Not the other guy, but education/exposure to experience is a key factor along with genetics disposition in determining IQ.

The world wasn't always a literate one. The Asian countries particularly only managed high literacy rates in the last few decades while the western countries enjoyed it for about a 100 year or so. The so called "flynn effect" is just the world catching up in literacy rate. Africa/India will experience major literacy growth in the next few decades.

>Staying warm and finding food in colder, sparser climates takes smarts

exactly, from evolutionary stand point "caucasoids" are smarter because they had to survive very difficult climate/conditions, meanwhile inhabitans of tropical climate/conditions had it comparatively more easy so they didn't have the evolutionary preassure for higher intelligence to help them survive.

this also goes in line with the out of africa theory, the people that left africa went through evolutionary preassure to develope higher intelligence in order to survive difficult climate/conditions.

this is also why racemixing could by considered a bad thing from evolutionary stand point, you are basically regresing all that time that it took nature to adapt the people that got out of africa to higher intelligence.

WhatTheFuckIsWinter.jpg

[Anonymous No.10781549]

Contrary to popular belief, harsh environments select for brawn and comfy environments select for brains. Why? Because in harsh environments you are constantly in survival mode. No time to rest and think about anything.
>must secure food
>must secure water
>must secure shelter
>must secure food
>must secure water
>must secure shelter
>....
All the time.

In comfy environments you have more leisure time, and this allows humans to think, be creative and come up with ways to make their life even easier than it already is. For example, they can spend the time digging a canal to divert the river so that next day they don't have to carry the water in a pail, they can just let it flow to them.
And then next time they have some leisurely time, they can weave a basket to collect and carry food more effectively.

If you ever played any AOE style strategy game you understand that time is the most important resource you can have, and if you have time, you can advance your civilization and become more efficient and have even more time, but if you cannot spare any time, you are stuck in a loop of inefficient scrambling for survival.

Evolutionary neuroscience student here

This is entirely my own theory, but I believe that humans still haven't evolved enough to physically and mentally deal with temporal/polar climates. The necessities for our well-being in these climates (whether it was hominins 1 million years ago, humans around the paleolithic revolution 40k years ago or humans now) are much higher than in climate zones we are physically and mentally adapted to.

So, there is a predisposition for humans to survive that manage to offset these difficulties and over time, this gives rise to a more mental/culture based kind of human than a human who doesn't need additional tools/lifestyles/mental phenomena to deal with an environment he is already well-adapted to.

Evolution will tend to select for high IQ in these climate zones, simply because the benefits it brings are required to function adequately as an individual, as a community and as a species.

But, that's my theory and I haven't seen anything like this voiced in any scientific texts because obviously ideas like these don't make it past the peer reviews.

People at higher latitudes have more Ashkenazi genes in their population which are the genes allowing for high IQ.

https://en.wikipedia.org/wiki/Ashkenazi_Jewish_intelligence

How high the IQ of a civilization is is dependent on how much Jewish genes they have. East Asians for example have the highest amount of Jewish genes outside of Jewish people and thus they have the 2nd highest IQ behind Jews.

Caucasians are after that and have the 3rd highest IQs behind Jews and East Asians.

https://en.wikipedia.org/wiki/Kaifeng_Jews
https://en.wikipedia.org/wiki/Japanese-Jewish_common_ancestry_theory

Basically there are hypothesis out there that Jewish people were the original humans that evolved consciousness and the "thinking genes" and that they slowly spread it out but not everywhere equally. Asia and caucasians got most of the genes and Ashkenazi Jewish people have the highest concentration of them.

This also explains why 54% of global PhDs belong to Jewish people and 40% of all scientific Nobel prices were awarded to Jews despite them being only 0.006% of the global population. It's because they have the purest form of the original "intelligence genes"

US occupation of Dominican Republic:
>The military government established by the U.S., led by Vice Admiral Harry Shepard Knapp, was widely repudiated by the Dominicans, with many factions within the country leading guerrilla campaigns against U.S. forces.[88] The occupation regime kept most Dominican laws and institutions and largely pacified the general population. The occupying government also revived the Dominican economy, reduced the nation's debt, built a road network that at last interconnected all regions of the country, and created a professional National Guard to replace the warring partisan units.

US occupation of Haiti:
>Within days, the Marines had taken control of the capital city and its banks and customs house, which controlled all the finances of the island nation. The Marines declared martial law and severely censored the press. Within weeks, a new pro-U.S. Haitian president, Philippe Sudré Dartiguenave, was installed and a new constitution written that was favorable to the interests of the United States.

Caucasian and East Asian migrant human populations suffered severe bottlenecks from the perils of neolithic living in cold climes. Due to the founder effect you only have the most intelligent (and forward thinking) strains making the cut, and inbreeding exacerbates this effect. Without that pressure, even populations that were formerly hardened and sharp can start diluting IQ, such as in Central America.

