His second point in his rebuttal is particularly eyebrow raising.

Do you mean this one?

Odgers’ alternative explanation does not fit the available facts.

Because that's obviously correct. I don't know where you live, but I live in continental Europe, where issues such as "opioid crisis, school shootings and increasing unrest because of racial and sexual discrimination and violence" simply do not exist or are, at worst, not increasing. (One exception might be a very specific variant of opioids, which is gambling. Edit: Besides, gambling is also heavily promoted online, made easier to access, even packaged into video games, so it's just a further problem for defending phone-/internet-centric teenage culture.) They also frequently have little to do with how young people feel, think and live in general even in US, as far as I see from the stuff (conversations, media) that I see online. Projecting these very specific issues onto all young people all across the world looks like nothing more than American defaultism.

I've read both the review and the response, and I find the response more convincing, supported by much more explicit data and clear arguments.
