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 agree that it's ugly to think of the weights as a pretense on how real certain parts of reality are. That's why I think it may be better to think of them as representing how much you care about various parts of reality. (For the benefit of other readers, I talked about this in What Are Probabilities, Anyway?.)
Actually, I haven't completely given up the idea that there is some objective notion of how real, or how important, various parts of reality are. It's hard to escape the intuition that some parts of math are just easier to reach or find than others, in a way that is not dependent how human minds work.
