This American's stereotype of Poles is that they tend to be big and burly and blond and stout in heart but alas lack some sort of "winning instinct" (despite the presence of many eminent Polish players on the Notre Dame and Nebraska football teams the past 125+ years).
This deal about "being courageous in defeat, pusillanimous in victory" sort of thing, from their history.
However, I hope I'm wrong.
Actually, there was a survey of average IQs that came out a few months ago showing that Poles were in the top 5 WORLDWIDE and were second in Europe behind Sweden, I believe.
The important fact is that they were ahead of Germany!
