Do opposites really attract? Probably not. A new study from pnas.org indicates that people are more attracted to people they can better understand socially and emotionally, and that usually means someone much like ourselves. The study states:
"The greater the match, the larger the brain’s intrinsic reward signal."
In other words, the more like our partner we are, the better chance we have of having a positive emotional response.
EOnline took a sample of celebrity couples' faces and put them side by side, noting just how similar they were to each other. For instance, take a look at this picture of Cash Warren and Jessica Alba:
Pretty close, right?
