Reddit's feed is infinite, algorithmically ranked, and organized around communities. The comment sections are the real time sink: threaded discussions that reward scrolling deeper.
Why this score
The home feed and subreddit feeds are infinite scroll with algorithmic ranking. Comment threads expand as you tap, creating depth-first browsing with no floor.
Upvotes and karma are public engagement metrics. Notifications for replies and upvotes create variable-reward checking habits.
The breakdown
- Attention Capture7.0
Mechanics designed to keep you in the app right now — infinite scroll, autoplay, variable rewards, and reactive swipe-tap loops.
- Habit Formation5.0
Mechanics designed to bring you back — streak coercion, default push notifications, and re-engagement of dormant users.
- Social Pressure3.0
How much the experience exploits social psychology — public metrics, profile curation, and status comparison against others.
- Time Theft7.0
Mechanics that steal more time than you intended to give — no stopping cues, short units, and 'just one more' loops.
- Cognitive Erosion1.0
Mechanics that replace your independent thinking, memory, or judgment — creating dependency on the tool to function.
- Cognitive Nourishment4.0
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 a time limit and use specific subreddits rather than the home feed.
