>> Maybe Asians in America are smarter than the average Asian in Asia - as well as smarter, on average, than other races in (or out of) America <<
Not only smarter, but more motivated. These are people who, for the most part, have VOLUNTARILY left their homelands, to travel across an ocean in search of a better life for themselves and their children.
So as a group, they are a “self-selected” group who have higher IQ’s and higher motivations than do those of their compatriots who remained back in the old country.
Moreover, in addition to the genetic inheritance of IQ’s, the immigrant Asians’ culture of motivation is passed down to their children and grandchildren. The pattern is especially noticeable in the springtime, when photos of high school valedictorians in your local paper will almost always have a disproportionate number of Chinese, Korean, Vietnamese and/or East Indian kids.
In the meantime, those American blacks whose ancestors came over on slave ships tend overwhelmingly to lag behind both in IQ and in motivation, while blacks who move into professional and other high-paying jobs are disproportionately the descendants of ancestors who came to the USA voluntarily from the West Indies and Africa. So again, the black immigrants who pass the formulas for success to their children and grandchildren have largely been a group “self-selected” for relatively high IQ’s and high motivation.
Interesting analysis. It’s a sort of an inverse social Darwinism, where weakness becomes strength and those least deserving of cultural survival are the most likely to survive.
