We are a social-network generation. When I was thirteen we had Bebo and MSN, then it all moved to Facebook. Now we have collectively entered the nascent Instagram era. While Instagram may seem like a picturesque, sepia-tinted way to document our lives, our growing fondness for the app arguably says some very disconcerting things about our 'sharing' habits.
This 'friendship paradox' was the surprising result of a 1991 study into the properties of social networks. Sociologists have since seen this in evidence in a wide variety of situations. On average, whether it's Facebook, Twitter or sexual partners your friends, followers or partners all have (or have had) more friends, followers or partners than you.
