Significantly impressed by his application of Austrian-school free market economic principles to the issue of polygamy in Economics of Plural Marriage, I was honored when author Michael Anderson offered me the opportunity to review his subsequent essay, Gender Ratio and the ‘Fisher Principle’. Anderson’s keen mind is evident once again as he applies the Fisher Principle of genetics to the particular dynamic of an ongoing imbalance between unmarried women and unmarried men and its impact on polygamy. Nonetheless, given my impression that this more recent analysis was not as on-the-mark as Economics of Plural Marriage, I proposed to both Mr. Anderson and the publisher of Patriarchs’ Journal that it publish the entire Gender Ratio and the ‘Fisher Principle’, followed by my initial assessment of it. Mr. Anderson has also been given the opportunity to respond to my review; a follow-up back-and-forth with Mr. Anderson will be published in a subsequent issue. I want to thank Michael Anderson for his participation in this debate. It is such willingness to engage in serious inquiry that provides meaningful opportunity to challenge our own assumptions and biases. Mr. Anderson’s writing inspired me to move beyond just having an emotional reaction. I thank him for that as well as for his intellectual curiosity and courage.
A lot has been said among advocates of polygamy about an “excess of females” in our current society. Apparently this excess of females can best be handled by allowing some men to have two or more wives. If monogamy is strictly enforced in such a society, the extra women will lower their price to that of less than a demand for life long security, thus leading to increased promiscuity in both sexes. The logic here is generally sound. However, what of the foundational assumption? Are there actually more females than males in our modern culture? As one who was sympathetic with biblical polygamy, I was always intrigued by this supposed “excess of women” and this apparent need for “plural marriage”. One day, I decided to take a look at the U.S. census statistics myself, expecting to have my beliefs confirmed. Instead, I came away somewhat perplexed. The data did not show what I expected.
This is what the United States census generally shows: at birth, there are roughly 105 males for every 100 females. Males die off faster in childhood, and there are about 102 males for every 100 females at about the age of 20. On average, in the 20-45 year bracket, there is a 1/1 ratio of males to females. After that, the male/female ratio drops below 1/1. In the 45-65 year bracket, there is on average, about 94 males for every 100 females. After 65, it drops significantly. By age 70, it's about 82/100. By age 80, it's about 65. And over age 85, it's about 40.
We can see that, in the reproductive years (age 20-45), there is no excess of females at all. However, this does not mean that there is no excess of marriageable women over marriageable men. One way or another (war, disease, accidents), men tend to eliminate themselves from the mating market at a higher rate than women. This has happened numerous times throughout history, and census records have shown this in the past. One example I can think of is Russia after World War II. At that time, there were around 65 marriageable men for every 100 marriageable women due to the massive loss of life in some of the largest scale battles in human history. The typical economic analysis used by advocates of polygamy proved perfectly correct. This unequal gender ratio resulted in a dramatic increase in promiscuity, unwanted children and abortion. But for us in North America in the current generation, disease, accidents, and especially war are not huge killers like they used to be. Other things have taken their place. There are 15 times more males in the prison system than females. There also seems to be more homosexuals and pornography addicts among males than among females. So, in our day, males have found other ways of eliminating themselves from the mating market. I think it's fairly safe to say that, in our culture today, as a result of prison, homosexuality and porn addiction, there are not more than 90 marriageable males for every 100 females.
This observation still requires, at best, that polygyny (one man with more than one wife) should be a relatively rare phenomenon. On average, one man in nine can have an extra wife, in order to avoid the pitfalls of strictly enforced monogamy in a world where there is a slightly low male/female ratio. So, “husband sharing” among women in their fertile years could be useful in this generation, but it loses its usefulness in the following generations. Here is why: in a world where there is greater toleration for polygamy, highly attractive and responsible men will attract more women on average, and highly unattractive and irresponsible men will attract fewer women on average. Men of higher quality will tend to reproduce more, and men of lower quality will reproduce less. Therefore, the manly qualities of responsibility, integrity and self-control, those qualities which tend to steer men away from porn addiction, prison, and other manifestations of immaturity, will tend to spread, and there will, over time, tend to be less of this type of behavior. Probably within a few years, assuming there are no wars, the ratio of marriageable men to marriageable women will once again approach one-to-one, with no reason for polygamy at all (at least not for women in their fertile years).
