A new study says people lean toward candidates who most resemble them.

You know the old saying that people vote for the best-looking president? Scientists have taken this theory one step further by proving people lean toward candidates who most look like them.

According to researchers at Stanford University, people are subconsciously swayed by candidates who share their facial features.

"The big finding No. 1 is that when we do this, no one has any conscious, explicit idea that it's going on," says lead researcher Jeremy Bailenson, an assistant professor of communication. "The second big finding is that despite the fact they don't consciously detect these processes, it affects their behavior. When the candidate looks more like you, you are more likely to vote for that candidate."

When 600 subjects were divided into two groups, one group was shown photos of the candidates and the other group was shown photos of the candidates with 40% of their facial features morphed with the photo -- a ratio the researchers decided could change a photo enough without anyone consciously noticing.

When test subjects' images were mixed with the candidates, they were much more inclined to vote for them.

Would you be swayed by a candidate's looks?
