Unlimited skipping until a video is sufficiently stimulating had a negative impact regardless of the content, while people limited to ten skips in ten minutes did not experience a negative impact. This suggests that the format itself has harmful cognitive effects.
As an example: there's this stupid skit going around. Someone asks a waiter "Could I ask you about the menu please?". The waiter comes really close and goes like "The men I please is none of your business".
It's an ok joke but I've seen literally 20 different people doing the same skit in the last two weeks and it gets so damn annoying. And it's not just this one. There's always one that is viral and everyone copies it.
congratulations on discovering mimesis
edit: which is to say I'm not positive the format isn't the problem.
Those aren't the kinds of book-related videos that I see, so at some point The Algorithm must've decided I wasn't interested in porn for women (not that there's anything wrong with that).
