Although the hellish world scenario seems unlikely it might be important to consider. At least according to my own values things like being confined to children's books and being injected with heroin would contribute very little negative utility (if negative at all) compared to even 1 in 1000 of enduring the worst psychologically possible torture for, say, a billion years.
Interesting. Do you have a source on that?
No videocalls - what about the widespread skyping?
You can get some 5.2GB free with dropbox - first they have a few small"quests" giving 0.2 extra. But then they also gave you up to 3GB more if you synced photos from mobile to dropbox (did this then removed the photos to get extra non-picture storage space).
That there is reason to believe that it is "relatively easy" (say if we survive x-risk and get a good singleton within a million years) to colonize billions of galaxies. That makes the expected (ignoring possibility of discovering new useful physics, creating universes etc) hedonic utility of x-risk reduction up to some 9-orders of magnitude greater than I had previously thought.
Why it just something which made it easier to "alieve" (in contrast to just believing) in a singularity, or do you think this information was good evidence for updating towards that a singularity is more likely? (eg because it shows that billionaires might invest in such crazy projects)
In general: an unhealthy lifestyle. In the relevant context the overwhelming majority of people die of diseases when relatively old (and not accidents or violence).
Other than that: suicide is often underrated - it is often the main non-disease cause of death for males.
(Eg when checking the stats for my own demographic I had about a 6.55% risk of death the next 30 years. Out of this some 10% were from suicide, 5% from accidents and only 1.5% from infectious diseases but over 50% from malignant neoplasms and circulatory system diseases.)

Mail him and ask?
I was assuming you meant something like "willing to go against the dominant norms in one's society" by it, which is close related to Openness.
I'd expect those people joining/starting new religions to be more open, thus the operalization of your hypothesis in terms of big5-Openness. There should probably be studies on smaller religions, such as new age, which might aptly be called new.
