About ollpoll.org

Ollpoll.org allows voters to participate in polls using the OllPoll Voting Method.

Ollpoll Voting Method

OllPoll combines rated (range voting) and ranked (preference) voting methods, while still remaining simple. Here is how it works

• voters rate all candidates on a 5-point Likert scale
• Likert scale is internally mapped to a 0-to-4 scale
• candidates are first sorted by their total scores
• then the order is preference-corrected from bottom up

Preference correction swaps the position of adjacent candidates when the lower scoring candidate is more preferred then the higher scoring one.

Properties

OllPoll always picks the Condorcet winner, if there is one. Condorcet cycles are impossible, because preferences are checked only between neighbouring candidates.

A winner is always selected, ties are not possible. If there are equally preferred candidates, then the one with higher score wins. If there are equally scoring candidates, then the one listed higher on the initial ballot wins.
