Communication between and among people is very complex. There are many channels and nuances. However, for the purpose of innovation, I have found the following simple model useful. It is based on knowledge and values.
If people seeking to communicate have the same knowledge and the same values, communication is very easy. This is what happens between friends. It's comfortable. However, if you really have exactly the same knowledge and values, the transactions carry no real meaning. Nothing new can be created.
If the people have the same knowledge but different values, when communication is attempted, an argument usually results. Operating on the same knowledge with different values results in different interpretation and prioritization of the knowledge. This quite often happens in politics and religion. (And, it may be going on in America right now.)
If people have different knowledge and values, not much communication can take place. If an attempt at communication is made, a lack of understanding results, or at best a misunderstanding occurs.
If people have different knowledge but the same values, a conversation can result. In a conversation, innovation can occur.
