That appears to be a quickly referenced theory by one (yes qualified) person on one blog post without a study behind it. I could also argue that kids generally have short attention spans but social media just allows them to indulge in it more, and they will of course prioritize attention to that over other things. That is not the same as “it shortens their attention spans.” We need at least one study here or at least something more substantive than a one-liner linking social media and decreasing ones attention span. I’m not sure if you noticed, but blog is actually focusing on how to reach kids and strategies to get them to pay attention. It has one throw away non-cited line about social media shortening attention spans.

I should also point out that I also did a cursory Google search before writing the previous comment, and that was the only post I saw as well. The reason you selected it is because there was no other decent hit when you searched I imagine.

Let me be clear here, the only reason I am sort of arguing about this is because there is a really bad propensity for older people to say something is wrong with younger people. We see it over and over again. I think social media is actually very harmful to kids, but I have yet to see anything that shows it actually diminishes ones attention span. And the reason I really don’t like that claim is because it seems to be just another variation of “kids these days.”
