Wearable tech uses shock therapy to exorcise bad habits

Ivan Pavlov was a Russian physiologist famous for experiments in classical conditioning — the idea that behavior can be manipulated by associating it with positive or negative stimuli. It’s a concept that’s been embraced by productivity experts, and is key to recent success of gamification. Now Pavlok is a smart wristband that tracks owners’ behavior and delivers an electric shock when they fail to commit to their goals.
