So, to you, all "anomalous" information is ESP?
Imaging that you had no idea what electricity was. Would a lightbulb constitute ESP, then? By your definition, it would.
Anomalous cognition to be precise. Yes it is conceivable there is a physical mechanism. On the other hand, I think this is normally regarded as being somewhat unlikely. For example, research suggests something like telepathy is unaffected by distance, where as with any physical influence, the influence diminishes to the inverse square of the distance concerned.
Not that this is really relevant. My understanding is that ESP is simply defined as anomalous cognition ie a person gaining information though unknown means. ESP does not rule out some sort of physical mechanism, it's just that a physical mechanism is difficult to reconcile with the "signal" being unimpaired by distance or any shielding. Of course, if there is some unknown artifact skewing the results of parapsychological research, then this would not be ESP.

How do you know that?
I read it somewhere. But apart from what Popper thinks, it would be very difficult to justify that it should apply to metaphysical hypotheses. We can appreciate why scientific theories, which are unfalsifiable, might be vacuous, it is more difficult to justify this with metaphysical hypotheses. But in any case, the issue of survival is clearly not vacuous. Either we survive our bodies or we don't! There must be a definite answer to that question, even under the scenario where we lose our individuality after death.

Besides which, in as much as the transmission theory is unfalsifiable, so is the generative theory. Anyway, the survival hypothesis is not compatible with all possible states of affairs because one can disprove it by dying and ceasing to exist!

Aha. So you can never determine whether it is true or false.
Whilst we are still alive? It would be difficult although I wouldn't say impossible. Outside deductive logic, to prove something beyond all doubt is incredibly difficult. Within science, for example, "falsified" theories can most often, if not always, be saved by the introduction of
ad hoc auxiliary hypotheses. I think on the whole it might be useful at this time just to satisfy ourselves with weighing up the various types of evidence for each of the hypotheses (the generative hypothesis or transmission hypothesis), and thereby coming to a rational conclusion as to which hypothesis best explains all the relevant facts.
