Rehearsing a conversation in the shower, in the car, in the three minutes between pulling into the driveway and walking through the door, is not the behavior of a person who can’t handle a feeling. It’s the behavior of a person who has learned, often painfully, that feelings get misrouted in transit. The words leave the mouth meaning one thing and arrive in the other person’s ear meaning something else entirely. Rehearsal is an attempt to close that gap.

We call this anxiety because anxiety is the easiest diagnosis in a culture that pathologizes preparation. The label is wrong. What’s actually happening is closer to translation work.

The inner voice is doing more than narrating

Most people carry an inner monologue. Not everyone, as it turns out. Some people report almost no verbal thought at all, a fact that still surprises researchers studying how cognition varies across individuals. For the majority who do hear themselves think, that voice has a job description broader than commentary. It rehearses. It drafts. It edits in real time.

The showerhead is just a convenient acoustic chamber for a process that was going to happen anyway. What the water provides is enough sensory noise to quiet the day’s interruptions, so the internal drafting room can finally hold a meeting. The conversation being rehearsed is almost never with a stranger. It’s with a spouse, a parent, a boss, someone whose reactions the rehearser has studied long enough to predict.

Where the habit comes from

Daniel Kopala-Sibley, a psychology professor at the University of Calgary, has spent years studying how childhood shapes self-critical adult patterns. In reporting by BBC Science Focus, Kopala-Sibley notes that experiences of parents being critical, controlling, or uncaring are robustly associated with high levels of self-criticism in adulthood. Research in this area also suggests that young adults who recall being bullied or excluded tend to be more self-critical as well.

That research tracks a deeper pattern. If you grew up in a house where the wrong word at dinner could shift the emotional weather for the whole evening, you didn’t develop anxiety. You developed a drafting process. You learned to audition sentences before sending them out, because unedited sentences had consequences you couldn’t walk back.

What the brain is actually doing in there

The neuroscience of inner speech is finally starting to catch up with the phenomenology. When people silently rehearse a syllable and then hear that same syllable played aloud, the auditory cortex response is measurably suppressed compared to hearing an unexpected sound — a finding consistent with what researchers call an efference copy, where the brain sends a prediction of its own internal speech to sensory areas and dampens the incoming signal when reality matches the forecast. In plainer terms: the brain is issuing a draft of what it expects to hear itself say, then checking the room against the draft.

That prediction mechanism is the same one at work every time you silently try out a sentence before saying it. The brain is modeling how the sentence will sound, how it will be received, and adjusting before anything leaves your mouth. For people whose environments made miscommunication expensive, that forecasting runs more often and more thoroughly.

Live Science has detailed how inner speech activates many of the same regions as outer speech — including Broca’s area and the left inferior frontal gyrus, structures central to speech production — which is why rehearsed sentences feel almost spoken. You aren’t imagining the conversation from the outside. You’re running it through most of the same machinery you’d use to actually have it.

The difference between anxiety and translation

Anxiety is a general alarm state. Translation is specific. The rehearser in the shower is not worried about a vague future. They are solving a particular problem: how to say something true in a way that won’t be heard as an attack, a demand, a complaint, or a weakness.

This is where the diagnosis of anxiety misses. Anxiety would produce avoidance. The rehearser is doing the opposite of avoidance. They are doing preparation so thorough that the conversation can actually happen. The person who rehearses is often the person who eventually brings up the hard thing, while the person who truly avoids never brings it up at all.

My wife’s work in immigration law has given me a close view of this distinction. She spends whole afternoons helping clients rehearse how to tell a story to an officer who will decide their future in fifteen minutes. The rehearsal isn’t fear. It’s recognition that the listener has power, that the words have to arrive in a specific shape, and that spontaneity in a high-stakes room can cost a person everything. That’s not a pathology. That’s a realistic assessment of asymmetric stakes.

Most private rehearsal runs on the same logic at a smaller scale. The stakes are a relationship instead of a residency, but the math is similar.

The inner critic is not the rehearser

It’s easy to confuse rehearsal with self-attack. They share an acoustic space. But they are doing different things.

Paul Gilbert, a clinical psychology professor at the University of Derby, calls habitual negative self-talk a form of self-attacking rather than self-improvement. His research, as reported by BBC Science Focus, shows that self-criticism activates the anterior cingulate cortex and amygdala — the same threat-response circuits that fire when we’re being attacked by someone else. The critic isn’t trying to help. It’s performing dominance over its own host.

The rehearser is different. The rehearser is trying to be understood. You can tell the two apart by listening to what the inner voice is actually doing. If the inner voice says something like you’re stupid, you’ll blow this, that’s the critic. If it says something like if I lead with this, she’ll feel blamed — try the other framing, that’s the translator. The first voice wants to shrink you. The second voice wants you to land.

