Preference Voting

This plugin lets you rank multiple options in order of preference, instead of just choosing one.

This way, the most preferred option by all the voters can win, even if it is not the most popular one.

This voting method is also known as Condorcet method for Voting, Card Sorting, Ranked Choice Voting (RCV) or Instant Runoff Voting (IRV).

Examples:

Setup:

• Available options A, B, C, D
• People voting 5

Traditional voting:

Votes:

• User1 = A
• User2 = A
• User3 = B
• User4 = C
• User5 = D

Results in traditional voting:

• A = 2
• B = 1
• C = 1
• D = 1

Explanation:

A gets 2 votes from user1 and user2 and all the other options get one vote each. Users 3, 4 and 5 might prefer to have the option B before having the option A, but since the majority voted for A, A will be the winner.

Voting with the plugin:

Votes:

• User1:
  • A
  • B
  • C
  • D
• User2:
  • A
  • B
  • D
  • C

  • A
• User4:

  • D
  • A
• User5:
  • D
  • B
  • C
  • A

Results voting with the plugin:

• B
• D
• C
• A

Explanation:

If we calculate the average position of the options in the votes the winner would be B.
