Doesn’t the inverse gambler’s fallacy cut against the multiverse? Many universes elsewhere no more explain why this one is fine-tuned than many dice rolls elsewhere explain why this roll came up double six.

This is Ian Hacking’s argument, and it is a real one in the literature. The standard reply is that observer selection makes the difference: we could only find ourselves in a life-permitting universe, which blocks the fallacy charge in the multiverse case in a way it does not in the dice case. Whether that reply works is an ongoing debate (Roger White against Darren Bradley, for instance). It is a point in the theist’s favor that is often left out, and it belongs in any serious weighing of the multiverse.
