GEMS: Error Detection

• Cognitive barriers to error detection.
  
  
• Relevance bias:
  - users cannot consider all evidence;
  - "confirmation bias".
  
  
• Partial explanations:
  - users accept differences between - "theory about state" and evidence.
  
  
• Overlaps:
  - even incorrect views will receive
  - some confirmation from evidence.
  
  
• "Disguise by familliarity".
