How Does Utility and Risk Preferences Part 1 - Utility Function Work?

Imagine you're choosing between two ice cream flavors, one is your favorite, but it’s a bit messy to eat; the other is new and exciting, but you’ve never tried it before.

Utility is like how happy or satisfied you feel after making that choice. A utility function helps us measure this happiness in numbers so we can compare different choices easily.

A utility function is like a special calculator that turns things you care about, like ice cream, toys, or even money, into numbers that show how much you like them. For example:

• If your favorite ice cream gives you 10 happiness points,
• And the new one gives you 8 happiness points,
• You’ll probably choose the first one.

But if the new ice cream has a chance of being super amazing (like having sprinkles that glow in the dark!), it might give you more than 10 points, and suddenly, you're excited to try it!

Utility functions help us understand how people make choices. They’re like invisible scores that guide our decisions, whether we’re picking ice cream or choosing between playing video games or reading a book.
