text: As an example, you go to the store to buy your favorite product, but someone tells you it is cheaper at another store. You can make the best choice by asking someone else what they think, this saves time when you find out that it is not cheaper. When listening to someone else's advice make sure you listen for bias. If that person who told you it was cheaper here than at the other store, then they might have been bias against the other store. They would lie to you so you would avoid the other store.
