In this interactive webinar, Christoffel Sneijders (MCC coach, therapist, professor and founder of 3 Brains Intelligence) presents findings from over 5,200 administrations of his 3‑Brains dominance test. He explains the three‑brain model (head, heart, gut), shows how brain‑dominance patterns differ between coaches, middle managers, senior leaders and C‑suite executives, and links these patterns to McKinsey’s four leadership behaviours, Paul Zak’s trust factors and Lencioni’s five team dysfunctions. The session highlights that most leaders over‑rely on head‑brain logic, under‑use gut‑brain confidence, and that coaches tend to be heart‑brain dominant. Sneijders argues that balanced activation of all three brains – especially developing gut‑brain trust – is the missing ingredient in most development programs. He proposes a four‑pillar coaching approach (3‑brain baseline, trust‑factor work, somatic awareness, metacognition) and offers practical tools, cultural/gender insights, and a call to action for participants to take the free test and join further training. The latter part of the webinar focuses on practical coaching applications: using language cues to identify a client’s dominant brain, employing embodiment and mirror‑neuron awareness to sense client states, recognizing the risks of single‑brain (especially gut‑dominant) leadership that can become toxic, and applying situational leadership by flexibly prioritising the head, heart or gut depending on context. Participants share reflections on the framework’s relevance, confirming its value for entrepreneurs and leaders seeking balanced decision‑making.
