dysgenics

magazine.]]

Dysgenics refers to a genetic deterioration of a population or populations and the study of such processes.<ref name=D2011/><ref>Dysgenics. Merriam-Webster. http://www.merriam-webster.com/medical/dysgenics</ref><ref>Dysgenics. Dictionary.com. http://dictionary.reference.com/browse/dysgenics?</ref>

It may occur both through internal factors (such as the more intelligent in a population having lower fertility) and/or external factors (such as race mixing with another population with lower intelligence).

A large number of studies on average IQ have stated declining average genotypic IQ in developed countries. Until recently, this has been argued to be concealed regarding average phenotypic (measured) IQ by the environmentally caused Flynn effect. Recent studies and literature reviews have instead stated declining average phenotypic (measured) IQ in several developed countries with, for example, a study on France stating that the measured average IQ declined by 3.8 points during the 1999–2008/9 time period.<ref name=France1/><ref name=France2/><ref name=<ref name=Dutton/>

Several IQ researchers have expressed very pessimistic views regarding the future of Western civilization due to dysgenic trends.

Etymology

Dysgenics was coined in 1915 for the genetic deterioration in modern human populations that eugenics aimed to correct.<ref name=D2011>Richard Lynn. Dysgenics: Genetic Deterioration in Modern Populations. 2nd Revised Edition. 2011. Ulster Institute for Social Research</ref>

Dysgenic effects in early societies

Dysgenic processes have been argued to be an important cause of the decline and fall of many advanced historical civilizations, such as of Ancient Greece and Ancient Rome.<ref name=raowe>The Rise and Decline of the West: Review “At Our Wit’s End” by Edward Dutton and Michael A. Woodley of Menie https://www.theoccidentalobserver.net/2019/02/12/the-rise-and-decline-of-the-west-review-at-our-wits-end-by-edward-dutton-and-michael-a-woodley-of-menie/</ref><ref name=D2011/>

The decline of Muslim, or more narrowly Arab societies, after the initial large achievements, has been argued to have possible dysgenic causes. An extensive interbreeding with females slaves from sub-Saharan Africa is argued to have occurred. It has been argued that Middle Easterners and North Africans are now darker than they used to be earlier. Another explanation is widespread use of contraception, especially by those with higher IQ, in contrast to Europe, where the Catholic church for a long time successfully condemned contraception. Still another explanation is that the rote memorization, simple dogmatism, and absence of abstract principles and analysis argued to have characterized Muslim education and religion would have not favored those with high intelligence. There may also have been relatively less need for high intelligence after the successful conquests were completed. Yet another explanation is that many of the early achievements of Muslim societies were actually accomplished by non-Muslims.<ref name=templer>Donald I. Templer. The Comparison of Mean IQ in Muslim and Non-Muslim Countries. Mankind Quarterly, Vol. 50, No. 3 (Spring 2010) pp. 188-209. http://www.mankindquarterly.org/spring2010_templer.html</ref>

The prohibition of polygamy by the Catholic church has been argued to have caused a dysgenic effect by making it easier for less achieving men to find wives. However, it has also been argued that polygamy in other societies caused the importing of female slaves from low IQ groups and dysgenic race mixing. The decision to require celibacy of priests has been argued to be dysgenic, since men with the degree of intelligence needed to become priests were at least in theory forced to be childless. On the other hand, the Catholic church banned contraception, which on average is used more effectively by the intelligent. However, more recently, the continued Catholic opposition to contraception, now rather ineffectual in Western countries, contributes to, for example, the very rapid population growth in Sub-Saharan Africa.<ref name=review>The Decline of the West.

Dysgenic effects in modern societies

During the mid-nineteenth century, several scientists, including Charles Darwin, began to worry about and find empirical evidence for that the genetic quality of Western nations was deteriorating. The earlier natural selection had changed, such as by improved public health and reduced infant and childhood mortality, meaning that more of the less achieving members of society reproduced successfully. Furthermore, the most able members of society tended to have few children. One proposed cause for this was marrying late, due to the demands of a career. Another explanation was that many successful men married wealthy heiresses, who become heiresses by coming from families with genetically low fertility, as shown by having no male children who could inherit. A more plausible and general explanation may be the more efficient use of contraception by the successful, due to factors such as higher intelligence and more restraint, farsightedness and the capacity to delay gratification. Such arguments and supporting research became increasingly widespread and contributed to the rise of the eugenics movement.<ref name=D2011/>

