The problems with EDT are quite ordinary... its looking for good news, and also, it is kind of under-specified (e.g. some argue it'd two-box in Newcomb's after learning physics). A decision theory can not be disqualified for giving 'wrong' answer in the hypothetical that 2*2=5 or in the hypothetical that a or not a = false, or in the hypothetical that the decision is simultaneously controlled by the decision theory, and set, without involvement of the decision theory, by the lesion (and a random process if correlation is imperfect).
