Thousands of psychiatrists will descend on San Francisco this weekend for a meeting that will mark the release of the latest edition of the profession’s diagnostic guide, the Diagnostic and Statistical Manual of Mental Disorders, or DSM for short. This hugely influential book has been 14 years in the making, and it’s been dogged by controversies every step of the way.

To name just a few, there have been allegations of financial conflicts of interest, debates over whether internet addiction is really a thing (it is not, but “disordered gambling” is), arguments that the new diagnostic criteria will medicalize normal grief and temper tantrums, and lead to millions of people being falsely diagnosed with mental disorders.
