The Blueprint for how Decisions are Actually Made.

The Divided Brain introduces a simple yet powerful metaphor rooted in neuroscience: our minds are driven by two distinct but interlocking gears. 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 stems from the constant tension between these two mental gears.

He later founded Larche Communications Inc., transforming a visionary startup into a major media force with five radio stations and a marketing and branding agency. Under his leadership, his radio stations earned 28 industry awards before being acquired in successful strategic sales to Rogers Media, Bell Media and Treefrog. In 2019, he was inducted into the Ontario Association of Broadcasters Hall of Fame in recognition of his lasting impact on Canadian media.

Is This Book For You?

This book isn’t a textbook on neuroscience or behavioural psychology—it’s a practical metaphor designed to simplify those complex ideas. If you’re looking for academic depth or peer-reviewed theory, this likely isn’t for you.But if you want a clear, accessible way to understand what actually drives decisions in business and life, The Divided Brain delivers.

Marketers & Branders

If you’re tired of campaigns that sound great in theory but flop in the real world, this book helps you understand what truly drives decisions—emotion, not logic—and how to craft messages that resonate at a primal level.

Business Owners & Entrepreneurs

You don’t need a marketing degree to create a brand that resonates. The Divided Brain provides business owners and entrepreneurs with the tools to decode customer instincts, clarify their value, and communicate in ways that stick.

Startups & Founders

When every dollar counts and attention is scarce, understanding how people really think is your unfair advantage. This book distills behavioural science into practical tools that help you build trust, traction, and loyalty from day one.

Curious About How We Think

This book explains why intelligent people sometimes make irrational decisions and how understanding the human mind can help you personally and professionally.

Not affiliated with Iain McGilchrist’s academic work, this book uses “The Divided Brain” as a behavioural metaphor, focusing on how emotional and rational systems shape branding, leadership, and everyday choices.
