At a restaurant around the corner from Unplug SF, Harris demonstrated an alternative way of interacting with WMDs, based on his own self-defense tactics. Certain tips were intuitive: He’s “almost militaristic about turning off notifications” on his iPhone, and he set a custom vibration pattern for text messages, so he can feel the difference between an automated alert and a human’s words. Other tips drew on Harris’s study of psychology. Since merely glimpsing an app’s icon will “trigger this whole set of sensations and thoughts,” he pruned the first screen of his phone to include only apps, such as Uber and Google Maps, that perform a single function and thus run a low risk of “bottomless bowl–ing.” He tried to make his phone look minimalist: Taking a cue from a Google experiment that cut employees’ M&M snacking by moving the candy from clear to opaque containers, he buried colorful icons—along with time-sucking apps like Gmail and WhatsApp—inside folders on the second page of his iPhone. As a result, that screen was practically grayscale. Harris launches apps by using what he calls the phone’s “consciousness filter”—typing Instagram, say, into its search bar—which reduces impulsive tapping. For similar reasons, Harris keeps a Post-it on his laptop with this instruction: “Do not open without intention.”
