It depends on your definition of supernatural, and most people on LessWrong seem to have a very narrow definition of supernatural. I think Eliezer once wrote a post about it, but I don't believe he cited any references. Some definitions of supernatural would require many people on here to revise their estimate significantly upward. I took the lack of a definition to mean we should use any and all possible definitions of supernatural when considering the question, which is why I picked 100 percent. There's actually been a discussion on whether simulations imply God, and most answered no. I thought the reasoning some used for that was rather peculiar. That discussion of course didn't include any citations either.
