About

Hosted by Dr Angela Lewis, a former CIA intelligence officer and senior intelligence leader, The Unknown Knowns explores what happens when intuition meets tradecraft — when the data ends and genuine insight begins. Drawing on a career spent working at the heart of intelligence and decision-making, Angela explores how we sharpen judgement, confront bias and make sense of complexity. From cognitive blind spots and negotiation to influence and communication, each episode brings lessons from the world of intelligence to the decisions we make every day — helping us think better, lead smarter and communicate with greater impact.
