Turns out the science saying screen time is bad isn’t science – TechCrunch

A new study is making waves in the worlds of tech and psychology by questioning the basis of thousands of papers and analyses with conflicting conclusions on the effect of screen time on well-being. The researchers claim is that the science doesn’t agree because it’s bad science. So is screen time good or bad? It’s not that simple.
The conclusions only make the mildest of claims about screen time, essentially that as defined it has about as much effect on well-being as potato consumption. Instinctively we may feel that not to be true; technology surely has a greater effect than that — but if it does, we haven’t found a way to judge it accurately.
The paper, by Oxford scientists Amy Orben and Andrew Przybylski, amounts to a sort of king-sized meta-analysis of studies that come to some conclusion about the relationship between technology and well-being among young people.
Their concern was that the large data sets and statistical methods employed by researchers looking into the question — for example, thousands and thousands of survey responses interacting with weeks of tracking data for each respondent — allowed for anomalies or false positives to be claimed as significant conclusions. It’s not that people are doing this on purpose necessarily, only that it’s a natural result of the approach many are taking.
“Unfortunately,” write the researchers in the paper, “the large number of participants in these designs means that small effects are easily publishable and, if positive, garner outsized press and policy attention.” (We’re a part of that equation, of course, but speaking for myself at least I try to include a grain of salt with such studies, indeed with this one as well.)
In order to show this, the researchers essentially redid the statistical analysis for several of these large data sets (Orben explains the process here), but instead of only choosing one result to present, they collected all the plausible ones they could find.
For example, imagine a study where the app use of a group of kids was tracked, and they were surveyed regularly on a variety of measures. The resulting (fictitious, I hasten to add) paper might say it found kids who use Instagram for more than two hours a day are three times as likely to suffer depressive episodes or suicidal ideations. What the paper doesn’t say, and which this new analysis could show, is that the bottom quartile is far more likely to suffer from ADHD, or the top five percent reported feeling they had a strong support network.
In the new study, any and all statistically significant results like those I just made up are detected and compared with one another. Maybe a study came out six months later that found the exact opposite in terms of ADHD but also didn’t state it as a conclusion.
This figure from the paper shows a few example behaviors that have more or less of an effect on well-being.
Ultimately what the Oxford study found was that there is no consistent good or bad effect, and although a very slight negative effect was noted, it was small enough that factors like having a single parent or needing to wear glasses were far more important.
Yet, and this is important to understand, the study does not conclude that technology has no negative or positive effect; such a broad conclusion would be untenable on its face. The data it rounds up are (as some experts point out with no ill will toward the paper) simply inadequate to the task and technology use is too variable to reduce to a single factor. Its conclusion is that studies so far have in fact been inconclusive and we need to go back to the drawing board.
“The nuanced picture provided by these results is in line with previous psychological and epidemiological research suggesting that the associations between digital screen-time and child outcomes are not as simple as many might think,” the researchers write.
Could, for example, social media use affect self-worth, either positively or negatively? Could be! But the ways that scientists have gone about trying to find out have, it seems, been inadequate.
In the future, the authors suggest, researchers should not only design their experiments more carefully, but be more transparent about their analysis. By committing to document all significant links in the data set they create, whether they fit the narrative or hypothesis or go against it, researchers show that they have not rigged the study from the start. Designing and iterating with this responsibility in mind will produce better studies and perhaps even some real conclusions.
What should parents, teachers, siblings and others take away from this? Not anything about screen time or whether tech is good or bad, certainly. Rather let it be another instance of the frequently learned lesson that science is a work in progress and must be considered very critically before application.
Your kid is an individual, and things like social media and technology affect them differently from other kids; it may very well be that your informed opinion of their character and habits, tempered with that of a teacher or psychologist, is far more accurate than the “latest study.”
Orben and Przybylski’s study, “The association between adolescent well-being and digital technology use,” appears in today’s issue of the journal Nature Human Behaviour.

2024 Kia EV9 Three-Row Electric SUV Reveals Range, Power And Tech

The EV9 will be available with two different battery sizes and three different configurations of electric motors. The Standard RWD option receives a 76.1 kWh battery pack, while a larger 99.8 kWh battery powers both the Long Range RWD and AWD configurations. The Long Range RWD is the least powerful, with a 201 horsepower motor at the rear axle that pushes it from zero to 60 mph in an extremely lethargic 9.4 seconds. The estimated range for this model is 336 miles on a full charge.
Do note that the estimated range was calculated using the more lenient WLTP method. When the range estimate is recalculated using the stricter EPA method in the U.S., expect that 336-mile figure to drop below 300 miles. Next up is the Standard RWD model with its 214 horsepower motor. With more horsepower than the long-range version and a smaller, lighter battery pack, this model achieves zero to 60 mph in 8.2 seconds. Better, but still pretty pokey. Unfortunately, Kia did not provide a range estimate for this model.
Lastly, we have the AWD variant, which packs a 371-horsepower punch from dual motors that scoot it from zero to 60 mph in a respectable 6.0 seconds flat. Interestingly, the automaker has indicated that an optional Boost feature will be available for purchase at the Kia Connect Store, which increases torque and facilitates a faster zero to 60 mph time of just 5.3 seconds. Once again, no range estimate was provided for the AWD model.

EV Maker Lucid Plans Widespread Layoffs In Effort To Cut Costs

Beyond the letter sent to staff, Lucid shared some details about the upcoming layoffs in a regulatory filing, the most notable of which is that it will eat $24 million to $30 million as a result of its restructuring due to expenses like severance pay for laid-off workers. Executives aren’t immune from these cutoffs nor are contractors. Assuming everything goes according to plan, the entire debacle will be wrapped up by the end of the company’s second quarter.
The move isn’t surprising in light of Lucid’s February 2023 announcement that it needs to reduce its spending. The company was hit by a sharp drop in demand for its luxury EV in recent months, and it entered the new year in a weak position amid the wider economic uncertainty many face in our largely post-pandemic days.
The news came only a few weeks after the company’s biggest competitor, Tesla, announced sharp price cuts that made its already popular EVs even more attractive to consumers. The automotive market was hit particularly hard by the supply chain disruption that occurred during the height of the pandemic, leaving some new cars benched while used car prices climbed and manufacturers made hard compromises in the name of getting units out the door.

Traditional Custom Keyboard With Future In Sight

If the form factor of the Compact Touch appeals but the price is too high, there are some alternatives to consider. The first would be the HHKB, the very first keyboard line with this particular key arrangement. The latest HHKB Hybrid costs $266.62, uses its signature Topre electrostatic rubber domes instead of mechanical key switches, and adds USB-C and Bluetooth connectivity. It doesn’t have an internal rechargeable battery but uses two AA batteries for power. It can pair up to four devices, and switch between them with keyboard shortcuts.
If wireless isn’t necessary, Mode Designs’ Envoy is a 65% form factor in aluminum or polycarbonate chassis, with customizable options for accent pieces, case color, weight, plate, and PCB. It starts from $189 without keycaps, switches, or stabilizers. This keyboard also has a futuristic design, a rubber mounting system that can be adjusted to be firmer or more flexy, and is programmable using QMK or VIA, the two most widely used firmware sets for custom mechanical keyboards.
The Keychron Q2 costs $209.99 with keycaps, switches, and stabilizers and has a 65% layout with an island-style arrow cluster, multiple color options, and the option for a rotary encoder. It uses a double gasket design for a softer typing feel with a little flex, and also uses QMK or VIA to reprogram its keys. It’s also available as a barebones keyboard for $179.99, but it’s worth getting the fully-built version even if you plan on changing the switches or keycaps.
