Cognitive distortions

Systematically inaccurate thinking patterns that occur in everyone but multiply in anxiety and depression. Not errors of logic — shortcuts that misfire.

The concept comes from Aaron Beck, the founder of cognitive therapy, and is the backbone of CBT. The basic idea: the mind uses shortcuts to process quickly, and under emotional load those shortcuts systematise in the direction of the mood.

The commonest:

  • All-or-nothing thinking — total success or total failure, nothing between.
  • Overgeneralisation — one event becomes "always" or "never".
  • Mind reading — you assume what the other person thinks and act as if you knew.
  • Catastrophising — jumping to the worst outcome and treating it as the likeliest.
  • Personalisation — assuming someone's reaction is about you.
  • Filtering — retaining only the negative element of a whole.
  • Emotional reasoning — "it feels true, therefore it is true."

The work isn't labelling them correctly but testing them: what evidence exists, what equally plausible alternative exists, what actually happened last time.

What it is confused with

It gets confused with negative thinking in general, but distortions can be positive too — unrealistic optimism is also a distortion. It is also confused with being right: if the thought "I'm going to be fired" has real evidence behind it, that isn't a distortion but an accurate appraisal, and therapy then moves to "all right, and if it happens, what's the plan?". The criterion isn't how unpleasant the thought is, but how accurate.
