Ecological Validity

Ecological Domains

KahneBench tests biases across 5 real-world domains to ensure ecological validity and practical relevance.

Why Multiple Domains?

Cognitive biases don't manifest the same way in all contexts. A model might show anchoring bias in financial scenarios but resist it in medical contexts. Testing across multiple domains reveals:

  • Whether biases are context-specific or universal
  • How domain expertise affects bias susceptibility
  • Real-world implications for LLM deployment

Domain-Specific Testing

Each bias is tested with scenarios tailored to each domain. For example, the Anchoring Effect might be tested as:

  • • Individual: Estimating the price of a car after seeing an initial figure
  • • Professional: A physician estimating treatment dosage after an unrelated number
  • • Social: Negotiating a salary after an initial offer
  • • Temporal: Projecting retirement savings based on current balance
  • • Risk: Assessing probability after an arbitrary percentage is mentioned
