Cryonics sounds strange and not-of-our-tribe and they don't see other people doing it, a feeling expressed in words as "weird". It's perceptually categorized as similar to religions or other scams they've heard about from the newspaper, based purely on surface features and without any reference to, or remediability by, the strength of the underlying logic; that's never checked
If you want people to sign up for cryonics, the method with by far the strongest conversion ratio is to train them from scratch in advanced sanity techniques.
The implication of the latter quote is that the sanity techniques are being applied, and cryonics is being signed up for largely because of its merits.
I think that the former quote captures more of what is going on. A community is being created in which cryonics isn't as weird, removing previous barriers without implicating rationality directly.
I have a testable prediction that can partially parse out at least one factor. One disproportionately powerful influence on human beings in addition to (and mutually reinforcing) group think/behavior is accepting authority. (It is true that what others do is valid evidence for the validity of what they are doing, and is greater evidence the more the other(s) resemble(s) (an) optimal reasoning system(s) and is/are informed,)
I predict that if/as it becomes better known that Eliezer Yudkowsky signed up with the Cryonics Institute and not Alcor, the ratio of people signing up with Alcor and citing LW/HPATMOR to the people signing up with the Cryonics Institute and citing LW/HPATMOR will decrease.
"I think that the former quote captures more of what is going on. A community is being created in which cryonics isn't as weird, removing previous barriers without implicating rationality directly."
Very much so. People don't actually believe in the future.
