 Spohn determines the difference between the ranks \(\kappa(\neg E \mid C \cap F)\) and \(\kappa( E\mid C \cap F)\) by the difference in the number of violations of causal regularities between the world where \(\neg E \land C \land F\) is true and the world where \(E \land C \land F\) is true. In the former world, the causal regularity between \(C\) and \(E\) is violated, while the causal regularity between \(C\) and \(F\) is respected. No causal regularity is violated in the world where \(E \land C \land F\) is true. Hence,