In my book The Economics of Sex and Marriage, I talk about how a widespread acceptance of polygamy would not necessarily lead to problems since the increased demand for women would simply lead to the development of a bride price. I suggested that this would then lead to an increased production of girl babies (just as an increased demand for any other good will result in an increased production of that good), thus allowing all men to have at least one wife, while allowing some men to have more than one. However, unbeknownst to me at the time, this simply will not work in the long run and there is good reason why no society that lasts will ever adopt such a system. This is due to a phenomenon known as the “Fisher Principle”, which was named after Sir Ronald Fisher (1890-1962), the man who first popularized it. The Fisher Principle explains why there always tends to be an equal number of males and females born in every species of life where there are such things as males and females. This fact rests on two universally-recognized assumptions and the logical implications which flow from them. First, it is a fact that some families tend to produce more male offspring and some families tend to produce more female offspring. Second, the tendency of a couple to produce more of one gender than the other is determined, at least partially, by genetic factors. Here are the implications of these two assumptions: if, for whatever reason, more girl babies are born than boy babies, the boys will have greater reproductive opportunities than the girls. The same goes for the reverse case (more boys than girls). Whichever is the rarer sex will tend to reproduce more on average. Whether polygamy is allowed or not makes no difference. If it isn't allowed, then some of the girls will be left out and won't reproduce. If it is allowed, then all of the girls will reproduce, but the men will reproduce even more. Therefore, families which have a tendency to produce more of the rarer sex will have the most offspring, and families which produce more of the more common sex will have less offspring on average. In this way, the genetic predisposition to have the rarer sex will spread until gender ratio equality is again reached.
But one thing I could not figure out was why the gender ratio at birth is not exactly 1/1 but tends to be consistently 105/100. If the Fisher principle is true, why are there more baby boys than baby girls? After all, wouldn't families that tend to produce more girls, which is the rarer sex at birth, tend to have more offspring and thereby spread girl bearing tendencies until equality is reached? Well, first of all, 105 is not too far away from 100, and it is the mechanism of the Fisher principle which keeps the male/female ratio at birth as low as 105/100. If it went higher, families with more girls would be at an advantage and would spread the tendency to produce girls until the ratio was back at 105/100. But for some reason, the advantage stops there. If it went the other way (100/100), for some reason, families which tend to produce boys would actually be at an advantage and increase the number of boys until it was back to 105/100. So why is this? First of all, “birth” is a rather arbitrary stage of life, at least as far as we're concerned here. You could just as well consider gender ratio at conception, at six months gestation, or gender ratio at age 18 or any age in between. The Fisher principle does not ensure that there will be a one-to-one gender ratio at birth any more than it will ensure a one-to-one gender ratio at conception. Say, for example, there are twice as many girls conceived as boys, and girls die in miscarriages roughly twice as often as boys. The Fisher principle would not equalize the gender ratio at conception, because the parents simply replaced them, and as far as this analysis is concerned, it's as if those miscarried babies never existed. Similarly, if, in every generation, half the 19-year-old men die in battle, this will not cause a doubling of the male birth rate due to the Fisher principle, since their parents are mostly too old to replace them. Every female-dominant family, on average, will have exactly the same reduction in offspring as every male-dominant family by such a war. So there is no tendency to spread female-dominant families. There is no advantage for the rarer sex. The Fisher principle only insures that there will be a roughly one-to-one gender ratio at the point which, on average, couples are no longer willing or able to replace their deceased offspring (perhaps sometime in the teen years).
So what's wrong with artificially tampering with the gender ratio at birth so as to provide more wives for men? The Fisher principle does not care what actually causes the gender ratio to be tipped too far one way or the other. It will seek to equalize it no matter what. If polygamy became commonly accepted, which, of course, is the dream of anyone who advocates it, more men would actively pursue multiple women. This follows necessarily. If you lower the cost (social ostracism) that one must pay in order to engage in an activity, the demand for such activity will rise in accordance with economic law. As I mentioned in my book, such an increase in demand for women would lower the age at which women will get married to the point where the men are practically always dealing with the girl's parents. This would necessarily lead to the development of a bride price system. (This is, of course, a best case scenario. This assumes that no one resorts to violence.) The appearance of rising bride prices would necessarily motivate people to use artificial means to produce more girls than boys. At first, there would be more females than males, thus temporarily satisfying the increased demand for women. But, in accordance with the Fisher principle, families which produce more males (the rarer sex), would tend to have more offspring, and thus, the tendency to have males would spread, pushing the gender ratio closer to one-to-one again. And remember, in such a world, families who produce mostly males do so in spite of the presence of a large financial incentive to produce girls. So either they are families that instinctively value males so much more than females that they are willing to forgo the huge reward associated with producing a female, or, they are families who tried to have girls but their tendency to have males was so strong that they couldn't. These are the instincts and tendencies which will tend to proliferate in such a world.
