    The Rest is Evidence: How Evidence Shows What Really Works with Helen Pearson

    Most of us like to think our decisions are grounded in facts. Whether it’s in medicine, business, or everyday life, we assume the “best” option rises to the top through clear evidence. But for most of history — and even today — that hasn’t really been the case. In this episode, I talk with science journalist Helen Pearson, author of Beyond Belief: How Evidence Shows What Really Works, about the surprisingly recent rise of evidence-based thinking, why it transformed fields like medicine, and why it still struggles to take hold in others. We discuss how doctors once relied more on authority than data, why a single study can be misleading, and how systematic reviews became the gold standard for figuring out what actually works. Helen also explains how these ideas have spread into social policy and business — with mixed success — and why human nature often resists evidence, even when it’s right in front of us. Along the way, we get into how to spot bad claims, why misinformation spreads so easily today, and how you can become a sharper, more evidence-minded thinker in your own life. Show Highlights Why evidence-based medicine is a surprisingly recent developmentThe two pioneers who helped change how doctors make decisionsWhat was wrong with the old “eminence-based” approachWhy one study rarely tells you the truthWhat a systematic review is and why it mattersHow the Cochrane Collaboration helps doctors cut through information overloadThe challenge of dealing with millions of new studies every yearWhat COVID revealed about our evidence systems under pressureHow evidence-based thinking moved into social policy and reduced povertyWhy most policies and programs still aren’t properly testedThe problem with “HIPPOs” (Highest Paid Person’s Opinion) in businessWhy management is especially vulnerable to fads and trendsHow AI is both helping and complicating scientific researchWhy evidence alone isn’t enough to make decisionsHow to teach kids (and yourself) to spot bad claimsSimple “evidence hacks” you can use in everyday lifeResources Related to the Podcast Beyond Belief: How Evidence Shows What Really Works by Helen PearsonThe Cochrane CollaborationHelen PearsonIf you’re looking to make better decisions — in your work, your health, or your everyday life — this episode will give you a clearer lens for separating what works from what just sounds good.

    A Little History of The Earth in 45 Minutes: Jamie Woodward

    How do you tell the story of 4.5 billion years of Earth’s history in a way that’s engaging and easy to understand? In this episode, I talk with Jamie Woodward, Professor of Physical Geography at the University of Manchester about his book A Little History of the Earth. Jamie explains how scientists piece together the planet’s deep past—from the formation of the universe to the shifting of continents, the age of dinosaurs, and the powerful forces that have shaped our landscapes. We discuss why Earth has always been a dynamic planet, how short “bite-sized” chapters can make big history accessible, and what studying deep time can teach us about today’s environmental challenges. If you’re curious about geology, natural history, and the story of our planet, this episode offers a fascinating introduction to Earth’s epic past. 🌍 Highlights From Our Conversation Why Jamie chose to tell the story of Earth through short, bite-sized chaptersHow scientists reconstruct events that happened billions of years agoThe dramatic forces that shaped Earth: plate tectonics, volcanoes, ice ages, and asteroid impactsThe rise and fall of the dinosaursHow rivers, glaciers, and oceans sculpt the landscape we live inWhy Earth’s climate has changed dramatically throughout historyThe concept of the Anthropocene — and why humans are now a geological forceHow learning Earth’s story can make us more curious and more responsible about the planet’s future Link to Jamie's Book 'A Little History of The Earth.'
