Ah, the eternal question of who is more intelligent, men or women?
Wait, no, that wasn't your question, though, was it? You were asking about boys and girls. In that case, the answer is neither.
In reading through your posts, and after helping my poor husband in grading the exams turned in by his pathetic college students I've come to the conclusion that 99.999999% of the humans on this planet under the age of 21 are dumb as a sack of hammers, regardless of their sex.
In the sample exchange, the supposed lack of knowledge regarding the relationship of China to Asia was cited as proof of the female's stupidity. I find this to be insufficient evidence for drawing such a conclusion, insofar as neither of the people in this exchange live in China or any other part of Asia. This exchange does, however, bring up a few points.
First, the fact that Asian girls are almost invariably perceived by Western males to be "hot". When I have asked young men to explain this attraction, at some point they admit that they like girls who are submissive. Let us set aside the discussion of whether such submissiveness in Asian girls is accurate - it is perceived, and the perception is an integral part of the attraction.
Second, in my experience, (as well as the experience of every other woman I've ever known) males of all ages are intimidated and therefore presumably turned off by any female they perceive as being more intelligent than themselves. When faced with the prospect of never getting a date, a girl with any intelligence can only respond by playing dumb. Her only other choice is to be true to herself and find herself without a date to the prom, thus condemning herself to a future as a humorless scholar.
Third, most of you young whippersnappers don't really know or care about where any place on earth is in relation to any other part. There are supposedly intelligent college students who were born in and are living in the state of Kansas who can't find it on a map of the United States. I'd be curious to know how many young folks in other places around the world could locate their own home on the globe.
I can hear most of you saying, oh boy, are Americans ever dumb. I'm afraid when it comes to younger people, I'd have to agree with you. (See my statement above regarding hammers...) The frightening part of all this is that one of the requirements for admission to a State university in Kansas is that the applicant has to have placed in the top third of their high-school graduating class. Upon hearing this, my poor beleagered husband exclaimed, "Good God! What must the other two-thirds be like!"
I would like to believe that Kansas is an exception and that graduating high-school seniors in the rest of the country are in better straits. Wrong. According to Department of Education statistics, Kansas is actually above average.
There are times when I truly despair for the future of my country...
But of course, anyone who lives in a factory can't be terribly bright, either...
