Introducing The Unknown Knowns, a new podcast hosted by Dr Angela Lewis, former CIA intelligence officer and Sibylline’s Senior Training Advisor.
Drawing on decades of frontline experience, Angela explores how real-world decisions are made when data is incomplete, stakes are high, and judgment carries consequences. Each episode examines the interplay of bias, intuition and experience — and how to sharpen that instinct into disciplined, actionable tradecraft.
Designed for intelligence professionals, senior leaders and decision-makers operating in uncertainty, The Unknown Knowns goes beyond theory to unpack how thinking holds up under pressure.
For our inaugural episode, we begin with one of the most overlooked drivers of decision-making:
Episode 1: The Bias Blind Spot
Before you make a decision, bias has already made part of it for you.
This first episode breaks down why bias isn’t a flaw—it’s a feature. The real risk is leaving it unexamined. Listen now and start turning instinct into disciplined judgment.
