I Was Thinking About Why We (Humans) Are Physically Attracted To Some People And My Thought Process Was Along These Lines, "The Reason We Find Some People Attractive Is Because We Unconsciously Want To Pass His Or Her Attractive Physical Traits On To Our Offspring. In Other Words, When We're Attracted To Someone We Unconsciously Reason That He Or She Will Most Likely Produce Offspring With The Physical Traits That We're Attracted To And That A Future Generation Of Mates Will Be Attracted To As Well, So We Want To Acquire Those Attractive Traits For Our Potential Offspring." The Same Goes For Personality Traits. When We Talk To Someone And Become Attracted To Them It's Because We Want Our Future Offspring To Inherit These Personality Traits That We Find Attractive. Essentially, Our Choice In Mates Comes Down To Who Can Produce Offspring With Traits That Will Lead To The Highest Reproductive Success. We're Unconsciously Seeking Mates With Those Genes That Will Lead To The Greatest Reproductive Success We Can Achieve (What Physical And Psychological Traits Will Attract Mates And Lead To High Reproductive Success). (I HAVE CHILDLIKE THOUGHTS! YOU KNOW WHAT HAPPENED TO THOUGHT, RIGHT?)
They Both Have Feminine, Paedomorphic Features. They Both Look Like Young Girls!

Meta-analyses of 22 traits and UK Biobank analyses of 133 traits by Horwitz et al find widespread evidence of mate similarity, particularly for social attitudes, education, and substance use traits:
https://buff.ly/N7dZpsw
The most similar characteristics of couples (82,398 couples):
- Education duration (r=0.45)
- Weekly alcohol consumption (r=0.42)
- Smoking cessation status (r=0.33)
- Body mass index (r=0.26)
- Height (r=0.24)
- Smoking initiation status (r=0.23)
Do couples assort on personality? Yeah, a little bit. A lot for education, politics, and religion.
Meta-analysis: Partners in romantic relationships look similarly good. https://sciencedirect.com/science/article/abs/pii/S0191886924001909… Do people in opposite-sex romantic relationships have similar physical attractiveness, as reflected in self-reports and observations made by others? Do people who perceive themselves as physically attractive form romantic relationships with partners who are objectively similarly attractive? Using correlations gleaned from a prior meta-analysis of opposite-sex romantic couples, we performed a novel dyadic secondary meta-analysis to examine associations between men’s and women’s third-party observed and selfreported physical attractiveness in a dyadic context. Supporting an assortative mating account, both observed and self-reported physical attractiveness correlated positively within couples: More attractive people had partners who were more attractive, regardless of whether third-party observations or self-reports were considered. People who viewed themselves as more attractive also had partners who were more attractive. Second, observed and self-reported physical attractiveness were positively correlated for both men and women, implying that people were accurate in their judgments of others’ ratings of their own physical attractiveness, or alternately, people’s self-ratings were informed by the feedback they received from others about their physical attractiveness..
HEY, THESE TWO LOOK THE SAME, HUH? THEY HAVE SIMILAR FACIAL FEATURES DON'T THEY? YEAH, THEY DO. IN FACT, THE ONLY MAJOR DIFFERENCES BETWEEN THEM IS THAT ONE IS WHITE WITH LONG, STRAIGHT HAIR AND THE OTHER IS BLACK WITH SHORT, COILED HAIR. OH, AND ONE HAS A LONGER, MORE NARROW FACE, WHILE THE OTHER HAS A SHORTER, ROUNDER FACE. BUT OTHER THAN THIS, THEY PRETTY MUCH LOOK THE SAME. READ THE CHAPTER ENTITLED "HOW WE PICK OUR MATES AND SEX PARTNERS" ON pg. 84* IN THE BOOK THE THIRD CHIMPANZEE WHICH IS LINKED BELOW (WE UNCONSCIOUSLY CHOOSE OUR MATES BASED ON THEIR PHYSICAL SIMILARITY TO US. IF YOU HAVE A LONG NOSE THERE'S A GOOD CHANCE THAT YOU'LL CHOOSE A MATE WITH A LONG NOSE, IF YOU A HAVE SQUARED JAWLINE THERE'S A GOOD CHANCE THAT YOU'LL CHOOSE A MATE WITH A SQUARED JAWLINE, ETC., ETC., ETC.).
I'M A SQUARE!
THESE TWO LOOK SOMEWHAT SIMILAR, TOO, ESPECIALLY IN REGARD TO THE NOSE AND MOUTH AREA.
And How About She And Her Hubby?! Pretty Similar, Wouldn't You Say?

