> If you were to stop all of those things, you could surely stop the rain as well. By the way, this is not true in general. Suppose B…F are sampled from Boolean variables with bias 0.5. A Boolean circuit like A = (sum(B,C,D,E,F)>3) + (not B and not C and… not F). A is correlated with all of its causes B through F. However, stopping all of its causes, causes A to turn on. > If you were to stop all of those things, you could surely stop the rain as well. But, you typically can't intervene everywhere. For example, you may not have any power over the gardener who normally turns the sprinkler on. The point of interventions (like turning a sprinkler on) is that you can reason about what would happen.
