I’m not sure the “objective/subjective” division quite fits, though. Of course questions of values do come into cause-effectiveness, but I also think there are a lot of questions about matters which are in theory objective, although in practice very difficult to be sure about (for instance “will health or education lead to more economic growth?”).
Good point—if you just list the effectiveness of a bunch of causes (C1, C2, C3, etc.) the shared downstream effects (like your example of economic growth) probably make them non-independent, unless you have very unusual values.
