In 2014, David Graeber wrote an article for the Guardian in which he argued "Working-class people... care more about their friends, families, and communities. In aggregate... they're just fundamentally nicer."

The Economist put up a similar article at the time.

Were they right? Image
To make his case, Graeber wove a nice little narrative together about how the rich don't need to care, so they don't, and thus they're bad at empathy and they do things like hiring out the sons and daughters of the poor to do the job when empathy is needed. Image
The meat of Graeber's case was a set of two social psychological papers.

The first was a set of three studies in which the poor appeared to outclass the rich at tasks like the Mind in the Eyes, or figuring out the emotions of people they're talking to. Image
The main effects from these studies had p-values of 0.02, 0.02, 0.04, 0.01, 0.04, 0.03, and 0.04.

This first article was severely p-hacked. To make matters worse, one of the studies featured priming and two of them used "subjective" measures of social class.
The second article was a series of seven studies that were, at times, just bizarre. Image
In the first two studies, students watched cars at a four-way intersection and tallied up how often the "upper-class" and "lower-class" cars cut off other vehicles and pedestrians.

What's an upper-class car? Beats me. It was based on student judgment.

p's = 0.046 and 0.040.
In the rest of the studies, things were similarly dodgy: almost all of the p-values were barely less than 0.05, the hypotheses were unbelievable, priming was featured, low power was abused, and liberties were taken in sampling and in defining key variablesImage
So what happens next?

Some researchers looked at these studies and the media coverage saying that the rich were bad at being empathetic, were selfish, etc. and thought

Wait, why does every field but social psychology say the opposite?
Social psychology, alongside nutrition, is a paragon of the replication crisis. Not in a good way, mind you, in the sense that remarkably many of its studies failed to replicate

Studies from outside social psychology got less coverage, but indicated the rich were more prosocial.
The researchers decided to use large, population-representative samples with objective measures of social class to figure out if the rich were more prosocial or antisocial than the poor

To start, in these two studies from Germany (SOEP) and the U.S. (CEX) they donated more often Image
This is key. The reason is, some studies had indicated that the poor donate relatively larger portions of their incomes.

But, those studies all looked at donations among those who donated. In other words, they didn't account for differences in the likelihood of donating at all.
Account for that difference, and a proposed curvilinear relationship between relative amounts of donations and poverty disappears. Now, the rich just donate more absolutely and relatively!Image
In the GSS, measures of both objective and subjective social class were available, so they could be discriminated and... it appears subjective social class might be weaker than objective social class as a predictor of at least this prosocial behavior: Image
You could argue donations aren't a great metric.

Fine.

So look at volunteering, which the rich in the SOEP were more likely to do (and do more frequently—not shown here). Image
In the GSS, the same result emerged: the objectively and subjectively rich volunteered more usually (and frequently—again, not shown here).

This happens despite the poor having more free time and the rich spending more time each week gainfully employed on average. Image
If you look in the ISSP—a large international survey covering more than 30 countries—the rich are more likely to volunteer at all in aggregate, and they volunteer more frequently, although there is some heterogeneity across countries in the frequency of volunteering relationship: Image
You could argue that the poor are more selfish because they're poor. And, OK! But even in the setting of the well-known trust game, the rich were more trusting and more trustworthy: Image
Since the poor commit more crime, are more likely to act indecent and loud, show less trusting and trustworthy behavior, and so on, we really have no reason to believe Graeber's article and so many others like it.

They were, at best, a relic of the replication crisis.
At worst—and this is likely what they really were—they were political wishcasting.

So let's not denigrate the rich, because it's not true that they deserve it.

Nature finally published it!

The Reich Lab article on genetic selection in Europe over the last 10,000 years is finally online, and it includes such interesting results as:

- Intelligence has increased
- People got lighter
- Mental disorders became less common

And more!Image
They've added some interesting simulation results that show that these changes are unlikely to have happened without directional selection, under a variety of different model assumptions. Image
They also showed that, despite pigmentation being oligogenic, selection on it was polygenic.

"[S]election for pigmentation had an equal impact on all variants in proportion to effect size." Image

I still think this is one of the most important recent papers on AI in the job market🧵

The website Freelancer added an option to generate cover letters with AI, and suddenly the quality associated with cover letters stopped predicting the odds of people getting hired!Image
LLMs do a few things to cover letters.

Firstly, they increase the quality, as measured by how well tailored they are to a given job listing. Image
Second, they make job applications in expensive, so people start spending less time shooting off applications.

More, rapidly-produced job applications becomes the norm. Image

The authors of this work now have a newer study with a nine-times larger sample!🧵

The overall result is that the rich are:

- More risk-tolerant, open to experiences, extraverted, and conscientious
- Less neurotic
- No more agreeable than normal, non-rich people Image
Now, we have a breakdown of different types of rich people!

Among those who could be classified, the majority of the rich (79%; >=€1m net worth) were self-made, with a smaller, 21% share whose wealth came primarily from inheritances. Image
How do inheritors and the self-made differ in personality?

They're both more risk-tolerant and less neurotic than the average, but the inheritor profile looks like a mixture between the overall rich and normal people, with more agreeableness, less openness, etc. Image

Why have testosterone levels been rising over time?

The testosterone levels of American men are up compared to what they used to be, but no one has a good explanation.

Let's look through some possibilities🧵 Image
Is it perhaps because of a racial composition change?

No.

Different races tend to have similar testosterone levels and trends within groups are similar. Image
Is it perhaps because of age composition change?

No.

The decline by age is much more graceful than people tend to suspect, and within each age group, levels are up without survey weighting, and in nearly all with it, they're still up. Image

Today's deregulatory news is pretty big.

The White House is taking aim at the housing shortage by deregulating housing construction🧵 Image
A big part of the American Dream was created by a massive housing boom when the troops came home

Since the Great Financial Crisis, practically everywhere has reduced the number of permits they issue for new housing

This has resulted in housing cost growth outpacing wage growth: Image
To revive the American Dream, we need to build more homes.

If we want to build more homes, we'll have to overcome a lot of different regulatory burdens.

One step is to get rid of federal regulatory burdens that straddle homebuilders and owners with lots of random costs. Image

In my latest article, I documented that the only RCT for functional medicine methods appears fraudulent🧵

Before getting into it, what's functional medicine?

It's a pseudoscience used to bilk patients by getting them on an unending cycle of tests, supplements, and more tests. Image
Functional medicine's practitioners claim that they can reveal and treat so-called "root causes" of people's health problems

These are proposed to be things like gut health, toxin burdens, and various chemical and hormonal imbalances

They find these things with unproven tests Image
If you run enough tests, you will be able to find something that looks 'off' about a patient, and if you're a functional medicine doctor, that's your 'A-ha!' moment, even if—as is usually the case—the result is just a false-positive and treating it is unlikely to do anything. Image
