Simply since many if not most experts seem to feel that they are good
if not best (for typical political single-winner elections).
This mail stream is about joining forces in defending all the good
methods. I have no problem in forming also a joint team for
supporting both rating and ranking based methods. But in this case
I'd like to make it clear for what purpose and environment each
method is good for.
In order to reach consensus on what Range is good for one could also
approach it from two different angles. We could define it as two
Range(ratings) is a method where (most) voters are expected to give
their sincere rankings. This wonderful method is at its best in non-
Range(ratings) could in theory also work in utopias where the current
political arenas are replaced with some new softer ones. In real life
some areas in life might also lose their competitive nature e.g. as a
result of people becoming richer (no need to fight on some basic
cheap stuff any more, just interest in picking the best candidate
left), but these cases may be quite marginal.
Range(approval) is a method where voters are expected to vote as in
Approval. Additionally voters are allowed to cast weak votes. This
wonderful method works quite well also in competitive environments.
In (competitive) Range(approval) I would not recommend voters to cast
weak votes unless they know what they are doing. It is not good if
voters with less strong feelings cast weaker votes than voters that
feel that they are always right and want to drive their opinions
strongly. It is not good if "altruistic and cooperative" voters have
less weight than the selfish ones. As a general rule I'd recommend
all voters to use votes of same strength (one man one vote is a good
basic rule in competitive democratic decision making).
Making a clear difference between Range(ratings) and Range(approval)
is important when discussing the benefits of each. Too often I have
seen approaches where people pick e.g. only the best parts of both
approaches (and forget the non-working cases) and assume that they
all are valid simultaneously.
