ELI5: Explain Like I'm 5

Duverger's law

Hey there kiddo! Have you ever heard of Duverger's Law? No? Don't worry, I'll explain it to you.

Duverger's Law is a rule that tells us something about how people vote in elections. Have you ever played a game with your friends where you vote on what game you want to play? If you have, then you know that the game with the most votes wins, right?

Well, it's kind of the same with elections. When people go to vote, they might have different ideas about who they want to vote for. Some might want to vote for a person or a party that is similar to them or their beliefs, while others might want to vote for someone different.

Now, let's say that there are 3 candidates running for office: Candidate A, Candidate B, and Candidate C. If everyone voted for the candidate they liked the most, there might not be a clear winner. But, if people realized that Candidate A and B are similar, they might decide to vote for one of them instead of Candidate C, who is different.

This is where Duverger's Law comes in. It tells us that in countries where there is a system of voting called "first-past-the-post," the number of political parties tends to be two. This means that either Candidate A or Candidate B would win, and not Candidate C, because people would be more likely to vote for the candidate who is similar to them.

So, Duverger's Law is a rule that tells us that when people vote, they tend to choose candidates who are similar to them, which often leads to just two political parties in countries with "first-past-the-post" voting, which means that only one candidate can win.

I hope that helps you understand Duverger's Law a bit better, kiddo!
