More therapy became available everywhere and depression rates never fell

Since the 1980s, treatment for major depression has become far more widely available across the Western world, and by most measures, far more sophisticated. Cognitive behavioral therapy matured. New generations of antidepressants reached pharmacy shelves. Insurance coverage expanded. Medicine offers a template for what should happen next: as treatment for breast cancer improved after 1989, death rates from it fell. As antibiotics became widely available, maternal deaths in childbirth collapsed. Better dental care meant fewer Americans lost their teeth.

So a group of academic researchers checked whether the same pattern held for depression. They published their findings under a blunt title: "More Treatment but No Less Depression: The Treatment-Prevalence Paradox." Their conclusion was stark. Increased availability of effective treatment should have shortened depressive episodes, reduced relapses, and lowered the overall rate of depression in the population. "Have these reductions occurred?" they asked. "The empirical answer clearly is NO." In not one Western country studied did expanded treatment reduce the prevalence of major depressive disorder. In several, prevalence rose. When Abigail Shrier followed up directly with some of the paper's authors, two told her the same pattern likely held for anxiety.

This is a paradox, not a proof. The correlation between more treatment and no less illness doesn't establish that treatment causes the problem; the authors themselves note there was probably more undiagnosed depression in the past than anyone realized. But the coincidence is hard to wave away entirely. Adolescent mental health, by multiple measures, has been declining steadily since the 1950s. Between 1990 and 2007, before any teenager owned a smartphone, the number of children classified as mentally ill rose thirty-five-fold. Something was already going wrong well before the usual list of suspects, smartphones, lockdowns, climate change, arrived on the scene.

What the paradox offers, at minimum, is a reason to stop assuming that more mental health infrastructure is automatically the fix. If pouring in more treatment, more diagnosis, and more awareness for seventy-five years hasn't dented the numbers, the honest next question isn't how do we scale this further. It's what if some of what we're scaling is part of the problem.

The next time someone tells you that the fix for rising anxiety or depression is simply more screening, more awareness, or more access to treatment, pause and ask for evidence that this approach has actually worked somewhere before, rather than just detected more cases. Learn to tell the difference between a diagnosis rate that reflects real, previously missed suffering and one that reflects an ordinary population being relabeled as sick. And when you or someone you love seems to improve after starting treatment, resist crediting the treatment automatically. Ask what else changed at the same time, more sleep, a repaired friendship, a new routine, since that might deserve the credit instead.
