Which seems to give me just as much control[4] over the past as I have over the future.
And the footnote:
whatever I can do to make my world the one with FA in it, I can do to make my world the one with HA in it.
This is only trivially true in the sense of saying “whatever I can do to arrive at McDonalds, I can do to make my world the one where I walked in the direction of McDonalds”. This is ordinary reality and nothing to be “bothered” by—which obviates the original question’s apparent presupposition that something weird is going on.
If there’s something incoherent or contradictory about “either the propositions ‘HA happened, A is the current state, I will choose CA, FA will happen’ are all true, or the propositions ‘HB happened, B is the current state, I will choose CB, FB will happen’ are all true; the ones that aren’t all true are all false”, can you be specific about what it is?
It’s fine so long as HA/A and HB/B are understood to be the events and states during the actual decision-making process, and not referencing anything before that point, i.e.:
H → S → (HA ->A) → CA → FA
H → S → (HB ->B) → CB → FB
Think of H as events happening in the world, then written onto a read-only SD card labeled “S”. At this moment, the contents of S are already fixed. S is then fed into a device which will then operate upon the data and reveal its interpretation of the data by outputting the text “A” or “B”. The history of events occurring inside the device will be different according to whatever the content of the SD card was, but the content of the card isn’t “revealed” or “chosen” or “controlled” by this process.
How is ‘revealing something about the past’ retrocausal?
It isn’t; but neither is it actually revealing anything about the past that couldn’t have been ascertained prior to executing the decision procedure or in parallel with it. The decision procedure can only “reveal” the process and results of the decision procedure itself, since that process and result were not present in the history and state of the world before the procedure began.
I don’t know how to clarify this, because I don’t understand why you think I am. I do think we can narrow down a ‘moment of decision’ if we want to, meaning e.g. the point in time where the agent becomes conscious of which action they will take, or when something that looks to us like a point of no return is reached. But obviously the decision process is a process, and I don’t get why you think I don’t understand or have failed to account for this.
Here is the relevant text from your original post:
State A: Past events HA have happened, current state of the world is A, I will choose CA, future FA will happen.
State B: Past events HB have happened, current state of the world is B, I will choose CB, future FB will happen.
These definitions clearly state “I will choose”—i.e., the decision process has not yet begun. But if the decision process hasn’t yet begun, then there is only one world-state, and thus it is meaningless to give that single state two names (HA/A and HB/B).
Before you choose, you can literally examine any aspect of the current world-state that you like and confirm it to your heart’s content. You already know which events have happened and what the state of the world is, so there can’t be two such states, and your choice does not “reveal” anything about the world-state that existed prior to the start of the decision process.
This is why I’m describing HA/A and HB/B in your post as incoherent, and assuming that this description must be based on an instantaneous, outside-reality concept of “choice”, which seems to be the only way the stated model can make any sense (even in its own terms).
In contrast, if you label every point of the timeline as to what is happening, the only logically coherent timeline is H → S → ( H[A/B] → A/B ) → C[A/B] → F[A/B] -- where it’s obvious that this is just reality as normal, where the decision procedure neither “chooses” nor “reveals” anything about the history of the world prior to its beginning execution. (IOW, it can only “reveal” or “choose” or “control” the present and future, not the past.)
But if you were using that interpretation, then your original question appears to have no meaning: what would it mean to be bothered that the restaurant you eat at today will “reveal” which way you flipped the coin you used to decide?
