“Haidt cites 476 studies in his book that seem to represent an overwhelming case. But two-thirds of them were published before 2010, or before the period that Haidt focuses on in the book. Only 22 of them have data on either heavy social media use or serious mental issues among adolescents, and none have data on both.
There are a few good studies cited in the book. For example, one co-authored by psychologist Jean Twenge uses a large and carefully selected sample with a high response rate. It employs exploratory data analysis rather than cookbook statistical routines.
Unfortunately for Haidt, that study undercuts his claim. The authors did find that heavy television watchers, video game players, and computer and phone users were less happy. But the similar graphs for these four ways of spending time suggest that the specific activity didn’t matter. This study actually suggests that spending an excessive amount of time in front of any one type of screen is unhealthy—not that there’s anything uniquely dangerous about social media.”
“Chronic absenteeism has increased across the board—affecting both wealthier and poorer districts. According to new data from the AEI, absenteeism increased from 10 percent in 2019 to 19 percent in 2023 in the richest school districts. In the poorest districts, absenteeism increased from 19 percent to a staggering 32 percent over the same time period.
Surprisingly, the length of school closures didn’t seem to impact the increase in absenteeism that much. Districts that were closed the longest saw absenteeism increase 12 percent, while those with the shortest closures saw a 10 percent increase.
However, things were even worse in years closer to pandemic closures. In 2022, for example, 28 percent of students were chronically absent. Overall, absenteeism rates fell from the 2021-2022 school year to the 2022-2023 school year in 33 of the 39 states reporting data. ”
“Since seizing power in a coup last year, Niger’s junta has been strengthening military ties with Russia while turning away from the US and France.
Last month, the junta said it was ending an accord with the US that allowed military personnel and civilian staff from the US Department of Defense to operate in Niger.
France, Niger’s former colonial ruler, withdrew its troops from the African nation at the end of 2023.
Niger’s junta-controlled neighbors Mali and Burkina Faso have also turned to Russia for military support, deepening Western concerns about Russia’s expanding influence in Africa’s troubled Sahel region that has battled a spate of coups and Islamist insurgents for years.”
“The 53-car freight train that derailed in East Palestine, Ohio, last year was operated by a crew of three men, none of whom were able to prevent the cascade of mechanical and communication failures that led to the unfortunate accident.
In response to that crash, the federal Department of Transportation announced on Tuesday a new policy requiring freight trains to operate with at least two-person crews—a mandate that the Biden administration says will enhance rail safety.
If you’ve passed first grade, you might now find yourself asking a rather basic question: Isn’t three more than two?
Rest assured that it is. However, in Washington, the policy-making calculus often relies on fuzzy math that is heavily influenced by the pull of special interests and the strong sense of do-something-ism.
Both are on display in the new freight railroad mandate. The derailment in East Palestine was bad, and something must be done. This is something, so now it is being done—and bonus points can be scored because doing this specific thing will please the Biden administration’s labor union allies, which have been lobbying the government for years to impose exactly this two-person crew mandate.
On Tuesday, Transportation Secretary Pete Buttigieg said it should be “common sense” that “large freight trains, some of which can be over three miles long, should have at least two crew members on board.”
The length of the train has absolutely nothing to do with it, but Buttigieg is gesturing toward the idea that a second person on board could bring the train to a halt if the driver is somehow incapacitated. And, indeed, it was longstanding railroading practice to have multiple people in the cab of freight trains for exactly this reason.
These days, however, it is automation and not a backup engineer that is responsible for a dramatic decline in railway accidents and injuries. Thanks to positive train control (PTC)—essentially a computer-based override system that monitors speed and track signals to avert collisions, and which railroads have been mandated by Congress to use since 2008—rail accidents have fallen by 30 percent while employee injuries are down 40 percent since 2000, according to data from the Association of American Railroads (AAR), an industry group.
Additionally, Buttigieg’s claim about “common sense” comports with neither the specifics of the East Palestine accident nor recent governmental reviews of the two-person crew mandate.
The Federal Railroad Administration spent three years investigating a proposed two-person crew mandate before concluding in 2019 that the rule was not “necessary or appropriate for railroad operations to be conducted safely,” largely because of the safety gains already made by automation. More recently, Congress considered—but, notably, did not enact—a two-member crew mandate in the wake of the East Palestine derailment.
As for the the East Palestine incident, having a crew of 10 people driving the train likely wouldn’t have made any difference. The crash was caused by an overheated wheel bearing, which failed and derailed the train as the crew was attempting to bring it to a stop. The three-person crew should have been alerted to the problem sooner, but at least one track-side detector meant to spot the wheel issue was not working properly.”
“trade doesn’t need to balance. I have a trade deficit with my supermarket. They get more of my money every year. So, what? I don’t “lose.” I get food without having to grow it myself.
That’s a win for me and the food producer regardless of whether the food was grown locally or came from Mexico.
“Imports are great,” says Lincicome. “It means I can focus on what I want to do for a living and not go make my own food or make my own clothes. I can use those savings and buy other things that makes me better off.”
As long as trade is voluntary, trade is a win for both parties. It has to be; neither side would agree to it unless they think they get something out of the deal.”
