Smartphones and our information overload

The internet, and the ever-present smartphones from which we cannot detach ourselves, are changing the ways we relate to technology - and, at the same time, changing the way we use our brains. Senior Contributor Ted Koppel talks with technology critic Nicholas Carr, software developer Justin Rosenstein, “media psychologist” Byron Reeves, and Sen. Mark Warner about how the internet and social media have become weaponized, and how it is our attention spans that are being targeted.

How social media makes adolescence even harder

The new dramedy "Eighth Grade," about a painfully shy 13-year old stumbling through her last week of middle school, is the first film for writer-director Bo Burnham and for its young star, Elsie Fisher. But there's more to the movie than the usual teen angst and acne. There's the loneliness that, research tells us, is becoming more pervasive for young people as social media increases in influence. Tracy Smith talks with Burnham, and with San Diego State professor Jean Twenge, author of "iGen," about how the internet is making adolescence even tougher.

Going it alone

According to a recent study, nearly half of Americans now say they sometimes or always feel alone, and one in five says they rarely or never feel close to anyone. And researchers say that the more social media we use, the lonelier we are likely to be. Susan Spencer talks with John Francis (a man who talked to no one for 17 years), and with doctors who say loneliness can lead to increased mortality equal to smoking 15 cigarettes a day. She also meets with the founder of the "Sidewalk Talk" community listening project, where people are invited to speak out to perfect strangers.
