I’m not sure if the poll was portrayed to be serious.
Also, as someone who was in the US for quite some time, I found that (very much contrary to national stereotypes), Americans were quite knowledgeable about geography and global current affairs. This was evident from the multicultural societies where people knew about their friends, social meetups talking about a lot of different subjects across the world, etc. I refuse to believe that most people are bad at pointing out roughly where different countries are, unless they are countries which genuinely aren’t very well known.
