Why short-form feeds are so hard to put down

There is a familiar experience with short-form video. You finish a video. The next one starts. Then another. And another.

There is almost no physical or cognitive effort required to continue. That design matters.

The disappearing stopping point

Traditional media often contains natural stopping points. Short-form feeds can remove them. Instead of asking: "Do I want to watch another video?", the interface effectively answers the question for you. There is already another video waiting.

That doesn't prove that infinite scrolling is inherently harmful. But it changes the decision environment. Research into digital wellbeing has increasingly examined how interface design, engagement mechanisms, and patterns of use interact with users' attention and wellbeing. PubMed Citation ↗

The dopamine explanation is incomplete

"Dopamine" has become shorthand for almost everything people dislike about social media. That's too simple.

Dopamine is involved in many functions, including motivation, learning, and reward prediction. It isn't a chemical that simply switches addiction on when someone opens TikTok or Instagram. The more useful question is behavioral: What keeps making the next action easy?

Short-form feeds combine several elements:

• Continuous content
• Personalized recommendations
• Rapid feedback
• Novelty
• Social signals
• Very low effort between items
• No obvious endpoint

Each individual feature is relatively ordinary. Together, they create a very efficient consumption loop.

What recent evidence suggests

A 2026 systematic review examined 42 studies involving 46,912 young people and found that heavy, unstructured short-form-video use was consistently associated with several cognitive and emotional outcomes, including inattention, impulsivity, anxiety, depression, stress and addiction symptoms.

But there is an important limitation: 88% of the included studies were cross-sectional, meaning most could identify associations but could not establish causation. The review itself called for more longitudinal and experimental research. PubMed Citation ↗

That's the kind of nuance that gets lost online. The evidence is concerning. It is not the same thing as proving that watching Shorts causes every negative outcome associated with it.

The design question & the Dedoom approach

The more interesting question for digital wellbeing isn't: "Are short videos bad?" It's: "How much control does the user have over when the consumption ends?"

That's where selective intervention becomes interesting. If someone needs YouTube for a lecture, completely blocking YouTube doesn't solve the actual problem. The distraction may be one specific surface inside the platform.

Dedoom treats that distinction as important. You can use YouTube. You can search. You can watch long-form content. You can learn. But if Shorts are the part that repeatedly pulls you into an unintended session, Dedoom can hide that surface instead.
