Here are the results of my first use of OpenAI’s Deep Research tool. I asked for information that I know well – and in which inaccurate research has been published. It did a great job and relied substantially on my own research. But it also went beyond my list – identifying protest petition statutes in […]

Yes in God’s backyard… and yes up to three stories?
With state legislative seasons in full swing, a picture of the landscape of land use reform is emerging. One dynamic I’ve been tracking: Yes In God’s Back Yard (YIGBY) bills, designed to allow religious organizations (and sometimes other nonprofits) to easily use their land to build housing, are still in vogue with lawmakers.

Morton’s Fork and urbanism
I recently read about an interesting logical fallacy: the Morton’s fork fallacy, in which a conclusion “is drawn in several different ways that contradict each other.” The original “Morton” was a medieval tax collector who, according to legend, believed that someone who spent lavishly you were rich and could afford higher taxes, but that someone […]

How much housing does Massachusetts build?
In a recent post, I revealed the 91 large cities and counties that consistently fail to report complete data to the federal Building Permit Survey (BPS).

For example, film critic John Podhoretz tweeted: “Yeah, nothing easier that taking the subway from […]

Neutralizing the Objector Lawsuit
Builders seeking approval for proposed real estate developments must in almost all American localities navigate a complex series of required procedural steps, but for those who persevere and succeed in obtaining a permit, one eleventh-hour device can bring all those efforts to naught: the objector lawsuit. Easy to file but difficult to resolve, lawsuits by […]

By Salim Furth
We identified large 91 cities and counties that regularly fail to report their building permits to the Census Bureau – including some surprising culprits.

Decriminalizing Jaywalking: The Early Data
In recent years, three states have legalized or decriminalized jaywalking: Virginia and Nevada did so in early 2021, and California legalized jaywalking at the start of 2023. The traditional argument for anti-jaywalking laws is that they protect pedestrians from themselves, by limiting their ability to walk in dangerous traffic conditions. If this argument made sense, […]
