I wrote a blog post arguing that people sign up for cryo more for peace of mind than for immortality. This suggests that cryo organizations should market towards the former desire than the latter (you can think of it as marketing to near mode rather than far mode, in Hansonian terms).
Perhaps we've been selling cryonics wrong. I'm signed up and feel like the reason I should have for signing up is that cryonics buys me a small, but non-zero chance at living forever. However, for years this should didn't actually result in me signing up. Recently, though, after being made aware of this dissonance between my words and actions, I finally signed up. I'm now very glad that I did. But it's not because I now have a shot at everlasting life.

For those signed up already, does peace-of-mind resonate as a benefit of your membership?
If you are not a cryonics member, what would make you decide that it is a good idea?
Would you reconsider if you saw successful revival of a small organism? C. Elegans? A mouse?
C. Elegans can be already cryopreserved and revived, mice can't.
Keep in mind that any success on small organism doesn't necessarily translate to larger organisms due to the square-cube law: the heat capacity of an organism, or its brain, is proportional to its volume, while the speed at which you can cool it for a given temperature difference is proportional to its surface.
If the temperature difference between the inside and the outside is too high, the outer layers freeze/vitrify and contract before the inner layers, causing cracking. If the cooling speed... (read more)
