I would like to say that Mtgman has made some good points and has been very articulate in this thread.
We obviously have a lot of science people at the SDMB, who find it shocking and wrong that some people have no interest in science. I too can’t help but feel superior to people who couldn’t answer these basic questions correctly. I like to tell my people the story of how in a group of very intelligent, very well educated law students, I was the only one who knew that spiders have eight legs and insects have six. I also had a lawyer friend who didn’t understand why he has getting a shock when he touched things because he had never heard of static electricity. It seemed to me that he lacked a basic awareness and curiosity about the world around him. But I’m sure if I went to a science class in a top university I would find a large number of people who, for example, do not know that Portuguese is spoken in Brazil (as a friend with a PhD in physics did not). It seems that anyone with any curiosity about the world around them would know what language is spoken in the largest country in out hemisphere, and is more interesting and important to me than how lasers work. Knowledge is better than ignorance, but on a quiz on all the world “basic knowledge,” every single one of us would come up short.
