text: One reason another opinion may be helpful is that person may have more experience than you. One example of this is that you might be thinking about getting a pet, but you're not sure if you can take care of it properly. You could talk to a friend that already has a dog to see how much work it is... and then proceed to get a fish. Another example of this is if you want to by a video game that doesn't have great reviews, but are like me and don't use that to judge how good a game is. You can ask someone if the reviews are an honest reflection of the game. Then you can not buy it because it was too expensive anyway. My final example is if you don't know if a DC movie is any good because their last couple have been... interesting. You can ask a friend who already went to the movie if it's any good. Then you can hear a 15 minuet rant about how it's "A work of art" and "How stupid of a question is that." Hmm, maybe I should rethink how useful my friends "experience" is.