Most chronic rehearsers have both voices running. The trouble is when the critic hijacks the rehearsal and turns it into evidence-gathering for later self-punishment.

Why the shower specifically

There’s a reason the rehearsal happens in the shower, the car, the walk. These are environments that occupy just enough of the body to let the verbal mind work without interruption. Researchers have described this kind of variation in how people experience their own thoughts — some in words, some in images, some in something closer to sensation. Whatever the format, these low-demand environments are where the drafting gets done.

Office hours don’t allow it. Conversations don’t allow it. Phones don’t allow it. The shower is one of the last rooms in modern life where nothing asks for your attention, which means the backlog of undelivered sentences finally gets a stage.

That’s also why the rehearsals can feel compulsive. They aren’t happening because the person is broken. They’re happening because the rest of life doesn’t give the verbal mind any other time to do this work, and the work is real.

When rehearsal becomes a trap

The failure mode isn’t rehearsal itself. It’s when rehearsal replaces the conversation.

Some rehearsers run the conversation so many times, from so many angles, that by the time they see the other person they feel like the conversation has already happened. They’ve anticipated every possible response, edited around every possible misreading, and the exchange in their head has become more vivid than any real exchange could be. Then the real conversation feels disappointing, because it can’t compete with the fully produced version.

Others rehearse so thoroughly that they pre-emptively decide the conversation isn’t worth having. The translator finds no version of the sentence that would land cleanly and concludes the silence is safer. This is how partnerships quietly accumulate unsaid things.

The pattern is familiar: the distance that builds up between a person and the people they love when they keep too much of themselves in the drafting room. Rehearsal taken too far becomes a kind of performance that the people around you eventually notice. They don’t know you’re rehearsing. They just feel that they’re never quite meeting the unedited you.

The goal isn’t to stop rehearsing

The cultural advice on this tends to be unhelpful — suggestions to be spontaneous, say what you feel, or avoid overthinking assume the rehearser is neurotic rather than realistic.

The better question isn’t how to stop rehearsing. It’s whether the audience you’re rehearsing for still deserves that much careful translation. Some do. A boss who controls your salary, a parent whose approval still matters, a partner going through something fragile — those are reasonable rooms to enter prepared.

But rehearsal becomes expensive when it’s universal. If you’re drafting every sentence for every person, the translator has generalized a protective reflex from a few dangerous rooms to every room you walk into. That’s where the work is. Not stopping the rehearsal, but narrowing it.

Ethan Kross, a psychologist at the University of Michigan whose work on inner speech has been widely covered, has suggested small linguistic tools that change the texture of self-talk — like referring to yourself in the second or third person, which creates a small distance between the self doing the thinking and the self being spoken to. The Guardian’s coverage of Kross’s research describes how this distancing can help regulate the volume of the inner voice, especially when it tips from drafting into attacking.

What the rehearser is actually looking for

Strip the habit down to its motive and what you find is not fear. It’s a search for a version of yourself that the other person will receive accurately. The rehearser is not trying to manipulate. They are trying to be known without being misread, which is one of the most basic human needs and one of the hardest to meet.

The sentences get tried on the way you try on clothes before a meeting that matters. Too casual? Too sharp? Too soft? The goal isn’t to seem like someone else. The goal is to finally seem like yourself, in a room where previous versions of yourself got misunderstood.

That’s a lonelier project than anxiety. Anxiety has company. Every therapist has a framework for it. Translation work doesn’t get the same recognition, partly because it looks, from the outside, identical to worrying.

The person rehearsing in the shower isn’t spinning. They’re composing. And the thing they’re composing is usually a version of the truth they believe the other person can actually hold.

A quieter ending

Not every conversation needs translation. Some of the people in your life can hear you when you’re rough, tired, unedited, wrong. Those people are rare, and you know who they are without having to think about it.

For everyone else, rehearsal is a reasonable response to the fact that language is lossy and listeners are imperfect. The habit is not a flaw to be fixed. It is a skill to be aimed more narrowly, at the rooms where it’s actually earning its keep.

This is the line worth holding onto: anxiety is rehearsal that has forgotten its audience and begun running on its own momentum, drafting for rooms you’ll never enter and people who aren’t even listening. Translation is rehearsal that still knows who it’s for. One is a loop. The other is a letter.

The shower thought isn’t a symptom. It’s a draft. The question worth asking isn’t why you keep drafting — it’s who you’re drafting for, and whether they’ve done anything to deserve that much of your careful attention. When the answer is yes, the rehearsal is a gift you’re preparing to give. When the answer is no, it’s time to close the notebook and walk out of the drafting room.
