Changes to the Bar exam so far don't seem to have made a dent in the race differences in performance on it.

How large are these differences? In the latest year, 2022, the Black-White gap in California Bar pass rates was 0.97 SDs.

And this matters because we expect a threshold Image
to practice (the Bar exam) to reduce subsequent performance gaps.

But how much should those gaps be reduced?

Let's simulate to find out!

@_twolfram recently provided an estimate for British lawyers' IQs of 110.31: sciencedirect.com/science/articl….

Let's go ahead and assume
there's a threshold that's 0.67 SDs (10 points) above the higher-performing of two groups with equal variances who are separated by 0.97 d.

With simulated group sizes of one million persons each, the mean differences decline, and the SDs do too. The new gap is 0.412 d. Image
But we know that the 0.97 d gap is an underestimate due to range restriction.

Using MBE scores, it looks like the unrestricted gap should be more like 1.22 d. That leaves us with a 0.537 d gap above the threshold.

Do we have subsequent performance measures?

Yes! We have three:
- Complaints made against attorneys
- Probations
- Disbarments

For men, the gaps, in order, are 0.576, 0.513, and 0.564 d. For women, the gaps are 0.576, 0.286, and 0.286 d.

Men fit expectations and women apparently needed less discipline. Source: https://board.calba...
These gaps probably replicate nationally.

For example, here are Texas pass rates from 2004 - a 0.961 d Black-White first-pass gap. The 2006 update to these figures raised the gap to 0.969 d. Source: https://ble.texas.g...Image
Those figures are basically in line with LSAC's national study of Bar exam pass rates. Image
And those are basically in line with New York's gaps. Image
And this should probably be expected, since tests measure the same things. Image
Since all of the people included in these statistics went to ABA-accredited schools, they all had the opportunity to learn what was required to perform well on these tests.

But just like the Step examinations for medical doctors, the gaps on the tests and in real life remain.

Do you know the most patriotic drink you can have today?

It's a wine from a little island controlled by Portugal.

It was definitely the Founding Fathers' favorite drink, and it's likely the most important drink in American—and thus world—history.

Let's talk about Madeira🧵Image
Our Colonial forebears "swam in a sea of booze from breakfast till bedtime".

It was safer than drinking the water, but that wasn't the only reason they did it.

They were also rowdy, young, and they liked to drink. When it came time to party, they showed it! Image
Before the Revolution, the British vigorously curtailed the import of French and Spanish wines into the colonies.

So, what could the colonists drink? Rum, brandy, spirits, and their favorite: wine from the Portuguese island of Madeira! Image

Amy Wax got in trouble for remarking that she'd not seen a Black student in the top quarter of a Penn Law class.

Thanks to hacked Columbia data, we can see that she was...

Probably right!

In the decade before her statement, there were just two top-25% Black students. Image
It is *totally* plausible that she never met these students. And it's also plausible that she rarely saw Black students in the top *half*, because each year, the number of them was just 1-4.

But, despite being 8% of the class, they were ~40% of the bottom 10%-ranked students: Image
Note: Penn is on-par/slightly less elite than Columbia, so it's likely that the Black students there were somewhat *worse*, as the article notes, making her claims more likely.

This all comes from @zagrebbi's latest article. It's well worth a read!

And there it is:

The Supreme Court has decided to maintain Birthright Citizenship.
Big day if you think Roe v. Wade was correctly decided.

My favorite part (note that I've only read 150 pages so far) was Thomas explaining that, no, the Founding g Fathers did not adopt the English feudal system.

This fact was clearly lost on the other side. Image
The Court's reliance on a random remark from a case that ultimately didn't even produce lasting changes raises the question of whether that sort of thing even matters.

Why shouldn't I cite the Dred Scott case as the law of the land? Image

The medical community has cured a mountain of diseases in the past several decades.

Diseases cured thread🧵

In 2013, hepatitis C was cured by direct-acting antivirals. Image
Peptic ulcers are now curable in more than 90% of patients via antibiotic triple/quad therapy (1994). Image
Sickle cell anemia was cured in 2023 for >96% of patients. Image

Because America has made the wise decision to compensate blood donors, it has ended up supplying some 70% of the world's blood plasma.

This is one of America's top exports, and each year, America saves hundreds of thousands of lives because it does this. Image
Some people argue against plasma donation on the basis of it being disproportionately used by poorer people

They say it's exploitative: they feel that selling something your body makes is wrong if disparate in ways they care about

But it's a lifesaver!

There's also research indicating that plasma donation can be healthy!

(And there's more indicating that, with compensation, it might reduce crime in the local area.)

It's Pride Month, so let's talk about why San Francisco is so incredibly gay.

Military policy.

🧵 Image
In 1982, Randy Shilts published his biography of Harvey Milk, entitled "The Mayor of Castro Street".

For those who don't know, Harvey Milk was the first open homosexual to be voted into public office in the state of California.

He was on the San Francisco Board of Supervisors. Image
The biography contains a fair bit of background, not just about Harvey Milk, but about San Francisco's gay community more generally.

In its early years, San Francisco attracted large waves of mainly male migrants motivated by the promise of gold in California. Image
