During the last days the discussion on
this list has focused primarily on the terminology. Coincidently I am working on
a paper that tries to define "preferential voting".
Literature offers numerous understandings and
definitions:
- 'preferential voting' is often used as a synonim
for Alternative Vote or IRV
- 'preferential voting' is sometimes used as
another name for STV
- 'preferential voting' is often used to
denote 'ranking methods' (thus including STV, AV, Borda, etc.)
- 'preferential voting is often used to denote a
preference for a single candidate within List PR (this definition is used mainly
in Europe)
- mathematicians put first-past-the-post in the
group of preferential voting schemes, but approval voting is not a member of
this group
- some authors put US primaries under 'preferential
voting' (Katz, for instance)
Is it possible to define preferential voting at
all?
I'd be grateful for any comments.
