i would say that's one type of humor, out of many.
for example, things that affirm certain views of reality are also funny. think about humor about relationships, race, culture, etc.

blonde jokes (I'm blonde) are funny because you know a dumb blonde person or it would be without context
I don't think the humor in these jokes has anything to do with truth - they could apply to any group with a reputation for being dumb.
What's interesting is they probably would not be funny if Pole or blonde were just replaced with "idiot," probably because the listener doesn't get to make the logical leap to stupidity themselves. There may also be an element of shame and schadenfreude for picking on a group that adds to the humor.
"Eating rice cakes is like chewing on a foam coffee cup, only less filling."
This joke isn't literally true, but it is true that rice cakes are nasty and not very filling
+1 for blondes! (I'm one, too)
