Final Score: Singapore 103 Jamaica 72

IQ score, that is. An average difference of 31 IQ points between residents of Singapore and residents of Jamaica. A difference of two full standard deviations. So. When comparing the economic output of Jamaicans with Singaporians, you might expect that the IQ difference would play a role. You might if you were intelligent yourself. But if you were a journalist constrained by mainstream rules of political correctness, you might be smarter to play dumb. (via OneSTDV)
.....we can contrast Jamaica and Singapore. Both are relatively tiny states, with under 5 million residents apiece. Upon Singapore’s independence in 1965—three years after Jamaica’s own establishment as a nation—the two nations were about equal in wealth: the gross domestic product (in 2006 U.S. dollars) was $2,850 per person in Jamaica, slightly higher than Singapore’s $2,650. Both nations had a centrally located port, a tradition of British colonial rule, and governments with a strong capitalist orientation. (Jamaica, in addition, had plentiful natural resources and a robust tourist industry.) But four decades later, their standing was dramatically different: Singapore had climbed to a per capita GDP of $31,400 (2006 data, in current dollars), while Jamaica’s figure was only $4,800.

What accounts for the amazing difference in growth rates? _Jamaica vs. Singapore_via OneSTDV
The article makes some good points about the importance of enlightened governmental economic policy toward private enterprise and entrepreneurial activity. That is certainly a factor, but since the per capita GDP of Singapore is 6 times the per capita GDP of Jamaica, it is likely that more than one explanation can fit the data.

When looking at IQ vs the wealth of nations, it becomes clear that the average population IQ of a nation can be an important co-determinant of national economic output. Starting at an IQ of 70, every 10 point rise in average IQ might add as much as or more than $10,000 to a nations' per capita GDP -- assuming a relatively business-friendly government.

A high IQ country can lose its high per capita GDP by letting its average population IQ drop.  Consider immigration:
While the vast majority of young adult children of immigrants experience upward economic and social mobility, a new study finds that a significant minority are suffering from lower levels of education, lower incomes, higher birth rates and higher levels of incarceration. Furthermore, it is the U.S.-born children of Mexican, Haitian and West Indian immigrants who experience these problems in the largest proportions.

The study, led by sociologists Rubén G. Rumbaut of UC Irvine and Alejandro Portes of Princeton University, appears online this week in the Migration Information Source. The largest and longest-running study of children of immigrants yet conducted....

Differences in arrest and incarceration rates are also noteworthy, particularly among second-generation, U.S.-born, males. While only 10 percent of second-generation immigrant males in the survey had been incarcerated, that figure jumped to 20 percent among West Indian and Mexican American youths. _Eurekalert_via_HBDBooks
If a country encourages immigration of low IQ populations with high fertility rates -- particularly when the higher IQ native population has very low fertility rates -- the overall population average IQ will tend to decrease. Poverty, crime, and civil turmoil tend to increase.

Political correctness is the opiate of the masses, in this situation. Just pretend the problem does not exist. The problem will not go away, of course. It will certainly grow worse. But at least you can feel self-righteous on the way down.

There are certainly cognitive differences between Singaporeans and Jamaicans. However, I would go easy on the data provided by Richard Lynn and company. They are known to "cherry-pick" their data to fit pre-conceived notions about the various races. Also, their IQ data representing places like India is completely worthless, because of their failure to account for the demographic complexities of a place like India.

There may be some truth in what you say, but it is not just Lynn and Vanhannen who have devoted many decades to collecting psychometrics data from all over the world.

I recommend the very bottom of the Al Fin sidebar, where there is a list of links to IQ researchers and their work.

Everyone understands that an average is just an average (mean, median, mode etc). It is one number and cannot possibly represent every individual.

Nevertheless, that single number contains an incredible amount of information to those who understand both its strengths and its limitations.

Uh, Yes, please show me one person(Homo Sapiens Sapien) who is different and can be free from all dogmas, prejudices, experiences and wishful thinking.......

I actually think that Jamaica is an example of a country beset by harsh factors rather than having stupid people. Here is why I say it: Jamaicans are more religious and have a higher fertility rate, also keep in mind that since the 70s, the country’s best and brightest have all emigrated to the United States, Canada and of course the UK. The brain drain is so bad that these professionals are paid to return to Jamaica to teach. Many of the remaining Jamaicans are country people who left school to work a farm or do some sort of job to support a family. I wonder if Lynn and Vanhannen used the recent and reliable data when they were researching for Jamaica. If one is to account for a coldly racialist argument, keep in mind that the Chinese, Indian and White Jamaicans who make up a very sizable minority in the country should raise the IQ of the country up at least to the 80s or high 70s. Keep in mind another thing - Zimbabwe has a average IQ score of 82 and they're...well Zimbabwe. So does India...and they are outdone by Eritrea with an average of 85. You wouldn't assume that Eritrea is better than India and for the most part in these cases the cause is education and cultural decline. African Americans have low IQ scores but that problem is that they're in a first world country and have more resources than they're poorer Afro-Caribbean counterparts. Empirically I can tell you that West Indians thrive (at least in America) in the school system with proper conditions (responsible parents and proper guidance etc.) Perhaps because I'm Jamaican, I want to believe that my people in general are a smart and capable group but what we both can agree on is the fact that too many low IQ dubious characters have too many children who they can't take care of.