[Anonymous No.10781881]

>>10781870
This also explains why Jews have the highest IQ. There have been 44 genocide events against Jews throughout history. Every time only the most intelligent survived which then started inbreeding again. Causing all modern scientists to be Jewish.

Intelligence test scores and educational duration are positively correlated. This correlation could be interpreted in two ways: Students with greater propensity for intelligence go on to complete more education, or a longer education increases intelligence. We meta-analyzed three categories of quasiexperimental studies of educational effects on intelligence: those estimating education-intelligence associations after controlling for earlier intelligence, those using compulsory schooling policy changes as instrumental variables, and those using regression-discontinuity designs on school-entry age cutoffs. Across 142 effect sizes from 42 data sets involving over 600,000 participants, we found consistent evidence for beneficial effects of education on cognitive abilities of approximately 1 to 5 IQ points for an additional year of education. Moderator analyses indicated that the effects persisted across the life span and were present on all broad categories of cognitive ability studied. Education appears to be the most consistent, robust, and durable method yet to be identified for raising intelligence.

"Winter" is actually a really obvious and relatively common explanation of some difference in IQ, in the places that accept such a thing.

A good example is Japan. They have the three snowiest cities in the world (though not coldest, obviously), limited building space, but relatively consistent weather.

Somewhat related, a study that got controversy showed that geographic barriers had the highest correlations to peace, even beyond groups that developed from the same people historically, versus culture, food, technology, even religion.

Predictability, security, and common social goals are likely the biggest factors in whether or not a civilization and intelligent people developed somewhere. Without predictable weather you can't sustain food or food development, without security you can't develop cities and specialized workers, and without common social needs a government would inherently trend towards oppression and power struggles, especially exasperated by shifting resources and unreliable populations.

>>10785044
There's a lot of factors that come into it. The most obvious would be A) predictable pressures and B) security to specialize. Part of the reason cold itself could be a significant factor is it's more difficult to do things period in the cold. It sort of acts like an artificial reducer of crime and impedes people traveling. If an area had to relatively stable regions, we could expect the one that had more winter weather to be able to produce better people and cities, because they could concentrate, try to innovate to reduce the problems caused by cold weather, and reduce crimes by making it harder to get around.

Might make some sense as technology changes things. Crime has been growing in Japan, aided by reduced travel penalties and reduced need for social cohesion to survive. Conversely a number of African countries are booming like crazy, because technology permits a wide government, supported by agricultural improvements (irrigation, more productive crops) and presently lower population density (Ethiopia has a lot of home-owned farms for example).

True, a threat should promote improvement, but we'd have to look at the circumstances: 1) it's likely by people with the same resources as you (warmer weather should increase travel and dissemination of what's available), 2) the people have a head-start, since they know of their situation before you do (though maybe not for long), and 3) if the disruptions are within a generation, then everyone gets affected proportionally, and it would be difficult to sustain skills, resources, and accomplishments over generations

Basically repeated attacks at the bottom would force a larger proportion of the population to be stuck in a subsistence state. The only way out would be a government that could ration things among those who had and had not, but historically, we see a lot more power grabbing than social benevolence. It might be more interesting to try and determine why this cycle isn't broken in warmer climates.

IQ test's aren't a flawless measure of intelligence. People with worse education will give a lower IQ score. People in poorer countries have worse education, and so score worse on IQ tests.

Not so. IQ isn't deterministic per se (as in you can't say "this guy will do better with his 120 IQ than this guy with his 105 IQ"), but it is useful on a population-wide level. General intelligence correlates strongly with all sorts of positive metrics and as any given society is driven by its top 5-10% (believe it or not most people anywhere are pretty much just useless laborers and followers), a difference between 100 and 85 IQ average can mean MASSIVE differences in the accomplishments of its tail enders (there would be like 5x more people with an IQ of 125 in the society with the 100 avg, all other things equal).

Its not the coldness itself, rather it is the variation of seasons. Look at Eskimos as an example of populations who almost perpetually live in the cold. Their IQ is in the 80s to 90s range, much lower than Europeans and Han Chinese. The reason why the latter 2 groups have a higher average IQ is because while the cold may lead to selection for larger brains, it will not in of itself lead to selection for more efficient neural architecture, for that you need considerable variation and long term planning as seen in societies which have to deal with agriculture and at least one season where it will not be possible..

...people didn't always exist. Life had to evolve there. Your own example of burying meat is REALLY counter-intuitive, and in places with more food or warm winters wouldn't need or be able to take advantage of it.

Not everybody, nor would everybody be able to figure out consistent solutions, which is the point. Take something dumb like seafaring. For nations that wanted to travel for months at a time, a lot of people died of scurvy before they figured out you need to bring citrus. A society which was dumber, or didn't have the opportunity to look into why would've been at a big disadvantage. Geographically speaking, some places probably don't have good sources of vitamin C, so even if they found certain foods needed to be eaten, they might not have been effectively able to transport them for long periods. (in places that lack cows, there's often people that eat dirt, because it has enough calcium for them to grow healthier children).
