Episode 34: Does depression exist?

Several previous episodes of The Studies Show have covered depression and treatments for it, but none have really considered what depression is. It’s time to do that. It turns out that some scientists have made serious critiques of the standard way of thinking about depression, and argue that we need a revolution in the way we measure it.In this episode of The Studies Show, Tom and Stuart take nothing for granted - they look into the idea of “latent variables”, read the studies critiquing the concept of a single, monolithic “depression”, and talk about what this all means for how we treat people with these often-terrible symptoms.We’re proud to be sponsored by Works in Progress magazine, which is, as they put it, “a magazine of new and underrated ideas to improve the world”.
