The Human Risk Podcast

What if understanding regulation could help us spot when politicians are promising the impossible? Regulation sounds simple in theory. Something poses a risk, so we create rules and a regulator to control it. In practice, things get complicated very quickly. It's something we all benefit from, but equally can experience as redtape that prevents us from doing what we think we ought to be able to.

On this episode, I'm exploring the inner workings of regulation; so whether you are a regulator, a compliance officer, work in a regulated industry or just a member of the public, this'll help you understand what is and isn't possible and why regulation can often seem ineffective or overbearing.

Episode summary
My guests on this episode are Lyndon Nelson and Gavin Stewart, two highly experienced former financial regulators and authors of Building Better Regulators: The Art of the Impossible.

Regulators are expected to protect consumers, maintain stability, encourage competition, support innovation and increasingly promote economic growth. The problem is that those objectives don't always point in the same direction. As Lyndon and Gavin explain, making trade-offs is part of regulation; pretending those trade-offs don't exist is where things become problematic.

In our conversation, we explore the tension between rules and principles, why firms don't always respond to regulation in the way regulators expect, and how enforcement involves choices about which cases not to pursue. We also look at regulatory perimeters, the hidden costs of collecting data, and why having more information doesn't necessarily lead to better regulation.

We also discuss AI and crypto, behavioural science, consumer protection, international regulation, the temptation to fight the last war, and why regulators need imagination as well as analysis. Ultimately, this is a conversation about regulation as a human system — shaped by incentives, politics, judgement, uncertainty and the behaviour of both regulators and the regulated.

Guest bios
Lyndon Nelson spent 33 years at the Bank of England, much of it working in regulation, and ultimately became Deputy CEO of the Prudential Regulation Authority (PRA). Since leaving the Bank, he has worked with organisations including London Business School and the International Monetary Fund.

Gavin Stewart began his career as a banking supervisor at the Bank of England before moving to the Financial Services Authority (FSA), where he held a variety of senior roles. He later became Chief Risk Officer at the Financial Conduct Authority (FCA) and subsequently worked in the private sector.Together, they are the authors of Building Better Regulators: The Art of the Impossible, a book designed to help regulators — and those who interact with them — better understand the practical realities of regulation.

Episode summary
How can we use AI to become better at persuasion, communication and understanding human behaviour? My guest on this episode is Roger Dooley, author of The Persuasion Engine, a new book exploring what happens when behavioural science meets rapidly evolving technology.

Roger argues that tools once available only to large organisations — from behavioural science expertise to eye-tracking — are becoming accessible to almost anyone. We explore how AI can act as a personal “nudge unit”, helping us apply ideas from behavioural science, test communications and understand how different audiences might respond.We also discuss why simply asking an AI for an answer isn't enough, how to push LLMs beyond predictable responses, and why human judgement remains essential.

Roger introduces his idea of a “60-second audit” — using AI to identify how communications might be misunderstood or backfire before we send them.Along the way, we talk about Cialdini, cognitive biases, invisible calls-to-action, board papers, cultural disasters, AI collaborators, rally driving, long division and why the best analogy for AI might be a power tool rather than a replacement for human thinking.

Guest bio
Roger Dooley is an author, speaker and behavioural science expert who has spent years exploring a deceptively simple question: why do people do what they do?

His latest book, The Persuasion Engine (Wiley, 2026), looks at what happens when behavioural science meets AI — and how tools once available only to big companies with big budgets are now becoming accessible to almost anyone.Roger is also the author of Friction, named a Top 3 Management Book by PwC’s strategy+business, and Brainfluence, which has been published in 11 languages.

He brings an unusually practical perspective to the subject. Roger co-founded College Confidential  and today he combines that entrepreneurial experience with behavioural science in his writing, speaking and teaching.He is a lecturer at McCombs Business School, a Forbes contributor and host of the Brainfluence podcast — and his work focuses on helping organisations understand people better, remove unnecessary friction and communicate in ways that actually work.

What’s the last thing you learned simply because you wanted to know?

