Hooked: How to Build Habit-Forming Products

by Nir Eyal

Who is your product’s user? What is the user doing right before your intended habit? Come up with three internal triggers that could cue your user to action. Refer to the 5 Whys Method described in this chapter. Which internal trigger does your user experience most frequently? Finish this brief narrative using the most frequent internal trigger and the habit you are designing: “Every time the user (internal trigger), he/she (first action of intended habit).” Refer back to the question about what the user is doing right before the first action of the habit. What might be places and times to send an external trigger? How can you couple an external trigger as closely as possible to when the user’s internal trigger fires? Think of at least three conventional ways to trigger your user with current technology (e-mails, notifications, text messages, etc.). Then stretch yourself to come up with at least three crazy or currently impossible ideas for ways to trigger your user (wearable computers, biometric sensors, carrier pigeons, etc.). You could find that your crazy ideas spur some new approaches that may not be so nutty after all. In a few years new technologies will create all sorts of currently unimaginable triggering opportunities.
