In high school, a friend and I produced a 10min VHS exploring Joseph Campbell’s monomyth. It was the jankiest, most cringeworthy video ever (we wrote the credits on the fridge in mustard). Fascinating to think that type of content might return as an honest signal of effort given these tools.

This will never not be an amazing office.

While I can't wait to read this new collection, I'm still recovering from @kyliu99.bsky.social's "State Change" so it may take some time

Cool new research on 167 U.S. cities: Uber and Lyft entry raised regional GDP per capita by ~2.9% and boosted unstable/gig-style employment by ~3.7%. Effects on total jobs and total earnings? Statistically indistinguishable from zero.

Study finds women employees more likely to build friendships through existing connections, creating larger networks. Men developed selective friendships. Female friendship networks contribute more to org stability; male friendships more focused on individual benefit. phys.org/news/2026-08...

On our way back from a faculty event. Do we caulk the wagons and float?

Ha, checkmate, I got imposter syndrome. (Also turducken, triathlete, skanky, and immersion blender)

Throwback to the most intense classroom I've ever presented in; seen here *from the street level windows* that allow passersby to watch the presenter beset from all sides in the middle of the ring @Bocconi

This is fantastic, and a key issue in #mgmt and #orgstudies as well. With enough variables we can lead our models to any output, so more moving parts frequently leads to less insight (as we wrote about here: sms.onlinelibrary.wiley.com/doi/abs/10.1...)

This is a well done reflection. Business models and investment both have gravity; in this case, the gravity of the investment they’ve taken works against the gravity of their business model

Very cool analysis of the Maine 70.3 Half Ironman men’s finishing times last weekend (assembled by a friend). Note that the pool of competitors in each age bracket gets smaller as ages go up, but the finishing times really don’t change much!

If you’re in Philly early for #AOM2026 and looking for something to go, I highly recommend touring the US Mint. Great exhibit design, see the machines in action, quick visit. www.usmint.gov/about/tours-...

Seems like a good time to remind folks that even if you are safe from fires, breathing smoke is, like, really bad. A DIY air filter can help. #wildfire #pacificpalisades #crbox

Oh my gosh, I love everything about this: the concept, the community, the Risky Business homage www.news-gazette.com/business/ent... h/t @ecourtem.bsky.social

New paper alert! Learning to grow in entrepreneurial ecosystems. entrepreneurs learn about entrepreneurship from other entrepreneurs. Not from accelerators, not from textbooks, not from their very handsome entrepreneurship professors — from each other. 🧵 1/7 link.springer.com/article/10.1...

"writing code to solve a problem" used to have "understanding the problem" as a prerequisite. but vibecoding allows solution-shaped objects to be produced without any of the hard-won understanding. beware of solution-shaped objects.

ok, yeah, in retrospect not an ideal bookmark to be using, in the courthouse, while waiting in the jury pool

“Some things need to become enormous to survive. Other things survive because they never needed to become enormous.”

Wonderful piece by Donna Harris on pitch competitions in entrepreneurship: They reward the wrong things, but we just can't quit them (h/t to @vanishingcorp.bsky.social) buildersfieldguide.substack.com/p/breeding-c...

I think it's under-appreciated how much user-hostile recipe sites and news articles smothered in pop-ups and video ads have negatively polarized the average normie against the open web, and helped to drive adoption of AI as an alternative way to get basic information

re-upping this in light of the very amusing Granta fiasco

I've never liked the phrase "kill your babies" as a piece of writing advice, but oooof, it sure does hurt to watch paragraphs that took days to craft end up on the cutting room floor

Sure the world is in tatters and gas is $75/gallon but I just bought four Brother ink cartridges for $25, for a 10 year old printer that's still going strong?

Sharing a good friend's Kickstarter. Erin is a designer and illustrator; her book Girl Math is gorgeous and offers accessible advice to folks (esp. young women) who weren't taught about or feel overwhelmed by personal finances. www.kickstarter.com/projects/eri...

A female experimenter, appearing pregnant, boarded the train with an observer. In the experimental condition, an additional experimenter dressed as Batman entered from another door. Passengers were significantly more likely to offer their seat when Batman was present (67.21% vs. 37.66%).

My mother spent much of her career as a florist, which made Mother’s Day a mixed bag for her (looong days and too much work). So this year when my 6yo and I made paper flowers with the tagline, “no florists were harmed in the making of this arrangement” 😜

A gorgeous, quiet grey day in @giesbusiness.bsky.social during oops-no-finals week. #illini

Rereading Edward Abbey’s “Down the River” to prep for a float trip at the end of the month, and delighted to find a perfect start to the preface: “For me, this floating began near home…my brother Hoots and I built a boat. To be honest, we didn’t build it, we stole it. Nor was it exactly a boat.”

"That's kind of a wild thing," said one man at South Station. "I think the researchers might be a little bored over at UCLA."

One underappreciated value of coding your own interviews from transcripts by hand is the self-coaching potential it brings. It can be annoying & challenging, but really lays bare the potential bad habits & mistakes that you still make, no matter the level of experince. We all have our blindspots.

Big day today if anybody wants to pitch me an irresponsible investment or adventure

Studies involving venture capital, pro sports, healthcare & entertainment find all-women groups face a collaboration penalty that solo women & all-men groups escape. All women groups seen as more threatening & more likely to challenge power structures. theconversation.com/why-women-in...

Very odd to see Claude’s writing ticks show up in a print copy of the Economist (ironically, in an article about AI 🙄)

Turns out Indianapolis airport is ORD’s mirror twin. Connecting through O’Hare is like being a salmon going over a hydro dam; this is a meditation spa in comparison 🤣

Millennial hustle culture

Thinking more about the Yale report. Parts of it are thoughtful. But Yale wants to make what is essentially a structural problem a question of behavioral one.

Fantastic panel on the role of agentic AI in research, hosted by @strategicmgmt.bsky.social and Sukhun Kang, with @mattbeane.bsky.social, Gwendolyn Lee, @cgartenberg99.bsky.social, @joshgans.bsky.social. Image from Claudine Gartenberg. It's a new world (with lots of unanswered questions).

Hummingbirds shouldn't be allowed to migrate this way. They're too small. It's too far.

Also bear in mind that ‘entrepreneurship and small businesses’ also includes artists, designers, musicians, writers, and other independent creative folks — this is a huge, systemic *cultural* loss as well as an economic loss.

“False certainty is dangerous; it rules out all possibilities but one and in essence surrenders to that imagined future.”
