The Science Behind Our Approach
The Success Evolution Institute’s work is grounded in established research on the autonomic nervous system, Polyvagal Theory, and organizational psychology. We translate this science into practical application for leaders and organizations.
Below are the core frameworks that inform our programs.
The S.T.A.T.E. Framework
Recognize what is happening in your body before your mind catches up. You cannot regulate what you cannot sense.
Identify your patterns, triggers, and warning signs over time. Single moments deceive; patterns reveal.
Understand how your nervous system state affects everyone around you. Your state is contagious. You are the weather system others navigate.
Access the version of yourself each moment requires. You contain multiple selves; state determines which one shows up.
Build lasting capacity so regulation becomes your default. What you practice becomes what you default to.
This framework is formally presented in “Regulating the Forecast: An Interoceptive Predictive-Processing Framework for Self-Regulation Under Pressure (the S.T.A.T.E. Model),” currently under peer review at Frontiers in Psychology (see Our Published Research below).
The Biological Substrate: The Three Autonomic States
Leadership capacity is grounded in three autonomic nervous system states identified in Polyvagal Theory, each with a distinct physiological signature.
Physiological safety, prefrontal clarity, relational attunement, and optimal allostasis.
Metabolic mobilization, acute stress arousal, tunnel vision, and cognitive narrowing.
Metabolic conservation, executive exhaustion, allostatic overload, and behavioral withdrawal.
The Applied Executive Architecture: The Leadership Capacity Cycle
The Leadership Capacity Cycle is the Institute’s proprietary applied model, mapping the three-state biological substrate above onto five executive phases leaders move through under real operational conditions.
- Expansive (Ventral Vagal Anchor): High strategic vision, psychological safety, and collective co-regulation.
- Tensive (Early Sympathetic Mobilization): Elevated cognitive load, focused operational pressure, and rising metabolic demand.
- Defensive (Reactive Sympathetic): Threat-rigidity, conversational defensiveness, cognitive inflexibility, and friction.
- Destructive (Sympathetic Overload / Dysregulation): Decision failure, acute burnout, relational breakdown, and operational error.
- Pensive / Recovery (Dorsal Vagal Recalibration): Restorative introspection, nervous system downshifting, and capacity rebuilding.
The goal is not to remain in Expansive at all times. It is to recognize a shift early, understand its mechanism, and return to Expansive deliberately rather than by default.
Foundational Research
Our work builds on established research including:
- Polyvagal Theory (Stephen Porges): the autonomic nervous system’s role in social behavior and emotional regulation.
- Interoceptive predictive processing: how the brain forecasts bodily state, and how that forecast shapes perception and decision-making under pressure.
- Organizational psychology: how individual nervous system states create collective organizational patterns.
- Embodied cognition: the role of the body in shaping thought, decision-making, and behavior.
Our Published Research
The Institute’s research is conducted through its research arm, the Human Performance Research Lab in Fresno, California, led by Dr. Joshua McWealth Unamba.

The State Regulation Capacity Scale (SRCS): Construct Definition and a Validation Agenda for a Body-First Model of Self-Regulation
The Anchor Need Profile (ANP): Construct Definition and a Validation Agenda for a Three-Need Model of Interpersonal Sensitivity Under Stress
All three are preprints published on Zenodo. Two are currently under peer review at Frontiers in Psychology. The Anchor Need Profile is a preprint only, with no peer-review claim.
Bridging Research and Real-World Application
At the Success Evolution Institute, we study how nervous system state shapes decision-making, resilience, and performance under pressure, and we translate that research into practical application for leaders and organizations operating in high-stakes environments.
