TABLE 2. The R-T-B Taxonomy Based on Pearl’s Causal Inference Hierarchy [31].

The R-T-B causal inference	Graph
I. First order R-T-B
Risk : Risk of event ,Risk(Impact, Probability )
Trust : Trust for event
Bias : Bias of event
II. Second order R-T-B
RiskTrust: – Association : Risk of event given that trust is observed; – Intervention : Risk of event given that we intervene and set the value of trust and sub- sequently observe event ; – Counterfactuals : Risk of event would be observed had been , given that we actually observed to be and trust to be
