5% of Americans own a car but not a drivers licence.

I think they should be including a range for the true value for the minorities, since a lot of these numbers are inexact.

I think this bias happens a bit anywhere where there is a limited range to opinion about, may be the interesting part is where is the tilt point, with the corresponding error estimation...

Just like their IQ.

My 3 year old has a college degree? Dang! No wonder I can't understand half the shit he says.

I'm kind of blown away that 88% of Americans have flown on an airplane. If everyone is so broke, how are they affording to fly? And people just don't care about the environmental impact? I've never flown, and I can't imagine I ever will.
