The greater the number of cases in the cumulative experience, the higher the degree of probability in the conclusion. The various instances of fact A and legal consequence B are called confirming instances of the causal relationship between fact A and legal consequence B. The greater number of confirming instances, the higher the probability of the conclusion.
