17. The Diderot Effect
33:56||Season 5, Ep. 17Are you a slave to your possessions?Do your possessions form part of your identity?How easy is it to fall into a trap where one new purchase begets another, and another, and another...?We explore the Diderot Effect - so called after an essay written in 1769 by French philosopher, writer, and art critic who served as one of the most influential figures of the Age of Enlightenment. "Regrets On Parting With My Old Dressing Gown" details how receiving a luxurious scarlet robe as a gift made his existing belongings look shabby, sparking an out-of-control spending spiral to replace all his old furniture to match the new garment. In the episode Jono references that he first heard about it from James Clear who went on to include it in his highly successful book, Atomic Habits.Episode Summary00:00 Summer Break Notice00:51 What Is the Diderot Effect04:09 Diderot and the Dressing Gown06:05 When Stuff Owns You09:47 Our Diderot Moments13:45 Tools Cars and Tech Spirals20:23 Business Growth and Office Upgrades28:00 How to Master the Effect31:18 Final Quotes and Wrap Up

16. Why Only 2 Countries Are Double-Landlocked
31:00||Season 5, Ep. 16In a double-landlocked country you must cross at least two national borders to reach a coastline connected to the world’s oceans.In this episode we talk about the nuances of landlocked definitions (including why the Caspian Sea doesn’t count) and identify the only two double-landlocked countries: Liechtenstein, surrounded by Switzerland and Austria, and Uzbekistan, surrounded by landlocked “stans.”We talk about why ports and sea access matter for trade and geopolitics. We also explore the ideas and definitions for landlocked US states (including Nebraska as “triple landlocked”), the furthest points from the sea, disputed borders, recursive islands, and a Google Maps oddity between the Shetlands and Faroe Islands. It's definitely one for maps and geography nerds!References: Tom mentions Tim Marshall's book, Prisoners of GeographyJono also references some of his other sketches: Recursive Islands and Triple Landlocked StatesWe also reference the previous podcast episode on Antipodes for how so much of the Earth is water.Episode Summary:00:00 What Double Landlocked Means04:17 The Only Two Countries05:45 Caspian Sea and Definitions06:53 Recursive Borders in UAE08:33 Why Ports Matter12:13 Bolivia and Africa Surprise13:52 Distance From the Sea18:02 Landlocked US States Debate25:23 More Geography Oddities28:48 Shetlands to Faroes Map Quirk30:06 Closing Thoughts
15. How To Become An Overnight Success.
35:20||Season 5, Ep. 15This discussion centres on “overnight success” as an illusion; prompted by Jono’s sketch of Twitter Cofounder, Biz Stone’s quote: “Timing, perseverance, and 10 years of trying will eventually make you seem like an overnight success.”Using an iceberg metaphor (most work hidden below the surface), we explore how Twitter, Uber, Airbnb, GoPro, Pinterest and other “sudden” hits were built through long periods of effort, failed attempts, near-bankruptcies and luck-driven timing.Tom shares his own journey from inventing the curved nail file in 2004 to major success after winning The Apprentice, plus later product launches, illustrating visible turning points built on years of groundwork. We also look at creative fields and sport, survivorship bias, and belief, persistence, readiness, and timing.External LinksIn the conversation, we referenced these items which you can find more information on here:Our Listener SurveyBiz Stone's book: Things A little Bird Told MeJono's sketches on Iceberg Orientation & Survivorship BiasOur previous episode on Optimism BiasEpisode Summary00:00 Introduction01:13 Biz Stone Quote03:10 Iceberg Metaphor04:09 Biz Stone Backstory04:36 From Blogger to Twitter07:37 Myth of Viral Success09:59 Tom's Real World Examples12:31 Sketchplanations Slow Burn16:06 Perseverance and Belief18:52 Timing and Viral Moments20:59 The Turning Point21:35 Apprentice Timing Advantage24:43 Jono on Luck and Timing26:34 Sports Overnight Success28:42 Survivorship Bias Reality29:47 Do Overnight Successes Exist32:15 Advice Perseverance Mindset34:29 Wrap Up and Credits
14. Play Until Something Gets Broken
22:30||Season 5, Ep. 14In this fun and nostalgic conversation, we discuss Jono's observation that with indoor games especially, as the momentum builds, you keep playing until something gets broken!There's a cheeky inevitability to it. It's a situation we've almost all certainly been in - whether you were the protagonist or not!We share our childhood and adult stories of hallway ball games, broken lamps and mirrors, a university corridor culture of improvised sports, Nerf-gun firing ranges ending with a foam dart to the eye, and a school-trip pillow fight that took out a light fitting. The conversation expands to similar “stop conditions” in outdoor games and with sports injuries, and connects the idea to the Generalised Peter Principle: anything that works is pushed into progressively more challenging situations until it fails. What are you experiences with this?Links to items we discussed:Jono's impossible "lamp thru TV" sketch has connotations of Escher's Impossible StaircaseJono's sketch and our past podcast episode about The Peter PrincipleJono's sketch on The Generalised Peter PrincipleRob referenced a visit to the Belleek Pottery factory whilst filming in Northern Ireland.Episode Summary:00:00 Podcast popularity in USA01:12 The Indoor Games Rule02:48 Ball Games Banned04:40 Injuries End The Game08:09 Uni Corridor Games08:58 Sketch Breakdown10:37 Why Indoor Play Matters11:00 Messy Space Dreams14:02 Adult Injuries End Games14:58 Pillow Fight Lamp Smash16:05 Hide Underwater Tactic16:40 Generalized Peter Principle17:32 Sacrificial Breakables21:11 Anger Smashing Question21:44 Closing
