Not just juniors. Seniors too! They (we!) are not immune to stomping 5 miles down the wrong path without realising and only seeing the light after talking it through with a peer.
Yes, but with seniors sometimes you can say that something is not right or dead end and some people get angry because they think they are more skilled/experienced/knowledgeable than you.
Hearing what other people have to say and thinking about your actions in different light is skill on its own.
