Communication is a skill I have to learn, master and use. But the majority of the gains from such a skill go to the OTHER person (or people) I am communicating with. If another team member communicates nothing, I am the one lacking information. If I communicate everything, I am no better informed than when I started. It's a classic tragedy of the commons.
