No, I did not mean I wanted evidence of their effect on kids. I want evidence that "putting your kid in a room full of $bad_stuff" always leads to addiction, since that strikes me as nothing more than scare stories.

Good parents can raise their children correctly even with $bad_stuff present around them, that was the point I was trying to make.

I concur. But the internet exposure of kids is mostly not governed by parents. They either are alone with the connected device in their rooms, away from them, or with a mobile device out of their home. The best the parents can do is to educate the kids, but the public lacks the knowledge to effectively do so. They should be given the formation to be able to educate their children, and furthermore schools should educate minors on the use of tech.

"putting your kid in a room full of $bad_stuff" will mostly lead to addiction if the parent is not there to teach the kid: this is harmful to you; not you think?

Mostly agreed, yes. But I would rephrase it as "introducing kids to $bad_stuff without guidance is a bad idea": I don't think that permanent supervision should be required. Once the novelty wears off, and the parent is confident that the kid can behave themselves even in the presence of $bad_stuff, even "putting your kid in a room full of $bad_stuff" can be fine.

And I don't mean that in the sense of "the kids are fine with their heroin syringes", but in the sense "I can leave the cookie jar on the counter and it will still be there when I leave the room".
