Contrary to popular belief, people have a tendency to choose mates who are a lot like themselves, according to a study conducted by psychologist Dr. Hans J. Eysenck, author of "I Do: How To Choose Your Mate and Have A Happy Marriage." He found that married couples tend to have these factors in common:
Men of average intelligence marry women of average intelligence. People are drawn to someone who communicates at their level.
The age difference between partners is usually within three years.
A divorced person is likely to wed another who's been married. And, people who have never married tend to wed other people who've never been married.
Educational, social, economic and ethnic background
That's because people often marry someone from their own neighborhood, and so the chances are that person will have a very similar background.
Only rarely - and mostly in fairy tales - does beauty marry the beast.
