Group analysis posits that human beings are fundamentally social beings whose lives are inextricably linked with others in manifold ways. The source of our personal dilemmas can be found in the groups in which we are situated, across time and throughout our development. These groups include family, school, work, and so on. Because an individual's difficulties first develop in groups, these difficulties are then best explored, understood, and changed specifically in a group environment. For group analysts, an individual does not exist apart from and outside of a social context.

"Free floating discussion" (the group equivalent of free association in psychoanalysis) allows members to talk at their own pace about what's bothering them.

Group Analysis is an established form of psychotherapy, at least as powerful as individual treatment. In addition to group and individual behavior, it also offers a way of thinking about and understanding group dynamics. Therefore, group analytic techniques can be successfully applied in professional supervision (individual, staff support groups, and organizational consultancy), as well as in couples and individual therapy.
