Fundamental Interpersonal Relations Orientation (FIRO) is a theory of interpersonal relations, introduced by William Schutz in 1958. This theory mainly explains the interpersonal interactions of a local group of people. The theory is based on the belief that when people get together in a group, there are three main interpersonal needs they are looking to obtain – affection/openness, control and inclusion. Schutz developed a measuring instrument that contains six scales of nine-item questions, and this became version B (for "Behavior"). This technique was created to measure how group members feel when it comes to inclusion, control, and affection/openness or to be able to get feedback from people in a group. Description These categories measure how much interaction a person wants in the areas of socializing, leadership and responsibilities, and more intimate personal relations. FIRO-B was created, based on this theory, as a measurement instrument with scales that assess the behavioral aspects of the three dimensions. Scores are graded from 0–9 in scales of expressed and wanted behavior, which define how much a person expresses to others, and how much he wants from others. Schutz believed that FIRO scores in themselves were not terminal, and can and do change, and did not encourage typology; however, the four temperaments were eventually mapped to the scales of the scoring system, which led to the creation of a theory of five temperaments. Schutz himself discussed the impact of extreme behavior in the areas of inclusion, control, and openness as indicated by scores on the FIRO-B (and the later Element-B). For each area of interpersonal need the following three types of behavior would be evident: (1) deficient, (2) excessive, and (3) ideal. Deficient was defined as indicating that an individual was not trying to directly satisfy the need. Excessive was defined as indicating that an individual was constantly trying to satisfy the need. Ideal referred to satisfaction of the need. From this, he identified the following types: Schutz composed a "Matrix of Relevant Interpersonal Data", which he called "The Elephant". Each area consisted of a smaller matrix of "act" and "feel" by "Self to Other" (Action), "Other to Self" (Reaction), and "Self to Self". "Act" and "Feel" divided the rows, which were: "Desired Interpersonal Relations (Needs)", which denoted "satisfactory relations" in each area; "Ideal Interpersonal Relations" is what would correspond to "moderate" expressed and wanted scores; "Anxious Interpersonal Relations" was subdivided into rows of "Too
