According to the survivalist interpretation of mediumship, the existence of discarnate persons provides the best explanation for the data associated with physical and mental mediumship. Others—advocates of what is often called the “super-psi hypothesis”—maintain that the data of mediumship may be at least equally explained in terms of living agent psi (ESP and psychokinesis). Many defenders of the survivalist interpretation of mediumship attempt to defl ate the alleged explanatory virtues of the super-psi hypothesis by arguing that the hypothesis is unfalsifi (...) able and lacks independent evidential support. My central contention in this paper is that these frequently encountered survivalist criticisms of the super-psi hypothesis are ultimately self-defeating to the case for survival from mediumship. To show this I first argue in some detail that the survivalist interpretation of mediumship is committed to a kind or degree of psi that is indistinguishable from what is required by the super-psi hypothesis. From this vantage point it can be shown that any attempt to impugn the explanatory virtues of the super-psi hypothesis on account of the kind or degree of psi it requires undercuts the argument for survival itself.
