Analyze a sequential election agenda when all candidates have equal first- and second-place counts. Use a concrete cyclic preference profile to show how the final-round position can determine the winner.
Test Fairness of an Election Agenda under Equal Ranking Counts
Company: SIG (Susquehanna)
Role: Data Scientist
Category: Statistics & Math
Difficulty: medium
Interview Round: Technical Screen
Voters rank candidates A,B,C. Each candidate receives the same number of first-place rankings and the same number of second-place rankings. Candidate A proposes that B and C first compete head to head, then the winner competes against A. Is this procedure necessarily fair or neutral among the candidates?
### Constraints and Clarifications
Use pairwise majority voting from strict complete preferences. Clarify how ties are handled; construct a no-tie example so the conclusion does not depend on an unstated tie-break. Here fairness means that equal positional support does not justify granting one named candidate a privileged agenda position, rather than a claim about every possible voting axiom.
### What a Strong Answer Covers
Build a profile satisfying the positional constraints, compute both head-to-head rounds, and distinguish positional counts from pairwise preferences and agenda effects.
### Follow-up Questions
- What happens if B rather than A receives the final-round position in the same profile?
- Do equal first- and second-place counts imply all pairwise contests are tied?
