Not long ago, the tendency to think of people, things and ideas as either all good or all bad was considered a weakness. Black-and-white thinking, also called “splitting,” was widely viewed by mental health professionals as dysfunctional and maladaptive. It was a necessary feature for a diagnosis of borderline personality disorder. That diagnosis is mostly out of fashion today. Unsurprisingly, so is the view that splitting is either maladaptive or dysfunctional.
