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!

Median times are fairly consistent in the 18-44 range, with some of the older competitors displaying faster times than much younger athletes A stacked distribution plot of mens finishing times at the Maine 70.3 half Ironman.

The most surprising finding: despite facing the same dilemmas, educators mostly navigated them independently, with little coordination or guidance from peers. The result? A huge diversity of course designs — with almost no clustering into distinct "types."
A correlation table showing 24 coded variables across the courses; e.g., type of university, instructor demographics, course topic focus, use of templates, etc. Correlations are very low across the board, showing little consolidation in terms of approach across courses studied.

Rather than just picking a side, educators drew from a repertoire of creative strategies: leveraging their local ecosystems, dual-purposing assignments to serve multiple goals at once, and using templates/frameworks to stretch limited class time.

The middle rows of the table illustrate example tactics in the data - i.e., how each strategy manifests in the courses studied. The bottom rows of the table detail observed consequences at the student, educator, and field level.

💯 agree. Pfeffer et al (2005) are arguing explicitly for the treatment effect, through socialization. I'm out of my expertise here, but my understanding is that the evidence is mixed. Gerlach (2017) for example calls for more (and better) research to disentangle. pmc.ncbi.nlm.nih.gov/articles/PMC...
Text from the paper being discussed, by Ferraro et al (2005). It reads, "he behavioral assumptions and language that characterize economics influence theories and expectations about human behavior. These widely espoused and accepted theories, and the language they embody, then influence how people behave individually and the institutions they design as contexts for others’ behavior. Individual behavior and institutional designs create a reality that, in turn, reinforces beliefs in the validity of assumptions of economic theories."Text from the paper being discussed, by Ferraro et al (2005). It reads, "We would expect to find different results in countries where the dominant version of economics is not imbued in the principles of the neoclassic orthodoxy. The experiments of Frank et al. (1993) provide some suggestive evidence. They compared the effect of two different types of economics classes: a class in microeconomics taught by a neoclassical economist and one taught by an institutional economist. The students in the institutional economist’s class did not exhibit the same increase in self-interested behavior found in the neoclassical economist’s class."

FWIW, I think business schools are in trouble if the world (and our prospective students) believe that our product makes them bad people. First image is from Fabrizio, Pfeffer, and Sutton (2005). journals.aom.org/doi/10.5465/...
Text from a paper by Ferraro, Pfeffer, and Sutton, titled, "Economics language and assumptions." The text reads, "Cadsby and Maynes (1998)found that economics and business students, compared to nurses, tended to move toward an inefficient free-riding equilibrium in an experiment using a threshold game. In an ultimatum game (e.g., Thaler, 1988), Carter and Irons (1991) found that student subjects who were economics majors tended to keep more of the resources for themselves than students who had declared a noneconomics major and were not enrolled in an economics course. Frank, Gilovich, and Regan (1993) found that economists defected more often in a prisoner's dilemma game and that economics professors were less likely than those from other disciplines to donate to charity. Frank and Schulze (2000) found that economists were more corruptible than others. In their experiment, students in a German university were asked to recommend a plumber for a film club from a set of offers that varied both by the price charged and by the amount the person would receive if the plumber they recommended was selected. Economics students were more likely to recommend a plumber that charged a higher price when they received more money for doing so. There is, then, a large and growing body of literature that suggests that economists and economics students act differently from others. Why?"Text from the economist article being discussed. The text reads: "The stereotype of profit-maximisation is not entirely unfounded. One study by Daron Acemoglu, Alex Xi He and Daniel le Maire, three academics, shows that managers with business degrees are less likely to share profits with workers than their less commercially experienced peers. What are these folks like on weekends? Another paper from 2007 by Nicole Stephens, Hazel Markus and Sarah Townsend found that when compared with firefighters, MBA students were orders of magnitude more likely to be upset if a friend knowingly bought the same car as theirs."

I disagree (podcasts can be great), but this IS a chance to share one of my favorite quotes on writing
A photograph of a quote by Michael Eric Dawson, from an article called “the ghost of Corn West”. The quote reads “The ecstasies of the spoken word, when scholarship is at stake, leave the deep reader and the long listener hungry for more. Writing is an often-painful task that can feel like the death of one’s past. Equally discomfiting is seeing one’s present commitments to truths crumble once one begins to tap away at the keyboard or scar the page with ink. Writing demands a different sort of apprenticeship to ideas than does speaking. It beckons one to revisit over an extended, or at least delayed, period the same material and to revise what one thinks. Revision is reading again and again what one writes so that one can think again and again about what one wants to say and in turn determine if better and deeper things can be said.”