Episode summary
Why do we feel the need to justify what we learn? My guest on this episode is Annie Wagstaff, a musician and composer whose career has taken her around the world touring with Take That and into writing music for advertising. But alongside her work in music, Annie has developed another passion: learning about whatever happens to make her curious.That could be vine tomatoes, animals, colour, knots, the human body, or simply something she notices while walking through a supermarket.

Annie shares what she discovers on social media, not because the knowledge necessarily has an obvious purpose, but because she finds it interesting. And that raises a fascinating question: what happens to the natural curiosity we have as children as we become adults?In our conversation, we explore creativity and constraints, sonic branding, why children pick up stones while adults tell them to put them down, the pleasure of knowing a little about a lot, short attention spans and hyperfocus, authenticity in an age of AI, and why learning something without knowing what you’re going to do with it might be exactly the point.We also talk about Take That, vine tomatoes, staring at flowers, doomscrolling, notebooks, knots and sailing — the kind of eclectic mix that an episode about curiosity really ought to contain.

Guest bio
Annie Wagstaff is a London-based guitarist, musician and composer.She has worked as a session musician, toured internationally with Take That, and composes music for advertising and other commercial projects.

Earlier in her career, Annie also released her own music and built a large following online through her guitar playing.More recently, she has used her social channels to share the things she learns simply because they interest her — turning subjects ranging from science and animals to everyday observations into short, accessible explorations of curiosity.

What happens when someone who spends his life thinking about risk, decision-making and human behaviour is confronted with an uncertainty he simply can’t control?

Episode summary
My guest is Paul Craven, a behavioural scientist, former investment professional, magician and keynote speaker, and one of my favourite people to talk to. When we sat down to record this episode, I noticed that Paul’s voice sounded different.

His explanation — that he had recently been diagnosed with oral cancer — took our conversation in an unexpected and deeply personal direction.We explore what his experience has taught him about uncertainty, why he deliberately chose not to Google his diagnosis, and the difference between having information and having useful information.

From there, we explore luck and skill, decision and gratitude journals, relationships versus transactions, the dangers of binary thinking, and why sometimes the best thing you can do when you’re in a bad mood is go for a walk in the rain. It’s a conversation about behavioural science, but also about perspective, paying attention and what we discover about ourselves when life doesn’t go according to plan.

Key themes
Living with uncertainty and the psychological value of having a plan
Why more information isn’t always better information
AI, search engines and our desire for certainty
Nuance versus binary thinking
Luck, skill and decision journals
Gratitude and paying attention to what matters
Relationships versus transactions
Storytelling, lived experience and different ways of seeing the world
Chameleon Thinking and the value of changing perspective
Guest Profile - Paul Craven

Why do we rate everything and why do we do so on a scale of one to five stars? What happens when systems designed to help us make better choices start influencing our behaviour in ways we don’t necessarily notice?

Episode Summary
My guest is Benji Wilson, a journalist, TV critic and author of Rate This Book. Benji’s day job involves rating other people’s work, but when his children pointed out that Rotten Tomatoes was also rating him, it prompted him to investigate the ratings culture that surrounds us. In our conversation, we explore where ratings came from, why the five-star system became dominant and the psychology that makes us pay attention to the opinions of people we’ve never met.

We discuss social proof and the wisdom of crowds, why we often use ratings to avoid making bad decisions rather than to identify the very best option, and what happens when reviews are fake, manipulated or simply unfair.

We also explore the consequences of moving from rating products and services to rating people, including Uber drivers, hospitality workers and doctors, and why a single negative review can have significant consequences.Benji also explains how ratings might have applications in places we wouldn’t necessarily expect, including workplace appraisals and even democracy, where alternative voting systems use ratings to allow people to express more nuanced preferences.

And, appropriately for someone who has written a book called Rate This Book, we discuss what it feels like when the ratings are turned back on you — including why an anonymous three-star review might actually be more useful than a perfect five-star score.

Guest Profile
Benji is a journalist, author and TV critic. His book, Rate This Book, explores how ratings and reviews came to dominate modern life, the psychology that makes them work and what happens when the systems designed to help us make choices begin shaping those choices themselves.
