Why the high intelligence of Indian Americans?

I reproduce below a well-informed answer to the above question.  I disagree with his conclusion that it is all due to nutrition however.  Other work finds only 5 IQ points attributable to nutrition.  The suggestion of 15 IQ points is therefore startling.  So I think we need to look at other possibilities.  I think that the Indian advantage is probably a compound of several factors.

The treatment of Indians as a single group is of course absurd.  Almost any Indian will regale you with stories about the great gaps between the castes.  And the castes do seem to have a racial and historic origin.  A Brahman and a Dalit are worlds apart in all sorts of ways, including skin color. And it is usually held that the differences arose from the Northern  Brahmins being in fact late "Aryan" invaders on top of an original Dravidian population.  So we would expect Brahmins to have higher IQs.  And Brahmins seem well-represented in Indian immigrants to America.

Everything in the above paragraph is however subject to controversy so how much caste accounts for higher IQs in Indian Americans remains "under study".  Something that would reveal the effect (or not) of caste would be a study of Indian diaspora populations in places such as Fiji, where the Indians there are the descendants of coolies imported to act as agricultural labourers.  If they have high IQs, there is no caste effect.  But I can find no data on such populations.  It is however true that Indians run just about everything in Fiji these days.

The next possibility is related to the one above:  A general selective effect of immigration.  Diaspora populations are not always brighter than the home population but when we are looking at poor countries they probably are.  To get yourself out of a poor country to a rich one surely requires brains.  So regardless of caste, diaspora Indians should be brighter.

The third possibility is one shown up by the Flynn effect:  Education.  Education does have an effect on at least some measures of intelligence.  How that works is speculative but the most plausible explanation is that doing tests and exams in the course of a long education develops test-taking skills (e.g. guessing when uncertain) that generalize to IQ tests. And the Indian education system is woeful so a transition to the less woeful U.S. system should confer an advantage.

A fourth factor that is rarely mentioned in these discussions is regional differences within India.  The Indian South seems to be much brighter, particularly where mathematical ability is concerned. The great concentration of Indian IT knowledge is in Bengaluru (Bangalore), which is in the South.  And it was almost entirely Southern engineers who were behind the quite remarkable Indian Mars shot.

I am not going to say much about why the Southerners are smarter but I note that they hate one-another.  Keralans despise Tamils, for instance.  And that is related to the long history of warfare between them.  And dummies are the least likely to survive wars.  So warfare has dragged up the average IQ of most of the South.

But getting back to Indians in America:  I have seen no figures on it but I gather that a huge proportion of Indians came to America to work in IT.  If that is so, they would mostly have come from the South -- because that is where the IT ability is.  So the Indian immigrants to the USA came from a (Southern) population that was ALREADY pretty high on IQ.  So from that starting point, the various advantages (already mentioned) of life in the USA could easily have added one third of a standard deviation -- which could explain what we see.  It could in fact explain the whole of what we see.

And regardless of where they come from in India, being employed to work in IT is a HUGE selective pressure.  To code easily in languages like C and its derivatives requires an IQ within about the top 2%. If that doesn't bring up the average, nothing would.

So I would summarize that the high IQs of Indians in the USA is the combined effect of nutrition, education, caste, an immigrant effect, an effect of regional origin and an effect of occupation.

Given the extraordinary difference in average IQ between Indians in India and Indians in America (well over one standard deviation) I think a multifactorial explanation has to be strongly indicated.  But all answers at this point are speculative.


One of the great mysteries in IQ research is why Indian Americans are such super achievers despite the fact that India reportedly has an IQ of only 82 according to the book IQ and Wealth of Nations.

And yet Indians in North America are known for their high intelligence and scholastic achievement, and despite being new to America, are already slightly over-represented on Forbes list of the 400 richest Americans. In some parts of Canada (particularly the maritime provinces like Newfoundland) if you’re Indian, all the white will people will assume you’re a doctor.

So how can Indians in North America be so smart when India’s average IQ is not great? Many people in the HBD-blogosphere invoke the theory that India is nation of many micro-races (castes) and that largely the smartest castes migrate to America, but the truth is usually much simpler.

Of the 2.8 million Indians in America, probably no more than 25% (700,000) are the ones who initially gained immigration (and the remaining 75% are the spouces, siblings, parents, and children, who came alone for the ride). But these 700,000 who actually gained immigration for themselves and their families are probably roughly the most occupationally successful 700,000 Indians out of a population of nearly 1.3 billion. In other words, they are above the +3.3 standard deviation mark in occupational status, and are on on average +3.5 SD. Since occupational status (mostly a function of education and income) correlates 0.7 with IQ, we should expect their IQ’s to be 3.5(0.7) = 2.45 SD higher than the average Indian (assuming Indians have a mean IQ of 82 and an SD 15, those who initially gain immigration to America should have an IQ of 119).

But because the IQ correlation between a parent and his adult offspring is about 0.45, the children of these high achieving immigrants from India should regress precipitously to the Indian mean:

0.45(119 – 82) + 82 = 99

Thus we should expect second-generation Indians born in America to have IQ’s around the U.S. average which is inconsistent with their incredible achievements. Can their achievements thus be explained by Tiger Moms? According to excellent Jamaican American blogger JayMan, parenting has zero impact.

So how do we explain the high achievements of second generation Indian immigrants? Nutrition. Blogger Steve Sailer was perhaps the first to notice that even un-mixed black Americans who have lived in the United States for centuries are several inches taller and about 13 IQ points smarter than black Africans. This suggests that first world nutrition adds about 13 IQ points (and several inches of height) to people of third world ancestry.

