TikTok
TikTok's feed plays short videos one after another with no end point. The algorithm adjusts in real time to what holds your attention. Most users stay significantly longer than they planned to.
Why this score
The feed never stops. Videos autoplay, each one under 60 seconds, so you never have to commit to watching something long. Notifications are on by default and the app sends re-engagement alerts when you haven't opened it.
There's no session timer, no 'you've been here a while' prompt, and no natural place to stop. Almost nothing in the default design asks you to think, create, or decide.
The breakdown
- Attention Capture10.0
Mechanics designed to keep you in the app right now — infinite scroll, autoplay, variable rewards, and reactive swipe-tap loops.
- Habit Formation7.0
Mechanics designed to bring you back — streak coercion, default push notifications, and re-engagement of dormant users.
- Social Pressure7.0
How much the experience exploits social psychology — public metrics, profile curation, and status comparison against others.
- Time Theft10.0
Mechanics that steal more time than you intended to give — no stopping cues, short units, and 'just one more' loops.
- Cognitive Erosion2.0
Mechanics that replace your independent thinking, memory, or judgment — creating dependency on the tool to function.
- Cognitive Nourishment1.0
Whether the app actively strengthens your ability to think for yourself. Shown on the label, but it does not affect the score.
Recommended usage
Set your own timer before opening. The app won't remind you to stop.
