I read 'Don't trust your gut', it's written by a former Google data scientist who ran studies with Big data, machine learning to understand the 'truth' behind relationships.
He used millions of data points from Google searches, OkCupid, Match.com, Tinder swipes, and long-term marriage studies.
Here’s what they did:
1- They tracked who swipes right, who messages back, who actually goes on dates.
2- Analyzed anonymous Google search data , which is where people tell the truth when they won’t tell their friends.
3- They matched this with long-term surveys of married couples , who stayed happy, who divorced, and why.
Data showed , almost everything people think matters in dating doesn’t actually predict whether you’ll be happy later.
Here's the top 10 insights via data:
1. Emotional stability is the best predictor of long term success.
2. The people who feel an instant “spark” often burn out fast. Couples who start slow, build up, and actually like each other as people stick together longer.
3. Height is the dumbest filter. Tons of women filter for “6 feet and up” but data shows it makes zero difference to long-term happiness.
4. Attractiveness of women is overrated. Beautiful people do get more swipes, but they don’t stay together more than average-looking people who treat each other well.
5. Drama is the poison for long term love.
6. Opposites rarely last. The strongest couples have shared habits, life goals, and values matter way more than some fake “opposites attract” fantasy.
7. The idea of ‘settling’ is flawed. Data shows that satisficers, people happy with ‘good enough’ are more satisfied than maximizers (who always think there's someone better out there)
8. The more rigid your checklist, the more likely you’re single forever. The people who are happiest didn’t find a perfect fit, they found someone good enough and built a good life.
9. Marrying very early, large difference in education & religion skyrockets chances of divorce.
10. Similar levels of conscientiousness predict a durable marriage, this was big!
It's a solid book, it also shows data about work, carrer, parenting! Worth reading if you like data & numbers..