What about matching of husbands and wives for physical characteristics? The answer is not one that would leap out at you immediately if you just looked at a few married couples. That is because we do not select our own mates for their bodies as carefully as we select the mates of our show dogs, racehorses, and beef cattle. But we select nevertheless. If you measure enough couples, the answer that finally emerges is unexpectedly simple. On the average, spouses resemble each other slightly but significantly in almost every physical feature examined. That is true of all the obvious traits you would first think of when asked to design your ideal beloved — his or her height, weight, hair colour, eye colour, and skin colour — but it is also true of an astonishing variety of other traits that you probably would not have mentioned in your description of the perfect sex partner. Those other traits include ones as diverse as breadth of nose, length of ear lobe or middle finger, circumference of wrist, distance between eyes, and lung volume! Experimenters have made this finding for people as diverse as Poles in Poland, Americans in Michigan, and Africans in Chad. If you do not believe it, try noting eye colours (or measuring ear lobes) the next time you are at a dinner party with many couples, and then get your pocket calculator to give you the correlation coefficient. Coefficients for physical traits are on the average +0.2- not so high as for personality traits (+0.4) or religion (+0.9),but still significantly higher than zero. For a few physical traits the correlation is even higher than 0.2-for instance, an astonishing 0.61 for length of middle finger. At least unconsciously people care more about their spouse's middle finger length than about his or her hair colour and intelligence!
We Have Genes That Predispose Us To Be Attracted, Specifically On An Unconscious Level, To People That Have Different Genes Than Us (Particularly Genes That Create And Regulate Our Immune System; HLA Or Human Leukocyte Antigen). Why? Because Breeding With People Who Are Genetically Different Than Us Increases The Genetic Heterozygosity Of Our HLA System And Thus Gives Us The Genes To Create A More Robust Immune System Which Can Fight Off More Diseases.
If You're Genetically And Biochemically Incompatible With A Potential Mate Your Potential Relationship With He Or She Won't Flourish Or Even Develop, For That Matter. If There's Too Much Genetic And Biochemical Conflict Between You And Your Potential Mate You'll Be Able To Detect It Unconsciously Through The Senses (Sight, Smell, Taste, Etc.), So Always Go With Your Gut Instincts.
Many kinds of animals are capable of what biologists call kin recognition. It tells them which members of their species to be nice to and which to be nasty to. A paper wasp, for instance, decides whether another paper wasp, seeking admission to the nest, is one of us or one of them by smelling it. If the newcomer smells like us, it is allowed to enter. Tiger salamanders can recognize their own siblings, also on the basis of smell. If you rear them among nonsiblings they often become cannibals. They don't mind eating other salamanders, but they'd rather not eat their own brothers and sisters. Kin recognition by means of odors is based on a biochemical mechanism similar to the one that permits your immune system to distinguish between "self" and "nonself".
Humans recognize kin, not on the basis of odors, but on the basis of familiarity. A sister or brother is someone you grew up with. People don't marry their sisters or brothers, not because it's against the law, but because they don't want to. Israelis who grew up in a kibbutz where boys and girls were reared together, treated like brothers and sisters, don't marry each other.
But people are nonetheless attracted to others who are similar to themselves. Husbands and wives are, on average, much more alike than they would be if Cupid fired off his arrows at random. The ways in which married couples tend to resemble each other include race, religion, socioeconomic class, IQ, education, attitudes, personality characteristics, height, breadth of nose, and distance between the eyes. Married couples don't come to look alike as they grow older: they look alike to begin with.
Similarity also serves as a basis for friendship. Even in nursery school, a child is attracted to others "like me." In grade school, children who are good friends are likely to be of the same age, sex, and race, and to have similar interests and values.
I believe the tendency to be drawn to people who are similar to yourself has its remote origins in kin recognition. If you were a hunter-gatherer, someone who looked like you and spoke your language was more likely to be a member of your group, possibly a relative, than someone who didn't look like you and spoke a language you couldn't understand. If you are an educated North American, you find yourself wanting to trust someone who looks like you, talks like you, and thinks like you.
The stranger is instinctively distrusted, by paper wasps and human babies, because he may be up to no good. If he is a cannibal - cannibalism is found in many species, including our own - he might eat you, because you are not his kin. The first reaction to the stranger, or to the one who is behaving strangely, is fear. Fear turns into hostility because being afraid is unpleasant. Remember the polio-stricken chimpanzee who dragged himself, crippled, back to his group? His groupmates reacted first with fear and then anger - they attacked him. Damn you for giving us such a fright!
We don't need a fancy cognitive explanation for hostility toward other groups - evolution provides a good one, and it works for animals as well as people. Group contrast effects, which exaggerate the differences between groups or create differences if there are none to begin with, are not (as far as I know) found in animals, but they are a direct consequence of the human and animal tendency to feel hostile toward other groups. If you fear and dislike someone, you are motivated to be as different from them as possible. Humans - adaptable creatures that they are - are ingenious at finding ways of being different from the members of other groups. (The Nurture Assumption)
Our friendships do not rely solely on demographic similarities such as age or gender; our implicit mental processes—such as how we perceive the world in an instant, how we focus our attention on events, and what makes us laugh or emotional—exhibit an extraordinary similarity with those of our friends.

People marry other people with similar intelligence to a greater extent than any other trait.
