rather than general ones consistently regulate them more effectively than people who don’t.

There’s also a goal that has to be quietly abandoned. Most people practicing calm are still trying to feel better right away, which turns the practice into another version of the struggle it was meant to replace. What changes things is letting the feeling run its course without supervision.

One nuance is worth adding here. This isn’t a fixed trait that someone either has or lacks, and it varies within the same person depending on what’s at stake. Most people are unusually steady about some things while remaining quite reactive about whatever sits closest to how they see themselves.

The people who seem unshakeable haven’t found a way to stop the first reaction from happening. They’ve stopped treating it as something requiring their immediate attention, and from the outside, that omission reads as calm.
