text: Another reason is that hearing others opinion on the matter can bring your decision to be the right decision, like if your thinking of stealing a candy bar and you ask your friend if you should do it or not, usually you would do something that you friend says, stealing isnt the best option, so you leave the store without doing anything wrong, you could've stolen it but your friend didn't want that so you agree with them. Usually peoples opinion on something is biased so asking someone else is really good for changing your answer for the better. And if your buying food for someone that has an allergy and you ask your friend for advice for which one you should get and they mention that one of the things you were going to buy has something that is allergic to that friend ,you basically almost killed someone, and asking for someones advice helped you out. When making a choice you always want to pick the best choice and having more than one person making that choice can help a lot.
