It's not quite so strange when you really think about it: How many times have you looked at a couple and remarked that they could be brother and sister? Those strange similarities a couple can share are no coincidence. Genetically, we have been trained to seek out those who have a face similar to our own, says founder of FindYourFacemate.com, Christina Bloom.
"There's part of the brain that's just focused on processing faces. It's the fusiform gyri. It's so important that we have a special area in our brain for it," Bloom says. "If you think about human beings before we had language, or if you think about the way babies are -- we learn things visually. That makes sense because that's how we mated. We just know what we like."
Bloom points to several examples of couples who have similar faces -- Halle Berry and Olivier Martinez, and Tom Hanks and Rita Wilson, for instance. She believes that matching people by their face shapes will ultimately lead to better chemistry and, hopefully, better coupling.
"After meeting [a date], you think of, 'Wow, it's because of his or her great personality, that's why I like them.' Well no," she says. "You already saw his or her face, and you were interested because of his or her face."
Bloom says that the criteria for a good match comes in this descending order: chemistry, style, values and personality. That's why her website puts looks first and foremost. After uploading a photo, the site's algorithm analyzes 11 points on the face and matches it with others who share those traits. In the next three months, Bloom hopes to improve the algorithm by using 62 points on the face for more specialized matches.
To Bloom, the website is just helping us do what we already intuitively know how to do.
"I've been looking at couples for 20-plus years, and I just think it's innate," she says. "Basically, we're doing it without even knowing that we're doing it. I do not know how people don't see it."
