Most of us believe we make rational choices, but our brains are actually wired to say no before we ever get to the logic. Paul Larche, a Hall of Fame broadcaster and author of The Divided Brain, spent four decades in media before turning to neuroscience to find out why customers actually buy. He joins the show to break down the Old Brain versus New Brain metaphor and explain how leaders can stop accidentally triggering the wrong response in their brand storytelling.

About Paul Larche

Paul Larche is a Hall of Fame broadcaster and media pioneer who spent nearly fifty years building a radio empire from the ground up. After starting as a teenage announcer and eventually owning multiple stations, he became obsessed with why some advertising failed while other campaigns lasted decades. This led him deep into the study of behavioral psychology and neuroscience, culminating in his award-winning book, The Divided Brain. Today, Paul translates complex brain science into actionable business strategies, helping leaders bridge the gap between technical expertise and the emotional drivers that actually compel people to take action.

What Brand Has Made Paul Smile Recently?

Paul finds himself smiling at legacy brands like McDonald’s that have successfully weathered decades of change by continuing to speak to the heart rather than the head. He admires how these organizations prioritize universal human feelings and lifestyle over technical product features, proving that compelling storytelling remains the most effective way to maintain brand gravity over the long term.
