The total human capital of a nation I'd say is represented by the following equation: Average IQ x Population size = Total human capital.

Singaporeans are smarter than Italians on average but Italy has far more human capital and potential due to its much larger population. It's not enough to simply have a smart population, they must exist in sufficient numbers to achieve the scales essential to supply chains and industrialization.

However, the equation does come with some caveats. There is I'd say a negative human potential factor as well.

You can have an intelligent 5 million strong population with 105 IQ on average, but their ability to achieve feats is reduced if they are saddled with 50 million BNs. South Africa comes to mind.

The country has more NW Euros than Denmark but is vastly more corrupt, dirty, poor, and dysfunctional. The positive impact of the Boers and Anglos is swamped by the Bantu hordes.

India is the greatest example of this phenomenon. India by some accounts has over 100 million 110+ IQ Brahmins but it's still a very poor and undeveloped country. Why? Because the non-Brahmin Indian normies have an IQ of around 80 (AK estimates it to be 75). Thus, there is a general culture of corruption, nepotism, criminality, incompetence, and lower standards.

A country solely composed of 100 million brahmins would have more human potential compared to current India. It would have higher standards and a more functional cultural milieu.

So, I'd say, Human potential = (Number of high IQ pop * average IQ of said pop) - (Number of low IQ pop * average IQ of said pop)

I'm defining high IQ pop as pops that have an average IQ of over 95. I'm defining low IQ pop as pops that have an average IQ of below 85.

Below 85 iq, an army can't do anything with you, not even manual labor like moving apple crates. You're just too dumb to be of any use to anyone. Not only are you a total deadweight and burden on the productive classes, you are also prone to criminality, mental illness and other dysfunction.

That's why 10 million BN are far worse for a nation than 10 million Mexicans even though both are sub-90 iq populations. With that out of the way, here are my rankings:

1)China: 1.4 billion pop, 103-105 IQ and 92% Han Chinese. Chinese human potential is completely unmatched in the history of the world. The next ten countries on this list combined couldn't match Chinese net potential. Few minorities like Manchus and Mongols who are high IQ as well.

2) United States: 323 million pop. 190 million whites mostly Northwest Euro. The average IQ of NW euros is around 102. 8.3 million Jews and the average IQ is around 107. 10 million or so "Asians'' mostly comprised of highly educated immigrants from India and East Asia.

They are subtracted by 40+ million BN and some 80 million Hispanics. Hispanics are in quotes because there is a sizeable Castizo component.

3)Japan: 123 million people, 99% Japanese, and an average IQ of 105. No subtracting factor.

4)Russia: 146 million people. Over 85% East Slavic who have an IQ of around 100. About 4% Volga Tatars who have a similar IQ.

An advantage Russia has is that they don't have extremely criminal or deranged minorities like BN or Arabs. Most of their minorities are "usable so to speak."

5)Germany: 82 million people. Only around 80% are Ethnic Germans who are some of the most innovative and productive people on Earth. Another 10% are European immigrants. However, they are subtracted by the negative provided by massive numbers of Turks and Syrians.

6)South Korea: 51 million people. Almost 100% Korean and has an average IQ of 105. No subtracting factor.

7) Britain: 67 million people. Around 78% are white British, arguably the most productive people in human history. Around 7% are white British. 3% Hindus or Chinese. However, there is a heavy subtracting factor in the form of a huge number of subcontinental Muslims, Arabs, and Blacks.

1. Italy: 60 million people. 91% white with an average IQ of around 100. Southern Italy is a somewhat low IQ but it's counteracted by the more numerous North Italians who are very intelligent.

Other whites are around 4%, mostly Romanians, Poles, and other Eastern Euros. The remaining 5% has negroes and Arabs.

A significant but not serious subtracting factor.

9)France: 65 million people. Historically a scientific and cultural giant. However, France today is likely below 80% white, and ethnic French men are likely below 70%.

The remaining 20% is composed of the worst of the worst. Over 5 million BN and 8 million inbred Maghrebis. Ethnic Frenchmen are smarter than Italians but are dragged down by a massive subtracting factor.

10)India: As mentioned earlier. A huge high IQ fraction in the form of +100 million Brahmins with an average IQ of 110 or more. However, they're swamped by 1.1 billion lower caste Indian masses who have an IQ of around 80.
