Not to be crass, but given the assumption that Wei_Dai is not saying something utterly asinine, does your interpretation of the hypothetical actually follow?

Hang on! My last comment was a reply to your question about when it could be rational to select the third box. I have already said that the original example was unclear. It certainly didn't suggest an infinite sequence - and I wasn't trying to suggest that.

The example specified that choosing the third box was the correct answer - under the author's own proposed decision theory. Surely interpretations of what it was supposed to mean should bear that in mind.

I don't believe we're actually arguing about anything worth caring about. My understanding was that Wei_Dai was illustrating a problem with UDT1 - in which case a single scenario in which UDT1 gives an unambiguously wrong answer suffices. To disprove Wei_Dai's assertion requires demonstrating that no scenario of the kind proposed makes UDT1 give the wrong answer, not showing that not every scenario of the kind proposed makes UDT1 give the wrong answer.

Are you sure you are taking the fact that he is UDT's inventor and biggest fan into account? He certainly didn't claim that he was illustrating a problem with UDT.

...you're right, I'm misreading. I'll shut up now.
