What Are Cognitive Distortions?

What are cognitive distortions?

“Cognitive distortion” is a common term for a thought pattern that interprets information in a biased or incomplete way. NHS resources often use the more everyday phrase unhelpful thinking styles. These patterns may happen quickly and automatically, which is why they can be difficult to notice in the moment.

Cognitive behavioural therapy looks at the links between thoughts, feelings, and behaviours. If an automatic thought intensifies an emotion or leads to avoidance, examining that thought can create room for a different response.

The aim is not forced positivity. A balanced thought can still acknowledge uncertainty, disappointment, risk, or pain. It just tries to include the evidence your first thought may have missed.

Why do unhelpful thoughts feel so convincing?

Automatic thoughts often arrive as short conclusions rather than carefully tested ideas: “I will fail,” “They think I am awkward,” or “This always happens.” Because the thought and the emotional reaction appear close together, the feeling can seem like proof that the thought is true.

Labelling a pattern is not about arguing with yourself. It is a prompt to slow down, separate facts from interpretations, and consider what else could be true.

10 common cognitive distortions—with examples

1. All-or-nothing thinking

You see only two categories—success or failure, perfect or terrible—when the situation has shades of grey.

Example: “I missed one workout, so I have completely failed at building a routine.”

Question to ask: What would a middle-ground description sound like?

2. Catastrophising

You predict the worst possible outcome and treat it as likely or unbearable.

Example: “I made a mistake in this email. I will lose my job.”

Question to ask: What is the most likely outcome, and how could I cope if something went wrong?

3. Mind reading

You assume you know what another person thinks without enough evidence.

Example: “They were quiet at lunch, so they must be annoyed with me.”

Question to ask: What other explanations could fit their behaviour?

4. Fortune telling

You predict that something will go badly and treat the prediction as a fact.

Example: “There is no point applying. I already know they will reject me.”

Question to ask: Am I describing what has happened or predicting what might happen?

5. Mental filter

You focus on one negative detail while overlooking the wider picture.

Example: “One person criticised my presentation, so it went badly”—despite several positive responses.

Question to ask: What information am I filtering out?

6. Discounting the positive

You dismiss positive experiences or qualities as luck, politeness, or something that “does not count.”

Example: “The client only praised my work because they were being nice.”

Question to ask: If the positive evidence were about a friend, would I dismiss it?

7. Overgeneralisation

You turn one experience into a broad rule, often using words such as “always” or “never.”

Example: “That date felt awkward. I will never be comfortable meeting new people.”

Question to ask: Is this one event, or a rule with no exceptions?

8. Emotional reasoning

You treat a feeling as evidence that a conclusion is true.

Example: “I feel unprepared, so I must be incapable.”

Question to ask: What are the observable facts, separate from how I feel?

9. “Should” statements

You apply rigid expectations to yourself or others, creating guilt, pressure, or frustration.

Example: “I should never feel nervous when speaking in public.”

Question to ask: Could I replace “should” with a flexible preference or realistic goal?

10. Personalisation and self-blame

You take too much responsibility for an outcome that had several possible causes.

Example: “The group was quiet because I made the evening boring.”

Question to ask: What other people, circumstances, or factors may have contributed?

How to challenge an unhelpful thought

The NHS describes a simple “catch it, check it, change it” approach. You can expand it into five practical steps:

1. Catch the thought. Write the exact words or image that appeared in your mind.
2. Name the pattern. Ask whether one of the styles above describes what the thought is doing.
3. Check the evidence. List facts that support the thought and facts or context it has left out.
4. Write a balanced thought. Create a realistic response that considers both sides.
5. Re-rate the feeling. Notice whether its intensity changed, even slightly, and choose a useful next step.

A structured CBT thought record gives you space to work through these steps. If you are new to structured reflection, our guide to starting a CBT journal may also help.

A fictional worked example

This example is invented for education. It shows how the pattern label can open a question rather than end the conversation.

When a thinking-pattern label is not helpful

Do not use a label to dismiss a genuine concern, invalidate an emotion, or tell someone that an experience is “all in their head.” Sometimes the available evidence really does point to a problem that needs action.

The useful question is not “Is this thought bad?” but “Is this thought accurate, complete, and helpful enough for deciding what to do next?” If thoughts or emotions are persistent, overwhelming, or affecting daily life, consider speaking with a qualified mental-health professional.
