Meta comment: If this questions were in separate comments, I'd upvote/downvote differently. I'm interested in thoughts/arguments related to probability of simulation and I have little interest in solipsism or lucid dreaming. They don't seem very much related topics to me. Am I missing something?
They all seem to be asking variants on the question "how likely is apparent reality real?". They also all seem to have weird properties as far as evidence is concerned, because the observable evidence must all come from the very source (observed reality) whose credibility we're questioning.
Also, except for the solipsism one, they seem to be questions where, contrary to LW canon, it might be a good idea to deliberately self-delude (by which I mean, for instance, not bothering to look at the evidence in-depth). If I really felt a .5 probability in ...
Often, there are questions you want to know the answers to. You want other people's opinions, because knowing the answer isn't worth the time you'd have to spend to find it, or you're unsure whether your answer is right.
LW seems like a good place to ask these questions because the people here are pretty rational. So, in this thread: You post a top-level comment with some question. Other people reply to your comment with their answers. You upvote answers that you agree with and questions whose answers you'd like to know.
A few (mostly obvious) guidelines:
For questions:
For answers:
This thread is primarily for getting the hivemind's opinions on things, not for debating probabilities of propositions. Debating is also okay, though, especially since it will help question-posters to make up their minds.
Don't be too squeamish about breaking the question-answer format.
