What secret force drives us into the arms of one person, while pushing us away from another who might appear equally desirable to any fair observer? Of the many factors influencing our idea of the perfect mate, one of the most telling is our “lovemap” ---- a group of messages formed in our brains that describes our likes and dislikes．It shows our preferences in hair and eye color, in voice, smell, body build．It also records the kind of personality that attracts us, whether it’s the warm and friendly type or the strong silent type．In short, we fall for and go after those people who most clearly fit our lovemap．And this lovemap is determined in childhood．By age eight, the pattern for our ideal mate has already begun to float around in our brains．

The mother has special influence on her sons: she not only gives them clues to what they will find attractive in a mate, but also influences how they feel about women in general．So if she is warm and nice, her sons are going to think that’s the way women are．They will likely grow up warm and responsive lovers and also be helpful around the house．

Just as mothers influence their son’s general feelings toward women, fathers influence their daughter’s general feelings about men．If a father lavishes praise on his daughter and shows that she is a worthwhile person, she’ll feel very good about herself in relation to men．But if the father is cold, critical or absent, the daughter will tend to feel she’s not very lovable or attractive．

While the mother determines in large part what qualities attract us in a mate, it’s the father ----- the first male in our lives ----- who influences how we relate to the opposite sex．Fathers have a great effect on their children’s personalities and chances or marriage happiness．

The idea that some groups of people may be more intelligent than others is one of those hypotheses that dare not speak its name. But Gregory Cochran is (1) to say it anyway.
