“Consider the Clocky, an alarm clock invented by an MIT student, Gauri Nanda. It’s no ordinary alarm clock—it has wheels. You set it at night, and in the morning when the alarm goes off, it rolls off your nightstand and scurries around the room, forcing you to chase it down. Picture the scene: You’re crawling around the bedroom in your underwear, stalking and cursing a runaway clock. Clocky ensures that you won’t snooze-button your way to disaster. And apparently that’s a common fear, since about 35,000 units were purchased, at $50 each, in Clocky’s first two years on the market (despite minimal marketing). The success of this invention reveals a lot about human psychology. What it shows, fundamentally, is that we are schizophrenic. Part of us—our rational side—wants to get up at 5:45 a.m., allowing ourselves plenty of time for a quick jog before we leave for the office. The other part of us—the emotional side—wakes up in the darkness of the early morning, snoozing inside a warm cocoon of sheets and blankets, and wants nothing in the world so much as a few more minutes of sleep. If, like us, your emotional side tends to win these internal debates, then you might be a potential Clocky customer. The beauty of the device is that it allows your rational side to outsmart your emotional side.”
