prior probability

Sunday fun-day, right? Below are two of my favorite songs from 2016, when this blog was just three years old. In the Anglo-American world, 2016 was also the year of Brexit and Trump and the amazing year all our asinine pundits were proved wrong, even the much-touted Nate Silver! As an aside, if these videos were made today (in our troubled coronavirus era), I am pretty sure all the beautiful models and artists would be more socially distanced! Also, as a further aside, while we are on the subject of 2016, check out my one and only published paper from that year “Probabilistic Interpretation.”

I nominate John Ioannidis, Gerg Gigerenzer, Jacob Cohen, and (now) @aubreyclayton! Somehow, I missed Aubrey Clayton’s powerful take-down of standard statistics and “statistical significance,” which was published in Issue #74 of Nautilus (August 1, 2019). Among other things, Clayton explains why probability without priors is impossible, and he presents three striking examples of bad statistical reasoning–the Sally Clark case, cancer screening, and a bullshit study that was published in the journal Science–and shows step-by-step why Bayesian reasoning outperforms so-called significance testing every time. I only wish to add that Bayesian reasoning also solves many so-called “proof paradoxes” in law, including Larry Tribe’s blue bus problem and the paradox of the gatecrasher. On the blue bus problem, check out my full-length law review article “Visualizing Probabilistic Proof,” and for the so-called paradox of the gatecrasher, check out my October 2014 blog post titled “The paradox of the gatecrasher is not a paradox.” Any questions?

How should we teach “business law” to undergraduate students? What topics should we cover and in what order? My colleague (and new friend!) Ralph Flick created a beautiful, color-coded visualization (pictured below) of his business law survey course. As an aside, I am huge fan of visualizations, as my Summer A Syllabus on Tiger King can attest to!

If you use a Fitbit or Apple Watch or other similar device to monitor your exercise, diet, or sleep routines, then you already know that those devices generate a lot of data about the state of your health, including weight/body fat percentage, heart rate, blood pressure, and sleep quality. But who owns that data? You? The manufacturer of the device? What about your employer, if you are a pro-athlete, for example? This is precisely the question that my colleagues John Holden and Kimberly Houser pose in their work in progress “Data Trusts, Betting & Biometrics” — my favorite (thus far) paper of the yearly ALSB  conference that I have been attending this week. #ALSB2020

Today is Jamaica Independence Day 🇯🇲, and my youngest daughter Adys Ann turns seven today …

Although his decision to invade Iraq was probably the single-worst decision in our nation’s history, I have to hand it to George W. Bush (a fugitive war criminal), his eulogy for John Lewis was one of the best …

I will be attending the annual meeting of the Academy of Legal Studies in Business (ALSB) this week. Among other things, I will be presenting my work-in-progess “Breaking Bad Promises” on Monday morning, August 3. (See top screenshot, which is below the fold.) Although I have presented this paper at conferences and workshops before, I will be addressing a new aspect of the “breaking bad problem” (i.e. promises to perform an illegal or immoral act): the relationship between illegal agreements and criminal conspiracy laws. Also, on Tuesday afternoon, August 4, my teaching assistants and I will be presenting our paper titled “Teaching Tiger King.” (See middle screenshot; also below the fold.) In addition, I will be moderating a panel on Friday morning (bottom screenshot) and attending a wide variety of scholarly panels all week … Continue reading →
