WASHINGTON POST - Feb 12 - In one study conducted by economist Raymond Fisman and colleagues for Columbia University, 392 singles were invited to participate in a speed-dating event. Each participant went on 10 - 20 four-minute dates. They then rated them on a 1-to-10 scale and indicated whether they would like that person's contact. 43%of them requested the contact information of the person they had just met. The data collected reveals that both men and women really care a lot about attractiveness (though men care ever so slightly more). However, women care about intelligence roughly twice as much as men. Men valued women's intelligence only until it matched their own, and they actually found women whose ambition exceeded theirs to be off-putting. A team of economists at the University of Chicago showed that when women out-earn their husbands, marital satisfaction is lower, and divorce is more likely.
