What is the Gottman Magic Ratio?
The Magic Ratio is one of the most reliable findings in relationship science: in stable, happy relationships, partners maintain about five positive interactions for every one negative interaction — a 5:1 ratio — especially during conflict.
It comes from decades of research by Drs. John and Julie Gottman, who observed thousands of couples in their "Love Lab" and tracked which relationships lasted. Couples who stayed together kept their positives well ahead of their negatives. Couples heading for separation let the ratio slip toward 1:1 or below.
