Not very many people and certainly very few cryonicists have studied much in the area of sociology, anthropology, sociobiology, evolutionary psychology and other, closely related areas of social science. I have tried to understand these fields of study, and I have found it very helpful in explaining why so few humans have chosen cryonics. I believe, based on my reading of his posts on cryonet, that the poster named Stodolsky has some background in these aforementioned areas of social science. I say that because of how he has responded to my ideas about using religion to promote cryonics. It is strange that so few cryonicists are educated in or interested in these areas of study, because in general, cryonicists are some of the most widely educated people I have ever encountered.
At any rate, these areas of social science show us that humans are for the most part defined by their culture. That statement has many profound consequences.
Almost all aspects of society are tied to culture. Further, humans are not entirely rational outside of certain areas that are defined by their cultures.
We seem to have the idea in our various cultures and in particular in the West, that we are rational, autonomous beings that make our choices in life rationally and freely and independent of any constraints. But this is not true at all. We operate within a rather narrowly defined cultural box. For most of us, our cultural rules define us, and so therefore we cannot go beyond them.
Also, we are not aware of this confinement. There is also a cultural constraint on our being able to acknowledge that our choices are defined by our culture. And that culture does not include cryonics. In fact, cryonics as it currently exists and as it is currently perceived violates fundamental tenets of all cultures.
Going back to your situation with the science fiction writers, your problem with their lack of acceptance and their inability to come to terms with the idea of cryonics and its basic logic really goes right to the heart of our failure to use the ideas found in sociology, anthropology, evo psych, sociobiology, etc., in trying to promote cryonics. Further, although the relevant ideas from those fields of social science may indeed be familiar to you and other cryonicists and other educated people, real-world application of these abstract concepts is another matter entirely. That application is rarely to be found, other than in some few books and academic papers.
I suppose that the bottom line here is that progress with cryonics will likely come from our study of those areas of social sciences and the application of the ideas from those areas of study.
Good luck with all that!
