"One interesting observation: Almost all cheating happened within ethnic lines. Koreans copy from Koreans. Indians from Indians. Greeks from Greeks. Jews from Jews. Chinese from Chinese."
...or maybe it's just that people copy from their friends?
And their friends are generally within ethnic lines. In engineering school right now. You would have to be blind, or incredibly naive to not see that a majority (I cannot say how great) have their closest ring of friends from the same ethnic backgrounds.
Especially the Koreans. Most tight-knit group I know.
