Brian Crombie Radio Hour - Epi 1676 - The Divided Brain: Why We Decide Emotionally and Judge Others Too Quickly

On The Brian Crombie Hour, Brian explores the fascinating science behind human behaviour, decision-making, and the stories that shape who we become.Brian is joined by Paul Larsch, author of The Divided Brain: Understanding Human Behavior in Branding and Business, for a thought-provoking conversation about psychology, neuroscience, marketing, leadership, and why humans often make decisions in ways we don’t fully understand.Paul introduces his concept of the “divided brain”—the ongoing interaction between our emotional, intuitive “old brain” and our logical, analytical “new brain.” Drawing on behavioural economics, neuroscience, and decades of marketing experience, he explains why emotions often drive our choices first, while our rational minds create explanations afterward.The conversation explores how these insights apply to business, politics, leadership, and everyday life. Brian and Paul discuss why familiarity builds trust, how cognitive biases influence decisions, and why organizations that understand human psychology often succeed where those relying only on data and logic fall short.Paul shares examples from the worlds of branding, business, radio, and marketing—including lessons from companies such as Amazon and the famous Tropicana packaging mistake—to demonstrate how understanding human behaviour can shape stronger brands and better leadership.In his closing commentary, Brian reflects on a powerful idea: behind every behaviour is a biography.He explores why people can be quick to judge others without understanding the experiences, relationships, struggles, and successes that shaped them. Anxiety, defensiveness, withdrawal, compassion, and confidence often have stories behind them that remain invisible to the outside world.Brian argues that greater curiosity about someone’s journey can transform judgment into empathy, and conflict into understanding.A meaningful conversation about the psychology of decision-making—and a reminder that becoming better leaders, partners, and citizens begins with understanding human nature and the lives behind the behaviours we see.
