True, in the positive/negative dichotomy it is a Pascal's Wager.

Probably what makes the sell harder for cryonics is that it promises not an infinitely good future but merely one of uncertain quality, though one that it is possible to hypothesise about based on well-discussed inferences from the very fact you were woken up.

As things stand right now I have to admit it's hard to see where you would get a big jump in takeup, because it seems conceded that the science is a very long way away and thus the probability of it working will not appear to rise for a very long time, and also the impression of a future world where it does work will probably remain roughly constant for the same reason of the time gap. As these two factors seem to be the biggest factors in a decision, they seem too inert for cryogenics' liking.

Any ideas of a "game changer" that would persuade people that it were as natural a thing to plan as making a will, buying life insurance or having a donor card?
