⚖️ The 5:1 Rule

The Marriage Math Nobody Talks About

Psychologist John Gottman spent decades watching couples argue in his University of Washington 'Love Lab,' counting every warm glance and every eye-roll. The famous finding: stable couples average 5 positive interactions for every 1 negative one during conflict.

But here's the part almost nobody mentions. Gottman didn't just count and average — he teamed up with James Murray, a mathematician from Oxford and UW, who built actual differential equations, the kind used to model predator-and-prey populations, to track how good and bad moments pile up second by second in a fight. Their book was literally called The Mathematics of Marriage.

⚖️ Bank Your Ratio

1. Notice one small positive today. A thank-you, a compliment, a hand on the shoulder — that's one deposit.
2. Skip the eye-roll when you're annoyed. Contempt and sarcasm count as extra-heavy withdrawals — say the real complaint instead.
3. Repair fast after a rough moment. A genuine 'that came out wrong, let me try again' resets the count.
4. Stack small positives on ordinary days. The ratio is measured over everyday life, not birthdays and big gestures.
