Eugenics: Counter Argument to Inbreeding causing low IQ

[Papewaio]

Yes inbreeding can cause a raft of genetic problems, but it does not automatically cause IQ decreases. Environmental pressures cause the selection of traits to occur. Inbreeding just speeds up the visibility of recessive characteristics that wouldn't be triggered as easy if the genes weren't paired recessives.

There are well studied groups of limited gene pools and they don't automatically have low IQ as some recessive traits can be positive. The main group to consider in this possibly have the highest IQ of any ethnic group the Ashkenazi who dominate a lot of highly intellectual areas whilst showing a very high rate of genetic disorders.

As a side note EQ =/= IQ

Some of the loveliest people have extra chromosomes causing them to have limited intellectual capacity. On the other hand science types can be very socially inept. Autism is higher in children whose parents are both mathmaticians. Autistic kids can be described as geniuses who have very low social skills.

So inbreeding does not automatically equal low IQ does not automatically equal low EQ.

A much closer line of regression to having a violent future is having a violent past.

Nature and nurture are both responsible.

Nature:
inbreeding, toxins in utero (carbon monoxide, alcohol. narcotics, hypoxia etc)

Nurture:
Large number of siblings
Malnutrition
Lack of stimulation
Poor / abusive parenting

Inbreeding does increase the odds ratio of sub-par IQ. Nature is very keen on Eugenics. In small populations there will be an increased rate of child deaths of those who have "bad" recessive genes. These days we don't do this, so these genes are much more likely to be propagated.

EQ - is that emotional quotient? Most autistic children have low IQs and EQs. There are a small number of high functioning autistics who are probably more like savants than geniuses.

Violence screws everyone up in almost all levels.

Oh, Article - inbreeding does cause lower IQ.

[CrossLOPER]

The number of savants found in autistic populations is about 1 in 2000, and those tend to have less than useful "specializations". There are actual specific types of retardation where the afflicted person has a very positive disposition, as well as significantly diminished mental capacities. There are a number of different factors that contribute to retardation, inbreeding is indeed one of them. I would pause before calling those who are socially inept "retarded".

in strict mendelian probability, in the long run, before, I said again, BEFORE modern era, actually inbredding will increase the advantageous genes instead
since the individuals who inherit lethal/disadvantageous gene will simply dead sooner than later

to lesser degree, we can see this on dog pedigree

[Seamus Fermanagh]

Yes; like this may well work.

[Cute Wolf]

Yes; like this may well work.

of course, if we're heartless enough to simply terminate every embryo with genetic defects, while practicing inbreedings, the surviving human offsprings will have greater proportion of advantageous genes.

It does redruce IQ, it really really does

[Tellos Athenaios]

of course, if we're heartless enough to simply terminate every embryo with genetic defects, while practicing inbreedings, the surviving human offsprings will have greater proportion of advantageous genes.

To a degree, because the risk you take with monoculture is wipe out.
