In the field of Risk, the process of risk communication is important for decision making because there various people standing different thought and knowledge.
Risk communication is the change from a non-cooperative game to a cooperative game by the words of game theory .
Some books say that "We fail the communication if we start communication with persuasion." and "There is not the way to success the communication surely."
"Trust" is an important key-word.
Some people intend to change the thought of audiences by psychological techniques. (I do not like this method.)
Risk is defined in risk evaluation . But as I explained in risk cognition , the sense of citizen is differing to specialists. Risk communication is not a method to explain the "right" to citizen.
