After studying thousands of couples, they landed on four patterns—criticism, defensiveness, contempt, stonewalling—that showed up consistently before relationships fell apart. They could identify which relationships were heading for collapse with striking accuracy, sometimes from a single observed conversation.
The research was built on marriages. But the psychological mechanics transfer. Both relationships involve high stakes, shared accountability, and the ongoing requirement to work through disagreement with........
