It's that time of year again.
If you are reading this post and self-identify as a LWer, then you are the target population for the Less Wrong Census/Survey. Please take it. Doesn't matter if you don't post much. Doesn't matter if you're a lurker. Take the survey.
This year's census contains a "main survey" that should take about ten or fifteen minutes, as well as a bunch of "extra credit questions". You may do the extra credit questions if you want. You may skip all the extra credit questions if you want. They're pretty long and not all of them are very interesting. But it is very important that you not put off doing the survey or not do the survey at all because you're intimidated by the extra credit questions.
It also contains a chance at winning a MONETARY REWARD at the bottom. You do not need to fill in all the extra credit questions to get the MONETARY REWARD, just make an honest stab at as much of the survey as you can.
Please make things easier for my computer and by extension me by reading all the instructions and by answering any text questions in the simplest and most obvious possible way. For example, if it asks you "What language do you speak?" please answer "English" instead of "I speak English" or "It's English" or "English since I live in Canada" or "English (US)" or anything else. This will help me sort responses quickly and easily. Likewise, if a question asks for a number, please answer with a number such as "4", rather than "four".
The planned closing date for the survey is Friday, November 14. Instead of putting the survey off and then forgetting to do it, why not fill it out right now?
Okay! Enough preliminaries! Time to take the...

Thanks to everyone who suggested questions and ideas for the 2014 Less Wrong Census/Survey. I regret I was unable to take all of your suggestions into account, because of some limitations in Google Docs, concern about survey length, and contradictions/duplications among suggestions. The current survey is a mess and requires serious shortening and possibly a hard and fast rule that it will never get longer than it is right now.
By ancient tradition, if you take the survey you may comment saying you have done so here, and people will upvote you and you will get karma.
Right, let's try and explain...
Consider either an infinite universe, or better yet, a Tegmark multiverse. In this infinite universe, there will be infinitely many copies of you, and of the world. Some will be run on what we would clearly consider to be simulations (a sci-fi super computer programmed by elegant post humans or bug-eyed monsters). Some would be in places we would consider "real". Other would be in places we might or might not consider to be simulations (eg on a giant game of life board, inside a tower of simulations with no conscious simulation at any level, etc...). Add in dust theories, by which we can consider that we are sequences of events from wildly different space-time zones in the multivese.
Amazingly, we can still make decisions in this setting, by appealing to principle like entropy or artificial induction (ie "induction may or may not work, but if it doesn't work, we can't do anything anyway, so we may as well assume it works"). However, asking "are we a simulation" involves some sort of dividing an infinite number of copies of us (some clearly simulations, some occasionally simulations (see the dust theories) some completely ambiguous) by another infinity, without a clue of as to what measure to put on the whole collection. And the answer, if calculated, would be dependent entirely on the assumptions we made and would not be in any way observable.
MWI suffers partially from a similar problem (how do we count those places where we are MWI simulations on classical computers? Waveform collapse simulations on quantum computers? Universes where MWI is false?) and partially from my lack of understanding of what "quantum measure squared" is. It does not feel like classical probability, see http://lesswrong.com/lw/ixr/quantum_versus_logical_bombs/ and http://lesswrong.com/lw/g9n/false_vacuum_the_universe_playing_quantum_suicide/ . Until I sort that out, I can't even trust an empirical experiment to confirm MWI, let alone logical arguments.
Hope that helps clarify what I mean! Subquestions of these (like "will we see god-like beings saying "it's all a simulation!"?" or "will quantum mechanists come to accept MWI?") I could have answered, but not the questions as asked.
