The matching hypothesis suggests that we are more likely to end up with a partner similar to ourselves in physical attractiveness and other assets than someone who is different than us.

The matching hypothesis proposes that individuals tend to choose partners with similar levels of physical attractiveness, intelligence, and social status, among other traits. This is thought to help maintain a balanced and stable relationship, and reduce the likelihood of competition or conflict over resources. While there are some exceptions to this pattern, such as when individuals prioritize other factors like personality or values over physical appearance, research generally supports the idea that people tend to choose partners who are similar to themselves in a variety of ways.
