CBT can work, sure. It can also not work. As with any treatment. And depression is only one mental illness, there are countless others. And there are also many different forms and causes of even depression itself. As I mentioned in another comment, my point isn't that the article's advice is necessarily harmful, just that it oversimplifies a lot of things by assuming that all psychology can be boiled down to learning and unlearning. Ignoring the role of biology may also cause one to ignore possible paths to progress.
