title: Opposite repertory-rubrics in Bayesian perspective.
abstract: BACKGROUND
  Hitherto entries have been added to a rubric in the repertory when patients responding well to a specific medicine showed the corresponding symptom. Continuing like this, theoretically every medicine will eventually appear in every rubric.
  
  
  METHODS
  This becomes clear if we compare opposite symptom-rubrics. Polarity Analysis (PA) subtracts opposite rubrics and has been shown to improve clinical results.
  
  
  CONCLUSIONS
  The source of this problem and the reason for the success of PA are clear from Bayesian perspective. A reliable repertory should be based on Bayesian principles.
