chinese cleaners smarter than western professionals

here’s the latest re. the most recent pisa test results (various news outlets are reporting that the below also applies to the u.s. and canada – check google news for pisa+oecd):

“China’s poorest beat our best pupils”

“Children of factory workers and cleaners in Far East achieve better exam results than offspring of British lawyers and doctors, says OECD.

“British schoolchildren are lagging so far behind their peers in the Far East that even pupils from wealthy backgrounds are now performing worse in exams than the poorest students in China, an international study shows.

“The children of factory workers and cleaners in parts of the Far East are more than a year ahead of the offspring of British doctors and lawyers, according to a report by the Organisation for Economic Co-operation and Development….

“As part of the study, children were asked to name their parents’ occupation to determine its effect on pupil performance. Across the world, children whose parents work in professional careers generally outperform those in elementary jobs such as caterers, cleaners, factory workers and labourers.

“The study, involving more than 500,000 pupils worldwide, found children of elementary workers in many Far Eastern nations outperformed the sons and daughters of professional British children.

“The children of UK professionals scored an average of 526 points in maths. But this was overshadowed by an average score of 656 registered by the children of professionals in Shanghai-China and 569 among children of the country’s elementary workers. The children of parents in unskilled jobs in the UK scored an average of 461, the equivalent of two and a half years behind.

“Elementary workers’ children in Hong Kong (542), South Korea (538) and Singapore (534), also outperformed more affluent British peers. In Japan, Vietnam, Liechtenstein, Japan and China-Taipei, relatively poor children were only marginally behind the wealthiest British pupils.

“The report said: ‘In the United States and the United Kingdom, where professionals are among the highest-paid in the world, students whose parents work as professionals do not perform as well in mathematics as children of professionals in other countries — nor do they perform as we as the children in Shanghai-China and Singapore whose parents work in manual occupations….'”

no idea if any of these results were broken down by race, ethnicity, etc.

and a related story from a while back:

“Report: Chinese Third-Graders Falling Behind U.S. High School Students in Math, Science”

“According to an alarming new report published Wednesday by the International Association for the Evaluation of Educational Achievement, third-graders in China are beginning to lag behind U.S. high school students in math and science.

“The study, based on exam scores from thousands of students in 63 participating countries, confirmed that in mathematical and scientific literacy, American students from the ages of 14 to 18 have now actually pulled slightly ahead of their 8-year-old Chinese counterparts.

“‘This is certainly a wake-up call for China,’ said Dr. Michael Fornasier, an IEA senior fellow and coauthor of the report. ‘The test results unfortunately indicate that education standards in China have slipped to the extent that pre-teens are struggling to rank among even the average American high school student….'”

intelligence and corruption

staffan already posted about this in his terrific post on corruption a couple of months ago, but i thought i’d just reproduce niklas potrafke‘s chart of the correlation (-0.63) which he found between corruption and iq. taken from this paper [pdf – click on charts for LARGER views]:

potrafke - intelligence and corruption

clearly there’s a connection between intelligence and corruption — the less smart your population is, the more corrupt it will probably be (on average).

i think i see some sub-patterns, though. take a look at this:

potrafke - intelligence and corruption 02

– in my lowest iq range — ca. 75 and below — all the populations are very corrupt — the vast majority fall above 6 on the corruption scale. and they all cluster together — they’re all more-or-less equally corrupt, just some a bit more, some a bit less.

– in my middle iq range — ca. 75 to 95 (i probably could’ve set that at 90) — again the majority of populations are very corrupt, and again the majority fall above 6, but that majority is floating well above that regression line, and the corruption hot spot (where this group clumps together) really seems to be pretty much the same as the lower-iq populations, around 7 on the corruption scale. as a group, they haven’t really dropped down on the corruption scale.

– in my highest iq rage — ca. 95 and above — this is where the corruption range really fans out. we’ve got everything from what looks like below 1 on the corruption scale to an 8 (russia).

and the spread is nice and geographical — west to east/north to south: the anglos and the dutch (and are the scandinavians there? i can’t tell), my long-term outbreeders, are the least corrupt — then, working upwards on the chart (i.e. towards more corrupt) you’ve got the belgians and french and spanish — crossing the line into the more corrupt zone you start to have poland and hungary and the czech republic, places on the border of the hajnal line and the medieval outbreeding project — and then you get up to italy and the ukraine and russia.

east asia is, of course, interesting with singapore, hong kong, and japan being some of the least corrupt, and china being way up by corrupt italy. need to work on figuring out east asia one of these days! (~_^)

so, there’s definitely a connection between intelligence and corruption, but that’s not the whole story, otherwise china and russia and italy and korea wouldn’t be very corrupt at all. one thing that the chinese, russians, and italians have in common (don’t know much about the koreans) is a longer history of inbreeding as compared to the english and the dutch (see mating patterns series below ↓ in left-hand column). the awesome epigone did find a correlation (0.44) between consanguinity and corruption, but like i said then, i’m betting that the correlation would be stronger if we could calculate something like degree+length-of-time inbreeding.
