An interesting article in the Boston Globe about the cult of personality tests in the U.S. I think it puts the case quite well - there is value in some of these tests, but clearly they are used far beyond their limits - in situations where they're not meant to be applied, and most particularly, with a blind faith their inventors never intended. (Personally, I always treated them rather like "What does you star sign say about you" descriptions - with amusement, putting credence only in the bits I already believed).

Another interesting article in the Chronicle of Higher Education about the persistent myths of gender differences - not that I think anyone would deny that there ARE gender differences! (actually, I was convinced practically from the moment my son was born) but this whole "men are from Earth, women are from Venus" thing has probably been considerably overplayed - no doubt because it plays into our existing prejudices (hey, we all think the other sex is another species).
