Welcome to the third and final post examining the idea that one in four of us suffer mental illness at some point in our lives.
As I explained in parts 1 and 2, "one in four" has no basis in the scientific literature, although given how dubious the literature is, this is not necessarily a bad thing. It's not clear where the one in four meme originally came from, although most of the recent uses probably trace back to a 2001 WHO report which quoted it.
