text: My last reason would be that some people may just want reassurance that they are doing the right thing from multiple people/sources. They could already know what they're doing, but they could still want other people's opinions and insight. For example, if I was fighting with a friend, and I was trying to resolve it and already knew what I was going to say, I could ask multiple people if I should should say that or not, or how they think things would turn out. So, if a person asked their friends what they should do and they all thought it wouldn't have a good outcome, they could take their friend's advice and change what they were doing.
