This is so because we are dealing with hypothe occurence of aecidents may be calculated in any exact sense in advance. The structure of risk is discussed using the example of genetic engineering. The shape in which the reflection on impact itself becomes part of the decision is called risk. Through risky decisions, lack of knowledge is the basis for societal communication. Risk itself is a form of communication which is rich in preconditions.
Risk is a challenge to calculate in the present an unknown future.
Decisions under risk are paradox to the extent that they attempt to include the unknown in considerations. Decisions are to be made on matters, which, in principle, cannot be decided. We always speak of communication of risks whenever this construction is used to mark out the future and missing knowledge in situation requiring decisions. Decisions with regard to uncertainty can only be made as a part of social of progress or hypothetical situations. Processing uncertainty, ambiguity and impossibility is the most distinctive characteristic of future-oriented decision making and risk communication.
