Human communication can be about many things, but it should be about something, something which the receiver understands and can act upon, and it should be information which the sender intended the receiver to receive and to act upon. The point of communication is to change the receiver’s behavior, and that receiver might be himself at a future time. Just sending out information into the void or receiving random noise instead of data is a useless exercise in wasted energy unless something gets done, and preferably a thing gets done which was intended, or the information conveyed was counterproductive. My point is that communication is intended to change something. Even wrong behavior is better than nothing, because it means the channels of communication functioned, and that means that adaptations can be made so the future communications can be made more effectively. When there is accurate feedback then progress can be made.

Ignore incoming data which cannot change some future behavior.
