ELI5: Explain Like I'm 5

Generalized expected utility

All right kiddo, let's talk about something called generalized expected utility. This is all about how people make choices and decisions.

So, let's say you have some money and you want to spend it on something fun like toys, candy or games. But you also want to make sure that you don't run out of money and have enough left for other things you need. How do you decide what to buy?

That's where generalized expected utility comes in. This is a way to figure out what choice will give you the most satisfaction (or happiness) based on how likely different outcomes are.

For example, let's say you have $5 and you are trying to decide between buying a toy or some candy. If you buy the toy, you know for sure you will have the toy, but you might not like it as much as you thought you would. On the other hand, if you buy the candy, you know you will enjoy eating it, but you might run out quickly.

Generalized expected utility helps you weigh the different outcomes based on how likely they are to happen. So, if you think there's a very high chance you'll really enjoy the toy, and a lower chance you'll get bored with it quickly, then buying the toy might be the best choice. But if you think there's a lower chance you'll really love the toy, and a higher chance you'll want more candy later, then buying the candy might make more sense.

This same idea can be applied to bigger decisions too, like buying a car, choosing a career, or deciding on a medical treatment. It's all about weighing the different possible outcomes and figuring out which choice will give you the most satisfaction in the end.

So, that's a basic explanation of generalized expected utility, kiddo. It's a fancy way of saying that we make choices based on the likelihood of different outcomes and how much satisfaction they will bring us in the end.
