Watch for
Your mind jumping to the worst possible outcome first.

Catastrophizing
We imagine worst-case scenarios as likely outcomes.
The tendency to overestimate the probability of catastrophic outcomes and frame decisions around extreme worst-case scenarios rather than expected outcomes.
Why it matters: Central to anxiety disorders particularly generalised anxiety and health anxiety.
Try this
Distinguish between what is possible and what is probable.
Real-world example
A minor headache triggers fear of a brain tumour leading to unnecessary anxiety.
Key researchers
Aaron Beck
First described in 1976
Psychological mechanism
Threat hypervigilance combined with probability neglect. The brains threat detection system amplifies low-probability worst cases by treating what is possible as what is likely.
Seminal research

Below is a realistic scenario. Read it, then choose what you would do. The feedback will show whether a cognitive bias influenced your choice — not to judge, but to reveal the pattern in action.
Thought Experiment
This experiment places you in a realistic decision. Your instinctive choice will reveal whether bias is at work.

Debrief
Catastrophizing is the brains threat system operating without brake. It treats ambiguous situations as dangerous because in ancestral environments assuming the worst was safer. In modern contexts this creates chronic anxiety. The corrective is to distinguish possibility from probability.
