A Strange Phenomenon: What Pigeons Teach Us About Phone Addiction

Scientists have observed a strange behavior in animals, such as pigeons, raccoons, and rats, where they focus on the signal of a reward (such as a light indicating food) rather than seeking the reward itself. This behavior, called “sign tracking,” appears to explain people’s obsession with smartphones. In experiments with pigeons, the birds began to pay more attention to the light that signaled food than to the food itself, missing the opportunity to eat. This phenomenon is paralleled by how people interact with their phones, focusing on notifications and signals (such as app icons, red dots) instead of seeking their actual needs. Smartphones and apps offer a constant stream of signals that suggest the possibility of social interaction or gratification, creating a sense of craving and desire. These signals exploit the human need for social connection, similar to the need for food, water, and safety. This study highlights how technology can “trick” us into not focusing on what we really need, but constantly chasing the signals that indicate the possibility of gratification. Understanding this phenomenon can help develop more mindful relationships with technology.
