Why You Only Ever Get Two Choices | Duverger’s Law Explained

Описание: Why do some democracies keep ending up with just two big parties, while others have a dozen? It's not culture or luck. It's the voting rules. Here's Duverger's Law explained in 90 seconds.

In the 1950s, French political scientist Maurice Duverger noticed that "first-past-the-post" elections (one winner per district, most votes wins) tend to produce two-party systems. This video breaks down the two forces behind it, the mechanical effect and the psychological effect, and shows why proportional representation leads to multiparty coalitions instead. We also look at why it's a tendency, not an iron law, using the UK's 2024 election.
