Mid-2017, I started to examine my reasons for thinking causality is a necessary ingredient in decision theory. I found grounds to reject all the arguments which had previously seemed to speak in favor of CDT, while at the same time, finding that EDT didn't always do what people claimed it did in problems like Newcomb. I began to develop arguments that CDT and EDT were, in the cases which (I claimed) should be of primary interest, the same decision theory.
