Eh, it depends.
One example is projects I had to do with other students at school. If you put me with my friends, I'd generally shove it and did what I was told, because I knew that while I had some nice ideas of my own, they wouldn't understand them anyway.I simply didn't want to bother with going through the whole process of having a discussion about it. If you put me with the lazy folks in the class, I'd generally be on their balls the entire time telling them to do some work, while coming up with my own ideas and steering my groupmates as well.
In an optimal setup I'm in a group with people of similar intellect and interests as me, and in those groups I always end up being a proper leader/teacher. Assessing the situation, knowing the big lines of all divisions/sections and through that looking at the shortcomings we have and inspiring my teammates to do something about it.
I need to keep the overview, it's just me. I don't need to know all details of what everybody is doing (as generally the people in question are better at their own job than me), but I need to know enough to figure out where we are failing so I can teach, connect, improve and inspire the weaker links.
