"the results were the same regardless of whether the children published posts and pictures via their own social media pages or whether they liked and commented on posts published by others." - so basically the study compared people that use social media actively and passively. It's harder to compare children that use social media with the ones that don't.

It seems to me that building expectations based on social media (e.g. just by browsing) is the real problem, not posting or not.