13. Submarine Lessons for Business Leadership
52:10||Season 5, Ep. 13US Navy submarine captain and author David Marquet discusses leadership lessons from turning the USS Santa Fe from worst to best, focusing on “pushing authority to information” rather than pushing information up a hierarchy. Marquet critiques industrial-age leadership language that seeks obedience and creates “bobblehead” agreement, arguing that real engagement comes from giving people decision-making authority,He also explains “distancing,” as a leadership and decision-making tool: viewing oneself from a third-person, from a different time, and/or from a different place to reduce ego and defensiveness over previous decisions. A thoroughly fascinating chat with a very talented and fun individual. External Links for items referenced in the conversation:David’s 3 books can be found here: Turn the Ship Around (+ workbook), Leadership is Language, and DistancingHere are two of many of David's talks to be found on YouTube: What is leadership? and Turn the Ship Around at the World Web ForumHere's the YouTube video of David rating submarine movies for how realistic they portray life under the waves.David talks about advice given to him by Simon SinekSome of Jono's other skecthes references in this podcast include: Solvitor Ambulando (it is solved by walking); 9 windows (problem solving tool); Anchors and Tugboats (self-talk)David talks about ultra-runner extraordinaire Courtney DauwalterSummary00:00 From Cold War Kid to Submariner03:02 Life Aboard a High-Performing Sub03:53 The Arbitrary Officer Divide04:40 Student Not "Expert"05:51 Words That Kill Curiosity08:44 What Leadership Was Taught12:37 Pushing Authority to Information16:03 Submarine Leave Approval Hack20:02 Authority in Everyday Workplaces21:59 Bias for Action and Excellence22:46 Distancing to Decide Better25:41 Put Them In Your Chair26:12 Distancing In Space & Time27:45 Inviting Feedback Culture28:52 Nine Windows Thinking Tool30:25 You Can Do It Self Talk32:28 Regret Proof Decisions38:04 Journaling Into A Book39:41 Be Your Own Coach45:50 Team Reviews Without Defensiveness47:19 Live Big Bold Lives48:14 Submarine Movies And Ambiguity50:55 Wrap Up
12. Hitting the Target: Accuracy vs. Precision
29:44||Season 5, Ep. 12Using Jono’s sketch of four archery targets, we discuss why and how accuracy and precision differ.Using many different examples, we frame the distinction as “accuracy being true to intention and precision being true to itself,” also phrased as doing the right thing versus doing it right.The sketch is inspired by Simon Winchester's book, Exactly, where precision and accuracy are connected to the industrial revolution via Henry Maudsley’s innovative screw-cutting lathe, micrometer, and the concept of interchangeable parts. The conversation broadens to explore examples in food (McDonald’s vs artisan meals), recipes, recruiting, IQ tests (validity vs reliability), indoctrinated beliefs, gut feelings, culture’s return to individual craftsmanship, AI’s variable answers, LED mask wavelength tolerances, and targeting weapons.External linksAlso referenced in this episode:Jono's sketch that describes the difference between Reliability and Validity.Jono's sketch inspired by Roger Martin's Knowledge Funnel.Jono's sketch outlining The Beard Cycle.Episode Outline00:00 Accuracy vs Precision: the Four Target Sketch03:23 True to Intention04:11 Ball Through Window05:44 Precision Built World09:45 Food and Recipes13:27 Calibration and Scales14:47 Manufacturing Tolerances16:51 Hiring and Testing19:16 Beliefs and Education23:01 Culture and Craft26:09 Doctors Robots and AI29:03 Wrap Up and CreditsAll music on this podcast series is provided by the very talented Franc Cinelli and you can find more tracks at franccinelli.com
11. Do you Know Your Dashes?
33:19||Season 5, Ep. 11If you like the finer details of grammar and punctuation, then you're gonna love this episode.We geek out on the subtle, but incredibly important and occasionally crucial differences between three little horizontal lines: the hyphen - the En Dash – and the Em Dash —Jono explains hyphens for line breaks and compound terms, how usage can evolve into single words (e.g., wildlife, wellbeing), and why hyphen placement can change meaning (e.g., five-dollar bills). The en dash is described as linking ranges and relationships (pages, dates, times, scores, routes, debates, partnerships, negotiations), with notes on how to type it. The em dash is framed as a stronger-than-comma interruption for added thoughts, with style cautions and typing methods. They discuss underscore origins from typewriters, punctuation differences across countries, and how AI popularized em dashes as a telltale sign of machine-written text.Most importantly though, we discuss why this matters and that if used correctly, they can help avoid misunderstandings.Episode Summary00:00 Welcome to Sketchplanations00:40 What Are Dashes03:09 Hyphen Basics04:32 Hyphenated Words05:35 Language Evolves07:00 Hyphen Pitfalls07:31 Tom on Hyphens10:38 Meet the En Dash11:41 Typing En Dashes12:32 En Dash Use Cases14:47 Spacing and Style15:30 Introducing Em Dash15:33 Em Dash Basics16:15 Style Guide Rules18:08 Brackets vs Speech18:57 Where Names Come From20:32 Underscore Origins22:05 Reading Dashes Aloud24:39 Does It Matter26:04 Oxford Comma Stakes28:36 AI Em Dash Tell29:59 Typing Em Dashes30:32 Punctuation By Country31:41 Morse Code And Minus32:43 Final Sign OffExternal LinkThere's only one link this week:Jono referenced the book Strunk and White : The Elements of StyleAll music on this podcast is provided by the very talented Franc Cinelli.
