The point of the study was, that these characteristics are not inborn - they are learned. And they can be unlearned. It took the Irish 150 years to assimilate into American culture, but once we took hold of it, we flourished. Anybody can do this. It requires a massive overhaul of whatever primitive, tribal culture they started with, however. If they aren't willing to vigorously reject their tribal prejudices and weaknesses and fully embrace Americanism (rugged individualism, Protestant work ethic, thrift, and Christian values), then they don't flourish. You can see a stark difference between those immigrant groups who made that choice, and those among their descendants who have not.
