The Open Thread posted at the beginning of the month has gotten really, really big, so I've gone ahead and made another one. Post your new discussions here!
This thread is for the discussion of Less Wrong topics that have not appeared in recent posts. If a discussion gets unwieldy, celebrate by turning it into a top-level post.
I believe even personal identity falls under this category. A lot of moral intuitions work with the-me-in-the-future object, as marked in the map. To follow these intuitions, it is very important for us to have a good idea of where the-me-in-the-future is, to have a good map of this thing. When you get to weird thought experiments with copying, this epistemic step breaks down, because if there are multiple future-copies, the-me-in-the-future is a pattern that is absent. As a result, moral intuitions, that indirectly work through this mark on the map, get confused and start giving the wrong answers as well. This can be readily observed for example from preferential inconsistency in time expected in such thought experiments (you precommit to teleporting-with-delay, but then your copy that is to be destroyed starts complaining).
Personal identity is (in general) a wrong epistemic question asked by our moral intuition. Only if preference is expressed in terms of the territory (or rather in a form flexible enough to follow all possible developments), including the parts currently represented in moral intuition in terms of the-me-in-the-future object in the territory, will the confusion with expectations and anthropic thought experiments go away.