After World War II, research and public discussion on dysgenics and eugenics increasingly became rejected and taboo subjects. Another trend after WWII is the mass immigration to Western countries of people from races with different genetics and often an argued lower average genetic intelligence.<ref name=D2011/>

It has also been argued that mass killings and class warfare, such as during the French Revolution and during Communist rule, had a dysgenic effect through the killing of the more intelligent by the less intelligent.<ref>

</ref> Another argument is that especially modern warfare may have had a dysgenic effect, due to the healthy selectively being drafted and killed, while preserving the unfit at home. Also earlier wars, such as the fratricidal civil wars in ancient Greece and ancient Rome, have been argued to have had a dysgenic effect.<ref name=“Jordan”>

</ref><ref>Sacrificing the Best https://www.amren.com/news/2017/05/war-and-the-breed-david-starr-jordan-war-dysgenics/</ref> However, such effects may have been limited to particular regions during particular periods.

The concern has mainly been regarding three areas: deteriorating genetic health, deteriorating genetic personality (“moral character”), and deteriorating genetic intelligence.<ref name=D2011/>

Health

Improved medical and social care may possibly lead to increased incidences of genetic disorders and genetically influenced disorders. Practices such as genetic counseling and prenatal screening may possibly counteract this effect, for the disorders for which this is done.<ref>Holloway, S. M.; Smith, C. (1975). “Effects of various medical and social pracitices on the frequency of genetic disorders”.

People with Down syndrome used to not be allowed to have children. Today they are allowed. They have a 50% chance of having a child with Down syndrome.<ref>http://www.thesebrokenvases.com/2010/10/down-syndrome-awareness-can-people-with.html</ref>

It has been estimated that over the next 30 years in developed countries, there will be a 26 percent increase in hemophilia and a 120 percent increase in cystic fibrosis.<ref name=review/>

Personality

Those worried about dysgenics have considered traits such as self-discipline, work motivation, energy, ambition, and strong moral sense, that are argued to contribute greatly to a person's achievements, but in modern populations are argued to contribute less to reproductive success than previously. A modern term for many of these traits is conscientiousness.<ref name=D2011/>

Conscientiousness has a high heritability.<ref name=review/>

Richard Lynn in a 1995 study of a sample of British criminal convicts found that they had an average fertility of 3.91 children. The general population had an average fertility of 2.1.<ref>Lynn, R. (2008). “Dysgenic fertility for criminal behaviour”. Journal of Biosocial Science 27 (4). http://dx.doi.org/10.1017/S0021932000023014</ref>

Intelligence

Examples of studies finding declining average IQ

Many studies have stated declining average genotypic IQ due to dysgenic effects. Some examples of such studies are mentioned in this and the following sections. Recent studies have also found declining average phenotypic IQ. These studies are discussed in the section “The Flynn Effect”.

A 2010 study stated that in the absence of migration and with constant environment, genetic selection would reduce the average IQ of the US population by about 0.8 points per generation.<ref name=mg2010>Meisenberg, Gerhard (2010). “The reproduction of intelligence”. Intelligence 38 (2): 220–230. http://dx.doi.org/10.1016/j.intell.2010.01.003</ref> Although such a number may seem small, over time this adds up to a substantial effect since the start of the dysgenic trends.

Richard Lynn has predicted that, given the mix of low-IQ people coming to the United States, there will be a 4.4 point decline in average IQ between 2000 and 2050. He expects gentler declines in Canada and New Zealand because they receive relatively more high-IQ Chinese immigrants. Between 2000 and 2050, there should be a world-wide decline of 1.29 IQ points per generation.<ref name=review/>

The average IQ of Denmark was in 2012 predicted to decline from 98 in 1979 to 93 in 2072.<ref>Helmuth Nyborg, The decay of Western civilization: Double relaxed Darwinian Selection, Personality and Individual Differences, Volume 53, Issue 2, July 2012, Pages 118-125, ISSN 0191-8869, 10.1016/j.paid.2011.02.031 http://www.sciencedirect.com/science/article/pii/S0191886911001073</ref>

A review of the 2018 book At Our Wit’s End: Why We’re Becoming Less Intelligent and What It Means for Our Future stated that “Today we can confirm that hereditary intelligence has been declining. Dutton and Woodley summarize the evidence, which includes deterioration in simple reaction times, color discrimination, the use of “difficult” words, working memory, special perception, child developmental schedules and—most critically—frequency of macro-innovations. In 2017, an Icelandic study found the first direct genetic evidence that a set of alleles predictive of g has been declining in frequency in that country’s population. More such studies can be expected in the years ahead. According to a 2015 meta-analysis of studies conducted since 1927, IQ in the USA and the UK appears to be declining at a rate of 0.39 points per decade. Declines are also reported in Russia and a number of non-Western countries.”<ref name=raowe/>

