Andy describes how repeated shocks from the global financial crisis through Brexit, COVID, the cost-of-living shock and geopolitical uncertainty, that have “scarred” institutions and fueled caution that weakens growth, echoing Keynes’s paradox of thrift. Reflecting on decades at the Bank of England, Haldane frames crises as moments when the Overton window opens for lasting reform, shaped by early experience of the 1992 ERM exit and teenage exposure to 1980s recession. He argues robust solutions to complex problems are often simple, emphasizes active listening as a core leadership skill, and highlights influences from small-business owners. He calls the UK’s central challenge a major reimagining of schools and skills to tackle economic inactivity, guarantee pathways to apprenticeships or degrees, and share leadership across sectors. 00:00 Meet Andy Haldane 00:29 Cross Sector Leadership 02:25 Scarred By Crises 04:55 Crisis As Opportunity 08:44 Early Leadership Spark 12:28 Climbing Big Mountains 14:55 Introvert Strengths 20:09 Metaphors And Listening 27:52 Governors And Advice 31:41 Carney and Brexit 34:03 Career Growth Beyond Banking 35:57 Outrider Thinking and Cross Discipline 38:20 Pro Bono Economics and Leaving 39:50 Sustainable Work and Creativity 44:14 Skills Gap and Opportunity 47:12 Reimagining Schools and Training 50:49 Leadership as Team Sport 52:41 Speed Round and Wrap Up Subscribe to not miss an episode! ▶️ Credits: Producer: Sunny Winter Producer: Thuy Dong Producer: Jimmy McLoughlin OBE Learn more about your ad choices.

What Negotiating With Putin & Gaddafi Taught Me About Leadership | Lord John Browne
Lord John Browne on Engineering Thinking, Leading BP, Climate Risk, Negotiating Putin & Coming Out in Business | What We Don’t Know Welcome to What We Don't Know with Matt Brittin & Hayaatun Sillem.  Matt Brittin is the former President at Google EMEA. After 18 years at one of the world's biggest companies, he stepped down, took a gap year, and recently became the Director General of the BBC. Dr. Hayaatun Sillem spent a few years leading the Royal Academy of Engineering and was awarded the Queen Elizabeth Prize for Engineering.  This is the show about better leadership in a truly chaotic world.  Across the series, episodes are joined a range of other leading figures, bringing different perspectives to each conversation. Subscribe to not miss an episode! ▶️ ⚡️ Powered by Boxlight.io https://www.boxlight.io/ ------ In this episode of What We Don’t Know, Hayaatun and Matt sit down with Lord John Browne. He discusses how he describes himself as a businessman, author, and above all an engineer, explaining how engineering training shaped his systematic approach from writing to boardrooms and science.  He reflects on childhood habits of dismantling clocks, the importance of proper tools, and his early life at King’s School Ely and Cambridge, influenced by a soldier father and a Holocaust-survivor mother who stressed self-sufficiency and looking forward.  Browne recounts joining BP in 1966, learning about unions and refinery work, and formative engineering experience on Alaska’s North Slope, including early computer optimization work. He describes leadership lessons from Stanford Business School—purpose, inclusion, listening, and negotiation—and his path to becoming BP CEO in 1994, reorganizing BP around customer-oriented business units, and addressing climate risk through internal analysis, methane reduction, carbon pricing, and renewables. He shares negotiation insights from dealings with leaders including Putin, Gaddafi, and others, then explains writing The Glass Closet after being outed in 2007 and arguing for workplace environments where people can be themselves, with safety and pragmatism.  00:00 Intro 01:38 Taking Things Apart 02:50 Joining BP in 1966 03:15 School and Rowing Days 05:06 Parents and Upbringing 07:41 Lessons From His Mother 09:22 Early BP Apprenticeship 11:41 Alaska and First Big Break 15:10 Stanford and Learning Leadership 19:50 Becoming BP CEO 24:18 Rebuilding BP and Climate Wakeup 28:51 Oil And Climate Reality 29:44 Speaking Up On Climate 31:10 Negotiating With Putin 35:39 Hard Lessons In Dealmaking 37:19 Writing The Glass Closet 39:09 Being Outed As CEO 44:05 Inclusion With Pragmatism 45:48 Resilience And Reinvention 50:25 Optimism And Future Tech 52:44 Speed Round And Farewell Credits: Producer: Sunny Winter Producer: Thuy Dong Producer: Jimmy McLoughlin OBE Learn more about your ad choices.

