As pit bulls have become more common, their representation in dog fatalities has grown, as have the per capita rates of dog fatalities and injuries.
In 1979-1998, pit bulls were a quarter as common as now, but they were still responsible for a large % of deaths. The premiere "aggressive dog" at the time was the Rottweiler, and despite its reputation, bad owners, and far greater numbers, it didn't kill as many as the pit bull.
And this isn't due to mix-ups. We used to have data separating purebred pit bulls from crossbred ones.
Crossbred pit bulls are fortunately now more common, but they used to be the less common variety. It's fortunate because the mixing means less violence per dog.
More recently, in the deadliest states with respect to dog attacks, it's clear that pit bulls are to blame for most dog fatalities.
A major part of why pit bulls are such outliers is that, where we have data, it appears they kill people at a wider - older - range of ages.
52% of all dog fatalities are of people ≥10 while 72% of pit bull fatalities are, versus 28% for the ~94% from all other breeds combined
Despite aggressive dogs and bad owners being a thing forever, the switch from Rottweilers and the like to the pit bull has been destructive for this reason
Dog fatalities used to be a problem for children alone, but due to pit bulls they are now largely a problem for people ≥10
Pit bulls are not deadly because they're strong. Many breeds are stronger. They are deadly for the reason fighters want them: tenacity.
"Pit Bull" here is a mix, but the broader label applies to the APBT, American Staffordshire Terrier, and the Staffordshire Bull Terrier.
This is something that's difficult for police to get dogs to adopt through the rigorous training they're subjected to. Most fail! Because it's been bred into pit bulls, it's much more reliably observed in that breed.
Other BSL'd breeds are also often extremely tenacious.
Here's a previous post with the relative risks of fatalities by breed.
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!
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.
Second, they make job applications in expensive, so people start spending less time shooting off applications.
More, rapidly-produced job applications becomes the norm.
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.
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.
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🧵
Is it perhaps because of a racial composition change?
No.
Different races tend to have similar testosterone levels and trends within groups are similar.
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.
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.
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
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.
If you want to add beds to a hospital, build facilities, purchase diagnostic scanners, but you live somewhere with CON laws, then you have to prove you're not creating competition for other medical facilities in the area, which is often the whole state.
No. Competition. Allowed.
The idea behind these laws is that people will spend excessively on healthcare, so to combat that, we'll have people report if there's more spending needed before approving it.
