If there is a 99 % chance of a good world and a one% chance of a bad world, aren't there just two worlds, 50 per cent of which are bad? You say the worlds don't count equally, but why not, and in what sense? Ah, itis a perfectly good question. As you say, versions of it have been asked many times. I predict that i can articulate it very well, and it will not stop people from asking the questions. This is an issue that arises in the many world's interpretation that just doesn't arise in other theories. And therefore, you know, it's ok to struggle with understanding what is going on here.
