I'd say it's more likely that most of the people taking this quiz have already taken plenty of "biggest cities" type quizes and already have a pretty good idea of which cities will be on here.
For my part, I don't know every location and exact population number for all the cities - especially in China and India - but after I get a few of the regular offenders, I can pretty much guess the less common ones.
The more specialised the quiz, the higher the average for a specific item. Pennsylvania will probably be higher guessed on the 13 Colonies Quiz than the 50 States Quiz and Morrocco on the Africa Quiz than COTW
I find people are quite good at rote memorization of largest cities/capital cities and so on. When it comes to quizzes that require other knowledge, the scores are much more reasonable.
Only 34? Am I missing something or was there a lot more? I checked Wikipedia, and it seemed to confirm this. Not sure what the reason for the discrepancy in the two sites is, but I destinctly remembered Harbin, Lima, Bogota, Xi'an, and a that there were more.
I just assume the people doing this know them already the cities. Many wouldn't dare without knowing what to type, I know all of them just from practice on the one with the map
It says something about the people taking these quizzes when 55.4% get 100%. I doubt that most people (outside China) can name cities like Xiamen and Tianjin. Also, some of the Indian/Japanese cities are probably unknown to most people.
Please remove Seoul. Its population dropped under ten million. I've seen that Seoul has 25 million population in some quizzes but I cannot understand. It only has 9 million.

... Crap, good job guys
Both are big cities
Both are somewhat well known
Neither are the capital
