The falsification for the applicability of Bayesian causal map applying to the system decision

This article describes the use of causal map and the Bayesian network diagram, analyzes the applicability of the two tools. The paper proposes the building of Bayesian causal map (BCM). That is the application of Bayesian network in causal map proposed by some scholars at home and abroad. This paper analyzes the applicability of the Bayesian causal map. Demonstrate the contradictions that it can not be resolved through examples. The paper concluded that the Bayesian Causal Map is not an effective tool for probability reasoning, Bayesian networks used in conjunction with the causal map is not meaningful.
