13 science-backed ways to appear more attractive

Yu Han/Business Insider

Attractiveness relies on much more than your physical appearance.

It's in the way you carry yourself, the folks you hang out with, and how you talk to people — plus a whole lot more.

Read on to find out what you can do to make yourself more appealing.

In that study, a psychologist asked three men to tell a joke to their friends at a bar while a woman sat at a nearby table. Then those men were instructed to approach the woman and ask for her number. After the man had left, an experimenter approached the woman and asked her to rate the man on attractiveness and intelligence and to indicate how much she would want to date the man long-term.

Results showed that the guys who told jokes were three times as likely to get the woman's number as the men who didn't. They were also rated more attractive and intelligent.

"The effect of a great sense of humor on women's attractions might be partially explained by the fact that funny people are considered to be more social and more intelligent, things that women seek in a mate," anthropologist Gil Greengross writes.

In one experiment featured in the study, 25 male and female undergrads looked at 300 photos of women's faces, once in a group photo and once in an isolated portrait. Another experiment repeated the same procedure with 18 undergrads looking at photos of men's faces. Results showed that participants rated both men and women significantly more attractive when they were pictured in a group.

"Having a few wingmen or wingwomen may indeed be a good dating strategy, particularly if their facial features complement and average out one's unattractive idiosyncrasies," study authors Drew Walker and Edward Vul write.

In a 1997 study, State University of New York psychologist Arthur Aron and colleagues separated two groups of undergrads and paired them off, giving each duo 45 minutes to answer a set of questions. 

One question set was small talk, and the other was increasingly probing. The people who asked deeper questions felt more connected. One couple even fell in love, an intriguing, though probably insignificant, result.
