A popular current view is that 'lack of communication' explains the ills of the world. The author feels that, in fact, lies, distortions, selective reporting, and ambiguous statements are necessary in interactions where differences are advantageously concealed. For example, such statements are designed to transmit requests or demands in personal situations of conflict; to allow 'consensus by misunderstanding' and thus permit political action; and to protect individuals and groups from those who may have power over them. Lack of communication is a consequence of conflict and differences.
