This book is an outcome of the Socionics Research Framework.1 The roots of Socionics lie in the 1980s when computer scientists in search of new methods and techniques of distributed and coordinated problem-solving first began to take an engineering interest in sociological concepts and theories. Just as biological phenomena are conceived of as a source of inspiration for new technologies in the new research field of bionics, computer scientists working in Distributed Artificial Intelligence (DAI) became interested in exploiting phenomena from the social world in order to construct Multiagent Systems (MAS) and, generally, to build open agent societies or complex artificial social systems.
