Screen time and early adolescent mental health, academic, and social outcomes in 9- and 10- year old children: Utilizing the Adolescent Brain Cognitive Development (ABCD) Study
Katie Paulich et al.
PLoS ONE, September 2021

We investigate relationships between screen time and mental health, behavioral problems, academic performance, sleep habits, and peer relationships by conducting a series of correlation and regression analyses, controlling for SES and race/ethnicity. We find that more screen time is moderately associated with worse mental health, increased behavioral problems, decreased academic performance, and poorer sleep, but heightened quality of peer relationships. However, effect sizes associated with screen time and the various outcomes were modest; SES was more strongly associated with each outcome measure. Our analyses do not establish causality and the small effect sizes observed suggest that increased screen time is unlikely to be directly harmful to 9-and-10-year-old children.

More on Hanania and expertise

What I like about his argument is the emphasis on the costs of getting this wrong: if we rely on unproven expertise, the costs can be horrific. And it isn’t like Afghanistan was an outlier, an anomaly. I believe there’s good evidence to suggest that, in the UK, the recession or recessions following the 2008 financial crisis wouldn’t have been so prolonged had the government not leaned in on austerity policy as it did; even from an economic point of view, it wasn’t a good decision. (I have strong opinions on austerity more generally, of course, but we needn’t cloud this point with what could be misconstrued as politics.)


(#76gq4oa) Oh really? I guess that’s my fault, adding that second hashtag. Re ideas, I was wondering about that Blog button, beside Reply: couldn’t we just treat a blog post like any other link? That we reply to, starting conversations?


Hanson on elite influence on policy:

”… It seems to me that policy does tend to be overly trusting of elites and their status-gossip system, and overly punitive and disrespectful of rival groups. For example, policy pushes us to pick docs, lawyers, and other prestigious professionals based more on the prestige of their affiliations, and less on track records or incentives. Business does seem greatly overly regulated, and taxes seem overly punitive. And policy seems to rely too much on the consensus of elite gossip, relative to more accurate sources like experts or prediction markets…”


(#xrtbbhq) Looks like GNU social is now advocating a Docker based deployment; might opt for that instead, actually. That’s the route I went down, hosting vaultwarden on my Pi 3A, and I’m pretty happy with the results, to date.


Instagram CEO Mosseri on its value to society: an article in need of an editor, but worth reading simply because it’s a window on the mind of a person at the heart of broken social media. This isn’t just Zuck.

That he thinks the complaints stem from being misquoted is at once laughable and horrifying. This company is not only willfully ignoring the objective harm it is doing, it’s actively peddling a narrative advocating an intrinsic value above even that of the devices that run it.

Hubris. But hubris causing direct harm to millions.


@prologic (#qc5b6ba) It wasn’t a dig, mate, honest! You’re doing great work, and it takes but a moment for interested parties to find their way here, I’m sure. :-)

That said, we could use an artist or two on the roster, you aren’t wrong. ;-)



”… At times the CDC seemed more interested in its own “intellectual property” than in saving lives. In a jaw-dropping section, Dr. Gottlieb writes that “companies seeking to make the test kits described extended negotiations with the CDC that stretched for weeks as the agency made sure that the contracts protected its inventions.” When every day of delay could mean thousands of lives lost down the line, the CDC was dickering over test royalties…”
