Gee, I always thought that Stanford was in California, thus making them "yanks" too as you put it. The distinction is not between US and international, but between college students and grade school kids. The grade school kids got the answer more often. It highlights the open mind of youth. An open mind would be not jumping to already formed opinions without carefully reading what is presented, in case you were unclear on this point.
Actually, I'm not quite certain the greater number of grade school children correct answers was a result of their open-mindedness. It could be the opposite.
The reason I specified the grade school children as being American was because the United States is often viewed as a nation with a substantial devoted religious population. Now, of course, there are many other nations that have a high percentage of religious citizens, but I chose the United States simply because it is probably the most recognized by those who take part in these forum discussions.
Most children who are raised in whichever religious sects that believe in a bipolar afterlife (Heaven & Hell) are taught that God is the supreme entity of the universe and that NOTHING is greater than He. On the other side, there is the devil, who is illustrated as being the greatest of evils, thus nothing is more evil than the devil.
I suppose what I should have done is said that the children who were given the riddle were from a Christian grade school (FL2 is going to blast me for this), rendering their nationalities irrelevant.
What would be interesting would be the results of the riddle were it to be stated with the first two lines omitted:
What is it that rich people need
Poor people have
And if you eat, will die?
Anyhow, I've gone way off-topic and have probably aided in the destruction of this thread. Sorry
Here's a childhood riddle, since I'm on the theme:
What is black and white and red all over? (Hint: This one is meant to be spoken rather than written) You've probably all heard it as well
