Is Screen Time Good or Bad? It's Not That Simple (techcrunch.com) 43
TechCrunch's Devin Coldeway picks apart a new study by Oxford scientists that questions 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," Coldeway writes. "So is screen time good or bad? It's not that simple." From the report: 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."
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. [...] 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. "[T]he study does not conclude that technology has no negative or positive effect; such a broad conclusion would be untenable on its face," Coldeway writes. "The data it rounds up are 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 bee inconclusive and we need to go back to the drawing board."

Screen time is artificial (Score:1)
It's always quality of content. We never worry about kids having too much book time these days. But novels used to be considered a waste of time, it was time that could be used learning a trade or honing essential skills needed for survival on a homestead. How does some fanciful fantasy help you slaughter a hog or get the harvest out of the ground? And let's not forget evil books have been banned and burned in the not too distant past.

We have the Victorian idea of the good child. Who stays out of trouble, because they have their head in a book. Now this idea looks good on a Norman Rockwell painting, but even the heavy reader kid, will put down the book and get into trouble.

If you calculate 1000 arbitrary correlations, you can expect a random 10 results to be significant to p1%. Let people publish only the interesting ones, and you get a flawed picture. This is why we need verification studies; such wide-sweeping big data analyses are good for picking up interesting questions, but for statistical reasons, you shouldn't necessarily trust the answer.

too much screen time is bad, the question is what is too much?

as always it boils down to a healty balance; if the only thing you know and have is a screen, that's not a good situation.

Some children are fine. Some children are not.
I have two children. My eldest (6) gets totally thoroughly addicted to video. As soon as he has a little bit, he just wants to watch more and more and more. My youngest one (4) will watch a little, get bored, play outside, maybe go back to it. This has always been true, ever since they were 1.
My eldest one will keep watching forgetting all about eating, peeing, or whatever. All those needs will literally jump at him at the same time, and he will routinely enter a major destructive tantrum when the video is stopped.
As a parent, I had to go for a video-free life. They are allowed very very little video on week ends, but that's it. Any more than that and my 6 year old will just. Go. Nuts. Asking for it every moment of the week.
I let them play VR (I have a Rift and a Vive), which has proven to be non-addictive (again, not scientific, just my experience with them). But, it'snot clear whether it's good or bad for the eyes...

Our 6 year old is maybe similar to yours. He watches videos & plays roblox way more than you'd think he should be allowed to. He shows some addictive behavior (it seems like it's all he wants to do, occasional tantrums when he has to stop, talking about it all the time).
However... he's two years ahead of his peers in reading and possibly 3 in math. We try to direct his videos to "learning videos", which is at least somewhat successful (maybe 30% learning videos?).
The big thing for me is that he seems

There's.a whole lot of nuance that tends to get lost. Also depends on the kid. Mine is fit and active (unlike her old man) so that feeds into it too.

I was confused at first by what they meant by screen time because it used to mean how much time you are on TV or in a movie.
My oldest son spent a lot of time on the computer when he was in high school I bought him a C++ book called Game Gurus Guide to C++ or something like that. He made clones of all of his favorite nes games with twists and extra levels and he grew up to be a software developer.

Great. Those of us having a single parent and needing to wear glasses may be statistical outliers in the realm of no hope.

Children should be exposed to this as little as possible. They should be physically moving around, playing with other children, becoming properly socialized, honing their coordination, so on: being kids, basically, not being drones staring at one screen or another.
