Compared to twenty years ago, kids are eating some types of ultraprocessed foods more and some types less🧵

For example, one thing there's proportionally less of is sugar-sweetened beverage consumption. Meanwhile, there's relatively greater sweet snack consumption.

Overall, the ultraprocessed food (UPF) consumption share is up across young ages to similar degrees.

The increase is definitely there, but it isn't dramatic. For example, going from 61% to 67.5% is an 11% increase in twenty years.

The increase in consumption is not differentiated by the sex of children.

In other words, boys and girls are both eating a bit more ultraprocessed food.

Today the President has provided an outline for the direction of medication pricing over the next four years.

This is related to broader deregulatory efforts that are likely going to end up making Americans a lot better off🧵

The executive order starts off by noting the administration's efforts to reduce drug prices the first time around.

These efforts were centered around deregulation and promoting transparency in the concentrated, often-cartelized and captured healthcare marketplace.

A few days ago, an opinion piece by @ezraklein went out in the @nytimes.

It described how people in the Biden administration wished that they'd just gone a little faster.

It's good they believe this, because it's true: they went very slowly.

The Flynn Effect🧵

People tend to understand it as an indication that earlier generations were a lot less intelligent than we moderns.

Or if they're read up on the literature, they now think things are reversing.

Both are wrong! Take a look at this chart of Norwegian data:

If you don't understand what those tests are like, here are some example questions:

What we see over time with the Flynn Effect (the increase in IQ scores) and the Reverse Flynn Effect (the more recent decrease in IQ scores) is that both are due to something really boring: people interpreting tests differently than they used to.

A new UBI experiment has come out.

This time... it seems like it worked🧵

The study took place in Germany and was centered on the experiences of 107 people aged 21-40 who lived alone and had earnings between €1,100 and €2,600 per month.

The experiment provided them with €1,200 per month for three full years.

Controls (N = 1,580) earned €10 for sticking with the program and another €30 if they made it the whole way.

There was no attrition in the treatment group, but 29% of the control group dropped out by the end of the study.

Attrition seemed unselective. So onto results!

Many women have found that they get pregnant more easily after getting on GLP-1 drugs.

But women aren't the only ones noticing improved fertility:

There's now clinical trial evidence that GLP-1s improve sperm parameters.

The largest clinical trial published so far on this subject came out in 2023. It involved 110 men aged 18-35 with metabolic hypogonadism being sorted into one of three conditions:

A: The group seeking fatherhood.
B: The group not seeking fatherhood.
C: The group of already-dads.

The men in Group A were explicitly given the fertility drugs urofollitropin three times a week and human chorionic gonadotropin twice a week.

Group B received the GLP-1 drug liraglutide.

Group C received daily transdermal testosterone.

This goes on for four months.

A brilliant new paper found that brain drain can literally kill🧵

The paper is all about what happened when Sweden's doctors decided to pack up their stethoscopes and scalpels and go to work in another country.

The story begins with the curious economic divergence of Norway and Sweden.

Over time, Norway has become vastly richer than Sweden primarily because it's become Europe's premiere petrostate.

With surging oil prices, their GDP leaped ahead at a staggering pace:

With rising wages due to the oil sector, wages elsewhere in the economy have to rise, even in sectors that didn't get more productive

If those wages didn't rise, no one would want to do those jobs: Butlers in different countries equally butle, but are paid very different amounts
