What C-Suite Leaders Have That Middle Managers Don't — Data from 5,218 Tests | 3 Brains Intelligence

In this webinar Christoffel Sneijders presents data from his Three‑Brain Intelligence test, administered to 5,218 leaders across 15 languages and multiple cultures. The test measures the relative dominance of three decision‑making systems – the head (logical), heart (emotional/social), and gut (instinctual) brains – and assigns a score for each. By comparing scores of middle managers, senior managers, and C‑suite executives, Sneijders uncovers systematic differences: C‑suite leaders show lower head‑brain dominance and higher gut‑brain dominance than middle managers, while heart‑brain scores remain relatively stable across levels. He links these patterns to McKinsey’s research on four core leadership behaviors (problem‑solving, results orientation, seeking diverse perspectives, and supporting others) and to Paul Zak’s “trust factor,” arguing that a strong gut‑brain (self‑confidence, willingness to act on incomplete data) underpins trust, engagement, and performance. The presentation also explores demographic variations (gender, cultural baselines, industry), statistical significance (p‑values ~0.0009 for head, 0.88 for heart, 0.0009 for gut), and practical implications for coaching and development: training for gut‑brain activation, metacognitive awareness, vulnerable confidence, and somatic practices. Sneijders critiques conventional emotional‑intelligence programs as incomplete, proposes a four‑pillar development model (brain awareness, trust factor, somatic embodiment, metacognition), and offers concrete tools (risk‑with‑reversible‑consequences, mindfulness, role‑play) to shift leaders toward a more balanced three‑brain profile.
