I make no comments on the lottery example, because I would need to understand it better, and I have too little time now. But I may suprprise you with a parallel from pre-QM philosophical work on the interpretation of probability. Cournot's Principle claims that probabilities have no interpretation, no relevance to our lives, unless they are close enough to 0 or 1, "enough" depending on the practical purpose. Before one screams "this is crazy", he had better look at the appeal of this idea among the most prominent students of these matters in the 20th century. However, what little work has been done on a decision theory conforming to this principle is patently inadequate, IMO, and this, I think, is the reason for its current obscurity. The decision theory I have started for MWI will work for Cournot's Principle, too. If one cares for references, search for "Glenn Shafer" and "Cournot's Principle", especially the papers titled - Why did Cournot’s principle disappear? - That's what all the old guys said - A Betting Interpretation for Probabilities and Dempster-Shafer Degrees of Belief [...] I spelled out the sequences that Everett implies in my earlier > response.

I have already expressed disagreement, as a technical matter. I am not certain where the misunderstanding lies, but I suspect it is in presuming equal probabilities derived from sheer ignorance, as at least one other contributor claims. If you really insist on this opinion, it should be discussed in a separate conversation -- appealing to your "logical and mathematical skills", as you say.
