Why do you think, feel,
and act the way you do?
The answer is not in your mindset. It's in your biology.
Two free tests — 15 minutes total — that reveal more about how you make decisions, relate to others, and lead your life than years of self-help books combined.
THE REAL PROBLEM
You know what to do.
So why aren't you doing it?
Most solutions only work on one brain. Yours has three — and two of them aren't being asked.
You overthink decisions
Your Head keeps analysing because it fears being wrong — but without your Gut's courage, you never move.
You stay emotionally distant
Your Head retreats into logic — but without your Heart's connection, relationships feel hollow.
You keep people-pleasing
Your Heart fears rejection so it says yes — but without your Head's clarity, you can't hold a boundary.
You swallow what you really feelY
our Heart protects harmony — but without your Gut's assertiveness, your truth never gets said.
You push until you crash
Your Gut drives relentlessly forward — but without your Heart's warmth, you burn out alone at the top.
You perform instead of connecting
Your Gut projects confidence — but without your Heart's vulnerability, no one really knows you.
These aren't personality flaws. They are predictable patterns that emerge when your 3 Brains are out of alignment — when one leads without the other two. The tests reveal exactly which brain is dominating and what's holding the others back.
TWO TESTS. ONE COMPLETE PICTURE
Start with what drives you.
Then discover what holds you back.
Each test reveals a different layer of your inner system. Together, they give you a complete map.
THE RECOMMENDED PATH
Two tests. One transformation.
Take them in order for the most powerful insight. Each one deepens what the other reveals.
WHAT THE DOMINANCE TEST REVEALS
There are 25+ unique brain profiles. Yours is specific to you.
It's not just "Head dominant" or "Heart dominant." The test maps the relationship between all three brains — which leads, which supports, and which is quiet — giving you a nuanced, personalised picture.
Each profile comes with a rich written description: your decision pathway, your strengths, your blind spots, your growth edge, and the 3 questions to ask before any important decision.
Based on 20+ years of research in neuroscience, coaching psychology, and evolutionary biology. Developed by Christoffel Sneijders MCC.
🧠
Head Brain — The Architect
✦ Logic · Strategy · Clarity · Precision · Planning
When overdominant: Overthinking · Perfectionism · Emotional detachment · Analysis paralysis
❤️
Heart Brain — The Connector
✦ Empathy · Trust · Values · Belonging · Relationships
When overdominant: People-pleasing · Blurred boundaries · Burnout · Avoiding conflict
💪
Gut Brain — The Driver
✦ Courage · Drive · Instinct · Decisiveness · Leadership
When overdominant: Reactive · Controlling · Exhausted · Overlooking others
SAMPLE PROFILES - WHICH ONE SOUNDS LIKE YOU?
HEAD DOMINANT . HEART SILENT
The Precise Strategist
You think with exceptional clarity — but others sometimes experience you as emotionally distant. You know exactly what to do. Moving feels risky without certainty.
ALL THREE BALANCED
The Dynamic Adapter
You're remarkably flexible — but hard to predict. You shift between thinking, feeling, and acting fluidly. The challenge: choosing consciously which brain to lead with.
HEART DOMINANT . GUT QUIT
The Warm Connector
You build extraordinary relationships — but struggle to hold firm boundaries. You feel everything deeply. Saying no feels like rejection.
HEART + HEAD . GUT LOWER
The Thoughtful Empath
You combine deep empathy with intellectual clarity — but delay decisive action. You understand everything. Moving powerfully in uncertainty is the growth edge.
GUT DOMINANT . HEAD SUPPORTIVE
The Decisive Executor
You move with conviction and courage — but sometimes push too hard. You're most alive when progress is being made. Slowing down feels like falling behind.
GUT + HEART . HEAD LOWER
The Passionate Leader
You act with conviction and care deeply — but sometimes miss strategic details. Your leadership is inspiring. Analytical patience is where alignment grows.
WHAT CHANGES AFTER THE TEST
From self-aware to self-leading
Taking both tests gives you something rare: a complete, nuanced picture of your inner decision-making system — and a clear path forward.
🎯
Decide without second-guessing
When you know which brain is speaking — and whether the other two agree — decisions become clear and grounded instead of agonising
🗺️
A map — not a label
This isn't a personality type that defines you. It's a living map of how your system works right now — one you can change.
🤝
Relationships that feel real
Understand exactly why you over-give, withdraw, or push — and finally show up as yourself without fear of rejection or disapproval.
🔓
The hidden gift in every pattern
Every Protector has a cost and a superpower. Every brain dominance has a strength and a shadow. Discover both — and use them.
⚡
Sustainable energy and drive
Stop exhausting yourself proving, pleasing, or performing. Lead from genuine strength instead of from the fear of not being enough.
🌱
Change that actually sticks
Because you're finally working with all three brains — not just the one that reads books and makes action plans.
❝ When your Head brings clarity, your Heart brings meaning, and your Gut brings courage — your system stops pulling in different directions. That is where alignment begins.
