Research sub-group on communication techniques

Communication techniques are concerned with problems of the realization and questions of practicability and efficiency of the communication. However, there is a strong tendency towards the opinion that intelligibility is the central problem since perfectly transmitted structures may be differently or even not at all understood by the receiver; this is not the case if the transmitted news is not in the intersection of the 'repertoires', which comprises the vocabulary, knowledge and experience sender and receiver have in common. Communication techniques in this aspect of communication theory are to process the news, so that it may be effectively transmitted and understood on the basis of the intersection of the repertoires. Examples of communication techniques are given (term risk, and the meaning of small probabilities)
