Is everything Johann Hari knows about depression wrong?

The Observer has published an excerpt from Johann Hari's new book challenging what we know about depression. But do his own claims and arguments stack up?

I do not know Johann Hari. We've never crossed paths, he's done me no wrong that I'm aware of, I have no axe to grind with him or his work. And, in fairness, writing about mental health and how it's treated or perceived is always a risk. It's a major and often-debilitating issue facing a huge swathe of the population, and with many unpleasant and unhelpful stigmas attached. In recent years there have been signs that the tide is perhaps turning the right way, but a lot of work remains to be done. However, if you're going to allow an extract from your book to be published as a standalone article for mainstream media with a title as provocative as "Is everything you know about depression wrong?", you'd best make sure you have impeccable credentials and standards to back it up.

Let's address the elephant in the room: Johann Hari does not have a flawless reputation. He has been absent from the spotlight for many years following a plagiarism scandal, compounded by less-than-dignified behaviour towards his critics. Admittedly, he has since shown remorse and contrition over the whole affair, but even a cursory glance online reveals he's a long way from universal forgiveness. Logically, someone with a reputation for making false claims should be the last person making high-profile, controversial, sweeping statements about something as sensitive as mental health. And yet, here we are. It's 2018 after all.
