I used to think so too, but I've met people smarter than I am who legit binge watch cute puppy videos for a basal emotional high they enjoy, just like a lot of other people can't help but impulsively wanna see a volleyball athlete's crotch. It's junk food; people are programmed to love it regardless of intelligence.

It seems plausible that there is at least a moderate correlation between low IQ and watching these videos.
