Two examples of small vote failures--
1. Approval- 3 Voters
A B
1st Choice 2 1
2nd Choice 0 2
Total 2 3
B wins using approval 3-2. A wins head to head 2-1.
2. Instant Run-Off- 5 Voters
A 2
B 2
C 1
C v. A: 3-2
C v. B: 3-2
C loses in IRO, C wins in head to head.
3. Any more ideas for small (smallest) vote examples for other defective
methods?
