The happiness effect: how social media is driving a generation to appear perfect at any cost

Sexting. Cyberbullying. Narcissism. People - and especially the media - are consumed by fears about the effect of social media on young people.

We hear constantly about the dangers that lurk online, and about young people's seemingly pathological desire to share anything and everything about themselves with the entire world.

Donna Freitas has travelled the country, talking to college students about what's really happening on social media.
