Key Discussion Points & Insights
1. 15 Years of 99% Invisible
- Roman reflects on the show’s growth and its original release in September 2010.
- Listener stories, feedback, and curiosity have shaped the show and helped it expand its definition of design.
“Fifteen years of you, our listeners, sending us the most incredible observations about the built environment that we never would have noticed on our own.” — Roman Mars [01:10]
2. How to Make a City 10% Better—Without Spending Money
[03:02]
- Question from Taylor (New Jersey): You can only rearrange, remove, or repurpose existing resources.
- Roman’s answer: Dedicated rapid bus lanes using existing buses.
“Take every bus…school buses, public transit buses, and just have a lane, have them run every 10 minutes between places that are important. You will make a city tremendously better.” — Roman [03:34] - Acknowledges that true zero-budget fixes are rare and meaningful improvements typically require investment.
3. Defining “Design”—How the Show’s Perspective Has Changed
[05:09]
- Taya (Seattle): Has Roman’s definition of design changed?
- Roman: Initially focused on buildings, cities, products, and visual design, but always intended for a broad definition.
“I always thought of it (design) pretty broadly. It has gotten more broad over time... as the show opened up and had more people in it and more brains on, it has evolved because of their interests.” — Roman [05:37] - Staff diversity and interests have further expanded the show’s definition.
4. Designs Worth Another Chance: The Case for Cash
[07:11]
- Asked to pick a designed object (other than the funicular) that deserves a revival, Roman chooses cash.
- He worries about social and economic exclusion in a cashless society and the loss of both practicality and artistry of paper currency. “I think there’s something that we will lose… there’s a societal cost at risk when we lose cash completely.” — Roman [07:44]
5. Untold Story: The Brannock Device
[10:00]
- Roman admits fascination with the Brannock device (the metal tool for measuring feet in shoe stores). “They've made one thing. And that is that thing. They've made that metal thing in different colors... I'm just kind of fascinated by it.” — Roman [10:19]
- Finds beauty in its elegant, simple design and singular company focus.
6. 99PI's Letterboxd “Top 4 Movies”
[12:23]
- Prompted to pick four movies that define 99% Invisible’s taste or vibe.
- Jaws — For its multi-genre brilliance and layered storytelling.
- The Godfather — A classic with depth and intrigue.
- Fargo (Coen Brothers) — For its tonal balance of humor, horror, and human nature.
- Perfect Days (Wim Wenders) — Most “99PI” movie; about a man cleaning Tokyo’s public toilets, with a focus on ritual, care, and the unnoticed beauty of everyday life. “If everyone watched it, the world would be a better place. Like, it really teaches you about contentment.” — Roman on Perfect Days [15:31]
7. Changing the U.S. Constitution — Eliminate the Electoral College
[17:17]
- Producer Joe Rosenberg asks: What’s one constitutional change you'd make?
- Roman: Abolish the electoral college for direct presidential election.
“I’d much rather have the tyranny of the majority than the tyranny of the minority.” — Roman [17:40]
8. Design-Related Hill to Die On: Anti-Efficiency
[18:14]
- Roman rails against the relentless pursuit of efficiency for its ability to destroy good things—journalism, pop culture, city life. “The idea that you're trying to get things to be as efficient as possible is actually a terrible, world-destroying idea…” — Roman [19:02]
- Praises the creative potential and social good in inefficiency.
9. Roman’s Memphis Odd Jobs
[21:40]
- Gelsey Bennett: Was Roman a Papa John’s delivery guy in Memphis?
- Yes—Roman details delivering pizzas for his cousin’s Papa John’s locations and working at a Germantown video store and a grocery.
10. The 99PI Episode Production Process
[24:13]
- From pitch to air, an episode can take about 16 weeks.
- Steps: Pitch, reporting/interviews, script, “read to tape” (table read), group notes (“Can We Get Here Faster?” and “Relentlessly Chronological” are common script critiques), audio draft (“listen edit”), further group feedback, final mix. “Every story has been touched by… at least five or six people. Like, it really takes a lot.” — Roman [29:38]
- Vivian likens the process to turning a story into “soup” and then a “butterfly.”
11. Ultimate 99PI Merch: A Dieter Rams-Designed Podcast Player
[34:16]
- Editor Kelly Prime asks for dream merch.
- Roman’s pick: A minimalist, Rams-esque dedicated podcast player. “A dedicated podcast player… maybe a little bit of a screen on it… but yeah, I think something like that.” — Roman [36:02]
12. What Would “1% Visible” Be?
[36:32]
- Guest Gillian Jacobs: What if 99PI focused on the visible 1%?
- Roman sees a possible show explaining tactile or infrastructural things (“how stuff works”), focusing less on stories and more on the direct, physical function of everyday systems.
13. Object to Explain Humanity to Aliens
[37:35]
- Roman’s pick: The Golden Gate Bridge. “It looks like what it does. Its design and physics and stuff is on display, and it’s beautiful.” — Roman [37:44]
14. Most Emotionally Manipulative Design Element
[38:13]
- Faces and eyes—on tip jars, delivery robots, pets.
- Also: Music in storytelling and movies. “Anything that has eyes or looks like somebody’s watching you is probably the most emotionally manipulative stuff you encounter on a daily basis.” — Roman [39:54]
15. Biggest Change in Thinking About Storytelling or Design
[40:24]
- Roman initially believed great content had to be brief (five-minute polished stories). Now embraces longer, more conversational formats—even “three hours of two dudes talking about fuck.”
“I just sort of forgave myself and gave myself the permission to create one on my own.” — Roman [41:27]
16. Blame for Flag Redesign Mania (Bonus)
[42:07]
- Vivian asks if Roman feels responsible for flag redesign trends after his viral 2015 TED talk.
- Roman admits he (and the show) influenced hundreds of city flag redesigns. He cautions against design orthodoxy, encouraging meaningful differences.
“Occasionally… people create a lot of Chicago-style flags instead of something kinda cool and on their own… The key is: Love your flag. Use your flag. Like, it's a resource that's wasted if not.” — Roman [47:16]
17. The Twins: From Tiny Letter Ads to College (Bonus)
[49:11]
- Listener Tina asks about Roman’s twins and their feelings about being part of the show.
- Roman: They’re heading to college, are proud of their early cameos, and understand their role in the show's early financial foundation. “This empire was built on the charm of those twins.” — Roman [49:48]
- Maslow and Carver (the twins) appear at the very end, sharing their plans and gratitude.
Notable Quotes & Memorable Moments
-
On the show’s arc:
“This year marks the 15th anniversary of 99% Invisible, which is honestly kind of hard to believe… If 99% Invisible were a person, it would be old enough to have a provisional driver’s license in some states.” — Roman [01:10] -
On design and inclusion:
“The openness of cash as a system is super important and it'll be a shame if it goes away completely.” — Roman [09:03] -
On the “rigorous but gentle” editing culture:
“I take real pride in that… Like most people who've done a tour through the show have comment[ed] that when they do this in other places, it's not so fun.” — Vivian [30:02] -
On emotionally manipulative design:
“If your kids weren’t cute, if your dog wasn’t cute… you would never endure them in other ways if they didn’t have these just cute little faces.” — Roman [39:54] -

“It is funny that the lesson that you learned after 15 years of making a podcast is that you like podcasts. Exactly.” — Vivian and Roman [41:36] -
