A clear look at the four modes—where they come from, how they work, and why they’re not personality types but shifting emotional states

What Is the 4-Mode Gradient System?

The 4 Modes of TEG-Blue describe how our emotional system shifts depending on whether we feel safe, threatened, or in control.

The gradient moves: Connection → Protection → Control → Oppression.

These are not personality labels. They are states we move in and out of, sometimes in milliseconds, sometimes for years.

• Connect Mode → When the body detects safety, the nervous system moves into rest, repair, and connection. In this state, we bond, learn, and create.
• Protect Mode → When the body senses danger, the nervous system shifts into vigilance and survival: fight, flight, freeze, or fawn.
• Control Mode → When protection stays switched on too long, defense becomes strategy. People begin using control to feel safe or powerful, bending truth and relationships to avoid accountability.
• Oppressive Mode → At the extreme, empathy shuts down. Power and domination become the goal. Others are treated as tools, not people.

Why the 4-Mode Matters for Understanding Emotions

The Gradient explains:

• Why people who care can still cause harm.
• Why unhealed wounds can quietly distort how we treat others.
• Why “defense” can look like “abuse” from the outside.
• Why power systems reward control and oppression, allowing harm to flourish.

Most importantly: it shows us where repair is possible—and where harm begins.

Nervous System Roots of the 4 Modes (Polyvagal Connection)

The first two modes are biological instincts:

• Connect → Parasympathetic system (ventral vagal). Regulated, empathic, collaborative.
• Protect → Sympathetic system (fight/flight/freeze/fawn). Threat-reactive, self-protective.

The other two modes are learned extensions of defense:
