Each voter ranks the available choices in order of preference. Choices are compared head-to-head against every other choice based on voter rankings. For each head-to-head comparison, the choice preferred by more voters receives one point; ties result in half a point each. The choice with the highest total points from all comparisons wins.
Some options might appear with few or no points if they lose most pairwise comparisons.
Pros: Clearly identifies broadly acceptable choices, easy to interpret results, and reduces strategic voting. Cons: Can be complex due to multiple pairwise comparisons; less intuitive if there are many options.
