Could this be why social media appeals so much?
Neuroeconomist Paul Zak has discovered, for the first time, that social networking triggers the release of the generosity-trust chemical in our brains.
The essence of affection. The cuddle chemical. In other words, oxytocin.
In a series of studies spanning nine years, Zak has changed our understanding of human beings as economic animals. Oxytocin is the key (and please, do not confuse the cuddle drug with the painkiller oxycontin). Known for years as the hormone forging the unshakable bond between mothers and their babies, oxytocin is now, thanks largely to Zak, recognized as the human stimulant of empathy, generosity, trust, and more. It is, Zak says, the “social glue” that adheres families, communities, and societies, and as such, acts as an “economic lubricant” that enables us to engage in all sorts of transactions.
So maybe young peopls obsession with social media is just a way of getting an on-line cuddle