A 2013 study found that the average reaction in time in Western countries had declined greatly during the 1889-2004 time period. The decline was equivalent to − 1.16 IQ points per decade or − 13.35 IQ since Victorian times. Reaction time is an indirect measure of IQ and in particular of genotypic IQ.<ref>Michael A. Woodley, Jan te Nijenhuis, Raegan Murphy, Were the Victorians cleverer than us? The decline in general intelligence estimated from a meta-analysis of the slowing of simple reaction time, Intelligence, Available online 7 May 2013, ISSN 0160-2896, 10.1016/j.intell.2013.04.006 http://www.sciencedirect.com/science/article/pii/S0160289613000470</ref>

Later studies criticizing this have made arguments such as methodological problems making it impossible to make comparisons, or that there has been a decline, but that it is impossible to tell how large.<ref>Yulia A. Dodonova, Yury S. Dodonov, Is there any evidence of historical slowing of reaction time?

A 2015 study examining the degree of craniofacial asymmetry for Whites in the US during the past 150 years found increasing asymmetry. This was argued to indicate increasing instability during development, with this being harmful to IQ, and possibly related to several different factors (see the section “Causes: Other explanations).<ref name=ds/>

Genetic markers

A 2016 study using genetic markers stated declining average genotypic IQ and stated that ”based on these results, polygenic selection might be reducing heritable G globally by −0.253 points per decade“.<ref>Menie, M. A. W., Piffer, D., Peñaherrera, M. A., & Rindermann, H. (2016). Evidence of contemporary polygenic selection on the Big G of national cognitive ability: A cross-cultural sociogenetic analysis. Personality and Individual Differences, 102, 90-97 http://www.sciencedirect.com/science/article/pii/S0191886916308042</ref>

Smart fraction

Due to the shape of normal distributions (“bell curve” distributions), such as IQ, a change regarding the average value would be disproportionately larger at the extreme IQs. A decline in average psychometric intelligence of only a few points will mean a much smaller population of gifted individuals.<ref>Weyl, N. & Possony, S. T: The Geography of Intellect, 1963, s. 154</ref> See the Smart fraction article.

Causes: Dysgenic fertility

A large number of studies, particularly in the United States, have found that higher intelligence is associated with lower fertility.<ref name=D2011/> One example is a 2010 study finding that IQ in the US was negatively related to the number of children, with age-controlled correlations of −.156, −.069, −.235 and −.028 for White females, White males, Black females and Black males. ”This effect is related mainly to the g-factor. It is mediated in part by education and income, and to a lesser extent by the more “liberal” gender attitudes of more intelligent people.“<ref name=mg2010/>

One explanation for the relationship between high IQ and low fertility is that higher income is associated with higher IQ. It is well-known that a country's fertility declines as the average income rises. This is sometimes referred to as the demographic transition. It has been argued to be due to a variety of causes. However, several of the studies mentioned above have examined this and have found that higher income do is an explanation, but that IQ also has an effect independent of this. Similarly, studies have also controlled for education and other possible confounding factors.

A large proportion of children are unplanned, which is related to IQ. A review stated that ”Part of the problem is that those of low educational level are less likely to use contraception. Yet even among a sample of women using the same highly-effective methods, those with lower IQs were found to have much higher failure rates. Percentages having unwanted births during a three-year interval were 3%, 8% and 11% for high, medium and low IQ women, respectively. For those not using one of these methods, the percentages were 15%, 23 and 31% (Udry, 1978). After an unwanted pregnancy has occurred, higher IQ couples are more likely to obtain abortions (Cohen, 1978). Unmarried teenage girls who become pregnant are more likely to carry and deliver a baby than to have an abortion if they are doing poorly in school (Olson, 1980). Thus, each factor–from initially employing some form of contraception, to successful implementation of the method, to termination of an accidental pregnancy when it occurs–involves selection against intelligence. […] 18% of American women said they desire more children than they expect to have. Highly educated women were more likely to fall into the “deficit fertility” category.“<ref>Van Court, Marian (1983). “Unwanted Births And Dysgenic Reproduction In The United States”. Eugenics Bulletin. http://www.prometheism.net/dysgenic2/</ref>

