I'm not sure how many people here are fans of science fiction, but there<br>
was a big brouhaha at this years awards (which I'll ignore), and one of<br>
the results was the proposal of a new method of choosing winners:<br>
<br>
*Short Title: E Pluribus Hugo (Out of the Many, a Hugo)*<br>
Moved, to amend section 3.8 (Tallying of Nominations), section 3.9<br>
(Notification and Acceptance), and section 3.11 (Tallying of Votes) as<br>
follows:<br>

So this is basically cumulative voting IRV? I suppose it's better than<br>
ordinary IRV, but if they're using an Approval ballot, why not just use<br>
Approval to begin with?<br>
<br>
Do they want a proportional representation method or a majoritarian one?<br>
The reference to avoiding slates seem to suggest to me that they want a<br>
proportional representation method, or at least something that is closer<br>
to a PR method.<br>
<br>
As a positional elimination method, it could suffer path dependence.<br>
Consider someone nominating (voting for) X, Y, and Z. Say now that Y is<br>
very narrowly eliminated at some point, but if the person had voted for<br>
X and Y alone, he would have given enough of his vote to Y to have kept<br>
Y from being eliminated. So the claim that "[i]n other words, you can<br>
safely nominate anything you feel is Hugo-worthy" doesn't seem to be<br>
strictly true. You can safely nominate anything that is relatively<br>
unpopular, but if it gets popular enough, it may draw enough support<br>
away from the others you would also like to nominate.<br>
<br>
If I were to construct a majoritarian ballot system with Approval<br>
ballots, I would just use Approval. There's a similar "drawing away from<br>
other popular candidates" problem (the chicken/Burr thing), but Approval<br>
is much simpler and doesn't repeated iteration.<br>
<br>
For PR, the question is much harder. With computers, you could use PAV,<br>
sequential PAV or birational voting. However, the non-sequential ones<br>
require a lot of recounts and are probably not feasible for manual<br>
elections. Sequential ones are simpler but the proportionality might not<br>
be obvious.<br>
