Classifications are now so complicated that it is not possible for behavioral scientists to communicate with one another about the nature of problems. A room full of social scientists has as many definitions of "schizophrenia" or "psychopath" or "character disorder" as the number of persons in the room. No review of the psychological literature will clarify what the names for problems really mean; one current revision of a standard psychiatric dictionary proudly states that the volume contains over 4000 new terms not included in the prior edition. This number is not a testimonial to the progress made in studying people's problems; rather, it is an admission of the confusion and chaos that pervade the field of "problemology."
