Q

what is the difference between cognitive and emotional biases?

A
  1. Cognitive errors are based on faulty reasoning (information processing, memory errors, statistical), whereas emotion biases stem from impulses and intuition
  2. Cognitive errors can be moderated through education - they are simply blind spots. Emotional errors are spontaneous and can only be corrected by recognizing and adapting.
