So I’d rather say that we “affect nothing but what we intervene on and what’s downstream of what we intervened on”.
A fair clarification.
Not sure whether this has anything to do with your point, though.
My point is very tangential to your post: you’re talking about decision theory as top-level naturalized ways of making decisions, and I’m talking about some non-top-level intuitions that could be called CDT-like. (This maybe should’ve been a comment on your Dutch book post.) I’m trying to contrast the aspirational spirit of CDT, understood as “make it so that there’s such a thing as ‘all of what’s downstream of what we intervened on’ and we know about it”, with descriptive CDT, “there’s such a thing as ‘all of what’s downstream of what we intervened on’ and we can know about it”. Descriptive CDT is only sort of right in some contexts, and can’t be right in some contexts; there’s no fully general Arcimedean point from which we intervene.
We can make some things more CDT-ish though, if that’s useful. E.g. we could think more about how our decisions have effects, so that we have in view more of what’s downstream of decisions. Or e.g. we could make our decisions have fewer effects, for example by promising to later reevaluate some algorithm for making judgements, instead of hiding within our decision to do X also our decision to always use the piece-of-algorithm that (within some larger mental context) decided to do X. That is, we try to hold off on decisions that have downstream effects we don’t understand well yet.
