My newest Bloomberg piece: School Reopening Is a Disaster in the Making From New York City to Florida, students and teachers […]

Yesterday I wrote a new Bloomberg column in which I took Trump seriously when he repeated for the nth time that our problem is that we do too many tests, which thus shows too many confirmed COVID-19 cases. And when I say “seriously”, what I mean is I thought through what kind of model of […]

I just wrote a new Bloomberg column about how I was wrong to predict 600 daily deaths by COVID in Florida by now; right now it’s at 184. But the fishy data coming out of Florida makes me think I’m not as wrong as I wish I were. Narrow definitions of what counts as a […]

Hey guys, Let’s face it, the federal response to COVID has been counterproductive. We’re on our own. In my newest Bloomberg piece, I suggest that we should crowdsource CO2 levels in places like schools, airports, and buildings where people work, so we know the ventilation is good: People need a way to crowdsource data on […]

A few months ago (it was published March 19th), Politico asked me and other “thought leaders” to predict how Coronavirus would change the world. The answers are here, and include various fancy people predicting “a decline in polarization”, “less individualism”, “a healthier digital lifestyle”, “science reigns again,” and my personal favorite, Tom Nichols’s prediction that […]

In my newest Bloomberg column, I wrote about a boy named Hadrien, interested in studying engineering, whose future has been put in doubt by the International Baccalaureate Organization’s new grading algorithm, which assigns grade in a secret, powerful, and destructive manner.

I’ve spent a bunch of time worried about Florida and COVID in the past few months, partly because my grandma lived there for a number of years and so I spent a bunch of time there growing up. It’s a really vulnerable place, in some ways more so than Manhattan. And according to the data, […]

You guys might have been wondering what happened to me! Well the answer is I moved to Somerville, MA temporarily, and it takes a TON of work to move, especially when you haven’t moved in 15 years! Side note: I discovered I am a major hoarder in the categories of clothing, shoes, and yarn. This […]

Here’s my newest Bloomberg column, in which I argue that we’ve already done the data work behind defunding the police, because “crime risk scores” predict police, and not in a good way: Here’s an Algorithm for Defunding the Police Crime-risk scores reveal the problems that society has shunted onto law enforcement.
