Put the phone down. Finish a clearer sentence.

A feed will always have a next thing. Your nervous system will always have a next worry. Stack them and an hour disappears into other people’s emergencies, quizzes about your personality, and a joke you will not remember tomorrow.

We would rather you leave with a clearer sentence about your own brain. That is the whole project, said without a brochure: accessible, a little fun, easy enough to finish. Psychology you can actually use — then go outside, or at least look up.

It is not a fair fight, and that is the point

NIMH notes that the prefrontal cortex — ranking, braking, choosing — is among the last regions to finish, stretching into the mid-to-late twenties. A designed infinite scroll is aimed at a planning system still under construction. Getting pulled in is not a character flaw. It is a product working as designed.

The teen brain is also tuned to peers. A like, a read receipt, a headline about someone like you: social alarms feel like information. Sometimes they are. Often they are bait.

A smaller door than “never use your phone”

Put it face-down for the length of one explainer. Write one sentence you could send a friend. Then you can go back. The point is not a brand of abstinence. The point is interrupting a spiral with something true and short.

If what you are scrolling is self-harm content, or you feel unsafe, close the app and use 988 or talk to a person in the room. A clearer sentence includes “I need help now.”
