Compare it to other non-evidence-based “medical” procedures such as homeopathy of prayer-based healing.
Okay—I pay some attention to the skeptical community, such as the podcasts “The Skeptic’s Guide to the Universe” and “Skeptoid”. The two items you mention not only have no significant evidence for their efficacy, they have significant quantities of evidence against it, plus additional, even stronger, evidence against their claimed methods of operation. Thus, there is plenty of evidence to tot up, dragging the amount of confidence that anyone should have in those procedures to be in the minus dozens of decibans—say, −70 or below.
The most pessimistic estimate given on that page for successful cryonic revival is around 1/1000, or −30 decibans.
That’s a minimum difference in confidence of 40 decibans—the equivalent of changing your mind from a 50⁄50 chance to 99.99% certainty. Or from 99.99% certainty of falsehood to a 50⁄50 chance. Or, put another way, at least two completely independent studies each with a p-value of 0.01 or better.
My conclusion: there’s very little comparison between cryonics and pseudoscience.
