Most people have done it at least once. They open a social media app, search for a specific person's profile, scroll through recent posts, examine who liked the photos, and then promise themselves they are done. A few hours later, they check again.
On the surface, this behavior looks like curiosity. Psychology suggests something deeper may be happening. Repeatedly checking someone's profile is often less about gathering information and more about satisfying emotional needs that the brain has not fully resolved.
