Dysgenics or cacogenics is theory. However in times past, Royalty practiced an extreme version of eugenics, which is in effect the opposite of dysgenics, via incestuous relationships.History shows how well that worked out. Nazis, then and now, subscribe to eugenics or racial hygiene.
WRONG HOMO!! You used far too little information in your search engine& ended up back at eugenics................ ....The word eugenics is used to describe the idea or practice of encouraging those people with desirable mental or physical traits to produce the most progeny. This is based on the assumption that traits like intelligence and character are, at least in part, genetically determined.
Eugenics had tended to go out of favour in the last fifty years or so. This was partly due to the misuse of eugenics by Nazi Germany. Even the idea that intelligence was an inherited trait was questioned by many academics and others.
More recently however a few individuals have begun to worry about dysgenics. Dysgenics refers to the problem of those with poor intelligence or character producing disproportionately more progeny. The result is a steady genetic deterioration in human populations.INTELLIGENCEAlthough the problem of dysgenics is found with a number of human characteristics, probably the most important and widely studied is intelligence. Most of this discussion will therefore deal with intelligence.
An individuals score on a test of intelligence (also referred to as cognitive ability) is a good indicator of their likelihood of success in academic or vocational pursuits. Scores on intelligence tests are often referred to as an individual's intelligence quotient or IQ. Generally the higher people progress academically the higher their IQ.
The first book on intelligence and hereditary was written by Francis Galton and came out in 1869. The book was called 'Hereditary Genius'. Since then the question of the heritability of intelligence has been one for heated debate. The debate becomes more heated when the source of differences in intelligence between different racial groups is considered.
RACIAL DIFFERENCESThe nature or nurture argument is most heated when racial differences are discussed.
Most of the research done in this area concerns the differences in average scores between blacks and whites in the United States. That research shows that blacks tend to score on average about 15 IQ points below the white average. Hispanics and American Indians score averages somewhere between the black and white averages. People of Korean and Japanese descent score slightly higher averages than whites.
The difference in IQ between blacks and whites is evident in children as young as 3 or 4, and remains fairly constant afterwards. The difference is not caused by schooling and schooling does not increase or decrease it.
ImmigrationImmigration was cited by Herrnstein and Murray as a possible source of genetic deterioration in the American population. The problem is probably more relevant to Australia with our proportionately larger immigration intake.
It is possible that the intelligence levels of those from North East Asia are as high, or even higher than those of white Australians. However it is likely that as living standards in the region reach a similar level to those of Australia we will attract fewer migrants from there. Instead we are likely to attract migrants from the more backward areas, where the populations are most likely to have lower average intelligence. Hence immigration will be dysgenic in the future.
In fact there is evidence that the migrant groups in this country with the largest family size also have the highest unemployment levels. Dysgenic problems coming from immigration may have already started.
Relying on Richard Lynn’s work Dysgenics: Genetic Deterioration in Modern Populations, the relaxation of internal selection is thought to have begun around 1850 as the fertility of the lower classes exceeded the upper classes because of improvements in hygiene and reduction in diseases. He cites Lynn’s estimate that England lost 6.9 IQ points over 90 years (1920-2010) and estimates that Denmark’s average IQ dropped around 10 points since 1850 due to internal relaxation of natural selection.
Nyborg’s latest paper charts past trends and projects IQ changes in Denmark as a result of two trends: relaxation of natural selection among the traditional Danes, and an influx of low-IQ immigrants. These two trends together amount to what he terms a “double relaxation of natural selection” (DRNS).
