One can easily think of mundane situations in which A has to decide on some action without knowing whether or not B has or has not already made some decision, and in which how A acts will affect what B decides, if B has not already made their decision. I don’t think such mundane problems pose any sort of problem for causal decision theory. So why would Newcomb’s Problem be different?
