When weâre interested in human social behavior it is a mess, a subject involving brain chemistry, hormones, early experience, sensory cues, prenatal environment, genes, both biological and cultural evolution, and ecological pressures, among other things.
We tend to break down the behavior into buckets of explanation. Putting facts into nice cleanly demarcated buckets of explanation has the advantage that it can help you remember facts better. But it can wreak havoc on your ability to think about those facts. This is because the boundaries between different categories are often arbitrary.
In addition to the interesting comments I have read above, I thought I'd mention another bucket that influences our predispositions towards (or not) monogamy. The following paragraphs are extracted from the book Behave the biology of humans at our best and worst written by Robert Sapolsky.
Oxytocin and vasopressin facilitate mother-infant bond formation and monogamous pair-bonding, decrease anxiety and stress, enhance trust and social affiliation, and make people more cooperative and generous. But this comes with a huge caveatâthese hormones increase prosociality only toward an Us. When dealing with Thems, they make us more ethnocentric and xenophobic. Oxytocin is not a universal luv hormone. Itâs a parochial one. (BTW female aggression is facilitated by oxytocin, estrogen, progesterone).
âŠ.circulating oxytocin levels are elevated in couples when theyâve first hooked up. Furthermore, the higher the levels, the more physical affection, the more behaviors are synchronized, the more long-lasting the relationshipâŠ.
One study suggests that oxytocin unconsciously strengthens the pair-bond. Heterosexual male volunteers, with or without an oxytocin spritz, interacted with an attractive female researcher, doing some nonsense task. Among men in stable relationships, oxytocin increased their distance from the woman an average of four to six inches. Single guys, no effect. (Why didnât oxytocin make them stand closer? The researchers indicated that they were already about as close as one could get away with.) If the experimenter was male, no effect. Moreover, oxytocin caused males in relationships to spend less time looking at pictures of attractive women. Importantly, oxytocin didnât make men rate these women as less attractive; they were simply less interested.
The last exampleâŠ.the visual spectrum is a continuum of wavelengths from violet to red, and it is arbitrary where boundaries are put for different color names (for example, where we see a transition from âblueâ to âgreenâ); as proof of this, different languages arbitrarily split up the visual spectrum at different points in coming up with the words for different colors. Show someone two roughly similar colors. If the color-name boundary in that personâs language happens to fall between the two colors, the person will overestimate the difference between the two. If the colors fall in the same category, the opposite happens. In other words, when you think categorically, you have trouble seeing how similar or different two things are. If you pay lots of attention to where boundaries are, you pay less attention to complete pictures.
