Parents do not have to be "experts in chilhood development" to know what is best for their children. Especially experts in their fields like the manufacturing of alcohol, guns or other products universallly considered dangerous.

So, if parents can rely on a a century of more of science showing the negative impacts of guns, tobacco, and alcohol on children… they can rely on vibes and politicians for evidence of harm from screens?

I’m not even arguing with you. I’m just disappointed in how quickly so many on HN throw out all pretense of being interested in data as soon as a personal hot button issue comes up. It’s human nature I guess, but still depressing.

Screens are harmful for adults too. Everyone knows this through the personal experience of doomscrolling hours of one's own life away. Why would they be any better for children?

Or do you imagine that there's a study out there that will reveal that arguing on Twitter with someone called Catturd2 is good for your mental health?

You feel pain? Doctor says it's probably in your head because statistically you shouldn't. -- Based on countless true stories.

Data is map, not terrain. It can explain some of the quantifiable world, not all of it. Common sense can also fill some of the gaps, some of the time. And there remains plenty still that's too entropic for our grasp. Waiting for data to speak is not always the best move. Heck, it might even sometimes be the worst. It seems this is a lesson we collectively keep forgetting over and over, despite the endless list of data-backed "facts" that, in hindsight, it turns out we were wrong or short-sighted about. Apparently, that too is human nature.

The existence of science does not obligate us to either receive a double-blind study of massive statistical significance on the exact question we're thinking about or to throw our hands up in total ignorance and sit in a corner crying about the lack of a scientific study.

It is perfectly rational to rely on experience for what screens do to children when that's all we have. You operate on that standard all the time. I know that, because you have no choice. There are plenty of choices you must make without a "data" to back you up on.

Moreover, there is plenty of data on this topic and if there is any study out there that even remotely supports the idea that it's all just hunky-dory for kids to be exposed to arbitrary amounts of "screen time" and parents are just silly for being worried about what it may be doing to their children, I sure haven't seen it go by. (I don't love the vagueness of the term "screen time" but for this discussion it'll do... anyone who wants to complain about it in a reply be my guest but be aware I don't really like it either.)

"Politicians" didn't even begin to enter into my decisions and I doubt it did for very many people either. This is one of the cases where the politicians are just jumping in front of an existing parade and claiming to be the leaders. But they aren't, and the parade isn't following them.

You need science to realise that guns are a danger to kids?

[brookst]

No, but I believe that science and quantifying the specific danger leads to better policies than going on vibes. For instance, laws to require safe storage are based on data quantifying reductions in harm to children [1]

Data beats vibes, even when vibes are qualitatively correct. I’m surprised this is surprising.
