* '''Social Choice Theory''' — The analysis of collective decision-making and how individual views become a single group choice.
* '''Arrow's Impossibility Theorem''' — The mathematical proof that no voting system can satisfy a specific set of "Fairness" criteria simultaneously.
* '''Condorcet Paradox''' — A situation where a group prefers A over B, B over C, and C over A (a "Cycle" with no winner).
* '''Ranked Choice Voting (RCV)''' — A system where voters list candidates in order of preference (1st, 2nd, 3rd).
* '''Borda Count''' — Assigning points to ranks (e.g., 3 points for 1st place, 2 for 2nd) and summing them up.
* '''Gibbard-Satterthwaite Theorem''' — The proof that almost every voting system can be "Gamed" by strategic voting (lying about your preference).
* '''Independence of Irrelevant Alternatives (IIA)''' — The idea that the choice between A and B shouldn't change just because a third candidate (C) enters the race.
* '''Dictatorship Criterion''' — The requirement that the group's decision shouldn't just be whatever one single person wants.
