# Is Short-Form Video Really Hurting Your Attention Span?

TLDR

A review of 70 studies and nearly 100,000 people found that heavier short-form video use travels with weaker attention and weaker impulse control. The catch: it is all correlation, so no one has shown which way the arrow points. The steady read sits between the panic and the shrug.

A maker I work with finishes something hard, leans back for the ten seconds before the next task, and her thumb is already on her phone. A short video is autoplaying before she chose to watch anything. She is not weak, and that gap is not an accident. It is engineered. Every few weeks a headline lands saying gaps like that are quietly shrinking everyone’s attention span. This week I went and read the largest study sitting under that headline.

## What a 98,000-Person Review Actually Found

A research team led by Lan Nguyen pooled 70 studies in one of psychology’s main review journals, covering close to 100,000 people. They asked a plain question: what travels with heavy use of short-form video, the fast vertical clips that play one after another without asking. The two strongest links were not the dramatic ones. They were attention and something researchers call inhibitory control, which is the quiet brake that keeps us from acting on every small pull to switch. Heavier use tracked with weaker scores on both.

people pooled across 70 studies, making the association robust even though its cause is unknown

> "Increased short-form video use was associated with poorer cognition (moderate mean effect size, r = -.34), with attention (r = -.38) and inhibitory control (r = -.41) yielding the strongest associations."

Psychological Bulletin, December 2025

Those feeds are tuned by recommendation systems built to serve the next clip before the last one ends, which is the AI part of this story, and it is very good at its job. If that pull feels familiar, it is the same reach we looked at in the research on disliking boredom, where people fill the empty moment faster than they notice doing it. It is a close cousin of an unanswered notification that hijacks attention in the middle of a task. The same review also found smaller links to stress and to anxiety. That is a separate and more tangled question, so I am setting it aside here.

## What the Review Cannot Tell You Yet

Here is the part the scary headlines skip. Every study in this pile is correlational. It can show that heavy scrolling and weaker focus show up together. It cannot show that one caused the other. The authors say so directly, and they raise the obvious flip side: people who already struggle to hold their focus may reach for short video more, as a way to cope, rather than the video being the thing that wore the focus down. The measured effects were moderate, not catastrophic. And this review came out late last year, which makes it the most thorough look we have, not this morning’s news.

Key Insight

The real finding is not that short video shrinks your attention span. It is that the two travel together, and no one has yet shown which way the arrow runs.

## The Drift to Your Phone Between Tasks

Tomorrow, watch for one small moment. The gap between finishing a thing and starting the next, where the hand drifts to the phone before anything was decided. That drift is the brake we talked about, engaging or not engaging, in real time. There is nothing to fix in that one moment. The practice is just to see it. Then notice whether the same pull to switch turns up inside focused work, the slow uninterrupted kind where the real returns show up. The research cannot say what to do with any of this. It can only suggest the pull is worth seeing clearly. Correlation is not fate. A thing you can watch is a thing you can sit beside.
