To much heat makes your iq 76

The closer your ancestors lived to this line 60,000 years ago the dumber they are today.

Why???

60,000 years of white flight

Austrália is as far as china from the line.
"Abos iq = Chinese iq"? I guess you are the line op

it only counts for humans

Difficult to build a flourishing civilization there.
I mean, there WERE, but the tropic of Cancer is where the real parties are at.

Not even remotely true, it’s more that cold climate agriculture selects for future based planning and higher IQ. Natives of northern Canada are dumb as bricks so are most nomadic peoples. This is why East Asians and Europeans have higher iqs generally speaking. They had to plan ahead to survive harsh winters rather than simply following prey animals for hunting

warm weather makes for easy survival, that's why all the dumbasses live in florida.

>To much heat makes your iq 76
Because you never have to select for intelligent people to delay gratification, ration food, be cooperative etc throughout the winter months.
When food is plentiful year-round, you don't have that crucible of selection. Having to hunt and defend from larger animals may have selected for more physical strength and stamina over generations.

These guys are right, but people who live in permanent cold aren't very smart either, as they don't need to really plan anything between the warm and cold seasons, since there are none

The environment probably actually promotes impulsiveness in genetic behavior because when you see that meal walking by, you go run after it immediately, or scrounge up every fruit you see lickedy split

Same reason computers run faster with better cooling fans.

(Your brain is a computer.)

>your face when you realize native Americans And Mexicans separated from Koreans 40,000 years ago. This might explain the aztecs.

Women wear less clothes the closer to the equator. Men distracted by this. Degeneracy ensues.

The same trend as seen in the usa

>Why???
why would you need a fire in a tepid night? why would you need anything other than a roof in a rainy winter? the winds of winter forced the white man to build walls and the walls left him alone with nothing to do but study his fire

See bottom half- this is based solely on ethnicity

So you're saying it's the combination of cold plus agriculture, and that's why cold-weather hunter/gatherers aren't as intelligent?

Pretty much. If it is hot all of the time or cold all of the time nature doesn't select for being able to plan ahead. In temperate areas with harsh winters anyone who didn't plan ahead would starve off or be too weak to be appealing as a mate.

Cold climate cools down your brain and make it work more efficiently.

Cold weather requires more problem solving in order to survive. Also the plants and animals in the area were easier to domesticate, so proper nutrition over the years mixed with the need to use the brain for survival lead to more advanced cognition.

Easier to live/Less harsh environment

Nigerian IQ and the Sierria Leone IQ are okay. 86-91 average. Btw African Christian countries have IQ unlike Muslim countries.

today, my ancestors who lived 60,000 years ago are dumber?

What about people that live in arid climates and built irrigation systems a la Mesopotamia/Egypt/Persia

>Cold weather requires more problem solving in order to survive.
Then why do the various native arctic people all have 80-90 average IQ's?

Higher than Africans but lower than Europeans and East Asians who had plants and animals that were easier to domesticate.

Yet they had much more advanced civilizations than farmers of Central Europe for thousands of years

Romans and Greeks also were advanced and from warm Mediterranean or semi-arid climate

Winters are short and less cold, summers milf and warm

60,000 years ago, Europeans and Middle Easterners had not genetically differentiated from the ancestors of (East Asians + Papuans/Australian aborigines – contra pol retardation, aborigines are not some special early branch of humanity but quite clearly related to East Asians and Amerindians, and more closely related to Europeans than to any Africans or archaic hominins)

Polygenic IQ scores are about the same in Sakha and Japanese. agriculture really doesn’t explain anything, it’s stupid whiggish thinking that if anything valorizes the force responsible for making people physically puny, compliant, small-brained, small-framed, uncreative, but numerous, quick to burgeon into disgusting swarms

Medieval Novgorodian republic in northern Russia was a democracy with high literacy rate even among peasants while Moscow principality at the south was a tyranny.
Seems legit.

natural selection mutt plebe - only the smartest resourceful monkeys could survive in colder climes this system coupled with the natural abundance along that line that leads to constant invasions which select for big dumb apes

For thousands of years of course. they settled sooner and started. lets take a look at the time between settling and advancements.

of course genetics play a factor as well. the Neanderthal DNA lead to hight maximum evolution capacity of European brains. Then take a look back at history and you can see that picking correct cultural choices also play a factor in human mental development.

Fix your filename, the (2) ruins it.

You've never heard the story of the ant and the grasshopper?

Kinda makes me suspect you're sub-human tbqh

Explains the dixie and Texan mentality

>Australia
checks out

stfu please

too much sun burns your brain

You have to plan for drought periods.
Africa is tropical.
Arabia is always desert with some oasis and coastal cities.
Mesopotamia and what's now Turkey and Iran has more climate variance.
