I have never had a slightest of doubts in the veracity of the statement I made on many occasions: My children benefited greatly through their experiences of living in a foreign country, and definitely got a leg up on their American peers who did not have such experiences.
Now, there is a scientific study that argues a similar notion. As this article in The Economist describes, the results of a recent psychological study suggest that expats acquire a discernible creative edge over their more stationary compatriots.
I feel validated.
