The psychoanalyst uses the scientific method in the analytic situation more often than he is consciously aware of. Initially psychoanalysis used a great number of analogies derived from the then current physical model, the Newtonian. Nowadays the analogies are based on cybernetics. From the standpoint of games theory the analytic situation is a two-person game in which the central theme is one of the participants. As the analyst listens with free-floating attention, the free associations appear to have a recurrent pattern that is repeated as obsessively as the theme in Ravel's Bolero. The analyst, functioning as a 'computer', records and groups, and builds hypotheses. The method is always logical even when the object of observation is not. The hypotheses can be verified by any observer willing to play the game adhering to the rules. The communications received and grouped in the manner described are used to make predictions with a high degree of validity.
