The Divided Brain: Understanding Human Behaviour in Branding and Business (Unabridged‪)‬

Help Make Sense of What Doesn’t Make Sense

This isn’t just a book about branding—it’s a guide to the hidden operating system behind human behaviour.

The Divided Brain introduces a powerful metaphor rooted in neuroscience: our minds are driven by two distinct but interlocking systems—the fast, emotional Old Brain and the slower, rational New Brain. Every decision your customers make, every instinct your team follows, and every reaction you encounter in a negotiation or pitch stems from the tension between these two mental gears.

Once you learn to spot which brain is in control, the fog lifts. What once seemed irrational becomes understandable. Sudden client reversals, hesitations in sales calls, or why one brand sticks while another flops—it all starts to make sense.

Inside, you'll learn how to:

Decode emotional vs. rational behaviour in business settings
Use neuroscience-backed strategies to improve branding and marketing
Craft messages that move people—beyond logic
Apply behavioural science in leadership, sales, and team dynamics


Blending insights from behavioural psychology, marketing, and over four decades of real-world brand strategy, The Divided Brain offers a practical lens for understanding people—not in theory, but in boardrooms, campaigns, workshops, and high-stakes conversations.

By the final chapter, you won’t just understand how the brain works—you’ll use that insight to lead smarter, connect deeper, and build brands that truly resonate.
