text: Knowing what they know ahead of time could help you to make a better decision before something happens. For example, say two people have already gone to the college that you want to go to. One of them got accepted into the college, while the other did not. You go to both of them for opinions. The one that didn't make it into the college, tells you that they didn't keep up with there work, and stay organized which is a big reason why they didn't get accepted. So you would most likely do what they didn't do because they weren't accepted. Next you go to the one that was accepted. They tell you to work hard, never give up, and keep studying. You listen to them too, and you do all of those things. Now you have a greater chance of getting accepted into the college, because you listened to more than one person, that had different views on the situation.
