this is only with 11 votes, but interesting. i did the same sets of
3-5 candidates, but with score voting and irv. (only it gives you the
results for all methods no matter which method was actually used. but
you can look at the description for each "election" to see which data
set is actually being referred to.)
point is, we now should look at the cases where the irv and range
voting winner differed, and then see how well those differences do in
a head-to-head matchup.
* first election: al gore, bill clinton, barack obama
obama won with score voting _and_ irv, but there's still something
interesting here. if you look at the extrapolations from the score
voting election (e.g. converting it to ordinal data to see who would
have won with instant runoff) obama basically owns it - though he ties
with gore under the approval extrapolation. but if you look at the
data from the irv election, gore wins the extrapolations for score
voting, approval voting, and i.r.n.r. (Instant Runoff Normalized Ratings).
* last election: 7 candidates, including john stewart and ron paul
ron paul won the i.r.v. (tied with pelosi), and john stewart won the
i think the data set is simply too small here to do anything very
useful, but this would be an interesting idea to follow up on. it
might be useful to do a meta-analysis of previous score voting and
ranked voting polls.
