The 10 Cognitive Distortions, With Examples

A cognitive distortion is a habit of thought that feels like an observation. It arrives fully formed, in your own voice, with the weight of a fact — "I always ruin things" — and because it sounds like you, you rarely stop to check it.

Cognitive behavioural therapy's contribution was to notice that these habits come in a small number of recognisable shapes. Aaron Beck catalogued them in the 1960s while treating depression; David Burns popularised the list in Feeling Good (1980). Ten of them cover most of what your mind does to you on a bad day.

Naming the shape is most of the work. A thought you can label is a thought you can argue with.

1. All-or-nothing thinking

Also called black-and-white or polarised thinking. There are two boxes — success and failure — and no room between them. One missed run makes you someone who doesn't exercise. One awkward sentence makes the whole dinner a disaster.

The question that breaks it: if this were a percentage instead of a verdict, what number would it be? Almost nothing in a life is 0 or 100.

2. Overgeneralisation

One event becomes a rule. The tell is the vocabulary: always, never, everyone, nothing. A single rejection stops being a thing that happened and becomes a description of how things go.

The question: how many times, exactly? Count. If the honest number is three out of fifteen, "always" is a lie you told yourself.

3. Mental filter

You pick out one negative detail and dwell on it until the whole picture darkens — like a drop of ink in a glass of water. Nine parts of the presentation landed. You are replaying the tenth.

The question: what else was in the room that I'm not counting?

4. Discounting the positive

The close relative of the mental filter, and meaner. Here the good things register — you just disqualify them. Praise was politeness. The win was luck. The effort doesn't count because it should have been easier.

The question: if a friend told me this about their own week, would I accept the same explanation?

5. Jumping to conclusions

Reading the situation without the data. It splits into two familiar moves:

Mind reading

Deciding you know what someone thinks of you, and treating the guess as reported speech.

Fortune telling

Predicting the outcome, then reacting to the prediction as though it already happened.

The question: what would I need to see for this to be true — and have I seen it?

6. Magnification and minimisation

The volume knob. Your mistakes get turned up until they fill the room; your strengths get turned down until they're inaudible. Someone else's identical mistake, of course, gets handled at normal volume.

The question: what weight would I give this if a colleague had done it?

7. Emotional reasoning

Treating a feeling as evidence. I feel like a fraud, therefore I am one. The logic is circular, but it's fast, and feelings are persuasive because they're happening inside you.

The question: is this a fact about the world, or a fact about how I feel right now? Both can be real. Only one is evidence.

8. "Should" statements

A private rulebook nobody agreed to, enforced with guilt. Aimed inward it produces shame; aimed outward it produces resentment when other people fail to follow rules they never read.

The question: who wrote this rule, and would I apply it to anyone else? Try swapping should for I'd prefer to and see whether the sentence survives.

9. Labelling

Overgeneralisation applied to a person instead of an event. You don't say "I made a mistake" — you say "I'm an idiot." The label converts a thing you did into a thing you are, which is much harder to change.

The question: what specifically happened? Describe the behaviour, not the person. "I missed the deadline" is workable. "I'm a failure" is not.

10. Personalisation and blame

Taking responsibility for events you didn't control — a partner's mood, a team's slipping deadline, someone else's bad day — or, in reverse, assigning all of it elsewhere and none of it to yourself.

The question: list every factor that contributed, then give each a share of the total. Your slice is usually real, and usually smaller than the one you assigned yourself.

What to do once you've named one

Naming the distortion is step one, not the finish. The distorted thought loses its authority when you replace it with something more accurate — not more positive, more accurate.

Notice that the balanced version isn't cheerful. It doesn't claim the presentation was brilliant. It's just what a fair witness would have said — and a fair witness is exactly what a distorted thought lacks.

The formal version of this exercise is the thought record, and it's worth learning properly: how to write a CBT thought record.

A note on limits

Spotting distortions is a skill, and like any skill it's clumsy before it's automatic. Expect to catch them hours late at first, then minutes, then as they form. That progression is the whole point of daily practice.

This is also self-help, not treatment. CBT delivered by a trained therapist has decades of trial evidence behind it for depression and anxiety; reading a list of distortions is a smaller thing. If your mood is severe, persistent, or getting worse, work with a professional. If you're in crisis, contact your local emergency service or a crisis line.
