Can we directly observe the true causal Rd?

Counterfactuals. Why is it not possible to directly observe a causal contrast? Because at least one of the disease-frequency parameters needed for a causal contrast, R1 and R0, must be counterfactual and therefore unobservable. R1 is an actual disease frequency; it occurs, and therefore it can be observed.

What makes a causal relationship?
