“By the time a couple’s style of argument has escalated into shaming and blaming each other, the fundamental purpose of their quarrels has shifted. It is no longer an effort to solve a problem or even to get the other person to modify his or her behavior; it’s just to wound, to insult, to score. That is why shaming leads to fierce, renewed efforts at self-justification, a refusal to compromise, and the most destructive emotion a relationship can evoke: contempt. In his groundbreaking study of more than seven hundred couples whom he followed over a period of years, psychologist John Gottman found that contempt—criticism laced with sarcasm, name calling, and mockery—is one of the strongest signs that a relationship is in free fall.”
