J.L. Moreno defines sociometry as the research and science of the evolution and organization of groups and the position of individuals within them. He organized and proposed Sociometry between 1915 and 1918 in refugee camps. In 1934 he quotes: “a truly therapeutic process cannot be aimed by humanity as a whole, but adequate treatment cannot be prescribed as long as humanity is not in some sense a unity and as long as its organization remains unknown”.

Sociometry is the science that studies human relationships, the trends between them and comes to fill the gap between Psychology and Sociology. The etymology and the term derive from the measurements that can be made within social networks and social groups, small and larger populations.

Sociometry is a synthesis of theory, research and practice. It is another philosophical and scientific orientation of Moreno’s complex and synthetic thinking and vision of the world. Sociometric research is a system with many tools and exercises that allows not only the social scientist Sociometrician, Psychodramatist, Sociodramatist to gain analytical perception and insight in relation to the social group or group he works with, but also the participants themselves to perceive the texture, qualities and criteria of the social groups to which they belong.

Among the social phenomena that Moreno records are the social individual, social networks, the tele, the cultural individual, the sociodynamic effect. The spectrogram, topogram, and sociometric test are some of the important tools of sociometry which should not be isolated from the whole of Moreno’s theory and applied as simple techniques.

On the contrary, sociometry is a complete system that allows, with all respect to the community and the individual, to process and resolve important dynamics in their relationships. Sociodynamics is the evolution of sociometry and captures the choices of people within the social groups they coexist and co-create, corresponding to Psychology, Psychodrama and Psychodynamics.

Moreno, in his triadic system, Sociometry – Psychodrama – Group Psychotherapy deals with the social networks of relationships of individuals within groups. He captures the complex process of human choices by making them explicit. It defines the basic laws of sociodynamics such as sociogenetic law, sociodynamic law, sociodynamic effect, sociostasis, law of social gravity and group cohesion.

It is a wonderful tool for the teacher’s classroom and for any social scientist who is called upon to coordinate and manage a group. Through sociometry it is possible to investigate the dynamics of the group and the quality of the connections between its members. “If an individual had at least once found his place in society, according to the laws that seem to control the psychological status of the population, the laws of sociogenetics, sociodynamics and social gravity, he could be safe from violations of the limits of his natural development and expansion, and denaturation into a modified form could then act as a factor. It is a form of active transformation, productive as well as therapeutic, a form of transformation that arises not from the analysis of past trauma, but from the training of the individual’s spontaneity based on the analysis of his present behavior.”
