The FBI has finally released crime statistics for 2023!
Let's have a short thread.
First thing up is recent violent crime trends:
Now let's focus in on homicides.
The homicide statistics split by race show the same distribution they have for years.
As with every crime, it's still men doing the killing, but it's also largely men doing the dying.
What about Hispanics? Their data is still a mess, but here it is if you're interested.
The age-crime curve last year looked pretty typical. How about this year?
Same as always. Victims and offenders still have highly similar, relatively young ages.
Everything else, from locations to motives to weapons is pretty similar to previous years. What's different is that the OP might show incorrect numbers.
For the past two years, the FBI has silently updated their numbers after about two weeks.
You can use the web archive to see that the data from the OP is the data shown at release last year, and the data from 2023 is the 2022 data with the FBI's suggested reductions (i.e., -11.6% homicides, -2.8% aggravated assaults, -0.3% robberies, etc.).
But you can see on their site now that they've adjusted the numbers up, so the reduction they suggested has brought us down to a figure that's less impressive than my chart shows. The difference isn't huge so I showed the OP without updating to their new data.
For reference, 2022 as reported then had a homicide rate of 6.3/100k, and they silently updated that to 7.48/100k. The 2023 data they provided today actually has a murder rate of 6.61/100k, higher than last year's initially-reported number, but lower than the updated number. To make matters worse, if you use their Expanded Homicides Report, you get a rate of 5.94 for 2022 and 5.24 for 2023.
Methodology matters and we get to see inconsistency in this year's data, not even data that's been updated or anything. It's a mess, so take everything with a grain of salt and, in the interest of caution, only interpret trends. Trends are mostly common between all data sources even if the absolute magnitudes are off, constantly updated, etc.
Why do identical twins have such similar personalities?
Is it because they're reared together? Is it because people treat them alike due to their visual similarity?
Nope! Neither theory holds water.
Despite looking as similar as identical twins and being reared apart, look-alikes are not similar like identical twins are. In fact, they're no more similar than unrelated people.
This makes sense: they're only minimally more genetically similar than regular unrelated people.
The other thing is that twins reared apart and together have similarly similar personalities.
In fact, there might be a negative environmental effect going on, where twins reared together try to distinguish their personalities more!
Smart people tend to earn higher educations and higher incomes, and to work in more prestigious occupations.
This holds for people from excellent family backgrounds (Utopian Sample) and comparing siblings from the same families!
This is true, meaningful, and the causal relationship runs strongly from IQ to SES, with little independent influence of SES. Just look at how similar the overall result and the within-family results are!
But also look at fertility in this table: quite the reverse!
The reason this is hard to explain has to do with the fact that kids objectively have more similar environments to one another than to their parents.
In fact, for a cultural theory to recapitulate regression to the mean across generations, these things would need to differ!
Another fact that speaks against a cultural explanation is that the length of contact between fathers and sons doesn't matter for how correlated they are in status.
We can see this by leveraging the ages parents die at relative to said sons.
The internet gives everyone access to unlimited information, learning tools, and the new digital economy, so One Laptop Per Child should have major benefits.
The reality:
Another study just failed to find effects on academic performance.
This is one of those findings that's so much more damning than it at first appears.
The reason being, laptop access genuinely provides people with more information than was available to any kid at any previous generation in history.
If access was the issue, this resolves it.
And yet, nothing happens
This implementation of the program was more limited than other ones that we've already seen evaluations for though. The laptops were not Windows-based and didn't have internet, so no games, but non-infinite info too
So, at least in this propensity score- or age-matched data, there's no reason to chalk the benefit up to the weight loss effects.
This is a hint though, not definitive. Another hint is that benefits were observed in short trials, meaning likely before significant weight loss.
We can be doubly certain about that last hint because diabetics tend to lose less weight than non-diabetics, and all of the observed benefit has so far been observed in diabetic cohorts, not non-diabetic ones (though those directionally show benefits).
