The short version
How Decision IQ reads a decision
Decision IQ is built on the 6BRAINS framework — a working map of the six systems that decide for you before you think you've decided. This page is the overview. The mechanics live in the library.
Six systems, one decision
Every choice is voted on by six systems at once. A pitch that fails your logic can still pass through your instincts, your need to belong, or your body's fatigue.
Influence targets the unwatched one
Persuasion rarely argues with the brain you're consciously using. It speaks to the one you aren't auditing — which is why smart people get moved by weak arguments.
Exposure is measurable
From how you describe a real situation, Decision IQ reads which systems are carrying the decision, and scores how open each one is right now.
Defense is specific
Each finding comes with a named mechanism, a mental model, something to do in the next 24 hours, and a tripwire for next time.
The six brains
Reptilian
Threat & scarcity reflexes
Safety, urgency, energy conservation
Mammalian
Belonging, status & authority pull
Trust, peer proof, standing in the group
Rational
Logic traps & false certainty
Evidence, comparison, trade-offs
Enteric
Neurochemical state & the gut–brain axis
Serotonin, dopamine, cortisol, hunger, sleep debt, interoception
Somatic
Procedural memory & motor learning
Trained routines, reflex sequences, muscle memory, embodied habit
Cultural
Identity, mimetic desire & in-group pressure
Meaning, norms, who you believe you are
The golden rule: ignore one brain and the decision meets friction. Manipulation simply engages the brain you left unguarded.
