Research on the long-term impacts of short-form video consumption is still lacking, but recent studies show concerning associations with cognition and mental health.

With short-form video now dominant on social media, researchers are racing to understand how the highly engaging, algorithm-driven format may be reshaping the brain.

From TikTok to Instagram Reels and YouTube Shorts, short-form video content has become a cornerstone of just about every online platform, including LinkedIn and even Substack. But increasingly, studies are finding associations between heavy consumption of short-form video and challenges with focus and self-control.

The research, though still early, seems to echo widespread concerns over “brain rot,” an internet slang term that the Oxford University Press defines as “the supposed deterioration of a person’s mental or intellectual state.” (The term became so mainstream that the academic publishing house crowned it as its 2024 word of the year.)

I avoided shorts on YT religiously, but as people sent them to me and they became more tuned to my preferences, I began absent mindedly scrolling them. I fucking hated it, I would realize I had wasted so much time idly swiping. I started running revanced specifically to turn that shit off on my phone so that the temptation wouldn't exist. So happy with my decision. I don't think it rotted my brain, but it made my phone a landmine for shit content, scammy ads, and wasted time.

    I sometimes get sent/click on shorts too, however I absolutely cannot stand that YT shorts auto-repeat, which keeps me from watching more than one video at a time (hit that back button at light speed). Plus the clickbait videos are almost always disappointing ("I tuned in for 90 seconds for something that could have been summed up in a sentence and ended up being a total dud anyway!?").

    Short form videos are fucking digital opium. I hate it. I deliberately do not have instagram/YT/tiktok accounts with the intention of avoiding it, but I have repeatedly found myself watching a short vid sent from a friend before I find myself scrolling and then snapping back to attention, 40+ minutes later, like some Jekyl/Hyde shit. I imagine it’s what having an epileptic seizure is like. I just lose track of time completely and I hate it.

    I never agreed with Bradbury about how TV is so bad so forth, but I am with him now. Shit’s addictive

    Luckily for me there are so many commercials in Tiktok now that I tire of it quickly. What's been happening lately is Tiktok sends me to YouTube because someone chopped up a 30 minute YouTube video into 7 parts to make more money than 3. It's harder to discover content on youtube for me.

    The issue isn't the short form video. It's the algorithm behind everything to keep people addicted to what ever social media website.

    Short form video (and it's sibling, the infinite headline scrollers) are the final evolution of engagement architecture. There's nothing inherently nefarious about an algorithm presenting content, but these platforms fracture the content into a bottomless feed of tiny dopamine doses, requiring some smart behavior to present all of that.

    I'd argue that a short form video platform couldn't exist without a finely tuned algorithm. With long form videos the barrier to creation limits the pool of available content. A smaller and deeper pool is more manageable for manual curation. A wider and shallower pool is exponentially harder:

    • Just navigating each video (even a <1s interaction) adds a large overhead to consuming the content. This could be 16% of your time watching 6s vines.
    • You basically have to watch most of the clip to judge it's quality. Even a 3s glance could put a hard floor of watching 5-10% of all content.
    • The amount of video topics in short form dilutes high quality creators. Is it likely that a creator who covers 3 topics in interesting, in-depth 30 minute videos could match that engaging runtime with 90+ diverse topics?

    Take out a content distilling/targeting algorithm and your platform is unusable.

    challenges with focus and self-control

    This seems to be what teachers are reporting.

    There's some threads in /r/teachers on that other site which are pretty terrifying. It sounds like the majority of kids are in dopamine withdrawal all day at school.

    "TV will rot your brain."

    Well yeah but just because "they" no longer say that doesn't mean it isn't true, nor does it mean that short form video doesn't "rot your brain".

    As in all things, moderation is key.

    If you let your kids watch this trash for hours a day they're going to be imbeciles.

    What do you get from a glut of TV?
    A pain in the neck and an IQ of 3!
    Why don't you try simply reading a book?
    You'll get no.... commercials....!

    While I admire the "modern" remake movie for sticking closer to the book on the characters caricatures, the Gene Wilder version of this movie is still great in its own way. Particularly the oompa loompa songs.

    Yeah. This feels like people finding what they want to find. This is a meta analysis are not useful, at best it's an indication there is a potential for a targeted study.

    Everytime I've dug around these "smart phones are the end of the world" type of studies, I can find null hypothesis studies that used more controls.

    Obligatory Carl Sagan from 1995:

    I have a foreboding of an America in my children's or grandchildren's time -- when the United States is a service and information economy; when nearly all the manufacturing industries have slipped away to other countries; when awesome technological powers are in the hands of a very few, and no one representing the public interest can even grasp the issues; when the people have lost the ability to set their own agendas or knowledgeably question those in authority; when, clutching our crystals and nervously consulting our horoscopes, our critical faculties in decline, unable to distinguish between what feels good and what's true, we slide, almost without noticing, back into superstition and darkness...

    The dumbing down of American is most evident in the slow decay of substantive content in the enormously influential media, the 30 second sound bites (now down to 10 seconds or less), lowest common denominator programming, credulous presentations on pseudoscience and superstition, but especially a kind of celebration of ignorance

    As someone who fought against the idea of just getting outside for years I've started doing more outside activities and I find that it helps alot more than I wish to admit.

    Maybe that's because I'm doing it all stoned outta my gourd though?

    Gatekeep at the grocery store. It's easier to resist eating a full tub of Oreos by deciding not to buy them in the first place

    It's easier to moderate what platforms you use than it is to resist their affect on you. Restrict where and how you are exposed to short form video and what kinds of social media you use

    Also, take magnesium glycinate, but not on an empty stomach. Basically everyone with ADHD has a magnesium deficiency that makes the symptoms way worse
