This passage << (It'd be fun to make a whole collection of problems that smart and/or knowledgeable people tend to do poorly on: an anti-intelligence or anti-aptitude test if you will.)

was erroneously attributed to me. (Possibly because in the previous post where it appeared, it was hard to tell who wrote it.) In general I think we in math-fun could be a little clearer about whose passage we're quoting. Also on this subject, I think many posts would be easier to read if they contained quoted material *only* to the extent that it is relevant to what's being posted. --Dan _____________________________________________________________________ "It don't mean a thing if it ain't got that certain je ne sais quoi." --Peter Schickele
