the linked study effectively drills down on aspects of previous work ...

"High-frequency SFV [short form video] use was consistently associated with attentional disruption, reduced executive functioning, and emotional dysregulation."

"Neuroimaging results revealed reduced activation in the Dorsolateral Prefrontal Cortex (DLPFC) and Anterior Cingulate Cortex (ACC) regions ... when participants viewed personalised TikTok videos."

https://www.medrxiv.org/content/10.1101/2025.08.27.25334540v...

"(The ACC) is involved in ... higher-level functions, such as attention allocation, reward anticipation, decision-making, impulse control .. and emotion."

https://en.wikipedia.org/wiki/Anterior_cingulate_cortex

"The DLPFC is ... the highest cortical area that is involved in motor planning, organization and regulation."

https://en.wikipedia.org/wiki/Dorsolateral_prefrontal_cortex

by permitting unlimited short form content and not disallowing child access we are allowing corporations to destroy kids brains. therefore I posit the latest generation has been rendered retarded, which will pose a dire threat to continued stability unless addressed.

LLMs and social media is 500+ PHD behavioral psychologists working together to make you do things at any price so they can make as much money as they can - in fact, if they don't try to make as much money as they can, everyone involved will be fired.

To me this is one of the final forms of our current laissez-faire capitalism - we are literally taking away our own agency in the name of "freedom" (of capitalists to maximize returns).

very worrying study, essentially its a digital->neurochemistry chasm crossing substance that uses the 2 senses.

all more reasons to heavily discourage the usage of short form content , we might require regulations against what is essentially an invisible drug that rapidly replicate and distribute itself among the masses.

Full social media ban would be easier and more effective imo. Public spaces would come back to life in no time at all if social media was heavily curtailed or banned entirely. This would be an obvious win for everyone involved outside of the terminally online and corporations benefiting from their lack of self control.

define short form content as anything under an arbitrary time threshold, legislate all online providers of short form content to mandate an arbitrary time limit per day for all users, add a law that parents knowingly allowing children to exceed national daily short form content limits are subject to penalty. seems fairly straightforward. but uh, I guess we could all capitulate to giving corporations our biometric data ...

I don't think it's straightforward at all. What's considered "short form content".

Just video?

Does just audio count?

Does a gif count?

What if I make a website that uploads videos at 1/10th the speed, and the user plays it back 10x faster so it becomes short form?

What if i make a video aggregator website that pulls from multiple different sources so the user gets around the time limit per day per user?

What if users just make multiple accounts?

I don't think we are legally equipped to deal with this at all.

You know any time any legislature proposes anything they have dozens of people involved in months of debates and consultations and reports and committees to go through all of this kind of minutiae to decide where to draw the lines.

It's fairly obvious what "short form content" is in context of discussions around TikTok, Reels, Shorts etc.

Let me add, it sound very much like 3D-prohibition for guns. The total demonization of anything, because it could be bad, given certain conditions, is a recipe for disaster. As you say, is extremely difficult to define where are the limits, and the extremely hard to apply the limits without screwing over millions.

Don't underestimate the desire some people have to screw over millions rather than merely thousands :(

study each proposed form of short form content regarding impact on cognitive function and select the most destructive forms for legislation.

if you make a website that provides short form content you are subject. why would an aggregator be excluded?

go ahead and let users make multiple accounts. the current, invalid, answer here is biometric provisioning (done not to protect anything but government and corporate interests). personally I don't care if an adult wants to fry their brain, provided that they have been adequately educated as to the extent of what they are doing to themselves. it's why I included the parental proviso, because protection from brain frying is most important during childhood.

How about anything that tracks the user's behavior and changes its output based on that behavior specific to that user. If I have a table somewhere in my software that identifies a user and references behavior, not intentional settings, just behavior and that is used to determine what the software does. Make that illegal and a lot of problems go away. To me it is this feedback loop that is insidious.

Shocking that Zhejiang University didn't find this when TikTok was Chinese...
