ELI5: Explain Like I'm 5

Principle of Parsimony

Okay kiddo, you know how sometimes things can get really complicated and confusing? Well, the principle of parsimony is a rule that helps us make sense of things in the simplest way possible.

Just like how it's easier to clean up your toys when you put them back where they belong instead of making a big mess, the principle of parsimony tells us that the simplest explanation is usually the best one.

So, when scientists are trying to explain something, they don't want to come up with a really complicated answer that's hard to understand. Instead, they want to find the simplest explanation that still makes sense and fits with all the information they have.

This helps scientists make good predictions and solve problems more easily. It also saves time and makes things less confusing for everyone.

So, remember, when trying to understand something, always look for the simplest explanation that makes sense. That's the principle of parsimony!
