Cognitive Distortions: The Lies Your Brain Tells You (And How to Challenge Them)

Your brain is not always telling the truth. Cognitive distortions are systematic patterns of negative thinking that fuel anxiety and depression.

What Are Cognitive Distortions?

Cognitive distortions are irrational, negatively biased patterns of thinking identified by psychiatrist Aaron Beck, the founder of Cognitive Behavioural Therapy (CBT). They are mental filters or lenses that warp our perception of reality, causing us to misinterpret events in consistently negative ways. Everyone experiences them, but for people with anxiety and depression, they become automatic and overwhelming.

Common Distortions You May Recognize

All-or-Nothing Thinking: "I failed one thing, so I am a complete failure." Catastrophizing: "I made a mistake at work — I will definitely get fired." Mind Reading: "She didn't respond to my message — she must be angry with me." Personalization: "They seem upset; it must be something I did." Recognizing these patterns by name is the first step to loosening their grip.

The CBT Technique: Thought Challenging

When you catch a distorted thought, apply the "Courtroom" technique. Put the thought on trial. Evidence for: what facts support this thought? Evidence against: what contradicts it? What would I tell a friend who had this thought? What is a more balanced, realistic alternative? This structured questioning helps your brain develop new, more accurate thinking habits over time.

Your feelings are valid, but your thoughts are not always facts. Question them.