Ditch Obamacare, and don't stop there

by Jeff Jacoby

TO HEAR the liberal denunciations of the proposed American Health Care Act — House Speaker Paul Ryan's plan to replace Obamacare — you would think the GOP had set out to wreck a brilliant and much-loved social reform that Americans couldn't imagine living without.

Democratic leaders in Congress have slammed the Republican legislation as a plan to "Make America Sick Again," and to wreak, in Nancy Pelosi's words, "massive damage to millions of families across the nation." The AARP, an influential pressure group that claims to represent older Americans, has launched a high-profile campaign against the bill on social media, by video, and in an open letter to lawmakers. AARP warns that the Republicans' health care overhaul "raises premiums and weakens Medicare" and would "dramatically increase health care costs for Americans aged 50-64."

Well, yes and no. The Ryan plan is indeed deeply flawed. Not because it obliterates Obamacare — but because it doesn't.

This is only the latest turn in a long saga of health care "reforms" that have constricted choice, disempowered consumers, banished price awareness, eliminated competition, and discouraged innovation. The results are all around us: skyrocketing medical costs, mounting economic pressures on employers, employees, doctors, and patients — and a political obsession with providing insurance, rather than with producing good health.

It would take a miracle for Congress to find the courage to pull up the whole misbegotten system by its roots. But the payoff would be even more miraculous.

From Day 1, Obamacare was relentlessly unpopular. Republicans surged to one political triumph after another by vowing to get rid of it. Some libertarians and free-market conservatives, to their credit, have spurned the leadership bill as nothing more than Obamacare Lite. But many weak-kneed GOP moderates have been spooked by the assault from liberals, especially after the Congressional Budget Office prediction that ending Obamacare would mean 24 million more people without health insurance. There is good reason to doubt the CBO's conclusions — its previous coverage estimates have routinely turned out wrong — but Democrats and their allies are flogging them with enthusiasm, raising alarums about the catastrophe to come if Obamacare is dismantled.

Yet many in the GOP are now waffling because they fear the political costs of doing anything else. They would like to get rid of the mandates, taxes, and regulations that the public has never liked, but can't bring themselves to scrap the law's popular benefits and entitlements. They don't want to be held accountable for not allowing young adults to stay on their parents' insurance plans until age 26. They don't want to face the outrage that will follow when insurers charge higher premiums to customers with pre-existing conditions.

"Republicans want medicine to be inexpensive and effective," commentator Mark Humphrey writes, "but they do not want to repeal the morass of regulations that make it expensive and ineffective.

Just so. But they can't have one without the other — and without braving the political storms that have made such chaos of America's health care and health insurance landscape.

If Republicans were serious, and willing to endure some political pain to reach a better outcome, they'd eliminate the tax deduction for employers who provide health insurance as part of employee compensation. They'd repeal laws that force insurers to cover a legislated array of medical benefits and treatments. They'd remove the barriers that restrict consumers in one state from purchasing health insurance across state lines.

And they'd break the destructive habit of treating health insurance as the logical and preferable way to pay for routine health care.

Were members of Congress to enact all that, they would be replacing a dysfunctional, expensive, and coercive environment with something vastly better: a robust, competitive market focused on the interests of consumers — not on the demands of the insurance cartel and the political class. They would be restoring the price transparency that has long been missing from health care. They would be encouraging medical providers and insurers to compete in earnest — which would inevitably lower prices and improve quality. They would be de-linking medical coverage from employment, and endowing tens of millions of Americans with the economic leverage that comes with choosing for themselves what policies they will buy and from whom. And they would be ending the crazy distortions caused by using health insurance to pay for regular, ordinary expenses — something we would never think of doing with automobile or homeowner's insurance.

Instead of solving the system's problems, Obamacare only entrenched them. While Democrats portray repeal of the Affordable Care Act as an assault on baseball, hot dogs, apple pie, and Chevrolet, Republicans ought to be reminding voters how Obamacare played out in real life: reminding them, for instance, that it hurt more families than it helped. That it saddled insurers with losses so massive they were forced to pull out of many state exchanges. That it forced millions of Americans off their existing health plans. That it fueled double-digit annual increases in premiums. That it added billions to the national debt.

Since 2010, Republicans have been swearing up and down that they would scrap Obamacare. The way to do that is to scrap Obamacare.

Scrap the subsidies, the community-rating rules, and the guaranteed-issue requirements. Scrap the employer mandates and the individual tax penalties. Scrap the "slacker mandate" for those 26 and under. Scrap the guarantee of coverage for pre-existing conditions.

And then keep going.

How to create a mystical cult and live rich and happy, it teaches the Moon’s Sect, excellent child of the statutes ‘non-profit’, which has profited so well, first of all in ‘tax-free’ privileges, to build a substantial business empire funded entirely with funds collected planetary by his followers. The unhealthy seeds of that era, we find them in our time, levied on issues potentially ruinous: a new demographic types living on the costs of the productive society, increases more and more causing the annihilation of the Christian West, where the prize for the tangible merit, it is the key of its success. In this autobiographical book, I tell my twenty years of experience at the service of Sun Myung Moon, a guru determined to take the place of Christ, preventing the notorious discomfort...

JR "So we would expect Brahmins to have higher IQs.  And Brahmins seem well-represented in Indian immigrants to America."

Brahmins are considered the highest caste. They are the most religiously/spiritually disciplined of the castes, and they hold the concept of Brahman, a One omnipresent, all pervasive, ever extensive God, that permeates and envelopes all existence and within and from which all things emerge. The lesser the caste the more fragmented and specialised become the gods, and the more spatially separate becomes reality from the gods. So as with those of Jewish and Taoist descent their belief and hence their mind overlaps reality, their knowledge is ordered as the facts of reality are ordered. Their minds fill in reality rather than search for it. Belief shapes and primes mind, so if one's mind is shaped and primed for reality then one is off to a good start.
