UK arrested Tommy Robinson for reporting child-rape gangs that the government caters to. The UK banned reporting of his arrest, denied him a lawyer, and is trying to have him assassinated in prison. Regardless of how you feel about his views, this is a totalitarian government.

Tommy Robinson isn't the first to that the UK has jailed after a secret trial. Melanie Shaw tried to expose child abuse in a Nottinghamshire kids home -- it wasn't foreigners doing the molesting, but many members of the UK's parliament. The government kidnapped her child and permanently took it away. Police from 3 forces have treated her like a terrorist and themselves broken the law. Police even constantly come by to rob her phone and money. She was tried in a case so secret the court staff had no knowledge of it. Her lawyer, like Tommy's, wasn't present. She has been held for over 2 years in Peterborough Prison. read, read

Dysgenics

From en-Rightpedia
Jump to: navigation, search
The Childfree Life by Lauren Sandler in TIME magazine. The controlled media discourages healthy Europeans from reproducing, helping cause a lack of a eugenic population.

Dysgenics refers to a genetic deterioration of a population or populations and the study of such processes.[1][2][3] Much of the polemics in the alternative media against "eugenics" actually refers to dysgenics; eugenics is about lifting up the human stock, rather than degenerating it.

Etymology

Dysgenics was coined in 1915 for the genetic deterioration in modern human populations that eugenics aimed to correct.[1]

History

Mid-nineteenth century several scientists, including Charles Darwin, began to worry about and find empirical evidence that the genetic quality of Western nations was deteriorating. The earlier natural selection had been changed by processes such as 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 included marrying late due to the demands of a career. Another 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 become increasingly widespread and contributed to the rise of the eugenics movement. After World War II research and public discussion on dysgenics and eugenics increasingly become rejected and taboo subjects. Another trend after WWII is the mass immigration to white countries of people from races with different genetics and often an argued lower average genetic intelligence.[1]

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.[4] Another argument is that modern warfare may have had a dysgenic effect by the healthy selectively being drafted and killed whilst preserving the unfit at home.[5] However, such effects would be 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.[1]

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.[6]

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".[7]

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.[8] 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.[1] 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.[9]

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 have 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."[10]

Other studies have demonstrated the relationship between high IQ and low fertility in other developed countries.[1] Whether it is occurring in developing countries is unclear. A 2005 study of the Afro-Caribbean population of the Caribbean country Dominica found a weak such relationship.[11]

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.[12] A 2017 study found dysgenic effects on IQ also in Taiwan with the effect being stronger for younger adults.[13]

There are also studies which have argued that the world's genetic IQ is declining since countries with higher IQ have lower fertility than countries with lower IQ.[14]

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.[15] 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.[16][17][1]

Causes: Migration

A 2009 study argued that for many countries the effect of fertility on genetic IQ is currently overshadowed by much larger effects due to selective immigration and emigration of groups with varying average IQs.[18]

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.[19][20]

Declining average IQ results in Kuwait and Sudan have been proposed to have religion-inspired changes to the educational systems as one explanation.[21][22]

The Flynn effect

Such dysgenic declines may seem contrary to the Flynn effect which refers to the observed increase in IQ scores over time. However, this refer to an increase in measured (phenotypic) IQ and not genetic (genotypic) IQ. The Flynn effect have 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.[23][24][25][26][27]

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.[28][29]

A 2016 literature review stated that "In this study, we present a systematic literature review, conducted in order to discover in precisely how many countries this reverse phenomenon has been uncovered. Using strict criteria regarding quality of the sample and the study, we found nine studies reporting negative Flynn Effects in seven countries."[30]

See Race and intelligence: The genetics or not debate: The Flynn effect regarding possible causes of the Flynn effect, relation to the g factor, and argued implications for racial IQ differences.

Dysgenics and the fall of civilizations

Dysgenic processes has been argued to be an important cause of the decline and fall of many advanced historical civilizations such as that of ancient Greece and ancient Rome.[1]

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. The study also found that Arab countries today have lower IQ than countries with similar skin color in Southeast Asia despite often being much wealthier due to oil. This may support the recent dysgenics argument.[31]

Future trends

Lynn and Harvey (2008) suggested that designer babies may have an important counter-acting effect in the future. Initially this may be limited to wealthy couples, who may possibly travel abroad for the procedure if prohibited in their own country, and then gradually spread to increasingly larger groups. Alternatively, authoritarian states may decide to impose measures such as a licensing requirement for having a child, which would only be given to persons of a certain minimum intelligence. The Chinese one-child policy, although not having a stated eugenic purpose, is an example of how fertility can be regulated by authoritarian means.[23]

On the other hand, 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."[32]

Dysgenic effects in early societies

Dysgenic processes has been argued to be an important cause of the decline and fall of many advanced historical civilizations such as that of ancient Greece and ancient Rome.[1]

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.

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.[33]

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.[34][33]

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 been changed by processes such as 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 included marrying late due to the demands of a career. Another 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.[1]

After World War II research and public discussion on dysgenics and eugenics increasingly become 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.[1]

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.[35] Another argument is that modern warfare may have had a dysgenic effect by the healthy selectively being drafted and killed whilst preserving the unfit at home.[5] However, such effects would be 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.[1]

Health

Improved medical and social care may possibly lead to increased incidence 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.[36][37]

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.[38]

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.[34]

Personality

Those worried about dysgenics have considered traits such as self-discipline, good work motivation, energy, ambition, and strong moral sense that contribute or possibly contribute greatly to a person's achievements but in modern populations less to reproductive success than previously. A modern term for many of these traits is conscientiousness.[1]

Conscientiousness has a high heritability.[34]

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.[39]

Declining innovation rates

The height of the per capita numbers of significant innovations in science and technology and also the per capita numbers of scientific geniuses has been argued to have been clearly situated in the Victorian era; after which there was 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."[40][41][42]

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."[43]

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."[44]
