FIRO (Schutz)
Inclusion, Control, Affection
Will Schutz (1958, "FIRO: A Three-Dimensional Theory of Interpersonal Behavior") proposed that relationships are driven by three interpersonal needs: Inclusion (belonging and being part of things), Control (influence and responsibility) and Affection (closeness and warmth). Each need varies in how much we express it and how much we want from others. ScanMyLove estimates the expressed-versus-wanted balance for each need from the conversation to explain compatibility and tension.
What ScanMyLove measures:
Inclusion/control/affection needs, expressed vs wanted.
Understanding the model
Will Schutz (1958, "FIRO: A Three-Dimensional Theory of Interpersonal Behavior") proposed that relationships are driven by three needs: Inclusion (belonging), Control (influence and responsibility) and Affection (closeness). Each need has an expressed side (how much we initiate) and a wanted side (how much we want from others).
The three FIRO needs
| Need | Low expression | High expression |
|---|---|---|
| Inclusion | Keeps to self, few invitations | Seeks togetherness, makes plans |
| Control | Defers, avoids decisions | Takes charge, organizes, directs |
| Affection | Reserved, slow to warm | Initiates closeness and warmth |
How ScanMyLove applies it
ScanMyLove estimates the expressed-versus-wanted balance for each need from the conversation — who seeks togetherness, who takes charge, who initiates warmth — to explain compatibility and friction.
What the report reveals
A report might show one partner high in "wanted inclusion" (needs to feel part of plans) paired with one low in "expressed inclusion" (rarely initiates) — a recurring source of feeling left out.
Frequently asked questions
What does FIRO stand for?
Fundamental Interpersonal Relations Orientation — Schutz’s theory that inclusion, control and affection drive how we behave in relationships.
What is the expressed vs wanted distinction?
Expressed is how much of a need you show toward others; wanted is how much you want from them. Mismatches (e.g. high wanted, low expressed) create tension.
Is FIRO still used?
Yes — the FIRO-B assessment is widely used in coaching and team development. ScanMyLove applies the framework as a practical lens, not a formal test.
