The glue that keeps the illusion that communication is happening alive is that pernicious little head nod. No one wants to be the person that stops the speaker every 30 seconds to get clarification on every piece of jargon and ill-explained thing that comes out of their mouths. So the slight misunderstandings snowball until you're really getting a fraction of whatever the speaker is trying to communicate.
At this point, unless the head nod is aggressively positive, I have come to assume it actually means they have stopped following fully. I then have the decision as the speaker whether to ask for questions or just slow down a bit or stop altogether and see if they naturally show their curiosity.

The beautiful irony is that I simultaneously understand what the author means by this and I find it completely incomprehensible. Well, it's not that bad, but I guess it's just that the concept has morphed into such a complex shape of neurons in my head that doesn't seem to quite fit the words this author is saying, so it doesn't jive quite right. I think I know what they mean, but maybe I don't.
