The "zero-info" refers only to knowledge of other voters' preferences. 
We presumably know how many candidates are in the race, and our own
degrees of preference for each candidate, so "zero-info" is sort of a
misnomer in that sense.

Of course, in real-life the opposite could easily be true, particularly
in small local elections which don't receive much press coverage.  You
may never have heard of the candidates, but can guess at the amount of
support they are receiving by observing the amount of campaign junk-mail
received, number yard signs seen, etc.
