UnHerd's Freddie Sayers talks to John Burn-Murdoch, the chief data reporter for the Financial Times, as well as Hernan Moscoso-Boedo and Nathan Hudson from the University of Cincinnati, to investigate a controversial new study suggesting that the global proliferation of smartphones and social media since 2007 has drastically altered young people's behaviour, halved face-to-face socialisation, and accelerated a worldwide collapse in fertility rates that cannot simply be explained by the global financial crisis.
