A scientific study on love shows that men are increasingly interested in intelligent, educated women with dependable character and emotional stability, and chastity isn't an issue.

The findings by Researchers at the University of Iowa are part of a study quoted by media reports Monday.

Conducted every decade since 1939, the study asks participants to rank a list of 18 characteristics they would want in a partner on a scale ranging from "irrelevant" to "essential."

Included are such items as "sociability" and "good cook, housekeeper," as well as "mutual attraction and love," which came in first place for both men and women in 2008. (In 1939, it wasn't in the top three for either sex.)

Male and female participants in 2008 rounded out their top traits with "dependable character" and "emotional stability, maturity." Men ranked intelligence fourth, a big jump from 11th place in 1939; in addition, "good financial prospect" moved to 12th place in 2008, a shift from its low 17th-place ranking in 1939 and last-place ranking in 1967.

"This is a generation of men who has grown up with educated women as their mothers, teachers, doctors, and role models," said Christine Whelan, head of the study and author of "Marry Smart: The Intelligent Woman's Guide to True Love" (Simon & Schuster, 2008).

"And in tough economic times, sharing the financial burden with a spouse takes the burden off these guys to be the sole provider," she said.

The study's participants were college students from the University of Iowa, the University of Washington, the University of Virginia, and Penn State University.

"Like attracts like, so certainly the fact that we were polling college students would suggest that intelligence and education are going to be important characteristics," Whelan said.

Another notable shift involves the significance of chastity: In 1939, it was valued more than intelligence in women, but in 2008, it was ranked the least important characteristic. Furthermore, it also was ranked the least important for men. This, coupled with the shared top-three ranking for both men and women, suggests a commonality that seems positively modern-day.
