Episode notes
Political Polarization Paradox
- Political polarization is increasing, with more independents than Democrats or Republicans.
- However, these independents often vote reliably with one of the major parties, creating instability.
One-Dimensional Politics
- One-dimensional political dynamics, like everyone moving in the same direction, can lead to instability and extreme outcomes.
- This can result in the election of extreme leaders and the potential collapse of democracy.
Third-Party Spoiler Effect
- Forming a third party in a polarized environment can backfire, creating a spoiler effect.
- This effect divides the vote and benefits the party furthest from the third party's views.