Part of what makes ventures effective in crisis contexts is that they tend to be informal and flexible – which works well when the context is ambiguous and dynamic For ex, entrepreneurs set up money transfer systems and a centralized support wiki after Hurricane Katrina Link: bit.ly/40w5oAl
A screenshot of an article titled "Coordinating expertise among emergent groups responding to disaster", by Ann Majchrzak, Sirkka Jarvenpaa, and Andrea HollingsheadA screenshot from Wikipedia of an article about the Katrina PeopleFinder Project. The first paragraph reads,

"The Katrina PeopleFinder Project was set up in early September, 2005 in response to the dozens of groups collecting "lost and safe" lists for people affected by Hurricane Katrina.[1] It provided a virtual messaging center using skype as well as creating "a uniform standard for collecting, compiling, data-entering", and "searching information on people affected by Hurricane Katrina".[2]

The project was conceived on Friday, September 2 with the establishment of the KatrinaHelp Wiki. Volunteers manually entered 15,200 records in less than 24 hours[2] and data entry was stopped with over 90,000 entries (when no new entries were apparent) by Tuesday, September 7. Dozens of technologists and thousands of volunteers had helped make it happen.

The Katrina PeopleFinder Project is an example of a nonprofit technology initiative implemented entirely by volunteers. Over 4000 people donated their time as data entry crew members."

We often think of outside agencies or carpetbagging outsiders swooping in, but research suggests that entrepreneurs are often members of the local community – folks who know the lay of the land, who needs help, and how to get things done. Paper link: onlinelibrary.wiley.com/doi/abs/10.1...
A screenshot of the article "Local venturing as compassion organizing in the aftermath of a natural disaster: The role of localness and community in reducing suffering" by Dean Shepherd and Trenton Williams. 

The abstract reads, "In contrast to models of compassion within existing organizations, this grounded theory study examines how ventures emerge relying on localness and community in direct response to ‘opportunities’ to alleviate suffering in the aftermath of a natural disaster. While a natural disaster is a surprising disruptive event devastating a local community, that local community is nested within a broader community, which can be a source of abundant resources. Ventures created in the aftermath of a natural disaster, given local knowledge and unencumbered by pre-existing systems, procedures, and capabilities, are highly effective at connecting the broader community with the local community through customizing resources to meet victims’ needs and to quickly delivering these resources to alleviate suffering."

Very cool new paper by Jiayi Bao at @tamu.bsky.social: #Makerspaces lead to more startups. This is driven by intentional (vs accidental) hardware founders - i.e., its not about ppl playing & discovering ideas, but by deliberate experimentation & prototyping! onlinelibrary.wiley.com/doi/full/10....
Screenshot of the paper, from Strategic Management Journal, titled "Do makerspaces affect entrepreneurship? If so, who, how, and when?" The abstract reads: Makerspaces are physical spaces that offer individuals fabrication tools and materials (e.g., 3D printers) to make artifacts. Although not designed specifically for entrepreneurs, these spaces offer affordable access to rapid prototyping infrastructure. This study examines whether makerspaces affect entrepreneurship and, if so, who, how, and when. Leveraging hand-collected data on US makerspaces and large archival data on Kickstarter projects, I show that makerspaces positively affect entrepreneurial participation and subsequent commercialization outcomes. However, these effects are mostly specific to hardware
(vs. nonhardware) activities that typically involve physical prototypes. I find that the effect on entry is driven more by new (vs. established) but intentional (vs. accidental) entrepreneurs and that the effect on
commercialization comes from two operating and complementary channels—resource provision and social facilitation.A map of the United States by metropolitan statistical area (MSAs), showing the density of maker spaces. There are a lot!

If you can't give up entirely on HBS, you can also offer students a choice. For my MBAs, I create two course packs: A “full” coursepack, containing all the readings ($$, but easy), and a “lite” version that contains only those readings they can’t get for free somewhere.

A text-heavy image describing how I designed a syllabus using only free (to students) materials. I relied largely on book chapters, HBR articles, research articles, and video content.
