Episode notes
Mock Election Exercise
- Dan Ullman, a math professor, uses a mock election in his class.
- Students experiment with different voting rules and see how outcomes change.
Impact of Voting Systems
- Changing election rules can change winners, especially in elections with many candidates or high polarization.
- A study by Romain Lechat simulated various voting systems and found different outcomes in one-third of the cases.
Plurality Voting
- Plurality voting, or "first past the post," is simple but has flaws.
- It can lead to winners without a majority and is vulnerable to vote splitting and the spoiler effect.
