Picture a small room with a radio in it, and the radio is stuck on one station. It is half past eleven on a bad night, you are lying in the dark with the landing light showing under the door, and the only voice in the house is saying the sentence you know by heart: I’ve got this wrong, haven’t I? Everybody else can manage. You have argued with it. You have agreed with it. You have tried to turn it off at the wall. It plays on, and you are inside the room with it.
Now imagine that, without winning a single argument, you took one step backwards and stood in the doorway. The radio is still playing, word for word. But you are looking at it now, rather than living inside it. That step has a name. Psychologists call it decentering: the ability to observe your thoughts and feelings as passing mental events, not as accurate reports about you or the world. It is a small step, and you can practise it.
This post looks at two pieces of recent research on decentering: what they found, what they did not, and how you can try the skill for yourself tonight. If you are waiting for an assessment, newly diagnosed and still learning the vocabulary, or holding a letter from school that you have already read three times, you may not have much patience left for theory. So the practical part is not tucked away at the end. It is all here, in plain language.
Noticing is not the same as agreeing
Most of the advice you are handed about anxious or low thinking pushes in one direction: change the thought. Challenge it, replace it, argue it down. That is the heart of cognitive behavioural therapy (CBT), a well-established talking therapy built on the idea that your thoughts, feelings and behaviours are tightly linked. It helps a great many people. But underneath it sits a quieter skill that makes the rest possible: before you can weigh a thought, you have to see that it is a thought at all.
Look at the difference between two sentences. I am a failure is a verdict. I am having the thought that I am a failure is an observation. The words barely change, yet the second leaves a small gap between you and what you are noticing, and that gap is where choice lives. You are not being asked to believe the thought is false, or to feel cheerful about it, or to push it away. You are being asked to notice it without immediately obeying it.
Has that ever happened to you? On a good day, a worry passes through, you think there’s that one again, and you carry on making the tea. If so, you already know the skill exists. The research asks whether it can be trained, and whether it is the ingredient doing the work when therapies that teach it help.
Where CBT and mindfulness meet
Decentering matters partly because of where it sits. CBT teaches you to examine your thoughts. Mindfulness, the practice of paying attention to the present moment on purpose and without judging it, teaches you to notice them. Decentering is the point where those two ideas overlap.
One well-known therapy is built on that overlap. Mindfulness-based cognitive therapy (MBCT) is a structured group programme that combines mindfulness practice with ideas from CBT, and it was originally developed to help people at risk of relapse into depression. Another family of approaches, including acceptance and commitment therapy, focuses on acceptance: making room for uncomfortable experience instead of fighting it. All of them share a suspicion that changing your relationship with your thoughts can matter as much as changing the thoughts themselves. Which raises the obvious question, and it is a fair one: is that suspicion actually true?
It matters to you because it changes what “trying” looks like. If therapy were only about winning arguments with your thoughts, a bad night would mean you had lost. If part of it is learning to see a thought as a thought, a bad night is simply more practice with the same material. The thought can turn up exactly as loud as before, and you can still count the evening as time spent building the skill.
What the pooled evidence says
The clearest overview comes from a systematic review and meta-analysis published in Clinical Psychology Review in June 2022 by Maja Johannsen, Eva Rames Nissen, Marie Lundorff and Mia Skytte O’Toole. A meta-analysis gathers many separate studies and combines their results, so you are not relying on a single trial that might have been a fluke. The team screened 4,989 records and ended with 33 eligible studies, drawn from 30 independent trials, all looking at acceptance-based and mindfulness-based therapies for anxiety and depression.
Their question was a subtle one. It was not “do these therapies help?” It was “what is the therapy changing that produces the help?” They tested three candidates: mindful attention (staying aware of the present moment), decentering (the step backwards) and acceptance. Across the studies, the pooled mediating effect of the three was small to medium, with a correlation of r = 0.145 (p < .001). In plain language, changes in these skills were linked to improvement in a real, measurable, but modest way.
Stay with the word modest for a moment. A small-to-medium effect is not a miracle, and you should be wary of anyone who sells it as one. But it is not nothing either. It suggests that what you practise when you learn to notice thoughts without judging them is genuinely part of how these therapies work.
The brooding study: when life goes badly
The second piece of evidence asks a sharper question: does decentering help when things actually go wrong? A team led by Wu, with Hamilton, Fresco, Alloy and Stange, published a study in Behaviour Research and Therapy (online in December 2021, in the May 2022 issue). They followed 181 undergraduate students, 157 of whom were included in the analyses, and assessed them five times across 12 weeks, at three-week intervals. Following the same students over time matters, because it lets researchers watch what happens after a stressful event instead of relying on memory.
