Quick answer: Cognitive distortions are habitual, unhelpful ways of thinking that bend how you see a situation, usually towards the negative. Common examples are catastrophising (expecting the worst), all-or-nothing thinking, mind reading and "should" statements. You can challenge them by catching the thought, naming the pattern, checking the evidence for and against it, and writing a more balanced alternative. Everyone has them, and noticing them is a skill you can practise.
Key takeaways
Cognitive distortions are automatic thinking habits, not character flaws. Everyone has them sometimes.
The 10 most common include all-or-nothing thinking, overgeneralisation, mental filtering, jumping to conclusions and catastrophising.
Naming the distortion ("that's catastrophising") creates a little distance from the thought.
Challenging a thought means checking the evidence, not forcing yourself to think positively.
Writing thoughts down close to when they happen makes patterns much easier to see over time.
What are cognitive distortions?
Cognitive distortions are biased ways of interpreting what happens to us. They tend to show up as quick, automatic thoughts that feel true in the moment: "I've ruined everything", "they think I'm useless", "this is going to be a disaster." They aren't lies you tell yourself on purpose. They're mental shortcuts that skip over the facts and land on the most painful conclusion.
The idea comes from cognitive therapy, which grew into cognitive behavioural therapy (CBT, or cognitive behavioral therapy in the US and Canada). Mind describes CBT as focusing on how your thoughts, beliefs and attitudes affect your feelings and actions, and notes that how we think about situations can affect the way we feel and behave. If you're new to CBT, our guide to what CBT is and how it works covers the basics.
NHS Every Mind Matters calls these patterns unhelpful thinking and explains that thoughts, feelings and behaviours affect one another, so an unhelpful thought can start a cycle. You feel anxious, you avoid something, the avoidance seems to confirm the fear, and the next thought is even harsher. Spotting the distortion is how you start to break that loop.
Why do cognitive distortions matter?
On their own, a few distorted thoughts are just part of being human. The trouble comes when the same patterns repeat. Expecting the worst over and over can keep you stressed and on edge. Labelling yourself after every mistake can wear down your confidence. Assuming you know what others think can make you withdraw from people or misread situations. Believing you'll fail can stop you trying at all.
None of this means you need to get rid of every negative thought. The aim is to notice when a thought is doing more harm than good, and to give yourself a fairer, more complete version of events.
What are the 10 most common cognitive distortions?
Different therapists and workbooks use slightly different names and groupings, but these ten come up again and again. Use the last column as a starting point when you notice one.
Distortion | What it sounds like | Example thought | Question to challenge it |
1. All-or-nothing (black-and-white) thinking | Things are perfect or a failure, with nothing in between | "If I don't get this perfect, I've failed." | Is there a middle ground? What would 'good enough' look like? |
2. Overgeneralisation | One event becomes a rule, often with 'always' or 'never' | "I messed up that presentation, so I'll always be bad at public speaking." | Is this one time, or truly always? Can I think of an exception? |
3. Mental filter | Focusing on one negative detail and ignoring the rest | "I got lots of good feedback, but all I can think about is the one criticism." | What am I leaving out? What would a full summary say? |
4. Discounting the positive | Good things 'don't count' | "They're only saying that to be nice." | What if I took this at face value? Would I discount it for a friend? |
5. Jumping to conclusions (mind reading, fortune telling) | Assuming what others think or what will happen, without evidence | "They haven't replied, so they must be angry with me." | What else could explain this? What do I actually know? |
6. Catastrophising (catastrophizing) | Jumping to the worst possible outcome | "If I make one mistake at work, I'll lose my job." | What's the most likely outcome? If the worst happened, how would I cope? |
7. Emotional reasoning | Treating a feeling as proof | "I feel anxious, so something bad must be about to happen." | Is this a fact or a feeling? What would the evidence say? |
8. 'Should' and 'must' statements | Rigid rules for yourself or others | "I should always be calm and productive." | Is this rule fair or realistic? What would I prefer, rather than demand? |
9. Labelling | Turning one action into a judgement about who you are | "I forgot her birthday. I'm such an idiot." | Am I describing an action or attacking myself? What's a fairer description? |
10. Personalisation and blame | Taking all the responsibility, or putting all of it on someone else | "My friend seems upset. It must be something I did." | What other factors were involved? What was actually in my control? |
You'll often find two or three distortions tangled together in one thought. "They didn't reply, they're sick of me, I'll end up alone" contains mind reading, fortune telling and catastrophising. You don't need to label them perfectly. A rough label is enough to slow the thought down.
What is catastrophising, and how do I stop it?
Catastrophising (spelled catastrophizing in the US and Canada) is when your mind leaps from a small or uncertain event to the worst possible outcome, and then treats that outcome as likely. A headache becomes a serious illness. A short message from your manager becomes being fired. One awkward comment becomes the end of a friendship. It's closely related to magnification, where problems get blown out of proportion while positives shrink.
NHS Every Mind Matters lists "expecting the worst" as one of the most common unhelpful thinking patterns, and suggests stepping back to ask whether the outcome is really likely and whether there is good evidence for it. You can't always talk yourself out of a catastrophic thought, but you can loosen its grip. These steps help:
Notice the jump. Write down the first event and the worst-case thought separately. Seeing the gap between them is often the first relief.
