The Asymmetry (population ethics)

Hello there! Are you ready to learn about asymmetry in population ethics? Great, let's start!

Okay, first, let me explain what population ethics is. It's all about figuring out what we should do when it comes to making decisions that affect large groups of people. For example, if we have resources to share, who should get them and how should we decide?

Now, asymmetry means that two things are not the same. In population ethics, we talk about the asymmetry between good and bad things that can happen to people.

Let me explain this better. Imagine you have a cookie. If you eat the cookie, it's good for you, right? But if you don't eat the cookie, it's not really that bad. You might be a bit hungry, but it's not a big deal.

However, if you were in extreme pain or suffering, that's very bad. And if you didn't get help or treatment for that pain, it would be a really big deal.

So, you see, good things like eating cookies don't have the same importance as bad things like pain and suffering.

Now, in population ethics, we have this idea called the Repugnant Conclusion. It's a bit of a complicated name, but what it means is that there's a problem when we try to compare different populations.

For example, let's say we have two populations. Population A has 10,000 people who are living good lives, not perfect, but pretty good. Population B has 10 million people who are living okay lives, not great, but not terrible either. They're just okay.

If we were to ask which population is better, it might seem like B is better because there are more people, right? But if we use the idea of asymmetry, we have to consider if the people in population B are really living better lives than those in population A.

What if many of them are suffering from extreme poverty or illness? What if they don't have access to basic needs like clean water or education?

Then we might realize that, even though there are more people in population B, it's not actually better. And that's the Repugnant Conclusion: sometimes, adding more people to a population doesn't make it better, especially if those people aren't living good lives.

So, to sum up, asymmetry in population ethics is all about recognizing that good things and bad things are not the same, and that we need to consider the wellbeing of all individuals in a population, not just the total number of people.
