 In one sense, this question should be seen as stipulative; the models come from humans, not gods. It is for us to say what they do and do not represent. Nonetheless, we should take care that our stipulations don’t undermine the purposes for which the models were designed, nor the use to which they are standardly put. Insofar as they are meant to capture the notion of influence which appears in causal claims like “how much I water my plant influences how tall it grows”, and insofar as they are meant to forge connections between influence and counterfactuals—or influence and and token causation, or influence and control, or influence and chance—not just any stipulations will serve our purposes. Whether these connections are plausible or defensible will depend upon how we understand the models; what we take them to be saying about the world.
