A while back, The Studies Show covered the question of whether smartphones and social media cause mental health problems. Amazingly, that podcast didn’t settle the issue, and the debate has continued—and continued rather acrimoniously.

Psychologists—most notably Jonathan Haidt—are currently laying into each other, analysing, re-analysing, and meta-analysing datasets to try and work out whether “it’s the phones”. In this paid-only episode of The Studies Show, Tom and Stuart explain the story so far, and in the process get very disappointed by their heroes.