If such a population persists in its desire to practice polygamy, the bride price must rise further and further in order to combat the inexorable work of the Fisher principle in equalizing the gender ratio. Remember, even men who only marry one wife must pay this ever-rising bride price. After several generations, an extremely large number of boys are the progeny of polygamous men, that is, men who had an extremely high desire for women and the qualities to attract those women. The sons of such men, will, by and large, inherit these characteristics. Such male offspring will never idly sit by and let other men have two or more wives while they have none. Eventually, the bride price will rise so high that the men will be forced to compete using the only alternative to a peaceful method – violence. In the meantime, as the Fisher Principle continues to raise the male/female ratio, the female birth rate is maintained by ever more desperate and artificial measures. If somehow, the bride price disappeared, and the incentive to have girl babies drastically decreased, practically everyone would have male offspring and almost no one would have female offspring. Everyone would instinctively value boy babies far more than girl babies. (In fact, this might explain why, in many cultures around the world, boy babies are valued so much more than girls. Perhaps, these cultures had a fair amount of polygamy in their past.) A society where polygamy was commonly accepted and practiced widely for several generations would necessarily become more violent, either externally, like ancient Israel in the conquest of Canaan or the Muslims in the first few centuries after Mohammed, or internally, which results in weakness and vulnerability to being conquered by others. Only cultures whose members seem to have a somewhat instinctual aversion to polygamy can possibly survive and thrive in the long run, without the constant need to rapidly expand at the expense of others. Such cultures would tend to gradually out-compete and dominate the necessarily weaker and more internally-violent cultures which have no qualms about accepting polygamy. Examples of such robust and powerful monogamous civilizations are ancient Babylon (where polygamy was restricted for the common man to cases of infertility), and outwardly monogamous ancient Greece, Rome, and their cultural descendants, Europe and America.
The process I described above, of permanently rising bride prices facing the constant pressure of the Fisher Principle, can only be reversed by an almost total abandonment of polygamy. If such a society declared that men, typically, should have only one wife (specifically, only one fertile wife), the demand for women would drop, bride prices would drop, fewer parents would intentionally have girl babies, girls would become a little rarer than boys, which would tend to cause a natural increase in girl-bearing tendencies. And since men, in every generation, seem to somehow eliminate themselves from the mating market at a slightly higher rate than females, over time the bride price would be bid down, which would gradually decrease reliance on artificial means to produce girl babies and increase the frequency of natural conceptions of female babies. Eventually, a roughly one-to-one ratio could be restored.
Keeping the Fisher Principle in mind, and applying a little deductive reasoning, it's easy to see why the average person (whether male of female) in modern Western Civilization reacts with such disgust, revulsion and unthinking emotionality to the idea of a man having more than one wife. We are literally genetically predisposed to be that way. Natural selection has made it this way. Our civilization is a dominant one, and civilizations which dominate in the long run must have this characteristic.
To avoid the pitfalls of widespread acceptance of polygamy as well as the pitfalls of strictly-enforced monogamy in the real world of wars, disease, prison, homosexuality and pornography, my personal opinion is that monogamy should be the general norm for the vast majority of people, with polygamy being acceptable only under certain rare circumstances. This would ensure a secure home for all the “extra” women (most of whom are above age 45, anyway), as well as avoiding the development of a bride price high enough to induce an artificial increase in the female birth rate (and all the aforementioned difficulties associated with that). Of course, this would lead to an increase in the value of women, a decrease in the level of promiscuity (assuming the welfare state is also abolished), and a massive decrease in the production of unwanted babies (as well as abortions). As more and more children are born into higher-quality and stable families, more and more of the adult population (particularly the adult male population) will be responsible, moral and mature. This fact would cause a reduction in the rates of crime, pornography and other behaviors associated with irresponsibility and immaturity. More of the men will be “husband material”. And this would totally eliminate the need for polygyny, except, perhaps among older people (45 and above).

I suspect I'm not at all out of the ordinary in this regard among men seeking or supportive of polygamy: I am not only a sexual being, I'm a sexual being who wants lots of sex -- more than what most men want and certainly more sex than most individual women desire. Therefore, it is only natural and appropriate based on the way that God created me that I would have as one of my most primary motivations for seeking another wife that I'm looking to increase the frequency of my sexual opportunities, AND I WILL NOT APOLOGIZE FOR IT.

As more and more children are born into higher-quality and stable families, more and more of the adult population (particularly the adult male population) will be responsible, moral and mature. This fact would cause a reduction in the rates of crime, pornography and other behaviors associated with irresponsibility and immaturity. More of the men will be “husband material”. And this would totally eliminate the need for polygyny, except, perhaps among older people (45 and above).
