In Part 1 of this mini-series looking at Jonathan Haidt's book The Anxious Generation, we discovered that the teen mental health crisis might not be as dramatic as The Anxious Generation claims - and that changes in diagnosis and coding could be inflating the numbers. But even if we accept that teens' struggles have increased somewhat, the next crucial question is: what's actually causing the change?
Jonathan Haidt is adamant that social media causes depression and anxiety in teenagers. He claims that "dozens of experiments" prove social media use is a CAUSE, not just a correlate, of mental health problems. But when you dig into the studies, as we do in this episode, we'll see that the 'causal' data is nowhere near as strong as Haidt claims.
We'll examine the experimental evidence behind social media and teen mental health claims, reveal why leading researchers compare social media effects on teens to eating potatoes, and uncover what factors actually explain 99% of youth mental health outcomes. Because if we're going to spend time and energy helping our kids, we want to make sure we're spending it doing things that will actually help.
Does social media really cause teen depression and anxiety? Research shows correlation, not proven causation, with social media effects on teens explaining less than 1% of wellbeing, similar to the effect of eating potatoes. (Some researchers argue that this is still important enough to pay attention to - the episode explores why.)
Why do I keep hearing that social media is harmful if the research is weak? Many (but not all) social media studies find some evidence of harm, but when you look at the methodology this isn't surprising - researchers do things like sending participants daily reminders that "limiting social media is good for you," and then asking them how much social media they've consumed and how they feel. It's hard to draw strong conclusions from this data!
How can different studies on social media show opposite results? Researchers studying teen social media use can get completely different results from the same data depending on how they choose to analyze it. The episode looks at those choices and what they mean for understanding whether social media causes kids' depression and anxiety.
Is limiting my teen's social media use actually going to help them? Current evidence suggests that some kids who use social media a lot are vulnerable to experiencing depression and anxiety, and limiting their use specifically may be protective. There is little evidence to support the idea that blanket bans on kids' social media/smart phone usage will result in dramatic improvements in youth mental health, and focusing on issues that are more clearly connected to mental health would likely have a greater positive impact.
