The Gottman 5:1 ratio, explained

The Gottman 5:1 ratio is the “magic ratio” from Dr. John Gottman’s research: stable, happy couples maintain about five positive interactions for every negative one. His lab used the pattern to predict divorce with over 90% accuracy — and WHATEVERWEARE scores your green-to-red flags against it.

Where the number comes from

Starting in the 1970s, Gottman and Robert Levenson filmed couples resolving a conflict, then followed up years later. From the balance of positive vs negative moments during conflict, they predicted who would divorce with over 90% accuracy.

It’s a ratio, not a tally

This is why we score flags as a ratio. Five green to one red beats six green to four red — the proportion of warmth to friction is what tracks stability, not the raw count of good things.

The worst sign

Gottman’s research singles out contempt — sarcasm, eye-rolling, disdain — as the single strongest predictor of a relationship ending. It’s the negative that costs the most positives to offset.
