The 14 Principles of Change
The invisible architecture shaping every case, now made visible.
These are not beliefs. Not styles. Not techniques.
They are non-optional conditions for sustainable behaviour change — observed across species, systems, and interventions.
You’ve been using them, even without naming them.
Until now, they lived in pieces: scattered across modalities, buried in instinct, or held quietly in the work of seasoned practitioners.
This is the first time they’ve been brought together — unified, open, and accessible — to serve as a shared reasoning structure for complex behavioural care.
The 14 Principles
Each principle below reflects a specific and testable condition required for lasting change. In the CNSS model, these are not guidelines — they are natural laws grounded in neuroscience, systems theory, and practitioner casework.

-
Behaviour Is a Result — Not a Starting Point
-
The Human System Is a Change Lever
-
Neurobiological Feedback Loops Are Modified
-
Change Requires Shared Meaning and Commitment
-
Real-World Application Is Required
-
Behaviour Change Is Phase-Based, Not Linear
-
Insight Must Translate to Practice
-
Time Is a System Variable and Must Be Respected
-
Growth Has Limits—And They Must Be Respected
-
Emotional Availability Anchors Change
-
Interventions Adapt to System Feedback
-
Behaviour Change Must Be Tracked Through System Conditions
-
System Stability Depends on Co-Regulation, Not Just Independence
-
Boundaries Contain and Sustain Change
What now?
You can read these principles. You can recognise them.
But to really see where they’re active, fragile, or missing in your practice (or a case) — that takes structure.
The Professional Practice Assessment offers exactly that.
It gives you a lens, a scoring system, and examples that clarify where your system is already aligned … and where subtle breakdowns might be occurring.
