Brandon DonnellyCanada must become a global superpower
The silver lining to the US starting a trade war with Canada and regularly threatening annexation is that it has forced this country out of complacency. Indeed, I'm hard pressed to remember a time, at least in my lifetime, when patriotism and nationalism has united so much of Canada. According to a recent survey by Angus Reid, the percentage of Canadians expressing a "deep emotional attachment" to the country jumped from 49% in December 2024 to 59% in February 2025. And as further evidence of...
Brandon DonnellyThe bank robbery capital of the world
Between 1985 and 1995, Los Angeles' retail bank branches were robbed some 17,106 times. In 1992, which was the the city's worst year for robberies, the number was 2,641. This roughly translated into about one bank robbery every 45 minutes of each banking day. All of this, according to this CrimeReads piece by Peter Houlahan, gave Los Angeles the dubious title of "The Bank Robbery Capital of the World" during this time period. So what caused this? Well according to Peter it was facil...
Brandon DonnellyThe story behind those pixelated video game mosaics in Paris
If you've ever been to Paris, you've probably noticed the small pixelated art pieces that are scattered all around the city on buildings and various other hard surfaces. Or maybe you haven't seen or noticed them in Paris, but you've seen similarly pixelated mosaics in one of the other 79 cities around the world where they can be found. Or maybe you have no idea what I'm talking about right now. Huh? Here's an example from Bolivia (click here if you can't see...

This morning I came across the below graph in a Medium article by Eric Jaffe of Sidewalk Labs. It is taken from a research paper by Elisabeth Ruth Perlman called, Dense Enough To Be Brilliant: Patents, Urbanization, and Transportation in Nineteenth Century America.
What this chart shows is patents issued – a proxy for innovation – in all U.S. counties between 1790 and 1900. This data is then compared against access to transport, such as rail. The discovery is a statistically significant relationship between innovation (patents issued) and rail (transport) access.
The spike in the 1850s (shown above) is as a result of increased rail access.
But Perlman takes it a step further and asks: what is causing this spike in innovation? Is it because inventors and creators started responding to the larger market now accessible to them because of rail connectivity? Or did transportation somehow improve productivity and the flow of information?
To answer this question, she dug into the patents themselves (over 700,000 of them) to try and identify how ideas and key words were spreading. What she found is that rail access alone doesn’t encourage innovation. References to new technologies did not increase.
What mattered was what happened locally. Transportation improvements promoted urbanization and density during her study period, and that’s what drove innovation. Connectivity created agglomeration economies at the local level.
Obviously a lot has changed since the 19th century. But whether it’s rail connectivity or internet connectivity, have the rules really changed? Place still matters. What happens locally still matters. Perhaps even more.
This is an important lesson to consider as we build our cities and invest in transportation. Rail alone isn’t enough. What matters more is what we build around it. Are we dense enough to be brilliant?
