This only works when different sources share similar feature distributions and semantic relationships. The M or B game breaks down when you play with someone who knows obscure people you've never heard of. Either you can't recognize their references, or your sense of "semantic distance" differs from theirs. The solution is to match knowledge levels: experts play with experts, generalists with generalists. The same applies to decoding ancient texts, if ancient civilizations focused on completely different concepts than we do today, our modern semantic models won't help us understand their writing.
