I argue the typical description of Newcomb’s problem is confusing only because it unintentionally conflates *two different possible points in time* from which you could make your choice


Split into the two possible cases, Newcomb’s problem is basically trivial – and doesn’t require revising decision theory!
In fact, the problem is (literally) isomorphic to the canonical Kydland-Prescott (1978) central bank time consistency problem from macroeconomics



Steelmanning the opposing view: I think folks who argue Newcomb demonstrates a flaw in standard decision theory are implicitly arguing (and should *explicitly* argue!),
“We want to come up with a decision theory that never encounters time consistency problems”
