Came here to say this. This blog was founded to convince others of the harm of smartphones. It's not unreasonable to imagine that the authors have significant confirmation bias. Everything they claim needs to be taken with a big grain of salt. Haidt is also marketing his book via the blog.

The fact he doesn't publish properly is consistent with my hunch that his claims wouldn't stand up to scientific scrutiny.
