Cognitive Distortion
Definition
A cognitive distortion is an inaccurate or illogical thought that misrepresents reality. Common examples include:
- Catastrophising: “I made one mistake; my whole career is ruined”
- All-or-nothing thinking: “If I’m not perfect, I’m a total failure”
- Mind-reading: “They think I’m stupid” (without evidence)
- Overgeneralisation: “This always happens to me”
- Personalisation: “It’s my fault that traffic was bad”
Cognitive distortions are inferences or perceptions that deviate from what is actually true or logical.
Key Distinction: Cognitive Distortion vs. Irrational Belief
This distinction is important in REBT:
| Cognitive Distortion | Irrational Belief |
|---|---|
| Inaccurate perception of reality | Evaluative judgment about reality (accurate or not) |
| Example: “Nobody likes me” when evidence suggests people do | Example: “I must be liked by everyone, and if I’m not, it’s awful” |
| Focus: What is true? | Focus: How is it to be evaluated? |
| Addressed by: Evidence-testing, reality-checking | Addressed by: Disputation of the logical/philosophical claim |
A client may have an accurate perception (“My partner was angry”) but an irrational belief about it (“This means I’m worthless”). Conversely, they may have an inaccurate perception (“Nobody likes me”) that reflects an underlying irrational belief (demandingness that leads to filtering out positive evidence).
Clinical Relevance
Understanding this distinction helps the therapist work more effectively:
- If a client’s thought is inaccurate, Socratic questioning or behavioral experiments may help reality-test it
- If a client’s thought is accurate (or becomes accurate after evidence-testing), the focus shifts to the underlying evaluative belief
- A client may need to shift from “This bad thing happened” (reality) to “I can cope with and learn from this bad thing” (rational belief about the reality)
How Different Frameworks Address This
| Framework | Approach |
|---|---|
| CBT | Identifies and challenges cognitive distortions through evidence and behavioral experiments; may focus less on core philosophical beliefs |
| REBT | Distinguishes distortions from irrational beliefs; works primarily on the evaluative/imperative beliefs that may underlie or be separate from distortions |
| ACT | Does not primarily aim to correct distortions; instead teaches defusion (changing relationship to thoughts) and values-based action |
The Ten Common Distortions (Burns)
David Burns identifies ten of the most common cognitive distortions in Feeling Great. As he notes: “Cognitive distortions aren’t truthful realism—they’re one of the world’s oldest cons. Your thoughts are often biased and inaccurate, and that’s where your emotional pain comes from.”
- All-or-Nothing-Thinking — viewing things in absolute black-and-white categories
- Overgeneralization — treating a single failure as a never-ending pattern
- Mental Filtering — filtering out positives and focusing entirely on negatives
- Discounting the Positive — telling yourself positive qualities don’t count
- Fortune-Telling — making arbitrary negative predictions about the future
- Mind Reading — jumping to conclusions about how others think without evidence
- Magnification-and-Minimization — exaggerating the negative, minimizing the positive
- Emotional-Reasoning — reasoning from how you feel (“I feel hopeless, so things are hopeless”)
- Should-Statements — criticizing yourself or others with rigid imperatives
- Labeling — capturing a person (yourself or others) with a single negative label
