I know that it's edited and selected, so he could go through hundreds of people before finding the ones who can't answer the questions, and then dozens of questions until he finds the ones that stump them. And I know that there could be reasons for ignorance in some cases - maybe some of them were recent immigrants and didn't learn american history from an early age, maybe some of them spoke ESL so that words like dozen/decade were less familiar... if you moved to Sweden when you were ten, learning the language would be the big hurdle, getting the details of their history or geography straight would be more work.

But, even being that generous it's hard to believe some of these answers... How quickly multiple people answered "I don't know" for 3x3x3 was just weird -do they not teach math anymore? And how many didn't know countries from continents or have any idea which ones were where was pretty sad. I am curious what is really average.
