Ask a hundred people what they block and you don't get a hundred different answers. You get the same handful of categories over and over: short-form video feeds, social media, and news apps with infinite scroll. Almost nobody blocks their calculator, their banking app, or their calendar. That pattern is worth taking seriously, because it isn't about which apps people happen to use most — it's about which apps were built to resist being put down.
The block list is a map of design intent, not personal weakness
Every app on a typical block list shares the same structural feature: no natural stopping point. A feed refreshes infinitely. A short-video app queues the next clip before you've finished deciding whether you liked the last one. There's no "end" to reach, no completion state, because completion is the one outcome the design is built to avoid. Compare that to a banking app, which has a clear task, a clear finish, and closes itself out of your attention the moment the task is done. Nobody blocks apps that let them feel finished.
Why willpower explanations get this backwards
The common framing is that some people have the discipline to use these apps in moderation and some don't. But the block-list pattern doesn't support that — it's not that undisciplined people block social media and disciplined people don't need to. It's that the apps on the list are engineered by well-resourced teams specifically to defeat moderation, for anyone, using techniques (variable reward timing, autoplay, infinite supply) borrowed directly from slot machine design. Blocking them isn't a discipline failure. It's a rational response to a system built to outlast discipline.
The apps that almost never make the list
Utility apps with a clear task and a clear end. Even genuinely time-consuming apps — a long game with defined levels, a long-form reading app — get blocked far less often, because they have natural stopping points a user can actually reach and recognize. The absence of an ending is the specific design choice that produces a block-list entry, not the app's category or its addictiveness in the abstract.
What this means practically
If you're deciding what to block, the diagnostic question isn't "do I use this too much" — it's "does this app have a natural end I can reach, or does it refresh forever." Apps without an end belong on the list regardless of how disciplined you consider yourself, because the design was never a fair fight to begin with.
