The premises of Pascal's wager are normally presented as abstract facts about the universe - there happens to (maybe) be a god, who happens to have set up the afterlife for the suffering of unbelievers.
But, assuming we ever manage to distinguish trade from extortion, this seems a situation of classical extortion. So if god follows a timeless decision theory - and what other kind of decision theory would it follow? - the correct answer would seem to be to reject the whole deal out of hand, even if you assume god exists.
Or, in other words, respond to a god that offers you heaven, but ignore one that threatens you with hell.
One problem with this is that the "abstract facts" interpretation is actually more reasonable than the idea that a good God exists and threatens to torture some people for eternity. This is why modern Christians themselves tend more towards the abstract fact interpretation of hell, and are less willing to talk about it in terms of punishment.
In the future, as it becomes more and more clear how much determination of our actions comes from our brains, Christianity will move even more in this direction. That is more reasonable than the opposite, and so it is also a more reasonable interpretation when you are considering the wager.
There is another factor here too. Calling the threat "extortion" implies that such a threat would be evil. I agree that it would be, as a matter of fact, but someone considering the probability that "a revealed religion is true" should not be considering "a revealed religion is true, and God is evil," but "a revealed religion is true, and God is good despite all appearances." Obviously the claim that God is good is an essential part of basically every purportedly revealed religion, so if you consider the hypothesis that God is evil, you are not considering the possibility of those religions at all. So the only way of actually considering the hypothesis implies the denial that the threat counts as extortion.
Doesn't seem so obvious to me. I suspect that "God is good" is an invention of the recent few thousand years. Previously, gods were simply supernatural beings, doing some random things, sometimes threatening people "I will punish you if you do X" or offering them trade "if you do X, I will (maybe) give you Y".
Even the relatively recent Gods often seem only "good" in the sense "yeah, he does some unpleasan... (read more)
