Good communication is not only the precise transmission of facts and data. It is also, and basically above all, conveying the right emotions or at least not triggering the bad ones. We are social and emotional beings, so what we feel determines how we behave and what decisions we make.
The manner of delivery is of great importance. It matters whether we speak quickly, whether we constantly shoot new ideas, whether we are focused on the goal, whether we inspire, whether we are suspicious, open-minded, or maybe we use a joke as a tool to ease tension. It all counts.
Mutual adjustment of communication styles eliminates some of the problems in this area.
