Foreigners who get the chance to visit North Korea — perhaps the most isolated country in the world — are often confused about the age of children. Nine-year-olds are mistaken for kindergartners and soldiers for Boy Scouts.
The issue of IQ is sufficiently sensitive that the South Korean anthropologists [...] have almost entirely avoided mentioning it in their published work. But they say it is a major unspoken worry for South Koreans, who fear that they could inherit the burden of a seriously impaired generation if Korea is reunified.
"This is our nightmare," anthropologist Chung said. "We don't want to get into racial stereotyping or stigmatize North Koreans in any way. But we also worry about what happens if we are living together and we have this generation that was not well-fed and well-educated."
About 500 North Korean children have come to South Korea, either alone or with their parents, and they are known to have difficulty keeping up in the school system, say people who work with defectors.
