Do people know what they want: A similar or complementary partner?

From the book : Evolutionary Psychology 6 issue 4 : 595-602.
The present study examined the extent to which individuals seek partners with similar, as opposed to complementary, personality characteristics.
Results showed that whereas individuals desired a partner who resembles them in terms of personality, when asked about their preferences in general, most individuals indicated that they desired a complementary partner instead of a similar one.
In addition to a similar partner with regard to personality, women also desired a more conscientious, less neurotic and more extraverted partner than men.
These results are discussed with reference to the importance of matched personalities in marital success.
