With every new connected device, messaging application or digital service that enters our lives - it becomes increasingly difficult to resist the seductive lure of technology on our attention. For Natasha Schull, a cultural anthropologist and associate professor in the Department of Media, Culture, and Communication at New York University, the addictive nature of devices, whether slot machines or smart phones, is no accident. In her recent book, ADDICTION BY DESIGN: Machine Gambling in Las Vegas, she explored the relationship between technology design and the experience of addiction. Her next book, KEEPING TRACK: Personal Informatics, Self-Regulation, and the Data-Driven Life concerns the rise of digital self-tracking technologies and the new modes of introspection and self-governance they engender. Meeting up in Soho, New York - we spoke about the nature of addiction and what makes the design of a particular technology so enthralling, the strange trance-like states that gamblers experience, the quantification of work and life, and why smartphones are a kind of ‘Skinner box’.
