What are the "four horsemen" that predict relationship breakdown?

They are four communication patterns identified by psychologist John Gottman, whose research observed couples discussing conflict and tracked which relationships lasted. The four were found to be strong predictors of separation — hence the biblical nickname.

Criticism. Attacking the person rather than raising the behaviour. "You never think about anyone but yourself" instead of "I felt ignored when you made plans without asking me." The distinction is between a complaint, which is about an event, and criticism, which is a verdict on character.

Contempt. Treating a partner with disdain — mockery, sarcasm, eye-rolling, name-calling, a superior tone. Gottman identified this as the single strongest predictor of separation. It communicates not just disagreement but disgust, and it is corrosive because it forecloses the possibility of being persuaded.

Defensiveness. Meeting a complaint with counter-attack, excuses, or innocent victimhood. It is usually a response to feeling criticised, and it reliably escalates because it tells the other person their concern will not be heard.

Stonewalling. Withdrawing entirely — going silent, disengaging, leaving the room. It is often a response to physiological overwhelm rather than indifference, which matters because the intent and the effect differ sharply.

The proposed antidotes: raise complaints about specific behaviour rather than character; build a habit of appreciation, which is the practical counter to contempt; take responsibility for some part of the problem rather than defending; and for stonewalling, name the need for a break and set a time to return, since leaving without explanation reads as abandonment.

Two caveats worth stating. Some of Gottman's headline prediction accuracy figures have been criticised for being derived and tested on overlapping data. And the presence of these patterns describes a dynamic to work on — it is not a verdict on any particular relationship.
