THE REAL PROBLEM
You know what to do.
So why aren't you doing it?
Most solutions only work on one brain. Yours has 3, and 2 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 keep people-pleasing
Your Heart fears rejection so it says yes — but without your Head's clarity, you can't hold a boundary.
You push until you crash
Your Gut drives relentlessly forward — but without your Heart's warmth, you burn out alone at the top.
You stay emotionally distant
Your Head retreats into logic — but without your Heart's connection, relationships feel hollow.
You swallow what you really feel
Your Heart protects harmony — but without your Gut's assertiveness, your truth never gets said.
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.
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.
Step 1 - The foundation
The 3 Brains Dominance test
Every decision you make — every reaction, every relationship pattern — starts in one of three biological intelligence centres. This test reveals which one leads when you're not consciously choosing. And why that matters more than you think.
-
Know your automatic decision pathway — the brain that leads before you even think about it
-
Understand your natural strengths — and the blind spots that come with them
-
See why you repeat the same patterns — in work, relationships, and under pressure
-
Get a personalised profile — one of 25+ combinations with specific growth insights
-
Learn the 3 questions that align Head, Heart and Gut before any important decision
Step 2 - The deeper layer
The 12 Protectors Test™
Even if you know your dominant brain — context can override it. A situation triggers a hidden belief, and suddenly you're not who you thought you were. The Protectors Test reveals which of 12 protective strategies is running your stress, your reactions, and your stuck points.
-
Identify your 4 most active Protectors — the inner patterns driving overthinking, over-giving, over-pushing
-
Understand the core belief behind each one — what your system is really trying to protect you from
-
Discover the hidden gift in every Protector — your stress response contains a superpower
-
See exactly why change hasn't stuck — and what to do differently
-
Receive a personalised written report by email with your full Protector profile

Discover Your Dominant Brain
5 minutes. Find out which of your 3 Brains leads automatically — Head, Heart, or Gut — and what that means for your decisions and behaviour.
Uncover Your Protectors
10 minutes. Find out which hidden beliefs can override your dominant brain — and why you sometimes behave in ways that don't reflect who you truly are.
Align All Three
You now have a complete inner map. Head, Heart, and Gut working together — making decisions that feel clear, grounded, and right in your mind, body, and soul.
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 · Values · Belonging · Relationships
When overdominant: People-pleasing · Blurred boundaries · Burnout · Avoiding conflict
❤️
Gut Brain — The Driver
✦ Drive · Instinct · Decisiveness · Action
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.
HEART DOMINANT · GUT QUIET
The Warm Connector
You build extraordinary relationships — but struggle to hold firm boundaries. You feel everything deeply. Saying no feels like rejection.
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.
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 + 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 + 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 TESTS
From self-aware to self-leading
Then discover what holds you back.
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.
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.
Sustainable energy and drive
Stop exhausting yourself proving, pleasing, or performing. Lead from genuine strength instead of from the fear of not being enough.
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.
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.
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.