Why The Best Leaders Make Wrong Decisions | What We Don't Know with Matt Brittin & Hayaatun Sillem
Leading Through Uncertainty: Clarity, Vulnerability & Decision-Making in a Chaotic World | What We Don’t Know Welcome to What We Don't Know with Matt Brittin & Hayaatun Sillem. The show about better leadership in a truly chaotic world. Across the series, episodes are joined a range of other leading figures, bringing different perspectives to each conversation. Subscribe to not miss an episode! ▶️ ⚡️ Powered by Boxlight.io https://www.boxlight.io/ ------ In this episode of What We Don’t Know, Hayaatun and Matt explore how leadership must evolve to meet chronic uncertainty, shifting from alpha certainty to humility, adaptability, and earned trust. They discuss why clarity of purpose matters more than false certainty, how strategy can provide agency while leaving room for flexibility, and why leaders need faster shared learning cycles and better “intel” from across their networks. Hayaatun shares how the pandemic forced her to blend personal and professional life, show vulnerability, and finally ask for help when she felt close to unraveling, reframing self-monitoring as being “safe to drive the bus.” Matt Brittin reflects on learning decisiveness in ambiguous choices and describes leading Google’s response in Russia after the Ukraine invasion, prioritizing people’s safety and values. Matt and Hayaatun also answer audience questions on fear, decisiveness, resilience, and admitting “I don’t know.” 00:00 Welcome and theme 01:21 Leadership playbook shifts 02:35 Pandemic as pivot 05:02 Strategy under pressure 06:56 Clarity and agency 09:50 Collaboration and intel 12:59 Sandstorm metaphor 13:57 Vulnerability in public 16:09 Asking for help 19:19 Decisiveness lesson 23:35 Russia Ukraine crisis 27:44 Chronic uncertainty stamina 29:41 Personal boardroom 30:31 Cognitive diversity 31:28 Facing Worst Cases 32:59 Welcoming Dissent 34:06 Admitting Not Okay 35:26 Peer Support Breakthrough 39:18 Safe to Drive Bus 40:18 Asking for Help 41:21 Leadership Inspiration 42:23 Learning Model Mentors 44:03 Books Beyond Leadership 45:07 Zak Brown Authenticity 47:51 Dystopian Leadership Lessons 50:25 Sleep as Leadership Fuel 51:57 Audience Questions Rapidfire 53:21 Decisive Versus Right 54:33 Resilience Not Denial 55:17 Leading Without Answers 56:43 Beyond Crisis Identity Credits: Producer: Sunny Winter Producer: Thuy Dong Producer: Jimmy McLoughlin OBE Learn more about your ad choices.

Ex John Lewis Boss: Why The Best Leaders Are Impossible to Read | Sharon White
Welcome to What We Don't Know with Matt Brittin & Hayaatun Sillem. The show about better leadership in a truly chaotic world. Across the series, episodes are joined a range of other leading figures, bringing different perspectives to each conversation. Subscribe to not miss an episode! ▶️ ⚡️ Powered by Boxlight.io https://www.boxlight.io/ ------ This week, Hayaatun is joined by Jimmy McLoughlin OBE, host of ⁨@jimmysjobs⁩ , to welcome Baroness Sharon White. Sharon White traces her journey from a working-class East London childhood — daughter of Windrush generation parents who left school at 11 and 14 — through 26 years as one of Whitehall's most senior but deliberately invisible civil servants, to leading OFCOM and later the John Lewis Partnership through COVID and financial turbulence. She shares why being impossible to read became a strategic asset, how the insider/outsider experience of growing up as a minority shaped her willingness to hold unpopular positions, and why she believes the problems facing political leaders today are categorically harder than a generation ago. She reflects on what it takes to lead 80,000 partners through a democratic business structure unlike anything in the private sector, why a reluctant regulator is a better regulator, and how to tell the difference between noise and what's actually real when everything feels urgent. She also discusses building crisis-ready teams before the crisis hits, the leadership skill she thinks nobody talks about enough — and what her teenage son taught her about inclusion. Timestamps: 00:00 Intro 01:38 Introducing Sharon White 03:56 What To Expect Today 04:30 Backstage At Number 10 06:53 Politics In The Social Media Age 08:36 Childhood And Immigrant Roots 13:43 Finding Her Voice 20:02 Purpose Across Career Switches 29:03 Earning Trust In New Worlds 32:50 Becoming Public Facing 36:40 Reluctant Regulator Mindset 40:28 Partnership Democracy Model 41:12 Customer Love and Stakeholders 43:20 Employee Ownership Pride 45:25 Resilience and Gratitude Mindset 47:30 Growth Needs Brave Leadership 51:12 Leading Through Constant Crises 53:07 Parenthood and Inclusion Lessons 56:18 Bravery and De Klerk Story 59:05 Quickfire Leadership Questions 01:01:33 Hosts Reflect on Key Takeaways 01:07:33 Duolingo Taxi Hiring Test 01:11:54 Meta AI Leader Avatars Debate 01:14:12 Wrap Up and Stay Connected Credits: Producer: Sunny Winter Producer: Thuy Dong Producer: Jimmy McLoughlin OBE Learn more about your ad choices.
