Domain Neglect Bias – when you ignore relevant knowledge from other fields

Electric editorial collage illustrating Domain Neglect Bias

Do you think you can run a business without understanding human psychology? That’s Domain Neglect Bias – the tendency to ignore relevant knowledge from other fields when solving complex problems.

Where it can show up


- Business – launching a product without marketing, assuming a good product sells itself.
- Medicine – a doctor focuses only on symptoms, ignoring lifestyle factors.
- IT & Security – an engineer designs a secure system but forgets that users won’t follow complicated rules.

A practical countermeasure


- Think beyond your field – complex problems require interdisciplinary knowledge.
- Don’t dismiss related disciplines – every field offers valuable insights.
- Seek input from experts in other areas – sometimes, your problem has already been solved elsewhere.
