 Christopher Hitchcock (1996) holds that an agent should pretend that her act is free of causal influence. Doing this makes partitions of states yielding probabilities for decision agree with partitions of states yielding probabilities defining causal relevance. As a result, probabilities in causal decision theory may form a foundation for probabilities in the probabilistic theory of causation. Causal decision theory, in particular, the version using dependency hypotheses, grounds theories of probabilistic causation.
