First, I should point out that I don't believe the choices about how to increase success for cryonics are binary, as you lay them out above. While I don't use the same language you do, my argument has been that it is not possible to get people to freely adopt cryonics in larger numbers, unless you change them, as opposed to trying to change cryonics, or how it is "marketed."

You use the words "raising people's sanity level" to describe the change you believe is necessary, before they are able to choose cryonics rationally. The dictionary definition of sanity is: "The ability to think and behave in a normal and rational manner; sound mental health." I don't know if that is the definition you are using, or not?

Depending upon how you define "rational," "normal," and "sound mental health," we may be on the same page. I would say that most people currently operate with either contra-survival values, or effectively no values. Values are the core behavioral imperatives that individuals use in furtherance of their survival and their well being. It is easy to mistake these as being all about the individual, but in fact, they necessarily involve the whole community of individuals, because it is not (currently) possible for individual humans to survive without interaction with others. Beyond these baby steps at explanation, there is a lot that must be said, but clearly, not here and not now. What I've said here isn't meant to be rigorous and complete, but rather to be exemplary of the position I hold (and that you asked me about).

It is also the case that not everyone has the biological machinery to make decisions at a very high level of thought or reasoning. And amongst those who do, arguably, few do so much of the time, especially in terms of epistemological questions (and none of us do it all of the time). That's in part what culture is for. If we considered every decision in penultimate detail, we'd never get anything done. If the culture is bankrupt, then the situation is very bad, not just for survival of the individual, but for the civilization as a whole. So, you either fix that problem, or you don't succeed with cryonics. Put another way, the failure of this culture to embrace cryonics and life extension is a symptom of the problem, rather than the primary problem itself. -- Mike Darwin
