I have trouble with (2). We could assume that "how the voter would vote"
means optimal, above-mean approval strategy. But obviously that is a
problem for a definition of "sincerity." It would also make approval
satisfy NZIS.</pre>

I don't have a big problem with plain Approval satisfying NZIS. Of
course Approval is promoted as a<br>
method that invites voters to strategize.<br>
<br>
<blockquote type="cite">
<pre wrap="">Otherwise we could choose to not define "how the voter would vote." But
in that case nothing prevents a strategically unwise vote from being
sincere, so that I don't see how DMC could satisfy NZIS. </pre>
</blockquote>
If , by some absolute standard in the voter's mind, the voter sincerely
"approves" at least one but not all of the candidates<br>
then "sincere approval" is clearcut. I suppose if this isn't the case
then as you say if we leave undefined "how the voter<br>
would vote" there is still 0-info. approval strategy (so plain
Approval doesn't really meet NZIS).<br>
<br>
<blockquote type="cite">
<pre wrap="">You would have
to claim that DMC has no zero-info approval strategy.</pre>
</blockquote>
It seems clear that DMC has no zero-info. *ranking* strategy. (Is that
what you meant?) But unless we define "sincere approval"<br>
as "optimal zero-information approval ('strategy')", then DMC
perhaps doesn't fully meet NZIS.<br>
