+I realize this must seem impossibly rude and presumptuous of me. Yudkowsky _said_ he doesn't know what it feels like from the inside! That's a report out his own mental state, which he has privileged introspective access to, and I don't! What grounds could I possibly, _possibly_ have to think he's not telling the truth about his own mind?

+It's a good question. And my answer is, even without mind-reading technology, people's minds are still part of the same cause-and-effect physical universe that I can (must) make probabilistic inferences about, and verbal self-reports aren't my _only_ source of evidence about someone's mind. In particular, if someone's verbal self-report mis-predicts what we know about their _behavior_, it's far from clear that we should trust the report more than our senses.