Other argued contributing factors include people with higher IQ postponing children due to higher education, the modern welfare state that taxes the more successful in order to support single mothers (who can often increase their benefits by having more children), and feminism encouraging the brightest women to pursue careers and postpone marriage, often until it is too late.<ref name=raowe/>

Other studies have demonstrated the relationship between high IQ and low fertility in other developed countries.<ref name=D2011/>

A 2016 study on China stated that the estimated IQ decline owing to dysgenic fertility came out to 0.31 points per decade between 1986 and 2000. The total loss from 1971 to 2000 due to dysgenic fertility was estimated to be 0.75 points.<ref>Wang, M., Fuerst, J., & Ren, J. (2016). Evidence of dysgenic fertility in China. Intelligence, 57, 15-24. http://www.sciencedirect.com/science/article/pii/S0160289616301106</ref> A 2017 study found dysgenic effects on IQ also in Taiwan, with the effect being stronger for younger adults.<ref>Chen, H. Y., Chen, Y. H., Liao, Y. K., Chen, H. P., & Lynn, R. (2017). Dysgenic fertility for intelligence and education in Taiwan. Intelligence, 63, 29-32. http://www.sciencedirect.com/science/article/pii/S0160289616303038</ref>

There is also some evidence supporting dysgenic fertility regarding IQ in India.<ref>Lynn, R., & Yadav, P. (2015). Differences in cognitive ability, per capita income, infant mortality, fertility and latitude across the states of India. Intelligence, 49, 179-185. http://www.sciencedirect.com/science/article/pii/S0160289615000148</ref>

A 2005 study of the Afro-Caribbean population of the Caribbean country Dominica found a weak dysgenic relationship.<ref name=“LynnHarvey2008”>Lynn, R.; Harvey, J. (2008). “The decline of the world's IQ”. Intelligence 36 (2): 112. http://dx.doi.org/10.1016/j.intell.2007.03.004</ref>

There are also studies which have argued that the world's genotypic IQ is declining, since countries with higher IQ have lower fertility than countries with lower IQ.<ref name=“LynnHarvey2008”/><ref>Meisenberg, Gerhard (2009). “Wealth, Intelligence, Politics and Global Fertility Differentials”. Journal of Biosocial Science 41 (04): 519. http://dx.doi.org/10.1017/S0021932009003344</ref>

One objection is that such differences in fertility would not result in a progressive decline in IQ, but only a somewhat lower average population IQ, after which a new steady-state equilibrium is argued to be established.<ref name=“Cambell”>

</ref> However, this has been argued to depend on assumptions which are unlikely to be true, being contrary to basic evolutionary principles, and being contrary to the results from centuries of selective breeding.<ref>

Causes: Migration

A 2009 study argued that for many countries, the effect of fertility on genotypic IQ is currently overshadowed by much larger effects, due to selective mass migration of groups with varying average IQs.<ref>National IQ Means Transformed from Programme for International Student Assessment (PISA) Scores, and their Underlying Gene Frequencies, Volkmar Weiss, The Journal of Social, Political and Economic Studies 1.34(2009): pp. 71–94</ref>

Causes: Other explanations

Other explanations include increasing accumulation across generations of mutations harmful to IQ and which are no longer removed by mechanisms such as high child mortality. Increasing age of fathers may increase the prevalence of mutations harmful to IQ in sperm. Another possibility is increasing prevalence of environmental pollutants, which could be harmful to IQ and in particular during childhood as the brain develops.<ref name=ds>Michael A.

The Flynn effect

Such dysgenic declines may seem contrary to the Flynn effect, which refers to the (earlier) observed increase in IQ scores over time. However, Flynn effect refers to an (earlier) increase in measured (phenotypic) IQ and not genetic (genotypic) IQ. The Flynn effect has been attributed to environmental factors, such as improved nutrition or simply improved test taking skills. It is argued that the relatively slow dysgenic decline in genotypic IQ has (earlier) been hidden by the gains, or apparent gains, from such environmental factors.<ref name=“LynnHarvey2008”/><ref name=“RushtonJensen2010”>

From the mid-1970s, there has been somewhat conflicting evidence on whether the Flynn effect have been continuing or whether it have gone into reverse in developed countries. Continued increases have been reported in studies the United States and some studies in Britain. Contrary to these results, studies finding that IQs have declined in recent decades have been reported in Norway, Denmark, Australia, the Netherlands, Sweden, Finland, France, and some studies in Britain. Various explanations for this has been proposed, including dysgenic fertility and immigration by lower average IQ groups. This latter conclusion has been argued to be supported by a study in Denmark, which found that the IQ of non-European immigrants military conscripts testing was 86.3, relative to 100 for indigenous Danes. French measured average IQ declined by 3.8 points during the 1999–2008/9 period, with this primarily argued to have genetic causes.<ref name=France1>Edward Dutton, Richard Lynn. (2015).

