Why does India have an average IQ of 81?

[Anonymous No.11085600]

Because they are Indian

[Anonymous No.11085603]

Because most are low caste street shitters.

They actually have an average IQ of 162

Lack of education

[Anonymous No.11085625]

To properly assess IQ of different ethnic groups, one has to make sure that they grow up in similar environments.

Why is this relevant when IQ is primarily hereditary in nature? Because like any other trait, IQ can and often is severly suppressed in an unfavorable environment like India where malnutrition and disease run rampant. IQ is similar to height.
-Unfavorable conditions make people fail at approaching their genetical ceiling.
-The distribution of IQ values like height measurements can be approximated by a Gaussian curve.
-The genetical ceiling is absolute rather than relative. It is not possible to increase a fixed genetical ceiling without resorting to methods of biological or genetical enhancement. One can increase the height of a person despite his genetical ceiling by giving him growth hormones. No such things are currently known for IQ however.

In general, Indians and Pakistanis living in UK grow up in an environment where they are able to approach their genetical ceiling. Their IQ results are definitely more representative of what Indians could perform in an environment where their IQ isn't repressed.

Most Indian children are anemic and get infected with a severe disease every week. Plus an education that emphasises on memorization instead of understanding which causes de-stimulation of the brain.

All of these environmental factors then create shit genes.

Because there are a bunch of different ethnic groups in the country, Indo-Aryan populations tend to have much higher IQs than the national average.

Genes are inherited, not created. The interact between genotype and enviroment is called phenotype, the expression of those inherited genes. Dumbass.

Mutation doesn't entirely change your inherited genotype, you fuckwad. Unless you are massively irradiated, and die, which would be more likely to denature all of your shit and fuck you up anyway.

Radiation causes DNA damage, NOT mutations. A mutation is a change in the nucleic acid sequence that can be replicated; hence, a mutation can be inherited from one generation to the next. Damage can occur from chemical addition (adduct), or structural disruption to a base of DNA (creating an abnormal nucleotide or nucleotide fragment), or a break in one or both DNA strands.

>https://en.wikipedia.org/wiki/Mutation#Induced_mutation
>Radiation
>Ultraviolet light (UV) (non-ionizing radiation). Two nucleotide bases in DNA—cytosine and thymine—are most vulnerable to radiation that can change their properties. UV light can induce adjacent pyrimidine bases in a DNA strand to become covalently joined as a pyrimidine dimer. UV radiation, in particular longer-wave UVA, can also cause oxidative damage to DNA.[54]
>Ionizing radiation. Exposure to ionizing radiation, such as gamma radiation, can result in mutation, possibly resulting in cancer or death.
Suck my ass.

Oh, I typo'd missing out "damage". Gosh, that's totally worse than totally ignoring the fact that radiation can cause viable mutations.

So you do admit that shit environmental factors can create shit genes when a population is exposed to it for centuries?

[Anonymous No.11085796]

>>11085782
With a large caveat.
Say, the sudden increase in quality of living, worldwide. Yet, populations who haven't had time yet to genetically adapt, yet still show higher IQs.
For instance, the vast majority of Westerners still lived in Third World-esque abject poverty until the late 19th century, early 20th century.

They were still serfs, just better-off serfs. The Renaissance is a thing, a 300-year long thing.

[Anonymous No.11085873]

>>11085860
Yes, but that didn't drastically improve the qaulity of living more than the Industrial Revolution or formal schooling reform did, which happened in the 1800s, and 1900s, as I said.

[Anonymous No.11085894]

>>11085873
Yeah, but the Renaissance was a stepping stone, and then the Industrial Revolution itself was a 100+ year transition. The transitions happen much faster in modern times, going straight from 14th century Europe to Industrial Revolution in a matter of decades.

unironically feminism alas
this is one reason why we have dysgenic birth rates...

[Anonymous No.11086234]

>>11085894
Yes, that's exactly what I mean. So that it's impact upon epigenetic inheritance would be negligible, and doesn't explain the sudden increase.
Also, it should be noted, that phenotype can only express what genes already are present within the genotype (and mutations).
Phenotype doesn't express something that isn't within the genetic material that it is transcripted from.

[Anonymous No.11086237]

And to clarify, as we've already explored, biological evolution is a slow cumulative process of viable mutation, that may or may not be beneficial.
Therefore, it wouldn't be enough to explain the change already witnessed within the past century or so.
