About ollpoll.org

Ollpoll.org allows users to vote in polls using the Score-Then-Prefer voting method. This method combines both rated (range voting) and ranked (preference) voting methods.

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

Preference correction swaps the position of neighbouring candidates if a lower scoring candidate is more preferred then a higher scoring one.

Score-Then-Prefer 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. For equally preferred candidates the one with higher score wins. For equally scoring candidates the one listed higher on the initial ballot wins.