A 2017 study stated that average IQ levels were falling in Scandinavian countries. The IQ of Norwegians had been increasing since 1950 until a turning point around 1995. An annual reduction of IQ by 0.21 percent on average has been measured in Norwegians since that year, equivalent to a 6.5 percent decrease between generations.<ref>Intelligence of Norwegians and Danes on the wane, say researchers https://www.thelocal.no/20171228/intelligence-of-norwegians-and-danes-on-the-wane-say-researchers</ref> Losses in Nordic nations after 1995 averaged at 6.85 IQ points, when projected over thirty years. The situation in other countries varied. Some developed countries showed increasing scores. Generally, the study argued that the largest IQ losses may be at high IQ levels, but may be accompanied by lower losses or even increases at low IQ levels.<ref>IQ decline and Piaget: Does the rot start at the top? https://www.sciencedirect.com/science/article/pii/S0160289617302787</ref>

Declining innovation rates

The peak of the per person numbers of significant innovations in science and technology and the peak of the per person numbers of scientific geniuses have been argued to have been clearly situated in the Victorian era, after which there has been a decline. A 2012 study argued that ”This finding indicates that the Flynn effect, whilst associated with developmental indicators and wealth, only minimally influences innovation rates, which appear instead to be most strongly promoted or inhibited by changes in genotypic intelligence.“<ref>Murray, C.

"Spiteful” mutations

Pessimism regarding the future of Western civilization

Lynn in 2007 stated that he was pessimistic regarding the future of Western societies, in particular due to the dysgenic effects of the large scale mass immigration to Western countries. Before the end of 21th century White populations will become minorities in their own countries, if current trends continue. ”Yet this huge demographic catastrophe has been barely noticed by the media, and anyone who mentions it is considered as a “far right racist”.“ He even went as far as stating that ”I believe the best hope for the future of civilization lies with the Chinese and Japanese. They have not been infected with the virus of Political Correctness, and they are not admitting large numbers of immigrants. They have low fertility but this is not too much of a problem for the present and can probably be corrected in the future by paying people to have children. These are highly intelligent peoples and will probably carry the torch of civilization when it is extinguished in the United States, Canada, and Europe.“<ref>Race, Dysgenics, and the Survival of the West.

The IQ researcher Helmuth Nyborg wrote in 2012 that ”The bleak situation is characteristic of the rest of Europe too, perhaps with Eastern Europe as an exception. […] Ethnic Europeans will soon be wiped out of their own countries by this ever-expanding colossal demographic transition. Their national average IQs go down in the process, and when an average national IQ of 90 is reached, down go also their democracies and welfare. This also happens to European-Americans in the US. […] To sum up, not only Denmark but Europe and the US get dumber by internal dysgenic decay and by northbound mass-immigration. This will have catastrophic consequences for Western democracy and welfare, but non-Western countries will also suffer. Unfortunately, most ruling (left- or right-oriented) Western leaders are not only seriously misguided by the illusion of equality but also blatantly ignorant of biological realities, so they can’t see the elephant in the room. They eventually will, but that will be beyond the point of no return.“<ref>Helmuth Nyborg. Western countries get dumber by the day. 21 September 2012.

The IQ researchers Edward Dutton and Michael A. Woodley of Menie wrote in 2018 that in the not-so-distant future ”we won’t be able to safely fly aeroplanes, or maintain a lavish system of social security, or keep the electricity on all of the time, or maintain law and order everywhere, or organise democratic government or have widespread use of the internet. Life is going to become more harsh, more dangerous, and simpler. To give an obvious example, many houses are now entirely reliant on electricity: no fireplace, no gas. What are these people supposed to do when electricity becomes unreliable? Many people now commute into London from 70 miles away or even more. How are they going to get work as trains become more and more sporadic? They need to live closer to work, just as we all once did. If we start planning for this—rather than kid ourselves that “things can only get better”—then things will run far more smoothly when the time comes.“<ref name=raowe/>