Rate how likely it is. Ask "how likely is this, really, from 0 to 100?" and then "what's the most likely outcome?"
Plan for the worst, briefly. Ask "if the worst did happen, what would I do?" Most people find they'd cope better than the thought suggests.
Look for the middle. Between best case and worst case, what's a realistic outcome?
Turn it into an action. If there's something useful you can do (send a message, ask a question, prepare), do one small step. If there isn't, note the thought and come back to it later.
Catastrophic thoughts often feel most convincing late at night or when you're tired or stressed. If you notice that pattern, it's worth recording the time and context too.
How do you spot cognitive distortions in your own thinking?
Distortions are hard to see from the inside because they feel like plain facts. A few signs a thought might be distorted:
It contains absolutes like 'always', 'never', 'everyone' or 'nothing'.
It came with a sudden spike of emotion: anxiety, shame, anger or dread.
It predicts the future or claims to know what someone else is thinking.
It's a harsh label about yourself, rather than a description of what happened.
You'd never say it to a friend in the same situation.
The easiest way to catch them is to write the thought down as close to the moment as you can, in the exact words your mind used. By the time you think back hours later, the wording has usually faded into a vague "I was stressed." Our guide on how to track negative thoughts in the moment has practical ways to do this without it taking over your day.
How do you challenge cognitive distortions?
Challenging a distorted thought doesn't mean forcing yourself to be positive. It means checking whether the thought is accurate and helpful, and finding a more balanced version. NHS Every Mind Matters describes a simple approach of catching the thought, checking it and changing it. In practice, that looks like this:
Catch it. Notice the thought and write it down word for word, with what was happening and how you felt.
Name it. Use the table above to label the likely distortion, even if you're not sure.
Check the evidence. What supports the thought? What doesn't? What other explanations are there?
Ask the friend question. What would you say to a friend who had this thought?
Write a balanced alternative. Not the opposite, just a fairer version you can believe.
Re-rate how you feel. Even a small drop in intensity counts.
A structured way to do this is a thought record. NHS Every Mind Matters sets one out in seven steps, from the situation and your first feelings through to evidence for and against, an alternative thought and how you feel now. Our step-by-step guide on how to use a CBT thought record walks through it with a full example.
It's also normal for a balanced thought to feel less convincing than the distorted one at first. NHS Every Mind Matters notes that changing a thought isn't always possible, and that the practice can still help you build flexibility and perspective. Over weeks, you start to catch the pattern earlier.
What does challenging a cognitive distortion look like? A worked example
Here's how one moment might look written down, step by step.
Situation: It's 4pm. I messaged a friend this morning about our plans tonight and she hasn't replied.
Feeling: Anxious, a bit hurt. 75 out of 100.
Thought: "She's annoyed with me. She's going to cancel, and it's because I'm boring to be around."
Distortions: Mind reading ("she's annoyed"), fortune telling ("she's going to cancel"), labelling ("I'm boring"), and a touch of catastrophising.
Evidence for: She usually replies faster. Last month she cancelled once.
Evidence against: She cancelled last month because she was ill and apologised. She told me last week she's swamped at work. She suggested tonight's plans herself.
Balanced thought: "She's probably busy. If she does cancel, it's more likely to be about her week than about me. I can check in later if I need to."
Feeling now: Still a little uneasy, but 35 out of 100.
The goal isn't to feel nothing. It's to stop one unanswered message turning into a story about your worth. If you do this regularly, you'll also start to see which distortions you lean on most, which our guide to spotting patterns in your thinking explores.

Frequently asked questions
What are the most common cognitive distortions?
The ones that come up most often are all-or-nothing thinking, overgeneralisation, mental filtering, discounting the positive, jumping to conclusions (mind reading and fortune telling), catastrophising, emotional reasoning, 'should' statements, labelling and personalisation. Different sources group and name them slightly differently, but the patterns are the same.
How do I stop catastrophising?
Write down the event and the worst-case thought separately, then ask how likely the worst case really is and what the most likely outcome would be. Briefly plan how you'd cope if the worst did happen, and take one small, useful action if there is one. Catastrophic thoughts usually lose some of their power once they're on paper and checked against the evidence.
Can you have more than one cognitive distortion at once?
Yes, and it's very common. A single thought like "they ignored me, I'll end up alone" can include mind reading, fortune telling and catastrophising. You don't need to identify every one. Naming the main pattern is enough to start challenging it.
Do cognitive distortions mean something is wrong with me?
No. Everyone has distorted thoughts sometimes, especially when tired, stressed or low. They become worth working on when they happen often, feel very intense or start to affect your mood, relationships or daily life. If that's happening, talking to a GP, doctor or therapist is a good next step.
Can I challenge cognitive distortions without a therapist?
Many people practise noticing and challenging their thoughts on their own, using tools like a thought record. A therapist can help you go further, especially with deeper beliefs or patterns that feel stuck. If you're struggling, self-help is a useful addition to professional support, not a replacement for it.
MindTrace is not a crisis service and doesn't replace professional care. If you're in crisis or worried about your safety, call or text 988 in Canada or the US, call 999 or Samaritans on 116 123 in the UK, or contact your local emergency services.