They focused on perseverative thinking, the habit of going round the same loop again and again, in three forms. Brooding is the passive, self-blaming kind: why does this always happen to me? Pondering is a more reflective turning-over of a problem. Worry is the future-facing version: what if it goes wrong? You will probably recognise all three from your own 3 a.m.
Here is what the team found. Students higher in decentering showed a weaker link between negative life events and brooding. When something went wrong, the ones who could step back from their thoughts were less likely to be pulled into the self-blaming loop. And for brooding, pondering and worry alike, higher decentering weakened the connection between the thinking and symptoms of depression and anxiety. The loop still turned. It simply did less damage.
Think of it as a buffer, not a shield. It did not stop the bad week from happening, and it did not stop the worry from arriving. It changed what the worry could do once it got there.
What these studies cannot tell you
Here I want to slow down, because hope without honesty helps no one. Before you carry any of this to your GP, your therapist or your own bathroom mirror, these limits are worth knowing. They are there to protect you from expecting too much, or from blaming yourself if it does not work.
First, the students. The brooding study used university undergraduates, so it tells you what happened in that group. It cannot tell you that the same pattern holds if you are managing a long-term condition, caring for a child, working nights or living with trauma. Not every prediction held up, either: decentering did not soften the link between stress and pondering, or between stress and worry, only between stress and brooding. One of the statistical models also failed to converge, which means it could not be completed.
Second, the meta-analysis carries a caution that is easy to miss. The only factor that significantly changed the results was the type of analysis. Correlation-based approaches showed the effect. Causal time-lag analyses, which check that the change in the skill came before the change in symptoms, did not. The authors were clear that their limitations restrict what can be said about specificity and causality. Put plainly: the evidence shows that decentering travels alongside improvement. It does not yet prove that decentering is what causes it. If a step feels hard, that is not evidence that you are doing it wrong.
Third, none of this work was designed around ADHD. If you live with ADHD, or you are the parent of a child who does, you may reasonably wonder whether a skill that asks you to watch your own thoughts steadily will feel harder, not easier. The honest answer is that these studies cannot say. Anything said about ADHD from here is an extension of the findings, not a result of them, so treat it as something to try gently and judge by how it works for you.
Turning the research into something you can do
Whether you are on the waiting list for NHS Talking Therapies, handed a self-help leaflet, or simply tired of arguing with your own head, these steps are small enough to try tonight. None of them needs a cushion, a candle or a calm mind.
- Add the four words. When a hard thought lands, silently begin it with “I’m having the thought that…”. Say it once. You are not fixing anything. You are changing the grammar so the thought becomes something you are holding rather than something you are inside.
- Name the type, not the content. Try “brooding”, “worrying” or “planning”. Naming the kind of thinking is often easier than answering what it says, and it shows you whether you are looping or solving.
- Give it a location. Notice where the thought sits in your body, perhaps a tight jaw or a heavy chest, and stay with that sensation for three slow breaths. The aim is not to relax. It is to notice.
- Write it down and look at it. A thought on paper is visibly separate from you. Three lines on the back of an envelope will do.
- Keep the timing short. One or two minutes, a few times a day, is enough to begin. A skill built in small pieces survives a bad week better than one attempted in a heroic hour.
A word on what to expect. The first few attempts often feel awkward, a bit like saying a sentence in a language you are only just learning. The thought may not shrink at all. What usually shifts first is smaller: a second of space before you react, or the sense that you are the one reading the thought rather than the one being read aloud. That second is the whole skill in miniature, and it is worth noticing when it happens.
Which one could you try before you go to sleep tonight? Pick one. Only one.
If a thought ever moves from unpleasant to frightening, or turns towards harming yourself, this is no longer a skills exercise. Speak to your GP promptly, or call Samaritans free on 116 123 at any hour. Noticing without judging is a support for everyday distress, not a substitute for help when you need it.
Where this leaves you
The lesson underneath both studies is a gentle one. You do not have to win the argument with your own mind. You do not have to defeat the midnight thought, or prove it wrong, or feel calm before you are allowed to get on with your life. You can let it speak, notice that it is speaking, and step back into the doorway.
Some nights that step will feel impossible. It will not work. That is allowed. Try again the following evening, a minute at a time, and the gap widens by a hair. The research says the effect is modest and real, and modest and real is exactly the kind of change that adds up quietly over months. It is available to you at the next quiet moment you find, and you are far from the only one in the doorway.
