I think one component of all of this that sometimes gets ignored is courage. In all of human history, you had to have the guts to "say it to my face" so #1. you had to think what you had to say was really worth saying and #2. you had to think it through a little so people didn't think you were a complete idiot...That courage requirement used to be a major filter between thoughts and words. Now that filter is gone. I think they touched on that a little in the studies you reference. Good article! Thanks.
