Even though everybody seems convinced our attention spans have decreased, there is no conclusive evidence of it and scientists don’t even really think it is useful to talk about attention outside the context of motivation anyways.

Your attention span is fine, you are just too burned out from modern life to invest energy into things that take a lot of sustained focus that aren’t essential to survival.

You also have to be way more picky with what content you choose to engage with because there is sooooooo much more content now and that may look like a “short attention span” when your brain optimizes for tossing out the 95% off fluff to get right to the thing you actually wanted.

Our attention spans are fine, this has been the most boring moral panic ever but that is really all it is.

Shortened attention span falls under mental well-being.

The older generation has always criticized the younger generation for the same things. And yet again it is done without merit.

This isn't a study, it's a book review refuting the author's assertion. But it looks like the scope was only mental health, not cognitive skill.
