Why Marriages Succeed or Fail: And How You Can Make Yours Last

John Gottman presents a scientific analysis of marital longevity based on his observations of couples in a laboratory setting. He identifies the specific communication patterns that predict divorce, most notably the Four Horsemen: criticism, contempt, defensiveness, and stonewalling. The book argues that the presence of conflict is less important than how a couple manages it. Gottman categorizes stable marriages into three distinct styles—validating, volatile, and conflict-avoiding—and explains that maintaining a five-to-one ratio of positive to negative interactions is the primary requirement for a lasting bond.
