Thank you for taking the time to have a look at the questionaire and
for your comments.

I did not meant "force" when I wrote "make" but rather meant: "to make
it probable that voters vote honestly". I will change the wording to that
now that I know the original wording was misunderstandable.

Please do not begin with polemics again. Certainly anti-strategic properties
are not nonsense but just something one can find important or not. The purpose
of the question was exactly to find out how important we find it that the
method is not very vulnerable to strategic manipulation.

But that's what was meant by "anti-strategic properties": properties which
increase the probability that people don't vote strategically.

The reason why I don't like such options is this: When I give the voter an
option whose purpose it is to let the voter change his vote dependent on the
other votes cast, then I explicitly introduce a strategic device and thereby
increase but not decrease the probability that voters will think and behave
strategically instead of sincerely.

Sorry, that first sentence was too complicated for me. Could you put that again

What I meant was this: When a voter expressed that s/he prefers A to B, we
interpret this to mean that if s/he could choose between A and B, she would
choose A. Now what do we think the voter would choose when s/he put A and B
at equal ranks? Do we assume that s/he would delegate the decision by, say,
asking a friend to decide, or do we assume that she would throw a coin?
