"Carsten used mobile-phone text-messaging to collect data on what people did during the day and how they felt about it, a technique called “experience sampling”.
Using mobile-phones to sample what people do provided information on well-being in people's everyday lives which was richer than traditional surveys.
"I texted people three times a day over a week and the response rate was really high. People are never far from their cellphones these days. People replied to on average 97 percent of all text-messages, and texts were sent at random times, so there is a really rich sample of everyday life to look at."
