Is Logic a Fallacy?

One of my readers and friends, Illpallozzo, sent me this last night. I read it, and felt a little ill, but not really surprised.

This anecdote from an unknown person familiar with physics tells a lot about our education system and the common sense/logic/reasoning abilities of our general population. Basically, more than half of people asked (this was at a University, mind you) believed that heavy boots were the only thing holding down our astronauts on the moon, and if they let a pen go, it would float away. Some of the people were disconcerted at being asked things that they had never learned in class, basically the Laws of Physics that govern everything in our known universe. The most important and most readily observed of which, gravity, completely escapes many people. Thinking that the earth had gravity and not the moon is something that never crossed my mind, once hearing that all mass has an attraction to other mass. Logic seems like some sort of arcane magic to some people, a thing that shouldn't be engaged in without years of study. No wonder religion is so prevalent.
It seems that the simpler something is for people to understand (nature, computers, television shows), the more likely they are to appreciate it (rain is wet, Macintosh, Friends). My only true regret is that Darwinism doesn't work as well as it used to, with modern medicine, cell phones, technological advances and all that getting in the way of stupid people offing themselves in various, accidental ways. Now I can't hold just 'people' responsible for their shortcomings, their parents and their schooling are also to blame. How do you reach college age and enter a university without knowing that the moon has gravity? About 1/6th of earth's gravity, if I remember correctly. This seems strange to me, this lack of an ability to logically reach a conclusion without all the information (forced down your mental gullet or not). Maybe someone else can explain this to me without referencing Idiocracy.
